and Species of Asiatic Longicorn Coleoptera. 49 



The peculiar antennas of the male, and the absence of the naked 

 shining ' tubercles on the elytra, so general in the Monohammi, 

 appear to point this out as the type of a new genus. 



Monohammus diophthalmus. 



M. brevis, piceus, pilis brevibus cinereo-albis tectus ; elytris 

 singulis basi sub-ocellatis, maculaque magna lateralibrunneis ; 

 antennis mediocris sub-ciliatis. China Borealis. 



Pitchy, covered with short greyish white hairs ; sides of head 

 and thorax brown, having a broad stripe, extending from between 

 the antennae to the scutellum, greyish white ; elytra with a small 

 brown sub-ocellate spot at the base, having five or six black 

 shining tubercles in the centre and several more on the shoulder, 

 a large brown somewhat triangular spot at the side, beyond the 

 middle and spreading out at the margin ; antennae moderate, sub- 

 ciliated beneath ; legs, particularly the tarsi, covered with short 

 whitish hairs. 



Length 12 lines. 



This species is near M. crucifer, F., from Ceylon, 



Monohammus ? angustus. 



M. ? elongatus, pilosus, fulvo-brunneus ; prothorace tuberculato ; 

 elytris punctatis singulis plagi obliqui laterali fusca; antennis 

 longis fuscis, pedibus brevibus fuscis. China Borealis. 



Narrow, elongate, and covered with yellowish brown hairs ; 

 prothorax rather short, with numerous black shining tubercles, 

 the lateral spine acute ; elytra punctate, with an oblique dark 

 brown patch, not meeting at the suture, pointing and becoming 

 less determinate towards the apex, above this patch is a somewhat 

 yellowish mark and below it another ; legs brown and rather short, 

 particularly the posterior pair ; antennae rather long, brown, the 

 joints generally darker towards their apices. 



Length 9 lines. 



In its lengthened form and short legs this insect assumes a 

 different /oc/e* from others of the genus Monohammus. 



Golsinda tessellata. 

 G. nigra, densissime pilosa ; elytris albo-maculatis, profunde 



punctatis ; antennis pedibusque annulatis. Borneo. 



Dull brownish black, marked everywhere above with round or 



oval distinct or occasionally confluent spots, but more obscurely
