the allied species. In fact, the whole account was far in advance of 

 the times. He bred the insect, but possibly confused more than one 

 species in the larval state. Now that attention has been called to the 

 subject the matter may be left for elucidation, and more especially by 

 Scandinavian entomologists. Schoyen (Christiania Vid. - Selskabs 

 Forhandl., 1887, No. 13) referred betulinus doubtfully to suhnebulosus. 



H. suBNEBULOSus, Steph. 



Of the same form as H. nervosus, but as a rule with 

 the anterior wings lees mottled. 



In the (J the appendages have a broad, straight, 

 basal portion, from which the very narrow apical portion 

 descends at a right angle and is strongly incurved at the 

 tip, which is furnished externally with a barb, the outer 

 edge of which is finely serrate for its whole length, 

 the tips often crossing if viewed from beneath. 



Possibly found all over Europe and ad- 

 jacent districts. In England it is especially a 

 garden insect, and as such liable to be dispersed 

 with plants and shrubs. Occurs in the interior 

 of London, and one of the first to appear in 

 in spring. I have it from Portugal and Madeira. 

 In most English examples the anterior wings 

 appear almost of a pale leaden-grey, requiring 

 magnifying power to break up into (mostly) 



angulate markings, but those from southern Europe are much paler. 



I may be wrong, but it has occurred to me that the specimens from 



in and around London are the darkest of all. 



H. MoETONi, n. sp. 



Having the anterior wings apparently broader and more obtuse than in the two 

 preceding, arising from the costal edge being more arched (hence the costal area is 

 broader, especially at the base). As a rule less strongly mottled than in nervosus, 

 and less uniform than in suhnebulosus. 



The anal appendages of the (J having the basal 

 portion straight and rather broad, the apical portion 

 descending from it at a right angle in the form of a 

 straight short process, with no barb at the apex, but 

 the tip obscurely toothed, and microscopically ser- 

 rate on the edge if viewed from beneath. A further 

 character for this species is that in the <J the dorsum 

 of the apex of the abdomen is rather densely clothed 

 with golden coloured hairs. 



Apparently a boreal and alpine species, 

 but very wdde-spread ; probably always f re-
