86 Mr. James Edwards' Synopsis of 



The female of this species is abundant at the roots of 

 grass in the autumn, and varies much in colour, some 

 examples being nearly black, in which case the pale disc 

 of the pronotum and scutellum and the inner marginal 

 nerve of the elytra are very conspicuous. Males are 

 difficult to meet with in company with females, but they 

 occur more freely a little earlier in the season. The 

 nymph of this species is the Achorotile hivittata, Boh., of 

 Fieber and Puton's catalogues.

Similar in size and appearance to the last named, but the pale 

 ground colour of the upper side is dirty white, inclining to bluish 

 grey, and the dark stripe on the sides of the pronotum and scutellum 

 is rarely so decided as in that species. Styles (PI. II., fig. 12), 

 viewed from behind, somewhat cleaver-shaped, wide, flat, black, 

 truncate at the apex, their inner margin faintly concave on its 

 lower half, with a feeble obtuse tooth just above the middle, and 

 another, similar, at the apex, outer margin simple. 



Dunston, near Norwich, at roots of coarse grass, 

 September and October ; local. The nymph of this 

 species cannot be distinguished from that of the last, 

 except by the evidence afforded by its occurrence in 

 company with the adult form.
