scape straw. Stigma and nervures dirty white ; the 

 latter rather the darker. 



The female differs from the male in having the lower 

 part of the face dusky, and the thorax nearly entirely 

 dark ; aculeus about as long as the 1st segment. In this 

 species, as well as acicidatiis, the aciculations are not so 

 decided as in complanatus. Length 3 mm. 



Bred by Mr. G. C. Bignell from Macrocentrus thora- 

 cicus, out of Nocttia triangulum, and out of X. rhizo- 

 litha. 



The colour of the stigma easily separates this from 

 M. aciculatus.

I have taken two males at the end of May and middle 

 of June close to Norwich. 



TRYPHONIDiE. 

 Mesoleptus antilope, Gr. 



This, Brischke says, is a Catoglyptus, and perhaps 

 equal to C. pulchricorms, Holm., which latter has been 

 taken by Dr. Capron, and previously recorded. 



Mesoleptus leucostomus, Gr. 

 This he places in the genus Trematopygas. 



Mesoleptus vulneratus, Zett. 



Tryplion vulneratus, Zett., Ins. Lapp. 387, 18, <? . 

 Mesoleptus vulneratus, Holm., Mon. Try. Suec. 102,

I have received both sexes of this species from Mr. 

 Cameron ; they have " Thornhill " attached to them, so 

 were probably captured by Dr. Sharp. 



Mesoleptus similis, Brischke. 



Brischke, D. Ichn. d. Prov. W. u. 0. Preus. 96, <? , $ . 



A male of this species was taken last year by Mr. G. 

 C. Bignell in the neighbourhood of Plymouth.
