covered with distinct punctures which become smaller 

 towards the end ; the apices are obliquely truncate , the 

 sutural angle is rounded, the outer angle produced into 

 a point. Body beneath , legs and antennae impunctate. 



Hah. Borneo occ. : Sambas. — One female, captured 

 and presented to the Leyden Museum by Dr. J. Bosscha. 



Obs. The described specimen is remarkable for its

Pelargoderus marginipennis^ n. sp. 9« 



A very distinct species, easily recognizable by the gla- 

 brous elytra which are surrounded (except at the base) with 

 a dense yellowish white pubescence. 



Length 29 mm. — Black; the head glabrous , variegated 

 on the face , cheeks and vertex with small spots of a dense 

 yellowish white pubescence; a similar spot is present on 

 the base of the mandibles ; antennae , thorax , legs and 

 abdomen covered with an extremely short and loose grey 

 pubescence ; on the apical portion of the antenual joints 

 this pubescence is infuscate; the scutellum is covered with 

 a dense yellowish white pubescence , but shows a glabrous 

 line along the middle of the basal half; the elytra are 

 glabrous and shining, except along their sutural and 

 lateral margins where a dense yellowish white pubescence 

 is present. 



The head shows a few deeply impressed and irregularly 

 spread punctures on the face and cheeks (those on the 

 face are larger), and a deeply impressed groove along the 

 middle of the vertex. The scape of the antennae is finely 

 punctured. The prothorax is slightly corrugated and spa- 

 ringly punctured above and shows scarcely any trace of a 

 lateral tooth. The scutellum is parallel -sided , and broadly 

 rounded behind. The elytra are granulate at the base , the 

 granules followed up by large, deeply impressed punctures 

 which, however, become evanescent towards the end; the
