FENUSA QUERCUS. 185 



In the table given in Vol. I, p. 284, this species 

 will come in as follows : 



5 (2) Antennae 12— 13-jointed ; wings for the greater part smoky. 



5a (5b) Wings uniformly fuscous; tegulse and a narrow line on the 

 pronotum white ; legs black, the trochanters, knees, and tibise 

 beneath, white ; abdomen ochreous above. Fumipennis. 



5b (5a) Wings smoky, hyaline at the apex; tegulse black; legs pale 

 yellow, black at the base ; abdomen not ochreous above. 



Ochropoda. 



P. fumipennis is a smaller and broader species than 

 ochropoda, the abdomen especially being broader and 

 not much longer than the head and thorax united ; the 

 head between the antennce is broader, natter, and does 

 not project so much, the antennae also being more 

 widely separated. 



Taken at Norwich on alder by Mr. J. B. Bridgman. 



Genus Fenusa (Yol. I, p. 290). 



As already (p. 173) indicated, Konow places Fenusa 

 and Fenella among the Blennocampides, and separates 

 TJlmi, Pumila, and Melanopoda from them into Kalio- 

 syphinga, Tisch., the latter being distinguished from 

 Fenusa and Fenella by " there being no anal cellule in 

 the hind wings, and by the humeral nervure distinctly 

 bending towards the brachial nervure, so that the lan- 

 ceolate cellule appears widely contracted, Fenella and 

 Fenusa having a closed anal cellule in the hinder wings, 

 while the humeral nervure in the fore- wings is absent 

 or straight. In Fenella (at least in nigrita and West- 

 woodi, the only species known to me from autopsy) 

 there is no closed anal cellule in the hind wings. 



Fenusa querotjs (Vol. II, p. 222). 



Mr. Fletcher is now of opinion that he was in error 

 in supposing that this insect mined the leaves of the
