170 [July, 



Female : crown, pronotum and scutellum ivory-white, elytra lacteo- 

 liyaline, the membrane distinctly fumose. Length, 4 — 4*1. mm. 



Found by Mr. Oscar Whittaker very abundantly on willows at 

 Birkdale, 1911, and sent by him to me as T. salicicola. 



Typhlocyba distincta, n. sp. 



Male : upperside pale yellow, the colour more intense along the 

 veins of the corium ; the apex of the brachial area and the inner 

 apical angle of the supra-brachial area fuscous. Genital plates con- 

 cave, on the upperside before the apex a semi-circular notch, close to 

 the distal edge of which there is a triangular tooth ; styles with the 

 apical part bent at an acute angle to the remainder, the bent portion 

 widened for one half of its length then abruptly narrowed and acumi- 

 nate, the narrow part sub-equal in length to the broad ; the sedeagus 

 in the dorso-cephalad aspect has a triangular expansion towards the 

 apex which gives off two falcate connivent branches enclosing between 

 them a nearly circular space. 



The female of this species I have not seen. 



Length, 4*6 mm. Aspley Woods, Notts ; Prof. Carr. 



Typhlocyba bidentata, n. sp. 



Male : crown pronotum and scutellum ivory-white, corium canary- 

 yellow (chrome-yellow), membrane slightly fumose ; anterior and 

 intermediate tarsi fuscous, claws of the hind tarsi black. The sedeagus 

 ends in two short straight slightly divergent teeth. Length, 3 - 9 mm. 



Described from one male which I took off hazel at Colesborne on 

 October 15th, 1913. 



Typhlocyba carri, n. sp. 



Male: upperside canary-yellow (chrome-yellow), the colour very 

 intense along the veins of the corium, membrane scarcely fumose. 

 Genital style in the interno-lateral aspect ending in two dissimilar 

 divisions of which the upper one has its apical angles unequally 

 produced, the foremost one into a short comparatively blunt point and 

 the hinder one into a long sharp point ; the lower division is simply 

 acuminate. iEdeagus simple, as in T. douglasi. 



The female is similar in colour to the male. 



Length, 4 mm.

 male, Arnold, on oak, 13, VIII, 1913 ; Prof. Carr.
