The distinctions between the tribes above mentioned were founded mostly on insignificant and evanescent modifications in the form of the beak and antennae; so that with the immense mass of genera and species described, it became quite impossible to determine either from the work itself.

John Lawrence LeConte was an American entomologist and physician. He was a chief clerk (assistant director) of the United States Mint from 1878 to 1883.
Background
John Lawrence LeConte was born in New York City, the son of John Eatton and Mary Anne H. (Lawrence) LeConte. John and Joseph LeConte were his first cousins. They were of French Huguenot stock, being descended from Guillaume LeConte, who was born at Rouen in 1659 and migrated to Holland, and thence to America, after the peace of Ryswick in 1698.
Education
He was educated at Mount Saint Mary's College, graduating in 1842, and at the College of Physicians and Surgeons in New York, graduating in 1846.
Career
LeConte never practised medicine for a livelihood, since he possessed independent means. A taste for science seems to have been inherent in the family. His father, a major of engineers in the United States army, was both a zoologist and a botanist. He seems to have been especially interested in the Coleoptera and published especially upon the family Histeridae. He was an excellent delineator of insects. It was natural, then, that John Lawrence, who was the constant companion of his father after the death of his mother in his infancy, should have shared his tastes. While at Saint Mary's College, he collected extensively, and while a medical student, at the age of nineteen, he published his first descriptive paper, on certain Carabidae (Proceedings of the Academy of Natural Sciences of Philadelphia, April 1844).
He soon became interested in the subject of geographic distribution of species, and in one of his early papers wrote of the Coleoptera common to North America and Europe (Annals of the Lyceum of Natural History of New York, vol. IV, 1848, pp. 159-63). Later he studied the distribution of insects in the United States and made broad generalizations applying to other forms of life. He was the first biologist to map the faunal areas of the western part of the United States. It has been said, however, that his very important contributions to zoo-geography were "but accessories to his main work, the overflow of a mind charged with resources" (Scudder, post). Although at first his taxonomic studies resulted in miscellaneous descriptions, he soon began to prepare synopses and monographs. Despite the wealth of material, he worked systematically and carefully. His patient and original investigation may be said to have culminated in his monographic revision of the Rhynchophora ("The Rhynchophora of America North of Mexico, " Proceedings of the American Philosophical Society, vol. XV, 1876), and in his Classification of the Coleoptera of North America (Smithsonian Miscellaneous Collections, vol. XXVI, 1883). In both of these great undertakings he was associated with George H. Horn; but to the first Horn contributed only a single family, the Otiorhynchidae.
In addition to studies in entomology, LeConte published essays dealing with mineralogy, geology, radiates, recent fossil mammals, and ethnology. He kept up with the advance of science, and his breadth of knowledge added authority to his special contributions to entomological science. He was recognized at home and abroad as the greatest entomologist America had produced. European entomologists visited him for consultation, and he was an honorary member of all the older and larger entomological societies in Europe. He was one of the incorporators of the National Academy of Sciences, and was president of the American Association for the Advancement of Science in 1874.
He visited Europe several times. His style was rather scholastic, and his philosophy was rather conservative, although he readily adopted evolutionary thought. During the Civil War he entered the army medical corps as surgeon of volunteers, and was promoted to the grade of lieutenant-colonel and medical inspector, in which capacity he served until the inspectors were mustered out in 1865. In 1878 he received strong indorsements for the post of United States commissioner of agriculture, but President Hayes chose William G. LeDuc, giving LeConte the post of chief clerk of the United States Mint at Philadelphia, which position he held until his death.
Achievements
LeConte was responsible for naming and describing approximately half of the insect taxa known in the United States during his lifetime, including some 5, 000 species of beetles. He was recognized as the foremost authority on North American beetles during his lifetime, and has been described as "the father of American beetle study. "
