the British, Neuroptera-Planipennia. 185 



Wings shorter and broader than in H. limbahis, the 

 apex broadly elliptical : anterior pair whitish-hyaline ; 

 a few gray markings across the veins ; the gradate vein- 

 lets broadly margined with fuscous, giving the appear- 

 ance of two fuscous fasciae, and many blackish spots at 

 the base, at the axillae of the furcations and on the longi- 

 tudinal veins, these veins being otherwise whitish ; costal 

 veinlets more finely spotted ; gradate veinlets black, 

 seven to eight in the outer series, six in the inner, two 

 near the base ; three sectors ; pterostigma scarcely indi- 

 cated ; the apical and dorsal portion of the wing without 

 any evident margining : in the posterior pair the gradate 

 veinlets, the greater part of the second sector and of 

 the sub-costa and radius are blackish, and the rest of the 

 longitudinal veins have black streaks in the apical half ; 

 neuration otherwise pale. 



Length of body 2| lines; expanse of wings 6-6^ lines. 



Not unfrequent throughout the summer. 



This is evidenty allied to the true H. fasciatus of 

 Gozsy, and may be a form thereof ; but the latter would 

 appear to be larger and to have the wings longer (inter- 

 mediate between the present insect and limhatus in this 

 respect), with an absence of the sharply defined black 

 spots, the markings taking the form of three or four 

 more or less distinct transverse fuscous fasciae. I have 

 not met with British examples that I can confidently 

 refer to fasciatus, which would seem to be a common 

 species on the mountains of central Europe, judging from 

 numerous specimens received from Zeller. 



H. crispus (Leach), Stephens, may belong here as 

 a pale form, but I cannot satisfactorily determine it from 

 the single type. 



There are four or five European species pertaining to 

 the limhatus group ; and one or more of these certainly 

 occurs also in North America. I have specimens of 

 atrifrons also from Prussia, Austria, etc.
