lowing it and almost meeting at the center; three hairs, evenly spaced, 

 on the margin between the clypeal suture and the short trabeculae 

 and another one arising on the ventral surface extending beyond the 

 margin at a point between the anterior two of those mentioned above. 

 From a point near the posterior ends of the antennal bands arise two 

 internal bands which extend obliquely inward a short distance, then 

 curve forward and run parallel to the posterior lateral angles of the 

 clypeal signature. A narrow dark band extends entirely around the 

 posterior part of the head connecting the ocular bands ; temples al- 

 most straight and slightly converging behind the eyes, rounded at 

 the posterior angles ; occipital margin concave ; occipital bands nar- 

 row, distinct. Eye prominent with a short hair on the dorsal sur- 

 face and a short spine at its posterior margin ; six short hairs and 

 spines on the temples. Antennae pale, second segment as long as the 

 last two, third segment shortest. In the male antenna the first seg- 

 ment is large and about as long as the following three segments to- 

 gether ; the second segment comes next in length and the fourth is 

 the shortest ; the third has a narrow pointed appendage ; there is a 

 horseshoe-shaped blotch at the base of the first segment. 



Thorax trapezoidal ; prothorax quadrilateral, with sides slightly di- 

 verging behind; coxae show through plainly; length, 16 mm.; width, 

 28 mm. Metathorax length, .36 mm. ; width at posterior angles, .4 

 mm. ; sides diverging behind ; posterior angles rounded ; lateral mar- 

 gins notched at a point about one-third the distance from the an- 

 terior angles with a dark blotch, probably marking the suture be- 

 tween the metathorax and mesothorax. There are six hairs arising 

 from the dorsal surface in the posterior angles ; the outer one is very 

 long and arises from a large curious papilla; the second is short, 

 arising from a small papilla ; the other four are very long and close 

 together in a group. (See b, Fig. 2.) 



The abdomen is long and rather narrow, expanding slightly to the 

 fourth segment which is widest; last segment bilobed, straight across 

 the posterior margin in the male. There are narrow dark lateral 

 bands on each segment except the last and transverse blotches, which 

 extend about a third the way across the body, and there are also 

 faint lengthwise median blotches. Each lateral band extends into 

 the segment in front and has two long appendages which curve back 

 making a clear space in the anterior margin of the transverse blotch 

 of the segment to which the lateral band belongs. The blotch on 

 the last segment is median and bilobed; the margin of this segment 

 is transparent. There are about six hairs on each segment except the 

 last, and several hair's in the posterior angles. In the male the pos- 

 terior margin of the last segment is straight. The genitalia of the 

 male are as shown in Fig. 2, d.
