This genus is intermediate apparently between Chiloneurus "Westw. and Corny 8 
Forst. From the former it is distinguished, however, in the 9 hy the pedicel being 
shorter than the first funiclar joint, the more dilated and compressed antennae, 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 antennae, the 
silvery white hairs of the mesonotum, and the very long marginal vein in front wings ; 
and in the $ by having no tuft of bristles on the scutellum. 
Chrysopophagus compressicornis sp. n. 
9 . — Length, 1.6 mm . Head, scape, mandibles, except teeth, prothorax beneath and 
at sides, and mesopleura, brownish-yellow; flagellum and maxillary palpi black, or 
the latter sometimes brown; scutellum orange-red, with a tuft of black bristles; 
mesonotum plumbeous with silvery white hairs; front wings, except base, a small 
transverse streak at tip of postmarginal vein and extreme apex of wing, which are

ish-yellow, the apical joint of all tarsi, the middle tibiae outwardly, and hind femora

$ . — Length, 0.9 nm \ Head, except vertex, scape, flagellum beneath, prothorax at 
sides and beneath, mesopleura, except upper half, which is metallic, and legs, except 
middle tarsi and hind femora tibia? and tarsi, brownish-yellow; middle and hind 
tarsi and annulus at base of hind tibiae white; hind femora and tibiae, except the 
annulus, fuscous; vertex, upper surface of the thorax, and abdomen, metallic green-

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 beneficial, and are attracted to it in search of their prey — 
usually the eggs, larvae, or imagos of other insects. 
During my four weeks' stay in Mississippi, out of many beetles taken 
on cotton I found* only three or four species which fed on it to any 
extent, and the 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 Cicindelidae three species, Tetracha Carolina, L., T. vir- 
ginica, 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 Carabidre were common, the most important 
being Scarites subterraneus Fab. and Pterosticus permiuulus Say. 
Phalacrus politus Melsh. was taken on cotton leaves, but no observa- 
tion on its habits was made.
