Description of the Larva of Anarta Myrtilli. — When full- 

 fed it rests with the 2nd, 3rd and 4th pairs of ventral claspers, 

 as well as the anal claspers, firmly attached to the food-plant, 

 the anterior part of the body raised, and the head bent under 

 Sphinx-like ; the first pair of claspers are held free : when 

 disturbed it falls from its food-plant and rolls into a compact 

 ring, but does not long retain that position, soon unrolling 

 itself and crawling with considerable activity. The head is 

 of the same width as the 2nd segment, the cheeks rounded, 

 the crown not conspicuously notched, the whole extremely 

 glabrous, yet emitting several bristles : the body is uniformly 

 cylindrical. The colour of the head is pale transparent green, 

 with a number of dark brown dots ; the 2nd segment of the 

 body has a dull green plate occupying its entire dorsal sur- 

 face ; the remainder of the body is olive-green, decorated 

 with numerous pale markings ; there is a medio-dorsal series 

 of eleven spots, all of them guttiform or elongate-oval; on 

 each side is a series of eleven spots, almost semicircular, but 

 not perfectly so, and each of these is divided at the junction 

 of the segments ; there is still another series in the region of 

 the spiracles, and these are more united, forming a zigzag 

 line ; the spiracles themselves are white ; each is surrounded 

 by a black ring ; the ventral surface has a chain*like series 

 of pale markings, extending to all the segments except the 

 2nd, 3rd, 4th and 13th : the legs and claspers are of the 

 ground colour, but each has a pale streak at the base, and on 

 all parts of the body are numerous smaller markings, inter* 

 vening between those 1 have described : these various mark- 

 ings are far from constant in form, number or colour; their 

 ordinary colour is that called albidus in Latin descriptions, 

 an impure white, but sometimes they are pure white and 

 sometimes tinged with yellow ; in one specimen I find the 

 lateral series alternately pure white and dingy white ; the 

 dorsal area also varies in tint, bright green, olive-green, olive-
