The branch nervure dividing the first cubital cell is only indicated 

 by a scar. 



The three apical joints of the maxillary palpi are longer and 

 slenderer than the others.

Type in Oxford University Museum. 

 Allied to the last species, but differs in the form of the 

 mandibles and clypeus, as well as in colour and size.

9 . Mandibles simple, rather short ; labrum prominent ; maxillary 

 palpi short, six-jointed ; labial palpi short, four-jointed. Clypeus 

 truncate at the apex. Head about half as broad again as long, 

 roiuided at the posterior angles, twice as broad as tlie pronotura, 

 finely and closely punctured, with a short, median, longitudinal 

 sulca on the front. Pronotum narrow, longer than broad, the sides 

 almost parallel, strongly convex ; the prosternum narrowly produced 

 anteriorly, forming a neck ; the anterior angles of the pronotum 

 slightly produced. Mesonotum very small and narrowed posteriorly ; 

 the median segment depressed, subtriangular, narrowly truncate at 

 the base, the dorsal surface flat. Thorax and abdomen shining and 

 sparsely punctured, most strongly on the abdomen. First abdominal 

 segment compressed at the sides and strongly elevated to the middle 

 which is subcarinate longitudinally, strongly produced anteriorly on 

 the dorsal surface and overlapping the median segment for nearly 

 half its length, pointed at the extremity and produced into a short 

 bifurcate process. Second segment much broader than the first, 

 with two strong transverse carina), curving forward at the sides, the 

 space between the second carina and the apex almost smooth, the 

 apical margin slightly raised. All the segments, except the second, 

 narrowly depressed on tlie apical margin. Pygidium small, the 

 epipygium ovate, finely rugose, surrounded by a dense fringe of 

 rather short fulvous pubescence, almost vertically truncate, hypo- 

 pygium produced, abruptly widened close to the apex and truncate. 

 The ventral segments more strongly punctured, segments 2-4 with 

 a large broadly triangular depressed surface in the middle of the 

 apical margin. Intermediate coxje widely separated, the intermediate 

 and posterior tibia) hollowed externally near the apex and strongly 

 pubescent. Tarsal ungues bifid. 



Black ; a large spot on each side on the front round the base of 

 the antennae, produced at the sides into a narrow line extending to
