Head about 1.2 longer than wide and considerably longer than the pro- 
thorax, smooth except for a few longtitudinal lines; cheeks slightly arched, 
slightly converging posteriorly, roughened; post-ocular bristles about as 
long as the eyes, knobbed, pale, no other prominent bristles on the head. 
Eyes rather small, scarcely a third the length of the head, roughly triangular 
in outline, dark. Ocelli large, yellowish brown, well separated; posterior pair 
situated opposite the middle of the eyes, close to, but not touching, their 
margins; bordered by narrow orange crescents. Mouth cone reaching .6 
the distance across the prosternum. Antennae about 1% as long as the 
head, segment 1 concolorous with the head; 2 lighter brown, urn-shaped 
with a broad pedicel; 3 yellowish-brown, almost triangular; 4 brown but 
lighter than 5-8 which are uniformly dark brown, conspicuously the largest 
segment; 6 conspicuously short and narrow, ovoid; 7 barrel-shaped; 8 
conical. Bristles and sense cones pale and inconspicuous. 
Prothorax (including coxae) fully twice as wide as long, trapezoidal in 
outline; posterior angles well rounded, bearing a single pale, knobbed 
bristle of medium length, a somewhat longer one on each coxa, also knobbed; 
a minute bristle on each anterior angle. 
Mesothorax somewhat narrower than the prothorax, sides converging 
sharply posteriorly. Metathorax, sides nearly straight and parallel. Wings 
short, membrane reaching to about the middle of the abdomen, colorless 
except for a brown area at the base; fringing hairs long but sparse, 2 or 
3 interlocated ones. Legs short; fore femora much thickened, with a long 
bristle and two shorter ones on the inner side; fore tarsus with a curved 
tooth, which is variable in size. 
Abdomen cylindical, segments 2-9 bearing on each posterior angle a 
knobbed, almost colorless bristle, which become progressively larger pos- 
teriorly; segments 7-9 bear in addition from one to three pairs of pointed 
bristles, two pairs of these on the ninth segment are much longer than 
the tube, a pair of knobbed bristles nearly or quite as long as the tube 
arises from the ninth segment adjacent to the base of the tube. 
Male. Somewhat larger than the female; prothorax much smaller. Gen- 
eral color brownish yellow, head, prothorax, and fore legs yellowish brown, 
pterothorax and middle and hind legs light brownish yellow with darker 
spots; abdominal segments 1 and 2 light yellow, 3, 4, 8, and 9 deep yellow, 
3 and 4 with brownish anterior margins; 5 light brown, 6 dark brown, 7 
yellowish brown, 5 and 6 forming a conspicuous dark band; tube brownish 
yellow. Fore wings banded with brown in the middle and at the tips; no 
interlocated hairs. Hind wings shaded with brown but not banded. Fore 
femora enlarged but much smaller than those of the female. Terminal 
bristles of the abdomen and of the tube much shorter than in the female. 
Labrum shorter, barely exceeding the remainder of the mouth cone. No 
tarsal teeth. 
Described from two females and a male collected by Mr. C. A. Weigel
