Neiv Species of Slaph/linidae from Singapore. 225 



elongate, gi-adually thickened towards the apex, 3rd shghtly longer 

 and stouter than the 2nd, 4th subulate fully half as long as the 3rd. 

 Inner lobe of the maxilla narrow, lightly incurved and pointed at 

 the apex, pectinate internally; outer lobe broader than the inner, 

 narrowed and pointed at the apex which is ciliate. Tongue narrow 

 and elongate, nearly extending to the level of the apex of the first 

 joint of the labial palpi, bifid at the extremity. Paraglossae distinct, 

 ciliate, not extending beyond the apex of the tongue. Labial palpi 

 3-jointed, the 1st joint moderately long, cylindrical, the 2nd narrower 

 and about half as long as the 1st, the 3rd narrower and about twice 

 as long as the 2nd, cylindrical. Gular sutures distant, slightly 

 divergent behind. Temples bordered below. Prosternum broadly 

 rounded behind. Mesosternal process narrow and pointed, extending 

 two-thirds along the coxae, which are narrowly separated. Meta- 

 sternal process rounded at the apex. Tarsal formula 4, 4, 5. The 

 first pair of tarsi with the first three joints short and subequal, the 

 4th longer than the three preceding together; the second pair 

 with the first two joints short and subequal, the 3rd a little longer, 

 the 4tli longer than the three preceding together; the third pair 

 with the 1st joint moderately elongate, the 2nd, 3rd and 4th gradu- 

 ally decreasing in length, the 5th longer than the two preceding 

 together. Elytra sinuate internal to the postero- external angle. 

 Superficially the species on which this genus is founded might be 

 taken for an Atheta of the nigritula group. 



82. Pseudatheta elegans, u. sp. 



Rufo-testaceous, moderately shining, the elytra (except the 

 base), the posterior half of the fifth and the whole of the sixth 

 abdominal segments black; the first three joints of the antennae 

 and the legs testaceous. Length 1-75 mm. 



Head transversely orbicular, darker in colour than the thorax; 

 eyes moderate; very finely and indistinctly punctured, finely 

 pubescent. Antennae moderate, the first three joints subequal, 

 the 4th to the 10th transverse, the penultimate two and a half times 

 as broad as long, the 11th large, oblong-oval, longer than the two 

 preceding together. Thorax transverse one and a half times 

 broader than long, widest just before the middle, the sides bordered, 

 narrowed and rounded anteriorly, converging posteriorly in a nearly 

 straight line to the obtuse posterior angles, the base bordered and 

 feebly sinuate on either side; puncturation fine and moderately 

 close, finely pubescent. Scutellum ferruginous, transverse, very 

 finely punctured. Elytra transverse a little longer and broader 

 than the thorax, black, the base more or less rufo-testaceous, very
