178 Mr. R. MacLachlan's Monograph oj 



Wings long, rounded at the apex, uniformly pale smoky 

 fuscous; pterostignia with a brownish tinge; neuration 

 fuscous, without dots, strongly hairy ; in the anterior 

 wings are three sectors ; four veinlets in the outer gradate 

 series, five in the inner, three towards the base. 



Length of body 2-3 lines; expanse of wings 5-6 j lines. 



Found by Mr. Dale, in summer, in old furze-bushes, 

 at Bournemouth, Hants. 



This has considerable resemblance to small examples 

 of H. nitidulus, but differs in its narrower wings, and 

 undotted veins, and especially in the extraordinary form 

 of the male appendices. It also greatly resembles Sisyra 

 fuscata in outward appearance. 



In my Continental Collection I have a ? from Silesia 

 taken by Zeller, and 3" ^^^ ? from France. 



The ventral lobe in the (J has the appearance of an 

 ovipositor, and had I seen that sex only, I should pro- 

 bably have mistaken it for the ? , but the matter is set 

 at rest by the examples in Mr. Dale's Collection. An 

 approach towards this formation is seen in H. elegans. 



The large Continental and American species which I 

 consider to be H. longifrons of Walker (See Journ. Linn. 

 Soc. ix. 273; 1867) has an analogous lobe, and I re- 

 ferred all the examples to the female sex, but an examina- 

 tion of the male of H. inconspicuus has created some 

 doubt in my mind as to the correctness of my determi- 

 nation, especially as Herr Brauer sent me an insect of 

 similar appearance, which is decidedly female, but has 

 no evident borer.
