yellow by reflected light; pilose and rather finely facetted. Ocelli 

 situated well back toward hind margins of eyes, the posterior ones 

 contiguous with inner margins of eyes; the anterior ocellus is on a 

 line mth the middle of the eyes; color light yellow with reddish pig- 

 mentation; mncr crescents large, reddish orange. One small brown- 

 ish spine in front of each posterior ocellus and a similar one imme- 

 diately behind the ocellus. Extending from, the latter spine in a 

 curved row behind each eye to the lateral margin of the head stands 

 six smaller light-bro^vn spines. Mouth cone reaches slightly past 

 the middle of the prosternum, suddenly constricted at the basal 

 tlih'd, thence to the tip the sides are very nearly parallel. Labrum 

 constricted just before the tip, which is black. Labium sharply 

 rounded. First and third segments of maxillary palpi of equal 

 length, second shorter. Relative lengths of segments of antennae as 

 follows, each of which is an average of 4 antennae :

Color: Segments one and two yellowish brown to brown; six to 

 eight brown; three yellow; basal fifth of four and extreme base of 

 five pale gray, remainder of these two brown like the apical seg- 

 ments. Spines on segments light brown, of medium size, and rather 

 sparse. A branched sense cone on the dorsal side of three near the 

 tip and a similar one on the ventral side of four near the tip. 



Prothorax about 0.22 mm. wide and 0.125 long. Sides nearly 

 straight; anterior margin nearly straight; hind angles broadly rounded ; 

 posterior margin slightly convex. Two stout dark-brown spines at 

 each posterior angle; between these spines and the meson on each 

 side a row of three short spines, of which the inner is much the larger. 

 A short anteriorly directed spine at each anterior angle. Dorsum 

 of prothorax bears numerous short light-brown spines scattered over 

 its surface. Whole dorsum rather finely and faintly transversely 

 striate. Mesothorax \\dth front angles broadly rounded. Sides of 

 meso and metathorax straight, gradually diverging to the broadly 

 rounded posterior angles of the metathorax. Metathorax about 

 0.3 mm. wide, scarcely narrower than the abdomen. Mesonotum 

 broad and large, finely transversely ^riatc, its lateral angles ob- 

 tuse; a dark-brown incurved spine at each lateral angle and a 

 smaller spine on each side the meson at about the second third of 

 the length of the notum. Metanotum shield shaped, longitudi- 

 nally striate, except near the central anterior portion, which is 

 transversely striate. Metanotum bears a pair of dark-brown spines 

 on each side on anterior margin, of which the inner spine is much 

 the larger, bemg about two-thirds as large as the spines at the poste- 

 rior angle of the prothorax. Anterior %vings sharp pomted, uni- 

 formly gray brown, the brown due to numerous very small dai-k-
