and. Species of Asiatic Longicorn Coleoptera. 47 



Dialeges pauper. (PI. XVI. fig. 7.) 



D. brunnea, sericeo-pilosa ; prothorace corrugata ; elytris 

 brunneo-velutinis, singulis plagis duabus sub-quadratus 

 fuscis. Borneo, Malacca. 



Head and protliorax greyish-brown, the latter with a darker or 

 nearly black figure resembling the letter W ; elytra velvety, light 

 brown with silvery reflections, and having each two oblique and 

 somewhat quadrate blotches of dark brown ; beneath brown, with 

 a whitish tomentum. 



Length 13 lines. 



Another of Mr. Wallace's Bornean insects closely resembles the 

 above in its colouring, and I have no doubt will prove to be the 

 female ; it is much smaller, less elongate, with small femora, an- 

 tennae shorter than the body, and altogether of a different cha- 

 racter, being perfectly glabrous and having the last six or seven 

 joints compressed and dilated at their extremities. 



Triammatus Chevrolati. 

 T. griseo-hirtus, nigro-variegatus ; elytris tuberculis nigris 

 nitidis, singulis plagis duabus nigro-brunneis ; subtus griseis, 

 lateribus capitis pectorisque albis. Borneo. 

 Hairy, greyish, variegated with black ; on the head three and 

 on the prothorax five indistinct black lines, a white line com- 

 mencing from under the eyes and gradually spreading out into a 

 patch on the mesothorax; elytra with numerous black tubercles 

 near the shoulders, and with coarse black punctures below, having 

 on each a well-defined brown patch, and below, but extending to 

 the margin, another and larger one, and between these a white 

 mark ; antennae with the fourth joint ($) brown, the fifth to the 

 last brown only at the ends. 

 Length 10 lines. 



Monohammus luridus. 



M. piceus, punctulatus, subtus albo-pilosus, elytris punctatis, 

 nigro-maculatis, pilis cinereis tectis. China Borealis. 



Head and thorax pitchy, minutely punctured, elytra covered 

 with ashy grey hairs, irregularly punctured and having on each 

 about twelve black spots ; body beneath covered with whitish 

 hairs, legs black, sparingly clothed with short whitish hairs ; an- 

 tennas black. 



Length 6 lines. 



This will come into the group with M. heryllinus, Hope, and 

 other allied species.
