EUPITHECIA SUBCILTATA. 47 



extremities ; the skin seems tough, and the segments 

 being transversely wrinkled give it a puckered appear- 

 ance. 



There are two well-marked varieties, which, judging 

 from those sent me, are about equally common. 



The form we will take as var. 1 has the ground 

 colour yellowish-green, the green colour being 

 strongest on the anterior segments ; the head is 

 almost green ; a deep purple broad stripe, still darker 

 at the segmental divisions, forms the dorsal line ; a 

 pale shade of purple is also suffused rather broadly 

 on each side of the dorsal Hue ; the subdorsal lines 

 are greyish-white ; there is an equally pale waved 

 stripe above the spiracles, and a pale but greener 

 stripe along the spiracles. The ventral surface is 

 uniformly dingy green. 



Var. 2 has the ground colour bright yellowish green, 

 the head tinged with brown ; a dark green pulsating 

 vessel forms the dorsal line ; subdorsal lines greyish - 

 white ; there is a similarly coloured waved line above 

 the spiracles, and a pale greenish stripe along the 

 spiracles ; the segmental divisions are yellowish. The 

 ventral surface is uniformly bright pale green tinged 

 with yellowish. 



At the end of the month these larvae spun up 

 between the leaves and amongst the flowers of maple. 



The pupa is scarcely a quarter of an inch long, and 

 somewhat stumpy ; it is smooth and polished, rounded 

 on the upper side, and has the wing-, antenna-, leg-, 

 and eye-cases prominent. The colour is pale brown, 

 with the segmental divisions darker and the wing- 

 cases yellowish. 



The imagos appeared early in August. (George 

 T. Porritt, 5th July, 1877; E.M.M., August, 1877,
