 Borneo. By Malcolm Cameron, m.b., r.n., f.e.s. 



PART II. 

 Aleocharin^ . 

 ousilusa brunnea d. sp. 



Shining; head black, thorax, elytra, and abdomen dark 

 pitchy-brown the posterior margins of the segments hghter. 

 Antennee black, the first two joints testaceous. Maxillary 

 palpi with 3rd joint black. Legs brown, tarsi testaceous. 

 Length 3.2 mm. 



A rather large, robust, dark brown species, much larger and 

 darker than the two species described by me from Singapore, 

 but similar anatomically. Head narrower than thorax, closely 

 covered with rather large umbilicate punctures. Antennae 

 rather long, gradually thickened towards apex, 2nd and 3rd 

 joints subequal, 4th to 7th longer than broad, gradually 

 decreasing in length and increasing in width, 8th to 10th 

 about as long as broad or slightly transverse, 11th long, conical. 

 a little longer than the two preceding together. Thorax 

 transverse, widest at the middle, the sides rounded and 

 narrowed in front, straighter behind, the posterior angles 

 obtuse, disc with a deep V-shaped impression in the posterioi- 

 half, arising from a deep fovea in front of the scutellum ; 

 sculpture granular, moderately fine, close, sparingly pubescent. 

 Elytra much broader than the thorax, convex, transverse, 

 closely covered with rather coarse pointed granules, much 

 coarser than those of the thorax. Abdomen a little narrowed 

 behind, the first three visible segments each with three 

 transverse rows of fine punctures, one at the base, another 

 behind the middle and other along the margin, otherwise 

 smooth and shining, the 5th finely and irregularly punctured, 

 the 6th finely but much more closely punctured.
