GENUS BLENNOCAMPA. 229 



scarcely the case with rosce on the upper side, by the 

 hinder tibiae being longer compared to the tibiae,, and 

 by the different coloration of the posterior legs. 



I am not sure but Eriocampa dolosa, Evers. (Bull. 

 Mosc., xx, 33, 16), is the same species. His descrip- 

 tion is : Nigra, nitida, geniculis, tibiis, tarsisque 

 sordide lutescentibus ; alis limpidis, stigmate-radioque 

 fuscis ?. The term, "limpidis" can scarcely be 

 applied to the wings of testaceipes, while Eversmann 

 makes no mention of the neuration of the wings (save 

 that there is but one middle cellule in hind wings) nor 

 of the form of the clypeus, so that in the meantime I 

 prefer to retain my own name. 



Taken on 6th 'June on alder at Kilmorack, near

Genus BLENNOCAMPA. 



Blennocampa, Htg., Blattw., 266. 

 Monophadnus, Htg., 1. c., 271. 

 Phymatocera, Dbm., Clavis, 4. 

 Pectinia (Lep.), Brulle, Hymen., iv, p. 664. 



Wings with two radial and four cubital cellules; the second and 

 third of the latter each receiving a recurrent nervure. Lanceolate 

 cellule petiolate. Posterior wings with the transverse cubital nervure 

 always absent, but the recurrent in one section (== Monopliadnus, Htg.) 

 is present. Antenna} short and thick, or longish and filiform ; the third 

 joint longer than fourth, or densely pilose with the third shorter than 

 fourth. Body short, thick, and rather ovoid in form, the abdomen being 

 rarely much longer than the head and thorax. 



The neuration is varied as regards the position of the nervures in the 

 different species. The basal nervure is straight and runs parallel 

 with the transverse cubital, or it is curved and not parallel. The trans- 

 verse median nervure is generally received before the middle of the 

 cellule, but sometimes is received beyond it, i.e. nearer the base of the 

 cellule. In B. betuleti and B. nana the first transverse cubital nervure 

 is absent, or at least is very faint, so that these two species have pretty 

 much the neuration of Fenusa, with which they agree in some other 

 respects. 



The clypeus is, as a rule, truncated or but slightly emarginated at 

 the apex. The pentagonal area is rarely indicated, but the frontal 

 sutures are distinct. The mandibles are short and broad, and have a 

 tooth not far from the blunt apex ; behind the subapical tooth the 

 edge may be indented (see PI. XII, fig. 12). 



The only noteworthy peculiarity as regards the
