New Species of Staph i/liin'rfac from Singapore. 85 



Staphylinini. 



37. Holisus parvus, n. sp. 



Depressed, linear, shining pitchy-brown; elytra obscure testa- 

 ceous ; the first three joints of the antennae fusco-testaceous ; legs 

 testaceous. 



Length 2-3 mm. 



Head large, a little longer than broad; temples parallel, the 

 posterior angles briefly rounded; eyes small; front truncate; 

 puricturation (for a small species) rather large superficial, feebly 

 umbilicate and rather close on the disc, temples almost impunc- 

 tate; pubescence Hue, sparing; mouth-parts pitchy-testaceous. 

 Antennae rather short, the 2nd and 3rd joints of equal length, the 

 4th as broad as long, the 5th slightly transverse, the following 

 joints gradually but slightly increasing in breadth, 11th oval. 

 Thorax narrower than the head, slightly transverse trapezoidal, 

 widest at anterior angles, narrowed in a straight line to the rounded 

 posterior angles; disc broadly but feebly impressed posteriorly; 

 puncturation very fine and not very close ; pubescence fine, less 

 sparing than on the head. Elytra slightly widened behind, a little 

 longer than broad, wider than the thorax, obscure testaceous more 

 or less infuscate about the scutellum and sides; puncturation and 

 pubescence very similar to that of the thorax. Abdomen a little 

 widened behind, the first three visible segments finely and moder- 

 ately closely, the following much more finely and sparingly, punc- 

 tured ; pubescence fine and sparing. 



Hub. Mandai. 



One specimen found under bark. 



38. Holisus cingulatus, n. sp. 



Pitchy-black, scarcely shining, the thorax, 2nd, 3rd, 4th, 8th 

 and posterior portion of the 7th abdominal segments and legs 

 reddish-testaceous ; first two joints of the antennae pitchy-testaceous. 

 Length 1'75 mm. 



A very small, narrow, parallel-sided insect, at once distinguished 

 from the preceding by the colour, smaller size, and shorter head. 

 Head large, massive, square, very slightly dilated at the temples, 

 which are long, with rounded posterior angles; disc broadly im- 

 pressed towards the front; puncturation rather fine, superficial and 

 moderately close, obsoletely umbilicate ; finely pubescent. Antennae 

 short, the 2nd joint shorter than the 1st, the 3rd much shorter than
