narrowest, while the lateral ones are abbreviated behind. The front of 

 the head is brown, while the jaws and other mouth parts are nearly black. 



Like all insects, these beetles, both as larvae and imago, are very sus- 

 ceptible to gasoline or bi-sulphide of carbon. Both of these, used in large 

 quantities, were quickly fatal to the insects. Like the carpet beetle, they 

 infest upholstered furniture between the folds, especially where the back 

 joins the seat. It is easy to drench such parts of a sofa or chair with 

 gasoline and destroy the larvte of either moth or beetle. 



Nearly every year brings examples of such change of habits as de- 

 scribed above. Such incursions, present and prospective, emphasize the 

 importance of thoroughly-trained entomologists in every state of our 

 country.

Tribe Agrotini. 



The tibiae are usually all spinose, the eyes naked, the body untufted, 

 the form normal, the male antennae of various structure, pectinated, brush- 

 like, simple. The European species are referred by Lederer all to one 

 genus, Agrotis of Hiibner. Nevertheless, I think the yellow-winged 

 forms may well be separated under Hiria and Try.phcena. Of these 

 yellow-winged forms, with flattened abdomen, we have only one T. 

 Chardinyi, from Anticosti and Maine, considered identical with the 

 Siberian species of the same name, described originally by Boisduval under 

 Anarta. For the structure of Agrotis, I refer the student to a paper of 

 mine on the genus, Can. Ent., XV., 51. This genus seems of general 

 distribution, although, perhaps, most numerously represented by species 

 in North America. To this tribe, I would refer certain American genera, 

 with few species, which seem peculiar. These are : Carneades, which 

 differs by a frontal tubercle ; Richia, which resembles Ammoconia in 

 having a thoracic rigid tuft, but has simple antennae ; Adita, with a claw 

 on front tibise ; Agrotiphila, with narrowed eyes 3 Anyttis, with lashes _; 

 the peculiar genus Ufeus, and, finally, Copabiepharon, which has some
