DESCRIPTION OF AN EUPITHECIA NEW TO SCIENCE. 231 



dark markings, pointing forwards, followed by a less well-defined 

 roundish marking to the anal segment. Sometimes these spear- 

 head-like markings appear almost lozenges Under each of the 

 spearheads is a dark streaky mark, placed diagonally, the wrinkled 

 edging to which is light and well-defined ; anal segment without a 

 plate. 



Pupa.— Rather obese. Face, thorax, and wing-cases bright 

 grass-green. Anterior segments bright red-ochre colour. Spins 

 a slight web of white silk at the base of its food-plant amongst 

 the debris lying about, and pupates therein. 



Remarks. — General appearance of full-grown larva: form 

 long, slender, central segments broadest, slightly appressed. 

 Colours various, from bright green to rich chocolate-brown, and 

 with six well pronounced spear-head or lozenge-shaped dorsal 

 markings, edged diagonally with light green. It is a rather 

 slender, wrinkled, " pug" larva, and belongs to the absynthiata, 

 satyrata and knautiata group of Eupithecia, but has a much more 

 elegant appearance than these in both the larval and imago state. 

 It is the most lineolate Eupithecia I know. The moth appears 

 in plenty at Balta Sound, in Shetland, on heathy places, its 

 larva eating Calluna vulgaris; it was taken there during June, 

 1884, by Mr. E. Roper-Curzon, from whom I have received a most 

 liberal supply of perfect insects and the larvae from which this 

 description is written. 



This is probably the insect figured in the ' Entomologist ' 

 (vol. xiv., plate i., figs. 2 and 3), and there supposed to be E. 

 satyrata or E. nanata (page 303), and which was to receive future 

 consideration. In the absence of that consideration, up to the 

 present time, I have thought it best to wait no longer, and 

 therefore have described the species from the long series of 

 specimens captured and given to me b}' my friend Mr. Curzon. 

 I have named it in his honour Eupithecia curzoni. In the 

 arrangement of the genus Eupithecia, in British collections, 

 this species should precede E. satyrata; but it has nothing 

 common in appearance with that genus, except perhaps its 

 shape ; the arrangement by the larvse as followed in France 

 alone places it there. Following Newman's plan in ' British 

 Moths,' of giving English names to all species before the 

 scientific name, this will be called " Curzon's Pug.''
