A subparallel, shininj^, and rather narrow species, with tlie front parts and 

 the whole ixndcrside red, or with the centre of the hitter more or less pitchy 

 red; antennie with a broad club, the seventh joint also beinj^ dilated and 

 triangular, although much smaller than the eighth ; the prothorax is almost 

 square, witli the sides gradually and only slightly narrowed to base, the disc 

 moderately convex and sparingly furnished with diffuse pixnctures, and the base 

 depressed and with a short and very distinct broad impressed stria on each side ; 

 scutelliun red ; elytra cyaneous, with distinct and fairly regular rows of 

 punctures, apices jointly truncate ; legs black, except bases of femora which are 

 pitchy ; coxae pitchy-red ; coxal lines long, ijarallel, slightly divergent at 

 apex. Length 7 mm. 



Two specimens labelled " Batu Soufj Mount and Apoh River, 

 Hose Coll., Borneo." 



This species comes somewhat near to Languria nitidior, Crotch, 

 from Penaug, but the prothorax is quite differently shaped, and it may 

 further be distinguished by the dark legs (in nifidior these are mostly 

 red) , and the darker colour of the duller elytra, and also by the smaller 

 size of the seventh joint of the antenna).

A CONTRIBUTION TOWARDS THE LIFE-HISTORY OF 

 BEBYTUS CL AVI PES, F. 



BY E. A. BUTLER, B.A.. 15.Si., F.E.S. 



On May 25th in the present year, I had the good fortune to 

 find three ^ (^ and four $ ? of the Hemipteron Beryfvs rlavijjes, F., 

 at the I'oots of grass on a wayside Imnk at Royston, Herts. The ? ? 

 were very gravid, and as this species is one of the rarest of our British 

 Berytidfe, having been recorded hitherto from six counties only, I was 

 very anxious to secure some eggs. I accordingly enclosed the 5' ? in 

 a box with some grass stems and leaves, and added one ^ . This 

 immediately paired with the smallest of the ? ? , and they remained 

 coupled for three days. Although the insects were found amongst the 

 roots of the gi-ass, there were, of course, many other plants mingled 

 with this, and I could not be sure that the grass was really their food-
