position is reached which it has in our drawing. The hind side, 

 which bears the long bristles, is nearest to the eye when the 

 antenna is in the groove, and it is always the outer surface which 

 is jaresented. 



Head. — The rostrum is a little longer in the § than in the 

 J . It reaches beyond the trochanter in both sexes, the apex 

 of the fourth segment being on a level with the base of the 

 trochanter and the last segment being more than twice the length 

 of the fourth. The maxillary palpus extends to the third 

 segment of the rostrum. The bristles of the head are almost the 

 same in number in the sexes {cf. text-fig. 106), but are less strongly 

 developed in the 5 than in the J ; moreover, the thin bristles 

 at the anterior edge of the antennal groove are not present 

 in the $ , and of the four bristles placed in the cJ above the 

 antennal groove (1, 3) the anterior one is absent, and the lai-ge 

 ventral one of the row of 3 is accompanied by but one bristle, 

 which is small. The first antennal segment of the S bears on 

 the inner surface a number of small bristles along the anterior 

 edge, and the outer surface of this segment of the $ has 

 numerous small hairs. The second antennaJ segment of the $ 

 bears one row of short hairs, these hairs being ^ery thin and only 

 reaching to the second segment of the club. In the S this segment 

 has several very long bristles, as shown in the figure. 



Thorax. — The pronotal comb consists of 18 to 20 spines. The 

 meso- and metanotum bear each two rows of bristles and a 

 number of additional short bristles which represent three more 

 rows on the mesonotum and two on the metanotum, being less 

 numerous on the latter than on the former. The mesonotum 

 has on the inner side eight slender spines on the two sides 

 together. The mesopleura bear 9 to 11 bristles, the metepister- 

 num 3 and the metepimerum 7 or 8 (3, 3 or 4, 1). There are 

 2 or 3 apical spines on the metanotum on the two sides 

 together. 



Abdomen. — The four to six anterior tergites bear apical spines, 

 the numbers being (on the two sides together) in the S 2 — 3 or 

 4—2—2—2—0 or2,and in the 2 2 or 3— 2 to4— 2— 2. Theapical 

 edge of segments I to Vll is distinctly denticulate in both sexes. 

 There are two rows of bristles on the tergites. The stigmata are 

 placed above the first bristle of the second row, and below the 

 first of the anterior row. The S has one very long antepy- 

 gidial bristle accompanied by tw'o short but strong ones, the upper 

 one being the shortest. The $ also has three antepygidial 

 bristles, of which the upper one is half and the lower one two- 

 thirds the length of the central bristle, which is as long as the 

 first hind-tarsal segment. The first sternite has (on both sides 

 together) two bristles, ste]:-nites III to VII beai"ing in the S 

 6 bristles, and III to YI in the 2 6 to 8, while YII has 10 to 12 

 in the $ , with one or two small bristles in front of this row, 

 there being no additional bristles or quite exceptionally one 

 bristle on the other sternites.
