frontal tubercle being placed at one-third or one-fourth the 

 distance from the oral corner to the antennal groove. There are 

 two long bristles in front of the eye, one of them standing near 

 the eye and being accompanied by a much shorter bristle, and 

 the others being placed at the oral margin. Further frontad 

 there are two more bristles in the J , but not in the 5 , one of 

 them at the oral margin behind the maxillary palpus and the 

 other near the antennal groove. On the occiput there is one 

 bristle above the antennal groove, and along the groove about 

 half-a-dozen small hairs in both sexes. The apical row of bristles 

 contains 1 long and 3 or 4 small ones, the interspace between the 

 long (ventral) bristle and the next one being large. The third 

 segment of the maxillary palpus is comparatively long, being only 

 one-eighth shorter than the second segment. The rostrum 

 reaches well beyond the trochanter, the proportional lengths of the 

 segments being, 16, 15, 15, 27, and 40. 



Thorax. — Thepronotum has a comb of 18 spines (in one of the 

 females 23) and a row of 12 bristles on the two sides together. 

 On the mesonotum thepostmedianrow consists also of 12 bristles, 

 while the row before it contains from 8 to 10. Near the base of 

 the mesonotum there are only 14 small hairs in the cS and 24 in 

 the 2 > while the inner svirface bears near the apex from 9 to 

 12 bristle-like spines. The inesopleui'a bear five long bristles and 

 anteriorly a few small hairs in addition. The numbers of bristles 

 on the metanotum are 12 in the postmedian row in both sexes, 3 to 

 5 in the anterior row in the d and 9 to 1 1 in the 2 • The metepi- 

 sternum bears 2 or 3 bristles and the epimerum 5 (2, 2, 1). 

 There is on each side one apical spine on the metanotum, as on 

 the first to third or fourth abdominal tei-gites. 



Abdomen. — The tergites I to YII bear in the $ each two rows 

 of bristles, the postmedian row containing 13 or 14 bristles on the 

 central segments ; in the S the anterior row is reduced to 4 to 6 

 bristles on the first to fourth segments and to one or two on 

 segments Y and VI. The seventh tergite bears on each side in 

 the (S one long antepygidial bristle accompanied by two minute 

 hairs, and in the 5 two long bristles, of which the lower one is a 

 very little shorter than the other. The numbers of bristles on 

 the sternites are in the cj' 2 — 4 to 6 — 6 — 6 — 4, and in the $ 

 2—12 to 14—8—7 to 10—8—13 or 14, there being 3 or 4 small 

 bristles in front of the row of the seventh segment on the two 

 sides together. 



Legs.— The hind femur has on the outside two lateral bristles 

 and one subapical one and on the inside a row of 7 or 8 bristles. 

 On the hind tibia there is one lateral row on the outside, 

 containing in the c? 7 bristles and in the $ 5 to 8, the inner 

 surface hearing a I'ow of 4 to 7 in the d and of 6 to 8 in 

 the 2 • 1'^^6 fii'st mid-tarsal segment is the same in length as the 

 second. The longest bristle of the first hind-tarsal segment 

 reaches at least to the apex of the second, and this latter segment 

 beai'S two apical bristles which extend considerably beyond the
