This genus ia intermediate apparently between CliiloiienrKS Westw. and Comys 

 Fiirst. From the former it is dlHtingnished, however, in the 9 by the pedicel being 

 shorter than the tirst funiclar joint, the more dilated and compressed anteunie, and 

 the longer marginal vein ; in the ^ by the longer marginal vein and the. hairs on 

 the antenna- not being arranged in half whorls; from the latter genus it is readily 

 separated in the 9 by its more slender form, a marked difference in the antenna-, the 

 silvery white hairs of the luesonotum, and tlie very long marginal vein in front wings ; 

 and in the ^ by having no tuft of bristles on the scutellum.

ORDER COLEOPTERA. 



In the United States, cotton is singularly free from the attacks of 

 insects belonging to this order. I do not know of a single beetle that 

 in any sense could be considered a serious enemy of this crop, and, 

 indeed, not a single case that I can recall is mentioned in our literature 

 on the subject. The beetles found on it are, with few exceptions, 

 more or less benellcial, and are attrticted to it in search of their prey — 

 usually the eggs, larvie, or imagos of other iusects. 



During my four Aveeks' stay in Mississippi, out of numy beetles taken 

 on cotton I found only three or four species which fed on it to any 

 extent, and tlie injury done was comparatively slight. The vast 

 majority of those taken were predaceous or pollen-feeders, and should 

 be classified among beneficial species. 



In the family Cicindelidie three species, Tetracha Carolina L., T. vir- 

 ginicaj and Cicindela 6-punctata, known to be predaceous in both larva 

 and imago stage on the cotton-worm and other insects, were captured 

 in the cotton fields. 



Several small species of Carabidse were common, the most important 

 being Scarites subterraneus Fab. and Pterosticus permnndus Say. 



Phalacrus politus Melsh. was taken on cotton leaves, but no observa- 

 tion on its habits was made.
