punctured. Antennae .slender, all the joints distinctly longer than 

 broad, except the 10th which is but slightly elongate. Thorax 

 broader than the head, transverse, widest at the junction of the 

 anterior and second fourths, from thence strongly contracted pos- 

 teriorly in an almost straight line; disc with distinct transverse 

 impression before the base and in front of this the surface is so 

 impressed as to form an M-shaped elevation; on either side also are 

 two short, oblique impressions ; puncturation similar to that of 

 the head. Elytra about one-third longer than the thorax, scarcely 

 transverse; disc on either side of the suture for the anterior two- 

 thirds with a longitudinal impression; puncturation similar to that 

 of the thorax. Abdomen not widened behind, exceedingly finely 

 and moderately closely punctured and pubescent. 



Hab. Bukit Timah, Mandai and Sembawang, in debris, 

 on the banks of the jungle streams. Appears to be a 

 common insect. 



6. Trogophloeus (Taenosoma) halophiloides, n. sp. 



Nearly opaque, black; head and thorax densely shagreened, 

 impunctate ; first six joints of the antennae and legs pitchy-testace- 

 ous. Length l - 3 mm. 



Very similar to the Palaearctic T. halophilus, Kies., from which 

 it differs in the following respects : the- shagreenirig and pubescence 

 of the head and thorax are coarser, the antennae much stouter, the 

 sides of the thorax more evenly rounded, the elytra much shorter, 

 slightly widened behind and a little more strongly punctured. Head 

 slightly narrower than the thorax, constricted behind, the temples 

 shorter than the diameter of the cats, which arc rather large; the 

 titiiit longitudinally impressed on either side; the vertex with a 

 small, smooth, shining plaque, the rest of the surface densely 

 shagreened, without visible puncturation ; pubescence rather coarse, 

 griseous. Antennae with the 2nd joint shorter than the 1st, the 

 3rd about half as long as the 2nd, the 4th to the 7th square, 

 the 8th to 10th transverse, the 9th to 11th larger than the 

 preceding. 



Thorax transverse, widest at the junction of the anterior and 

 middle thirds, the side evenly rounded and converging both ante- 

 riorly and posteriorly, but more strongly so posteriorly; the disc 

 with four obsolete impressions; sculpture and pubescence as on 

 the head. Elytra a little longei than the thorax, transverse, 

 slightly widened behind; with puncturation and pubescence much 

 as in T. halophilus. Abdomen slight I \ widened behind, very finely
