punctures and uniform very short hairs. Elytra more yellowish brown, 

 dilated at the lower sides anteriorly, and with about nine deeply punctured 

 stri;e, the stri;o themselves sometimes obsolete ; more or less covered with 

 coarse and short pale yellow hairs which form by their greater density three 

 more or less conspicuous transverse bands, the first of which is at the base; 

 between the second and third band in the middle of the elytron, is a smooth, 

 dark brown or black spot, with a less distinct spot of the same color below 

 the third, and a still less distinct one above the second band. Length .16 

 inch. Described from four specimens bred from strawberry-boring larva?. 

 The black spots on the elytra are quite distinct and conspicuous on two 

 specimens, less so on one, and entirely obsolete on the other." 



Larva — White, except the head, which is pale yellow. The mandibles are 

 dark brown, black at the edges, and bifid at the tip. The labrum is nar- 

 rowed from behind ; broadly rounded, entire and bristly in front, and marked 

 by a transverse suture before the middle. The antenna?, situated ovit- 

 side the upper angles of the mandibles, are one-jointed and excessively 

 minute, being about .02 mm. in length. Just outside each antenna is a black 

 ocellus-like spot in full-grown larva?, wanting in smaller individuals. The 

 head is smooth, except for about three transverse rows of slender hairs. 

 The body is strongly arched, like that of a lamellieorn, each segment bear- 

 ing a single row of very short sparse hairs. The first segment of the dorsum 

 is smooth ; the remaining segments are divided into three transverse lobes 

 or folds, the first and last of which are interrupted near the end by oblique 

 grooves. Below the spiracles is a row of large, low, triangular tubercles, and 

 beneath these a second row, separated from the former by a longitudinal 

 channel. The ventral segments of the abdomen have the usual form of a 

 single transverse ridge, a triangular portion of each end of which is marked 

 off by an oblique groove. The structure of the segments is, in fact, almost 

 precisely that of the strawberry root-worm, to be hereafter described. The 

 pectoral ridges of the thorax, however, bear upon each side, instead of feet, 

 three large fleshy tubercles, each with two or three stiff hairs at the tip. 

 This larva, when stretched out, is one-fifth of an inch in length by one-half 

 that width. 



Pupa. — The pupa is white throughout, with the exception of the eyes, 

 which show through the pupal envelope at the base of the snout. The head 

 and snout are bent against the breast; the second is about twice as long as 

 wide, broadening towards the tip, where it is widely emarginate. The 

 clubbed antenuie extend scarcely beyond the tip of the snout. The middle of 

 the head bears two longitudinal rows of stifi' bristles, four or five in each 

 row, and three rows of similar bristles extend transversely upon the thorax, 

 while others surround the margin. The posterior edge of each abdominal 

 segment is likewise bristled, and a pair of incurved hooks terminates the 

 abdomen.
