422 Mr. A. White on some new Insects from China. 



LIV. — Desa-iptions of some new species of Coleoptei-a and Ho- 

 moptera from China. By Adam White, Esq., M.E.S. Lond. 

 and France, 



In a small collection of insects sent to the British Museum by- 

 John Bowring, Esq., and collected by him in the island of Hong 

 Kong, occur the species described below. In a letter Mr. Bow- 

 ring remarks : " I have been much surprised at finding that there 

 is so great a difference between the insects on this island and 

 those on Macao Peninsula, a difference for which it is difficult to 

 account, in places so close to each other (Macao is only 40 miles 

 off) . The climate here is certainly damper, and the character of the 

 land much more rocky and clayey. Macao is chiefly a sandy soil." 



Cicindela posticalis. — A species nearly allied to Cic. analis, 

 Fabr., from which it may be distinguished by its thorax being 

 more globular ; the elytra want the depression about the middle, 

 which gives to analis a velvety-like mark on that part ; in this 

 the terminal segments of the abdomen, instead of being rufous, 

 are of a deep blackish blue ; in other respects it resembles C. 

 analis, Fabr., of which it may prove a local variety. Length 6| 

 lines.

Tricondyla pmlchripes. — Of a deep black, the elytra with a 

 greenish bronzed tinge. Head smooth, the peduncles from which 

 the eyes project with several fine striaj. Thorax considerably 

 elongated, with a faint impressed line 

 down the middle and an arched line on 

 each side ; between the arched lines are 

 many fine but very distinct slightly waved 

 transverse lines which run into each other; 

 the sides of the thorax are cpiite smooth. 

 Elytra punctm'ed at the end, at the base 

 rugose, and about the middle transversely 

 but irregularly lincated, with deep dots in 

 the lines, which give these parts the ap- 

 pearance of being scaled. Legs, especially 

 the femora which are more lightly co- 

 loured, with a fine pui'plish tinge. Length 

 8 lines.

Helluo {Acanthogenius) asteriscus. — Head, thorax and elytra 

 deeply punctured, rather hairy, and with the legs of an obscure 

 pitchy black ; the large labrum is smooth and polished. Elytra 

 with nine striae, the interval between the eighth and ninth having 

 a row of large papillated points ; third, fourth^ fifth, skth and
