scattered iipri<,'lit hairs, and the antennal clulj more strongly pro- 

 nounced. From the latter it may be distinguished by its short rostrum 

 and the incompletely developed marginal line of the thoi-ax. 



The type is the species, redescribed below, that I take to be 

 Laiilh((nus ronueri Pic. 



Lissodema laevipenne Mars., which must also be included in this 

 genus is more elongate than P. rouyerl and has the thorax less trans- 

 verse and more strongly and more evenly punctured on the disc, the 

 elytra distinctly though finely punctate, etc. ^

The following is an amplified description of an insect that I have 

 little hesitation in referring to this species ; the antennal structure differs 

 remarkabl}^ from that of the Central and South American genus Lanchanus 

 Champ. If I am in error in assuming this identity, the present species 

 may be known as P. hryanti, sp. n. 



Ovate, nitid, .sparsely setose, head and thorax brassy-black, el3'tra piceous, 

 e.'icli witli a large fulvous spot behind the shoulder and another towards the 

 apex. Ilejid moderately strongly, not very densely, punctate; antennal joints 

 1-3 testaceous, 4-8 piceous, 9-11 black. Thorax more strongly but irregularly 

 punctate, witli a gmup of very large punctures on each side of the disc. Elytra 

 snitioth and nitid, with scattered erect golden hairs. Underside and femora 

 piceous, tibiae and tarsi paler. 



Length 1| to 3 mm. 



Hah. BoiiNEO (S.E. : German Mission), Mount Matang,W. Sarawak 

 (G. E. Bryant) ; Penang {G. E. Bryant). Under loose bark of felled 



trees. 



The elytral spots vary considerably in extent, the two subapical 

 ones occupying almost half the elytra in one of the two S2)ecimens from 

 S.P]. Borneo ; in others these spots are so obscure as to be hardly visible. 

 L. rouyeri was described from Java. 



This species bears a very close resemblance to Flatysalpinyus alho- 

 nofntus Pic, from the Kei Isls., and to Lanthanus varieqatus Champ., 

 fi-om Central America. From the former it differs in its short rostrum, 

 fi'om tlie latter in its antennal structure (see table of genera).

Head sunk in prothorax almost to the eyes ; rostrum long, antennae 

 inserted in lateral grooves towards the base ; basal joint of latter inflated, 

 2ud almost as long as 3rd, 4th to 8th successively shorter, last three joints
