49. Macroscytus expansus, Signoret. 

 A. S. E. F. (6 s.), ii, p. 479, t. 14, f. 138 (1882). 



Body oblong, oval, of a blackish-brown : rostrum, base and tip of 

 the antennoe and the feet of a lighter colour : tarsi, yellow : hemelytra 

 light brown ; fiLcly punctured on the posterior disc of the pronotum, 

 the scutellum and the hemelytra. Tylus on a level with the juga which 

 have six hairs ; vertex weakly furrowed : third joint of the antennae 

 shorter than the second : pronotum with 10 — 11 hairs on the lateral 

 margins ; behind the emargination the points are very obsolete : scutel- 

 lum smooth at the base, sparingly punctured on the disc, tip angular : 

 membrane hyaline ; abdomen smooth in the middle, with very fine small 

 strioe, on the sides : the mesosternal dull plate (plaque mate) finely 

 striated, rounded at anterior angle, separated from the mesosternal 

 groove by a broad glossy band which is punctured and furnished with 

 small striae, that of the metasternum is finely striated and punctured : 

 the ostiolar canal ends in a two-lobed part of which the external lobe is 

 broadly dilated and there is a broad rounded valve in the indentation. 

 Possibly only a local variety of M. brunneus, Fabr., from which it differs 

 in its appearance but especially in the form of the tip of the ostiolar 

 canal which is here much dilated and is confused with the thickened fold 

 of the mesosternal groove (Sign.). Long, 7 ; broad, 4 mill. 



Reported from Bombay. 



Genus Geotomus, Mulsant & Rey. 

 Pun, France, p. 34 (1866) ; Sign. A. S. E. F. (6 s.), iii, p. 33 (1883). 



Differs from Cydnus in the absence of small spines on the head. 

 The rostrum is short, usually not extending beyond the intermediate 

 trochanters which distinguishes it from Gampsotes : the anterior border 

 of the pronotum is not margined which separates it from Fangceus : 

 the absence of the tumidity on the lateral angles of the disc of the 

 pronotum which conceals the real angle as in Macroscytus and the 

 posterior femora being spinose at the tip give sufficient characters for 

 distinguishing it. Moreover the ostiolar canal is terminated by a reni- 

 form or cornet-shaped lobe (Sign.).
