upper angle with an inturnecl tooth, the lower obtuse ; on the upper edge, towards 

 the apex, there is a short, straight, acute horn or tooth directed upward, and having 

 its origin on the inner face of the appendage. 



Probably au abundant species all over Europe amongst deciduous 

 trees (more rarely on Conifers), but never properly elucidated, inas- 

 much as the anal parts have never been described and figured. 

 Rostock's tabular diagnoses of this (which he considered Jiumuli) and 

 the following (which he considered orotypus) are excellent so far as 

 they go. 



1 have adopted the name given by Fabricius, because there is 

 nothing in the description opposed to the identification, but, on the 

 contrary, everything in favour of it. In the year 1866 Hagen sent 

 me sketches of the appendages of several species of Hemerohiiis, and 

 this was indicated as lutescens^ yet in the same year, in his " Synopsis 

 Synonyuiica," he referred concinnus, Steph., to lutescens, an associa- 

 tion impossible from the size alone, as he had probably discovered. 



This species has been indicated in some recent British local lists 

 as "orotypus^'' an error for which I am primarily responsible.

Pale primrose-yellow ; a broad blackish stripe on each side of the thorax (often 

 seen on the sides of the head above), as broad as, or broader than, the pale band 

 enclosed thereby : antennse distinctly annulated with fuliginous, the apical portion 



often decidedly darker : 

 abdomen usually blackish 

 in the dry insect : legs 

 pale, somewhat dusky 

 (from hairs), the tarsal 

 joints vaguely annulated, 

 the terminal joint usually 

 wholly darker. Anterior 

 wings broad-oval, with a 

 greyer tinge than in the 

 last species ; the sub- 

 basal black point usually 

 very conspicuous, there 

 are smoky-grey spaces along the dorsal margin invading the membrane, and the 

 gradate series of nurvules are conspicuously clouded with smoky-grey, the black 

 spaces on the neuration are apparently more numerous than in the last, and more 

 punctiform, and the points at the origins of the sectors of the radius are much
