The elytra are striate but not punctate. The ridges between 

 the grooves are narrowed behind, all extending right back into the 

 posterior angles of their respective elytra. 



The prosternum is bluntly but very strongly transversely keeled 

 in front of the anterior coxae; it is longitudinally grooved in the 

 middle between them. On either side of the groove it is somewhat 

 angular above the abrupt posterior declivity. Both prosternum 

 and mesosternuni are strongly punctured. The metasternum is 

 unpunctured, but is longitudinally grooved in the middle line. 



The abdominal sterna are somewhat sparsely punctured or 

 finely and indistinctly rugose. 



The antennae are ii-jointed. The first joint is pear-shaped 

 and about as long as the third joint, which is slender and almost 

 cylindrical. The second joint is only about as long as wide. The 

 fourth, fifth and sixth joints are slender and are about equal in 

 length; any two of them would be together about equal to the 

 second and third joints together. The remaining joints are of 

 about the same length as these, but are thicker distally. 



The legs are all slender The femora and tibiae are uniformly 

 black ; the tarsi are somewhat reddish, 



Dietysus nodicornis, n. sp. 

 (Plate xliv, fig. 15.) 



One specimen was found under bark at Rotung, 1400 ft., in 

 the Abor Country, 23-xii-ii. 



Very like the preceding in general appearance, but much 

 larger. Its antennae, too, are stouter and moniliform. Length 

 i4"3 mm. 



The head resembles that of D. fiUcoYnis, but the band between 

 the clypeus and labrum is black, not brown, and the suture between 

 the clypeus and frons is clearly defined. Both head and pronotum 

 are very distinctly punctured. The latter resembles that of D. 

 filicornis in form. 



The scutelhim and the plates of the lower surface also resemble 

 those of D. filicornis. 



The elytra are somewhat more parallel-sided in front than in 

 that species. They are similarly grooved, but the ridges between 

 the grooves appear slightly more convex. 



The first joint of the antenna resembles that of D. filicornis; 

 the second is somewhat stouter than in that species ; the third is 

 somewhat abruptly swollen at the distal end. The fourth joint is 

 about half as long as the third; its proximal end is somewhat 

 thinner and its distal end somewhat thicker than are the corres- 

 ponding ends of the third joint. The fifth joint resembles the 

 fourth, but is only about two-thirds of its size. The sixth joint is 

 about equal to the fourth in length, but is almost cylindrical in its 

 proximal half, swelling out to resemble the fifth joint distally. 

 The next four joints are about equally long, but enlarge gradually 

 from base to apex. The terminal joint is similar, but is obliquely
