 Mousehold and Brundall, Norfolk; {Brlihjman), Bridge- 

 north; {Marshall) . 



M. equestris, Fah. — Differs from the above in the ? 

 by having the base and sometimes the whole of the 

 third abdominal segment red ; also in both sexes by the 

 more coarsely and closely puuctured mesonotum and 

 mesopleurae, in the narrower, parallel-sided, subcarinated 

 petiole of the abdomen, which in the S is much longer, and 

 in the pale tarsi and occasionally pale base and apex of the 

 tibiffi ; in the more strongly developed facial tubercle, and 

 in the ? by the longer transverse tubercle, and the slightly 

 reflexed anterior margin, of the clypeus. 



L. 7-9 mm. 



Apparently rare, but probably confused with the fol- 

 lowing. Southwold. Perth, N.B. 



M. bicolor, Fab. — Exceedingly like equestris in general 

 form and colour, but with the puncturation of the meso- 

 notum and especially of the mesopleurae much finer and 

 their surface more shining, the puncturation of the meso- 

 pleurae being scarcely noticeable ; the posterior impression 

 of the projjodeum is much less deep, and the petiole of the 

 abdomen in the ? is much longer, nai-rower, and more 

 distinctly carinate, but in the males of the two species the 

 petiole is very similar, although rather narrower and more 

 distinctly carinated in this. In the ? the anterior margin 

 of the clypeus is not reflexed. 



L. 7-9 mm. 



Abundant on the sandy commons about Woking and 

 Chobham. Smith says it furnishes its cells with a species 

 of Tettigonia, and records it from Hampstead ; Erith ; 

 Luccomb Chine ; Yarmouth ; Deal ; Dover and Yorkshire.
