In 1860, Clemens described twelve species under the genus 

 Crambus, in the "Proceedings of the Academy of Natural 

 Sciences of Philadelphia," one of which, auratellus, belongs 

 in the genus Argyria. In the same paper he published 

 three species and placed them under the genus Chilo, but 

 they did not belong there, and have been more correctly 

 placed under the genus /Schoenobius, which is not now re- 

 garded as belonging to the Crambidce. In 1863, Walker, 

 in his " Cat. Lep. Het.,"part XXXVII., adopted the family 

 name Crcnribidw, with Chile, Crambus and several other 

 genera under it. Several North American species were 

 described for the first time in this work, and some others 

 were re-described. In a few cases the descriptions were 

 made from very poor specimens, and it is not only impos- 

 sible to determine the insects from his description, but very 

 difficult to decide what they are from the types. In 1863, 

 Zeller published a valuable work entitled " Chilonidarum et 

 Crambidarum genera et species," in which he dealt with all 

 the described species, and published many new ones from 

 North America, as well as elsewhere. This work, although 

 appearing in the same year as Walker's, was not published 

 till July, while Walker's catalogue was published in April. 



In 1866, Packard described two species of Crambus from 

 Labrador, in the ' * Proceedings of the Boston Society of 

 Natural History." Grote published several species, with a, 

 list, in the "Canadian Entomologist," in 1880; and Hulst 

 described several species in the "Transactions of the Amer- 

 ican Entomological Society," in 1886. 



In 1894, Felt published a paper " On Certain Grass-eating 

 Insects," which deserves more than a passing notice. In this 

 paper, for the first time, a special study was made of the early 

 stages of a large number of our species, including their habi- 

 tations, etc. There is still much to be done in this direction, 

 and it is sincerely to be hoped that the work, so well begun 

 by Mr. Felt, may be continued till we have a complete his- 

 tory of all our species of this family. I should mention, in 

 this connection, the work done by Forbes on the early stages 

 of zeellus, by Howard on saccharalis, by Miss Murtfeldt on 

 teterrellus and by Scudder oujiortuettus.
