pronotum is provided with two conspicuous black collar-like bands, 

 one median and the other just back of the anterior edge. The abdo- 

 men is alternately yellow and black-banded, the pleura obliqueU^ yel- 

 low and l)lack alternately and the venter yellow\ The teg-mina have 

 the longitudinal veins yellow and the interspaces transparent bluish 

 lead color, which when folded over the cterulean wings gives to them 

 the appearance of being alternatel}^ dark and pale streaked. The head, 

 front, and middle femora, coxa3, and knees of hind legs red, hind 

 femora and tibiae j^ellow, the former thrice banded with black, the 

 latter basally and at the apex also black, tarsi and apex of remaining 

 tibia) likewise black. There are also black bands on both the middle 

 and anterior femora. 



The characteristic feature of this species, however, is the ver}^ long 

 last ventral segment of the male abdomen, which is fissured to its 

 base, giving to this region the appearance of being provided with 

 exceedingly long cerci which cross at their apices scissor-like. 



Length of bod}', male, 35; female, 45; of pronotum, male, 6.4; 

 female, 8.5; of tegmina, male, 33; female, 40; of hind femora, male,

ZONIOPODA EXILIPES, new species. 



Very similar in general appearance to Z. omnicolor Blanchard, but 

 differing from that species in the absence of reddish tints about the 

 head and the longitudinal bands on the pronotum. It also differs 

 from that insect by lacking the bands on the anterior and middle legs. 



Head a trifle inflated, smooth; the vertex rather broad, one and one- 

 half (male), or nearly twice as wide (female) as the shortest diameter 

 of the eyes, separated from the occii)ut by a well-defined transverse 

 impression; frontal costa rather broad, continuous to cl3'peus, the sides 

 pinched below the ocelus, flat and coarsely punctate above, sulcate at 

 ocellus and for one-half the distance below; antennie black, nearl}' or 

 quite as long as the hind femora. Pronotum with the anterior lobe 

 smooth, tripartite, subtectate on the dorsum, the transverse sulci 

 broad and deep; posterior lobe flat above, closel3Muid finel}' granulate, 

 the median carina blunt, hind margin obtuse-angled, front margin entire 

 subangled. Tegmina complete in the male and slightly surpassing 

 the tip of the alxlomen; in the female somewhat abbreviated, a little 

 more than half the length of the abdomen. Hind femora ver^'^ slender, 

 not reaching the tip of a])domcn even in the male: middle and anterior 

 femora also slenderer than usual in the genus. 



General color glossy black, varied on the margins of the face, the 

 anterior and posterior edges of jn-onotum, the hind edges of meso- and 

 metathorax and abdominal segments, as well as on the front and hind
