antennal groove there is a row of about twelve short hairs in the ¢ and about 
sixin the @. Inthe @ there is no trace of a suture from the antennal groove 
to the vertex. The groove is posteriorly open in both sexes and extends well 
on to the propleura in the ¢. The bristles of the second segment of the 
antenna are minute in both sexes; the club of the antenna is half as long 
again as it is broad in the 2. The maxillary palpus nearly reaches to the 
apex of the forecoxa, and the rostrum extends to the trochanter, but not 
beyond it, as is the case in silantiewt. 
Thorax.—The pronotum bears a comb of 18 pointed spines and a row of 
Io to 12 long bristles. The mesonotum has a posterior row of I0 to 12 
bristles, and before it about 8 to rr small bristles on the two sides together ; 
on the inner side, before the apex, there are 6 to 8 bristle-like spines. The 
mesopleura have 6 or 7 bristles, and at the upper anterior corner a few small 
hairs. The metanotum has 2 rows of bristles, the anterior one containing g to 
12 and the posterior one 11 or 12. The metepisternum bears 2 bristles, 
the sternum 1, and the epimerum 6 to 8 (2 to 4, 3, 1). Metanotum on each 
side with 2 dark brown spines, one such spine being similarly placed on the 
2 or 3 anterior abdominal tergites. 
Abdomen.—The stigmata are situated above the first bristle of the 
posterior row, excepting the seventh segment of the ?, where this bristle is 
absent. The position of the spiracles is different in the sexes, the stigma 
being close to the row of bristles in the ¢, and at a considerable distance in 
front of the row in the 2. The numbers of bristles on the tergites are in the 
anterior and posterior rows of the two sides together in the specimens before

additional bristles in front of the row ; the numbers are on the two sides 
together, inthe ¢: 2,5, 6, 6,6,6;—in the 2: 2,6,6,6,6,8to1r. The 
basal sternite has in addition one or two lateral bristles on each side. There 
are two antepygidial bristles in the ¢, the upper one measuring about one- 
third of the other. In the @ there are three, the upper being about one-fourth 
and the lower four-fifths the length of the central bristle. 
Legs.—The hind coxa has about 7 bristles on the outer side, a row of 8 to 
Io on the inner, and 5 to 7 at the edge, apart from the apical bristles. The 
hind femora bear on the outside 1 to 3 lateral bristles anteriorly, and one 
subapical bristle posteriorly. On the inner surface there is a row of 4 or 5 
bristles on the mid femur and of 5 to 7 on the hind femur. The hind tibia
