9. Measurements. Total body length 1.7 mm.; head, length 0.17 

 mm., width 0.2 mm.; prothorax, length 0.16 mm., width 0.25 mm.; 

 mesothorax, width 0.25 mm. ; metathorax, width 0.37 mm. ; abdomen, 

 width, 0.4 mm. 



Antennae: Segment I, 32; 2, 53; 3, 129; 4, 96; 5, 70; 6, 13; 7, 12; 8, 

 15; 9, 12 microns; total, 0.4 mm. 



Color, dark brown with much red pigmentation, which is particularly 

 marked on the lighter pterothorax and base of abdomen. 



Head about one-fifth longer than wide, elevated a little between the 

 antennae ; cheeks slightly arched, diverging very slightly posteriorly ; 

 there are no prominent spines but minute papillae with short hairs 

 occur along the cheeks; dorsal surface with minute cross striations. 



Eyes prominent, black, with large facets, sparsely pilose, oval in 

 dorsal aspect but greatly elongated on the ventral surface, where they 

 end in rather a sharp point. Ocelli present, approximate, the posterior 

 pair not touching the margins of the eyes. 



Mouth cone acute, reaching beyond the middle of the prothorax. 



Antennae nine-segmented, segments I and 2 concolorous with the 

 head, segment 3 and the basal half of 4 yellow, the very tip of 3 and 

 the remainder brown. Sense areas on segment 3 greatly elongated. 

 Spines rather numerous but short. Those on segments 2 and 3 dark, 

 the others colorless. Two on the dorsal surface of the second segment 

 near the anterior end are a little stouter and longer than the others, 

 while between and a little anterior to their bases is a dark, round 

 papilla. 



Prothorax more than half again as wide as long, a little shorter 

 than the head ; sides quite markedly bulging and diverging posteriorly, 

 deeply notched in the middle ; without prominent spines. 



Mesothorax much wider than the prothorax, markedly rounded at 

 the anterior angles, without spines. 



Metathorax narrower than the mesothorax, sides moderately convex, 

 converging posteriorly, no spines. 



Legs rather long, concolorous with the body (i. e., reddish brown) 

 except the tarsi which are light brown, without the reddish pigmenta- 

 tion ; fore femora but slightly enlarged ; tibiae with a short spine at 

 the anterior end. Legs sparsely furnished with short but rather thick 

 curved hairs. 



Wings moderately long, membrane of the fore pair reaching to about
