constriction, and its cylindrical form gives them a peculiar look, 

 not unlike that of Tillicera (javanica and cleroides^ Gorham), 

 and distinguishes them from Orthrius^, as does the distinctly cut 

 out eyes, and punctured and rasp-like granulations of the elytra.

The head is of the width of the thorax, with strong and 

 prominent jaws which are pitchy black, coarsely punctured at 

 their bases externally; the crown of the head is shining with 

 sparse punctures, which are however thicker in front, and with 

 wrinkled sculpture behind the eyes. The thorax is longer than 

 wide, with a very little impressed constriction in front, the 

 posterior constriction cuts off rather more of the base, than in 

 Orthrius (0. cylindricus) and appears as a strong submarginai 

 line, recurving up the sides; the lateral lobes are little promi- 

 nent, but marked by impressed lines ; the surface between the 

 constrictions is confluently rugosely punctate. The sculpture of 

 the elytra varies a little, in one specimen the punctures are 

 distinct, deep holes, with their edges becoming rasp-like gra- 

 nulations in the basal black or pitchy part, and becoming 

 obsolete after the first yellow fascia, with the interstices slightly 

 raised in the posterior half, in others, as the one in my collection 

 from Laos, the elytra are crenate-striate , with the punctures 

 confused, except at the base and sides. The dark basal portion 

 has usually a pale pitchy yellow spot on each elytron. Legs 

 rusty-yellow, knees only just touched with darker brown. The 

 Burmah examples are of the larger size. The Laos specimen 

 wants the pale spot, and in this respect it agrees with a single 

 specimen from Bhamo, which from its shorter antennae, with 

 the joints succeeding the third and especially the terminal joint 

 much shorter, I think to be the female. This example is also
