New Species of Stapliylinidae from Singapore. 79 



setae; the lines on the disc are so curved as to resemble the outline 

 of a lyre. Scutellum shining, impunctate. Elytra about as long 

 as the thorax, a little longer than broad, not quite so dull as the 

 thorax, and more obscurely coloured; densely and closely, but less 

 finely punctured than the thorax. Abdomen pretty closely and 

 moderately coarsely punctured, especially at the bases of the 

 segments, more finely punctured posteriorly; pubescence rather 

 long, but not dense ; anal styles testaceous, slightly curved upwards. 

 c?. Seventh ventral segment with a deep, narrow, triangular 

 excision in the posterior margin, the sides of which are finely 

 bordered.

30. Calliderma nitens, n. sp. 



Rufous, shining, elytra black, less polished; legs, palpi, and 

 antennae testaceous, the apex of the 1st, and the whole of the 2nd, 

 3rd and 4th joints infuscate. Length 5 mm. 



A very shining insect, with glabrous, impunctate thorax, and 

 dark elytra, except for the extreme base, which is shining and 

 rufescent. Head shorter than in ('. rufum, the temples longer, 

 straighter and converging, the impression on the vertex triangular; 

 puncturation sparing, obsolete and setiferous, the antennal tuber- 

 osities and the sides of the head in front of the eyes with coriaceous 

 ground-sculpture ; the front, the space between the antennal 

 tubercles, and the immediate vicinity of the median sulcus and the 

 temples, without ground-sculpture. Antennae longer and more 

 slender than in ('. rufum, with the 1st joint about equal to the five 

 following joints together, the 2nd a little shorter than the 3rd, 

 the 3rd to the 9th all distinctly longer than broad, gradually de- 

 creasing in length, the 10th as long as broad, the 11th short, oval. 

 Thorax narrower than in ('. rufum, the sides more sharply angu- 

 late and without trace of puncturation or ground-sculpture ; the 

 disc with a sulcate carina extending from the base almost to the 

 level of the widest part, where it opens out into a longitudinal 

 impression that extends almost to the anterior margin, and on either 

 side with a raised sinuate line, which in. front turns inwards to join 

 its fellow limiting the median impression and separating it from the 

 anterior margin, and behind likewise unites with its fellow and the 

 median carina; sides strongly impressed behind the anterior angles; 

 the lyre-shaped pattern formed by the raised lines not so obvious 

 as in some of the other species of the genus, this being due to the 

 uniformly shining surface. Scutellum red, impunctate. Elytra
