220 APPENDIX TO VOL. I. 



Sometimes the clypeus is white, and in one specimen 

 (a (J ) the flagellum is reddish. 



From the two British species with oblong eyes the 

 red-belted abdomen separates it ; from the other red- 

 banded species the oblong eyes afford a good distinc- 

 tion, this being the only red-banded species with eyes 

 of this form. 



Taken by Mr. Edward Saunders at Chobham. It is 

 not, I believe, a common species, and has been only 

 recorded from Sweden, Germany, and France.

BLENNOCAMPA MELANOOEPHALA (p. 245). 



As the tf of JB. melanocephala seems to be a puzzle 

 to many entomologists, I give a full description of it 

 here : 



Black ; abdomen and legs reddish-yellow ; sides of abdomen yellow ; 

 coxae clear yellow, lined with black at base and at sides ; trochanters 

 clear yellow, black at base and apex ; four anterior femora marked with 

 black at the base. The abdominal segments are marked with black 

 transverse lines, and along the sides is a row of black marks. Palpi 

 white. Wings sub-hyaline, large, costa and stigma testaceous. First 

 radial ^ cellule longer than second; second cubital cellule nearly 

 equal in length to the second above, but much shorter on lower side, 

 owing to the third transverse cubital nervure having a very oblique 

 slope ; second recurrent nervure nearly interstitial. In the hind wings 

 the recurrent nervures are at the edge of the wing. Antennae longer 

 than the abdomen, thickish, microscopically pilose. Tegulaa white. 

 Cenchri large, clear white. 



Length 3 lines.
