the propleura densely clothed with brownish pubescence, and the base 

 of each elytron set with transverse asperities ; the first-mentioned 

 character may be peculiar to the male (?). The short ante-coxal portion 

 of the prosternum is very little produced between the coxae. The 

 basal joint of the antennae is received in repose in the broad genal 

 sulcus. 



2. — Dapsiloderiis mdniaceus, n. sp. 



Very elongate, sub-cylindi*ical ; black, the head on each side, the prothorax 

 (a narrow black median stripe excepted), and the elytra carmine-red, the upper 

 surface thickly clothed with fine, similarly-coloured, velvety pubescence, the 

 clothing of the under surface blackish-brown ; very densely, minutely, re- 

 ticulato-punctulate. Antennae long, joint 2 short, small, 3-10 very broad, 

 serrate, strongly compressed, 6-10 becoming gradually narrower, 11 about half 

 the width of 10, appendiculate. Prothorax transverse, uneven, the sides 

 rounded anteriorly and sub-parallel at the base, the latter bisinuate, the hind 

 angles directed backward ; the disc obsoletely canaliculate, and transversely 

 nodose and sinuato-excavate on each side at about the middle, the excavation 

 extending downward to the basal margin, the base also with a median fovea. 

 Scutellura large. Elytra very long, quadri-costate, the third costa becoming 

 obsolete towards the base, the humeri and the first costa transversely asperate 

 for some distance below the base. Anterior tarsi slightly widened. Fifth 

 ventral segment sub-truncate and feebly excavate in the middle at the apex. 

 Length 13, breadth, 3 mm. (<?.?) 



Hab.: Tenassbrim, Tavoy (Doherty). 



One specimen, somewhat immature. This insect, at first sight, 

 looks like an almost immaculate variety of D. ferminalis, from which, 

 however, it is readily separated by the bisinuate base of the prothorax, 

 the sides of which are also less rounded. The uneven surface of the 

 prothorax may be partly due to immaturity, but this is hardly likely 

 to be the case. The transverse asperities at the base of the elytra 

 are also differently placed, the ante-coxal portion of the prosternum 

 is more produced in the middle behind ; and the maxillary palpi are 

 shorter than in D. terminalis. The genal sulci are broad and shining 

 in both species. 



Dapsiloderinus n.'gen. 



Antennae with joint 2 minute, 3-11 greatly dilated, compressed, and serrate, 

 11 appendiculate ; maxillary palpi broad, serrate, joint 2 triangular, 3 strongly 

 transverse, 4 cultriform, longer in S than in 9 ; head vertical, rather small ; 

 eyes transverse, emarginate ; prothorax margined at the sides posteriorly ; 

 scutellum triangular, depressed, almost covere I by the basal lobe of the pro- 

 thorax; elytra very elongate, parallel, confusedly punctured, the suture
