 on the disk pale ochraceous, on the sides and beneath it is long, 

 dense and cinereous ; the tarsi bright ferruginous ; the anterior 

 coxae have a short acute spine. Abdomen : the base and sides 

 have a long pale pubescence, on the third and following seg- 

 ments it is short and fuscous, the apex incurved, the margin of 

 the sixth segment emargiuate in the middle and denticulate at 

 the sides, the seventh has a short acute spine in the middle. 



Since this species was described in the 'Zoologist,' a fine 

 series of examples have been obtained from France ; it is the 

 M. pyrina of St. Fargeau ; the sexes were captured at different

 them, and the probability of their being the same species was 

 suggested; such proves to be the case. The species is very 

 common near Paris.
