Pinkish-testaceous. Rostrum a little longer than its width at 

 the base. Thorax in the form of an equilateral triangle, the sides 

 moderately reflexed. Elytra widened a little below the shoulders, 

 rather ample before the apex, the sides rather strongly arcuate. 

 Legs black, except the base of the femora. $ . 



The foregoing description is taken from the original type in the 

 Banksian collection. The specimen is said to come from Siam. 



There are three specimens in the British-Museum collection from 

 Penang which agree very nearly with the Fabrician type, but the 

 colour is more yellow, the thorax less regularly triangular, and the 

 sides are not so suddenly reflexed. The male example is entirely 

 pale below, with the apex of the posterior tibiae and the tarsi 

 fuscous, and the apex of the elytra is black ; the two females have 

 the elytra entirely yellow, the metasternum and abdomen are more 

 or less dusky, and the legs are blackish, with the base of the femora 

 pale. 



Lycostomus placidus.

 nigris. Long. 4-7 lin., lat. l|-3^ lin.

Pale ochreous. The eyes, the fourth to the eleventh joints of the 

 antennae, the tibiae, and tarsi black. Thorax narrowed in front, the 

 disk somewhat shining. Elytra not much enlarged towards the 

 apex, the sides rather straight, the humeral ridge not very strong. 



This species differs from L. nigripes in being longer in the elytra, 

 which are also a little more parallel. The thorax varies immensely, 

 but appears to be always relatively longer than in L. nigripes, and 

 the disk is more shining. The legs are generally black, except at 

 the base of the femora, but a small example has the femora almost 

 entirely yellow. 



The specimens which have the apex of the elytra black are the 

 largest specimens, and have the thorax broader than in those with 

 unicolorous elytra ; but the largest unicolorous specimen and the 

 smallest example with black apex to the elytra agree so nearly in 

 size and form that I cannot consider them distinct species. The 

 specimens appear nearly all to have been taken together, and are 

 marked by Mr. Bowring 25|7|50. 



The variety with the black apex to the elytra much resembles 

 some specimens of L. analis, but may be distinguished by the rela- 

 tively longer elytra (which are not so much arcuate at the sides), 

 and by the form of the thorax, which is less trapeziform and less 

 silky than in analis.
