TZENIOCAMPA OPIMA. 57 



shining, the latter dull with front margin darker, the 

 dorsal and subdorsal lines very thin, and paler than 

 the ground , tubercular dots paler, still in threes, but 

 so small as not to be noticeable without a lens ; 

 spiracles oval, white, finely outlined with black. The 

 colouring by degrees in a day or two on the back and 

 sides turns of a rich velvety brown, and, just at last, 

 of a crimson-brown, in strong contrast to the brilliant 

 greenish-yellow of the belly and lighter yellow spira- 

 cular stripe. 



They have been from the very first most vora- 

 cious feeders in proportion to their size, consuming 

 great quantities of sallow. They began to enter the 

 earth, a few on June 4th, 5th, 6th and 8th, and at 

 intervals up to the 18th. The moths appeared from 

 the 11th of March to the 27th of April, 1881. (W. B., 

 1881, Note Book IV, 10.) 



T^NIOOAMPA GRACILIS. 



Plate LXXXI, fig. 5. 



Variety of the larva of Tseniocampa gracilis. — To 

 those who know the larva of this species only in its 

 more usual bluish-green, or yellowish olive-green coat, 

 the following description, given me by Mr. Buckler, 

 of a variety sent him from Epping, will seem strange ; 

 but there can be no doubt as to the moth which was 

 bred from it. 



The ground colour of the larva was deep broivn 

 tinged with pink, the slender dorsal and subdorsal 

 lines of the same, but showing rather paler ; along 

 the region of the spiracles, and reaching half-way 

 down the anal pro-legs, a broad stripe of pale dingy 

 pink, sharply edged above with a fine blackish line ; 

 belly and legs of the ground colour ; the usual dots 

 appeared dark brown within paler rings, and the back 

 was slightly freckled with the paler tint. (J. H., 

 February 23, 1865, E.M.M., I, 283, May, 1865.)
