182 Mr. R. MacLachlan's Monocjraph of 



This insect lias much the appearance of H. humuli, but is 

 very distinct, as is proved by the form of the male ap- 

 pendiceSj and also by the shape of the wings, &c. 



The species has never hitherto been properly described, 

 though it has been duly separated by Neuropterists ; thus 

 in Zeller^s collection, I find it with the MS. name 

 *' diversus" of Schneider, and I have received it from 

 Brauer as " superhus," n. s.

TJnicolorous, brownish or blackish-brown ; antennce 

 brown, with scarcely evident narrow pale annulations. 



Abdomen brown, with paler pubescence. In the ^ the 

 appendices are blackish or fuscescent, broad, deeply fur- 

 cate, the prongs diverging, and each slightly curved at 

 the tips in opposite directions ; the upper prong slightly 

 the longer, and crossing the corresponding prong of the 

 other appendix (PL X. fig. 7) . 



Legs grayish-yellow, fuscescent at the knees and at 

 the tips of the tarsi. 



Wings longly and narrowly ovate, longly elliptical at 

 the apex : anterior pair grayish or brownish, with short 

 gray streaks crossing the veins, the gradate veinlets mar- 

 gined with fuscous, more or less distinctly ; the apical 

 and dorsal margins generally broadly pale brownish, but 

 varying greatly in this respect ; longitudinal veins and 

 costal veinlets pale, very closely pointed with fuscous ; 

 pterostigma brownish or reddish ; three sectms ; gradate 

 veinlets dark fuscous, seven in the outer series, six in the 

 inner, two near the base : posterior pa/ir grayish-hyaline ; 

 pterostigma brownish ; neuration unspotted, for the most 

 part fuscescent, the sub-costa and radius more testa- 

 ceous ; the apical and dorsal margins frequently show 

 a trace of the broad darker margination, as in the 

 fore- wings. 



Length of body 2^-3 lines; expanse of wings 7-8 lines.
