DESCRIPTION OF A NEW BRITISH TYPHLOCYBA. 

 BT JAMES EDWARBS. 



Ttphloctba Douglasi, n. sp. 



$ deep yellow, inclining to orange ; ? paler, with the elytra milk-white ; apex 

 of elytra broadly fuscous in both sexes. 



Crown somewhat obtuse. Pronotum 

 nearly one-third longer than the crown. 

 Elytra in S deep yellow inclining to orange, 

 in $ milk-white, the apex broadly fuscous 

 in both sexes, the limits of the colour 

 sharply defined and extending inwardly 

 from the base of the first or costal cell to 

 a point about the apical seventh of the 

 claval suture. Nerves of the membrane 

 deep yellow in ^ , paler in $ . Wings 

 opaque white, nerves distinctly yellow. Length, 1^ line. Expanse, 3 Imes. 



This very distinct species, whicli I liave great pleasure in naming 

 in honour of my esteemed friend Mr. Douglas, is remarkable for the 

 great development of the genital appendages in the male, these being 

 nearly twice as large in proportion to the size of the insect as in any 

 other species with which I am acquainted. The accompanying figures 

 of the inner genital process of T. Douglasi (1), T. roscd (2), and T. 

 cratcBgi (3) will serve to show the excessive development of those 

 parts in the first named species. The species is scarcely likely to be 

 confounded with any other, except perhaps that the female might be 

 passed over as a variety of rosce, with which species it agrees in the 

 neuration of the wings. 



Beaten from fir in March and blackthorn in September, in two 

 localities near Norwich.
