LANGURIIDAE 359 



Mas, pedibus aulivi* perlongiSj femoribus tenuibus, intus, infra 

 medium dente acuto, et apicem propiore canaliculars et bicarinalh, 

 epitomate antice producto quasi rostrato. 



Hab. Sumatra, Liangagas, Soekaranda (Dohrn) ; Pangherang 

 Pisang, Si Rambé (Modigliani). 



The general colour of this insect is dark blackish-green above, 

 blood red beneath. The head is strongly and thickly punctured , 

 sometimes the front of the head is red, but in others it is me- 

 tallic green or nearly black. The thorax is half as long again 

 as wide, very convex and widest in the middle, much more 

 sparsely and obsoletely punctured than the head (but more 

 thickly punctured in the examples from Si Rambé) there are a 

 few scattered larger punctures towards the base and the striolae 

 are only represented by two deeper punctures. The elytra are 

 impressed with series of large squarish but irregularly shaped 

 punctures, their base is subdepressed , and the shoulders are 

 tumid, with a deep stria extending about a quarter of the length 

 of the elytra, and externally the marginal stria is very deeply 

 impressed under the shoulder. The antennae do not reach from 

 the eye beyond the middle of the thorax , the joints from the 

 third to the sixth are elongate and subequal, but the sixth and 

 seventh are triangularly slightly widened, the last four form a 

 rather lax club. 



The labial palpi are very small, scarcely visible except by 

 dissection, with a triangular apical joint; the maxillary palpi, 

 have their apical joint, as long as the basal part, quite subulate. 

 They are piceous in this species. The apex of the elytra have 

 three minute denticulations , besides the very minute external 

 mucro. These can only be seen under a good quarter-inch focus 

 lens. 



The examples I regard as female, have shorter legs and the 

 femora are thicker and not toothed nor grooved , the epistema 

 is not produced, nor in any way abnormal but is cut out in 

 an arc. 



The elytra in these examples have four or live denticulations 

 and a more distinct mucro.
