An elegant yellowish species, heavily striped with brown, and with a red- 
tipped abdomen. Face and occiput yellow. Thoracic stripes of the first pair 
strongly widened forward, wider than the bordering yellow stripes, separated 
narrowly by the yellow of the carina, confluent at the crest with the incurving 
stripes of the second pair. Stripes 2 and 3 fused more or less extensively at the 
shoulder, usually in such way as to leave a pale spot above and a streak below 
them. Stripe 2 is much wider than 3. Stripe 4 is narrow and interrupted in the 
middle, plainest below the spiracle. Stripe 5 is very narrow. Wings hyaline, 
veins brown, stigma reddish brown when mature. Legs black from a little before 
the knees, their bases yellow. Dorsum of abdomen obscure blackish, the middle 
segments obscurely ringed with paler basally. Segments 7 to 10 are reddish 
brown, yellow at the sides. Appendages yellow. 
This species was observed by the senior author at Havana, Ill. in
