touching the upper margin only ; the fifth is very long, attached 

 to the upper margin, and, at half its length, taking a bend towards 

 the body of the insect ; the sixth resembles the fourth, and is 

 nearly apical. 



Taken by Mr. Walker at Southgate. I have seen but one 

 specimen of this very beautiful insect. 



Natural Order. — Muscites, ined.

Trix. scutellata. Nigra; mesoihoracis scutello, pcdibusque 

 ferrugine'is. 



Black, slightly clouded and variegated with grey : head, above, 

 black ; below, including the front and antennae, ferruginous : 

 mesothoracic scutellum, and legs, also ferruginous : the remainder 

 of the trunk black : wings, exteriorly, smoky ; interiorly, the 

 upper portion stained with saffron. (Breadth 1 inch.) 



Taken in Epping Forest by Mr. Doubleday.

Cat. nubifer. Fuscvs; prothorace medio fiisco, laterihus 

 ferriigineis. 



Head black : antennae, with the three basal joints, pale ferruginous, 

 and shining ; then, to the apex, fuscous, with the exception of 

 the apical joint, which is paler : prothorax ferruginous, bearing a 

 fuscous cloud centrally, which extends to none of its margins : 

 mesothorax, ferruginous : elytra fuscous : the latter, at the shoulders, 

 more or less ferruginous, in some specimens, which are possibly 

 immature, the latter colour pervades nearly the whole of the 

 elytra: legs fusco-ferruginous, (Length \\ lin,) 



Taken at Halifax ; and is apparently very distinct from 

 any species described as British.
