The scutellum and wing covers are black, tinged with yellowish, 
and nearly unicolorous except at the sides, where they are broadly 
margined with yellow. The cuneus is more or less tinged with red, 
being sometimes almost carmine. The membrane is uniform dusky, 
the veins black. The wing covers are more coarsely haired than 
the thorax, somewhat more evidently punctured, and minutely 
rugulose, as is also the scutellum, which is lhkewise of the same 
color as the wing covers. 
The abdomen is black, with a red vitta upon either side, which 
is often interrupted on the posterior half of each segment, and con- 
tinued forward on to the thorax, where the color changes to yellow. 
The last segment of the abdomen is wholly red. 
The thighs are brown, tinged with reddish, the tibiz yellow, and 
these and the tarsi tipped with black. The tibize are very strongly 
spinose, the posterior, especially, being armed on all sides with 
peu black spines; and the thighs are provided with similar spines 
within. 
Second Stage.—No examples of the species in the first stage 
were found in our collections. In the second stage, it is easily 
recognized by the fact that the head, prothorax, and middle of the 
abdomen are red, the intermediate region being yellow or green. 
Another distinguishing characteristic is the snow-white tip and basal 
ring to the terminal joint of the antenne, the remainder of the 
joint being red. In this stage the species is about .08 of an inch 
long, and .04 wide. 
The head is smooth,.a little wider than the prothorax, and pro- 
vided with a very few, scattering, black hairs. The prothorax is 
narrower than the remaining segments, smooth and shining. The 
mesothoracic segment is about twice as long as the metathoracic, 
both being green or yellow in color, and sparsely provided with 
black hairs. ‘Their posterior angles are free, projecting very slightly 
backwards. The first two abdominal segments are closely united 
and very short. The abdomen expands considerably, its general 
outline being broad ovate, widest before the middle. The color 
beneath is red, except at the middle of the base of the abdomen, 
where it is green. The femora and tibiz are red, the tarsi white with 
black tips. ‘The rostrum is very long, reaching to the fifth abdom- 
inal segment. The antenne are likewise long, the tip of the third 
joint attaining the end of the abdomen. They are pale in color at 
the base, reddening distally, the terminal joint being variegated 
with white, as already mentioned. 
Third Stage-—This stage is distinguished chiefly by the more 
advanced development of the second and third segments of the 
thorax, the posterior angles projecting backwards, making the hind 
margin widely emarginate. The scutelluam is now outlined by a 
v-shaped groove upon the second segment. The abdomen 1s tinged 
with red, and the colors remain in general as in the preceding stage. 
The antennez, however, are now red throughout, with the exception 
of the bases of the second, third, and fourth joints, and the tip of 
the latter, all of which are white. They are still considerably longer
