a pair of slightly two jointed anal prolegs, each with a pair of 
Strong, slender claws and a lateral filament. The antennae 
have six segments, the basal joint being united with the head, 
though Walsh and Riley recognized only five segments. : 
Corydalis larvae collected from different localities haye been 
examined. As they show some variations, a few notes on them 
may aid in future work of determining the species. 
Label, “ Colorado, Chiquili, Dr Newbery, 1873.” Has no tufts 
of hairs on the lateral nor anal filaments. The spongy tufts are 
sessile as in ©. cornuta. Some tufts of hairs near the spir- 
acles on the sides of the abdomen; some yellow markings on 
dorsal aspect of abdomen. 
Label, “ Texas, Stolley, no. 1640.” Has two rows of hairy 
tufts on most of the lateral and on the anal filaments. Thorax 
and head brown with some light yellow areas; abdomen dark 
above with no yellow markings; mesothorax and metathorax 
same color’as the prothorax. aa 
Label, ‘“‘ Mobile Ala., 1853.” Has tufts the same as the above 
Specimen, but the abdomen is very dark, and the clavate projec- 
tions are usually long. Mesothorax and metathorax same color 
as the abdomen; prothorax and head reddish brown without the 
striking light markings; lateral and caudal filaments nearly 
white above. 
Label, “ Rio Negro, Amazon, Thayer Exp.” (about 1869). Has 
the six jointed antennae, and the marks of C. cornuta on the 
head and thorax. It differs from that species in that the spongy 
tufts stand out ventrally from the abdomen, as a pair of fan- 
shaped tufts to each segment. ° 
Label, “ Himalaya, Sutlej river, Bilispur M. M. Carleton: 
1872.” Very light brown or yellowish; reddish yellow on the 
thorax and head. The eight pairs of lateral filaments are 
clothed on the ventral side with tufts appearing like the tracheal 
tufts. A similar growth fringes the abdominal segments. 
Antennae six jointed; ocelli six on each side. , 
Eggs. The egg masses of Corydalis cornuta were de- 
scribed by Riley [1877] who found them in the middle of July 
1876, along the banks of the Mississippi. His description I! 
quote: 
“Theegg mass of Corydalis cornuta is either broadly 
oval, circular, or (more exceptionally) even pyriform in circum- 
ference, flat on the attached side, and plano-convex on the ex- 
posed side. It averages 21mm in length, and: is covered with a 
white or cream-colored albuminous secretion, which is generally 
splashed around the mass on the leaf or other object of attach- 
ment. It contains from two to three thousand eggs, each of
