NOTES ON EUPITHECIA LARV^. 141 



enclosed in a tightly-spun earthen cocoon, has the wing- 

 cases bright green, the nervures very prominent; thorax 

 yellowish-green ; abdomen reddish-yellowish, Mith a dark 

 green dorsal line. The perfect insect appears in June and July. 



Eupithecia minutata. Short, thick and stumpy. Ground- 

 colour dull pink or flesh tint, with a series of dusky Y-shaped 

 dorsal spots, connected by a central pink line, and becoming 

 faint on the anterior, and almost obliterated on the posterior 

 segments. Each dorsal segment studded with four yellowish 

 tubercles. Spiracular line yellowish, interrupted at intervals 

 by dusky blotches. Head dusky oHve, marked with black. 

 Belly dusky or pinkish-white. Back thickly studded with 

 small white, and a few black tubercles, and sprinkled here 

 and there with short hairs.* Feeds on the flowers of CaU 

 luna vulgaris in August and September, and is by no means 

 uncommon where that plant occurs in plenty. Pupa enclosed 

 in an earthen cocoon. Short and thick. Thorax and wing- 

 cases golden yellow ; abdomen yellow, generally sufl'used 

 with red. Wing-cases very transparent. Tip of abdomen 

 blood-red. 



Eupithecia assimilata. Slender, tapering slightly towards 

 the head. Var. 1. Ground-colour vellowish-o^reen. Sesrmental 

 divisions yellow. Central dorsal line dark green. Sub-dorsal 

 ones dark green, very indistinct. The latter occasionally 

 studded at intervals with black spots. Body thickly sprinkled 

 with small yellowish-green tubercles and thinly strewed 

 with short whitish hairs. Strongly resembles a young larva 

 of E. cervinaria. Turns pinkish when ready to spin up. 



* During the past summer, 1860, I reared a small brood from eggs on 

 flowers of Achillea millefolium; besides the typical form just described, 

 there were several gay-coloured varieties resembling Vars. 1 and 2 of 

 E. satyrata, and Var. 2 of E. cormiata. I also reared four or five larvae 

 from eggs on flowers of Anthriscus sylvestris ; these were also variable in 

 colour.
