orange. In some specimens the orange color forms a small elon- 

 gated blotch or streak posteriorly on either lateral margin; other 

 specimens have the mesoscutum more extensively orange colored, 

 the pattern arranged so that the blackened portion is in the shape 

 of a V. Scutellum mostly, if not entirely, orange colored, some- 

 times the base very narrowly black. Median part of metanotum 

 yellow. Parapsides orange and black. Legs mostly lemon yellow; 

 basal half of hind tibiae and somewhat more than the basal half 

 of hind coxae black; middle coxae touched beneath with black; 

 apical two or three tarsi of hind legs fuscous ; apical tarsi of middle 

 legs fuscous; all tarsi of fore legs faintly fuscous. Tibiae not pure 

 lemon yellow like the femora but with a faint suffusion of brownish. 



Pedicel small, hardly longer than wide and about one-third as 

 long as the first funicle joint. First funicle joint plainly the 

 longest, more than twice as long as wide; second and third joints 

 each plainly shorter than the preceding, the third about two-thirds 

 the length of the first. Club about as long as the first two funicle 

 joints combined and not much wider than the funicle. Funicle and 

 club furnished with numerous sensoria which on the third funicle 

 joint and on club joints extend the entire length of the segments; 

 sensoria on the first two funicle joints approximately one-half as 

 long as the segment on which they occur (fig. 28). 



Mandibles with one small ventral tooth and a broad, dorsal 

 truncation (fig. 170). 



Fore wings hyaline. Marginal vein about as long as the sub- 

 marginal vein; stigmal vein as shown in Figure 126. Disk of wing 

 with abundant small cilia. Marginal fringe very short. 



Scutellum convex, slightly wider than long (24:21) and not 

 quite so long as the mesoscutum (21 : 22). Abdomen about as long as 

 the thorax; seventh tergite long. Ovipositor shortly exserted. In 

 dried specimens the abdomen is strongly laterally compressed. 

 Thorax and abdomen as shown in Figure 11. 



Basitarsus of middle legs not quite as long as the succeeding joints 

 united; tibial spur slightly shorter than the basitarsus. Paired 

 spurs of hind tibiae plainly of unequal length. 



Mesoscutum densely setose. Scutellum with three pairs of strong, 

 black bristles. Each parapsis with three setae about as strong as 

 those of the mesoscutum. Each axilla with two setae somewhat 

 stronger than those of mesoscutum. The transverse rows of setae on 

 the abdomen incomplete on the dorsum of the first, second, and 

 third tergites. 



Measurements in mm.: Length 1.1. Scape 0.1464 long by 0.04
