Neiv Species of Slaqjhylimdae from Singa'porc. 283 



HoLisoMiMUS, n. gen. 



Antennae distant, situated on the front margin of tlae head, 

 just external to the level of the inner margin of the mandibles. 

 Eyes small and flat. Mandibles long, stout, prominent, the right 

 pointed at the apex and with a tooth at the middle of the inner 

 margin, the left thickened at the apex, which is excavated internally. 

 Maxillary palpi 4-jointed, the 1st joint small, the 2nd elongate, 

 lightly cm-ved and slightly thickened towards the apex, the 3rd 

 a little longer than the 2nd, the 4th subulate, about half as long as 

 the 3rd. Outer lobe of the maxilla elongate, truncate at the apex, 

 wiiich is ciliate; inner lobe narrower than the outer, uncinate at the 

 apex, strongly pectinate along the inner margin. Tongue broad 

 membranous, gradually narrowed towards the apex, which is 

 divided for a short distance into two bluntly pointed lobes. Labial 

 palpi 2-jointed, the 1st joint elongate, cylindrical, the 2nd narrower 

 and a little shorter than the 1st, the apex rounded. Mentum (pars 

 antica) short, transvei'se, broadly emarginate in front. Temples 

 not bordered below. Gular sutures coalescing posteriorly. Pro- 

 sternum large, triangular, obtusely pointed behind. Mcsosternal 

 process very short, scarcely extending between the intermediate 

 coxae, which arc contiguous. Femora stout. Tarsal formula 4, 4, 5 ; 

 the anterior and intermediate pairs with the first three joints short 

 and subequal, the 4th rather longer than the three preceding 

 together; the posterior pair with the first four joints short and 

 subequal, the 5th about as long as the three preceding together. 



This genus is founded on the species described Qoc. cit.) 

 as Holisvs panms and H. cingvlahis. 



46 (a). Conosoma malayanum, n. sp. 



Black, moderately shining, the posterior border of the thorax 

 narrowly, the posteroexternal angles more broadly rufescent; 

 elytra with small obscure reddish spot in the middle of basal margin. 

 Antennae filiform, the first three and the last joints clear testaceous. 

 Length (extended) 5'3 mm. 



In build identical with C. pubescens Gr., but differs in the colora- 

 tion, ]nuch longer antennae, much shorter elytra and more strongly 

 setose abdomen. Antennae filiform, all the joints longer than broad, 

 the 11th longer than the 10th. Thorax black, very finely and 

 moderately closely punctured and pubescent, the postero-external 

 angles and posterior margin rufescent but not sharply so. Eh-tra 

 scarcely as long as the thorax, transverse, as finely but less closely 

 punctured than in C. jnihescevs, finely pubescent, the base with a
