and a short, more or less curved line, on basal joint of antennae, and 
two short black lines on the second joint, the outer being the shorter. 
The eggs are deposited in double rows in long slits made by the ovi- 
positor of the female, in the smaller lateral branches or the leaf-petioles 
of the cotton. Each egg is very elongate, 3 mm long, or over five times 
as long as thick, perfectly white, and with a granulated cap at the top 
or outer end. The duration of the egg stage is from four to five days, 
although it may be even shorter, as apparently fresh specimens taken 
in the petiole of a leaf on August 3 hatched August 6. Other speci- 
mens taken August 5 hatched August 9. 
The cone-headed locust {Conocephalus obtusus Burm.). — Only occa- 
sionally met with on cotton. It feeds on the leaves, eating large pieces 
out of the sides and gnawing holes through the middle. 
Two nymphs of another species, or belonging to another genus, were 
also taken feeding on the leaves. This species has an acute tubercle 
on the forehead and white rings on the antennae. 
The long-tailed cotton locust (Orchelimum gossypii Scudd.). — This 
species is in the National Museum labeled 0. longicatida Walsh, but so 
far as I can find was never described by him. 
Mr. Samuel H. Scudder in "Entomological Notes" (pt. iv, p. 64) 
described it under the name 0. gossypii, and says: "This is the insect 
referred to in the Proceedings of the Boston Society of Natural History 
(vol. xi, p. 434) as laying its eggs in the stems of the cotton plant. The 
eggs were pale yellow, one-fifth of an inch long, cylindrical, bluntly 
pointed, and a little tapering at the end from which the larva emerges ; 
the other extremity was rounded." 
I found the species common, feeding in the blossoms, eating the 
corolla and petals, and preventing the formation of the boll. The 
species is very voracious, and a single specimen must destroy many 
bolls before attaining full growth. 
Two other species with similar habits, 0. glaberrimum Burm. and 0. 
fasciatum Scudd., were observed. 
The red-legged locust (Melanoplus femur-rubrtim DeG.). — Taken in 
both nymph and imago state, feeding on the leaves. 
The obscure grasshopper (Acridium obscurum Burm.). — Very com- 
mon. Feeds in the nymph stage upon the leaves, and sometimes almost 
entirely defoliated some of the branches. In destructiveness it comes 
next to the long-tailed cotton locust. 
The rugose grasshopper (Hippiscus rugosus Scudd.) — Although plen- 
tiful in all the fields, this species was only occasionally seen feeding on 
cotton leaves. 
In the family Tettigidae five distinct species were taken on cotton, 
as follows: Batrichidea cristata Scudd.; Tettigidea lateralis Say; Tettix 
ornatus Say; T. femoratus Scudd.; and T. are?iosus Burm.
