SPRING NUMBER 53 
distinct cross band near the apex of the elytra. Length, 4.52 
mm.; width 3 mm. 
Hood moderately large, constricted slightly back of the middle, not so 
strongly deflected as in unifasciata Champ., slightly broader than high, 
its length about one and a half times its height. Median carina moderately 
arched, with single row of areolae (two or three extra cells at middle), 
about one-half as high as hood. Lateral carinae with five or six small cells, 
rather widely separated from hood. Costal area with three quite regular 
rows of large areolae. Bulbous elevations of elytra moderately large. 
Outer margins of elytra and paranota armed with numerous short spines. 
Nervures of elytra, hood and paranota with few spines. 
General color above yellowish brown. Areolae mostly hyaline. Two spots 
on the paranota, a rather large spot on median carina, part of crest of 
hood, most of tumid elevation, and more or less of sutural area brown. 
Elytra with a transverse band near the base and another near the tip 
brown. Spines with black tips. Body black. 
Four specimens, Cochabamba, Bolivia, S. A. Names in honor 
of Mr. E. Seguy, who kindly sent the material to me for study. 
Types in Paris Museum. Paratypes in my collection. The type 
is figured. More specimens may make this species a variety of 
C. unifasciata, but at present it seems best to consider it a dis- 
tinct species. 
Corythucha salicata Gibson. 
In a long series of specimens from Oregon, Washington and 
Manitoba it is impossible to separate C. drakei Gib. from C. 
salicata Gib.; the latter name has priority. The insect feeds on 
willow, poplar, apple and alder. 
Corythucha mollicula Osborn and Drake. 
Numerous specimens at hand from Wisconsin, Michigan and 
New York positively connect up C. salicis O. & D. with C. molli- 
cula O. & D. The species is quite variable in color and size; the 
hood is also somewhat variable in size and height. Mollicula 
and salicis represent the two most extreme forms before me, but 
as there are so many intermediate forms, it seems best not to 
consider the latter as a variety. The insects breed on various 
species of willows and poplars. It has been collected on culti- 
vated currants in Montana by Cooley. There are two genera- 
tions a year on willow and poplar in the Adirondack Mts., New 
York. Winter is spent in the mature state among the leaves and 
rubbish on the ground. The insect is a transcontinental species, 
extending throughout the northern part of the United States 
and southern part of Canada and south along the Atlantic states 
to South Carolina (fide Drake) and Florida (fide Osborn).
