fourth and fifth together, cylindric. 4-8 successively shorter and 
wider, subconic, 9-11 much shorter than preceding', narrower 
than 7, rounded. Prothorax 6.5x11 mm. (length measured in 
middle), widest behind the middle, wider at base than at apex 
(10.5 and 7 mm. respectively), apex widely emarginate, acute 
anterior angles produced obliquely outwards, sides behind front 
angles slightly, before hind angles strongly sinuate, between these 
sinuations widely rounded with a strongly thickened, rounded, 
raised, and nitid border, posterior angles very acute, dentate, 
directed outwards and a little downwards ; basal border narrower 
but evident throughout, apical border wider than basal but much 
narrower than lateral, obliterated in the middle ; disc finely, dis- 
tinctly canaliculate, very minutely and closely punctured, 
moderately convex and somewhat explanate laterally, with a wide 
gutter within the border continuous throughout. Scutellum very 
transverse, raised and emphasized by deep triangular depression 
behind it. Elytra 16 x 14 mm., widely oval, very convex, wider 
than prothorax at base, shoulder obsolete, widest at middle ; 
steeply declivous and widely rounded at apex, very narrowly 
margined and channelled throughout, suture transversely deeply 
depressed behind scutellum, less deeply longitudinally for a short 
distance behind this, then with stitch-like impressions forming 
short transverse' costa? till near apex ; whole disc microscopically 
punctured and showing under a strong lens faintly vermiculate 
reticulations in places, with the faintest indications of sub-obsolete 
costae, without a sign of the usual lateral row of punctures. 
Fpipleurce longitudinally impressed, abdomen with basal segments 
strongly striolate, apical segments closely and evidently punctate ; 
prosternum minutely punctate, in front convex with border raised 
and sub-tuberculate at: middle with some small transverse wrinkles 
behind this, the pro sternal process wide, parallel, its sides raised 
and channelled within, its apex bluntly rounded and slightly 
raised. The coxae, especially the four anterior, strongly punctured, 
tibiae straight, shortly bispinose, and tomentose at apex and for a 
short distance on inner margin. Under surface of head opaque, 
coarsely and closely punctate, the gula with two large foveae near 
middle, and finely transversely wrinkled near sides, teeth of sub^ 
mentum form large blunt prominent tumuli with apex simple.
