262 HOPLOCAMPA ALPINA. 



ally the marks on the mesonotum become confluent. 

 The ocelli are placed in a minute brownish splash. 



H. plagiata Klug. (1. c., p. 60), would seem to re- 

 semble this species (cratcegi) closely, if it be not 

 actually identical with it. From Hartig's descriptions 

 the differences between the two would seem to be that 

 the colour in plagiata is darker, the stigma reddish- 

 yellow (cratcegi has the wings clear with " blassem 

 Mahl "), the antenna brown, while it is half a line 

 larger. 



Not common. Boxhill, on flowers of hawthorn 

 (Marshall). Norfolk, Norwich. 



Continental distribution : Scandinavia, Germany, 

 Holland, France.

 cratcegi, Cam., Fauna, 26, 1. 



Pale testaceous ; wings with nervures and costa milk white ; an- 

 tennae, posterior tarsi, abdomen at apex, one or two marks on mesonotum, 

 sometimes fuscous ; tibiae, tarsi and tegulae paler than the rest of the 

 body. 



The <$ has the tarsi and antennae devoid of the fuscous tint. 



Length 2 lines. 



The body is narrower than in the preceding species, 

 the antennae longer and thinner, the wings if anything 

 larger in proportion, and the saw shorter. The ocelli 

 are not enclosed in a black or brownish spot, the marks 

 on the mesonotum are generally obsolete, while as 

 often as not the antennas are entirely pale yellow. The 

 < differs from that of cratcegi in the body being 

 entirely of one colour. 



Not common, but commonly distributed, appearing 

 early in June on Pyrus aucuparia. Scotland, at Brae- 

 mar, Altnaharra, Sutherlandshire, and in Clydesdale. 

 I have also seen English specimens in Mr. Marshall's 

 collection, bearing the name of H. pallida, Newm., but
