pronotum about equals the interspace betweeu the first and fifth spines. The 

 lengths of the three thoracic tergites are snbdorsaily 24, 30, 25. The metepisternum 

 is ver}' much higher than it is long. The lower half of the distal margin of the 

 metepimerum is incurved, so that the apex of this sclerite is almost pointed ; the 

 dorsal portion of the apical margin is rounded, the outline being, however, slightly 

 variable. The metepimerum has two or three long bristles below the stigma, and 

 in front of this row about eight or nine small ones, irregularly distributed. 



Abdomen. — The tergites I to VI in c? and I to V in ? bear dorsally on the 

 two sides together two to four apical spines. The postmedian row of long bristles 

 contains about twenty-four bristles on the two sides together. The small bristles 

 placed betweeu the long ones are very thin, while the short bristles which are placed 

 in front of the long ones, and of which there are one to three rows, are remarkably

thick. The row of long bristles curves backwards dorsally, and the second to 

 fourth short lateral bristles of the second segment point obliquely downwards. 

 The basal sternite has ventrally one pair of bristles and some very minate hairs, 

 the following sternites bearing on the two sides together a row of twenty to twenty- 

 four long bristles, and a small number of additional sliorter bristles. 



Legs. — The bristles on the coxae, femora, and the outside of the tibiae are 

 small. The subapical posterior sinus of both the mid- and hindcoxae is small and 

 nearly semicircular, the angle above the sinus is prominent, as the hindmargin 

 of the midcoxa is rather abruptly incurved above this angle and that margin of 

 the hiiidcoxa gently incurved from the angle to beyond the centre. The apical 

 lobe is broad in both these coxae. The forofemnr has several small hairs on the 

 outer surface. Tlie hindfemnr bears six or seven suhventral hairs on the outside, 

 inclusive of the subapical bristle. The mid- and hindfemora have six or seven
