662 REPORT UNITED STATES GEOLOGICAL SURVEY. 



The larvae, however, devour snails and insects, and do no injury to 

 vegetation. The larva of this species was identified by Mr. P. S. Sprague, 

 who found it near Boston, under stones in spring, where it changes to 

 a pupa, and early in May becomes a beetle, when' it eats the newly- 

 expanded leaves of the birch. 



Description. — The body of the larva is rather loug and slender, thickest in the mid- 

 dle, wliere it is about twice as wide as the head, and tapers slightly toward each end 

 of the body, the terminal segment being a little less than half as thick as the middle 

 segment. The segments of the body behind the head are unusually convex, the sutures 

 between them being very deep. The body is covered with fine, dense hairs, giving 

 ir. a peculiar velvety appearance. Its general color is horn-brown, the head being 

 darker. The head is remarkably flattened and square, being scarcely longer than 

 broad, and densely covered with short hairs above and beneath. The antennae are in- 

 Bertedon the side of the head, and immediately behind thera on tho side are the eyes; 

 the occipital suture is situated midway between the base and the front edge of the 

 head, forming a straight line just behind the eyes. Tho antennae are two-jointed, and 

 received into a large socket ; the first joint is very short; the second joint four times 

 as long as the first, a little slenderer, and increasing slightly in width toward the end, 

 •which is abrupt, and contains a minute, rudimentary third joint. The maxillae are 

 broad, subtriaugular, projecting a third of their length beyond the labium, with the 

 ends broad and square. The palpi extend out from the head as far as the antennae, and 

 are three-jointed, with the basal joint quite thick, rather longer than thick, while the 

 second joint is very short, and one-half as long as thick ; the third minute, rudimentary. 

 The anterior edge of the occiput beneath is deeply hollowed out ; the chin (mentum)is 

 oblong, with very square edges, and is one-fourth longer than broad. The labial palpi 

 are two-jointed, the basal joint very short, one-half as long as broad ; second nearly twice 

 .IS long as thick, and ending in a stift" hair. The mandibles are large, stout, two- 

 toothed, the inner tooth situated a considerable distance from tho tip. The labruni is 

 broad and perfectly square in front, with a median notch dividing the edge into two 

 slight lobes. The clypeus is an ill-defined oval, convex area. 



Along tho median line of the body is a slightly-marked row of short, paler streaks, 

 more continuous on the thoracic than the abdominal segments, forming on each of the 

 latter segments an elongated spot situated on the anterior edge of each segment except 

 the last. On each thoracic and the last abdominal segment is a pair of lateral oval 

 brown spots, paler in the center. Behind these on each abdominal segment (except the 

 last) is a row of pale short lines, placed in the middle of the segment. Farther down 

 on each side is a similar row of short lines, which are, however, subdivided into two 

 spots, which on the thoracic segments form a row of four or five pale dots. Between 

 these two lines is a row of black dots, one on each segment. The legs are rather short, 

 .and quite hairy. The terminal segment of the abdomen is about as long as broad, and 

 well rounded behind. It is three-quarters (.75) of an inch in length. The pupa was 

 not preserved. The beetle itself is soft-bodied, brownish-black and reddish-yellow. 

 Its specific name (Ulineatiis) was given to it from the two short, broad, blackish bands 

 on the prothorax, which is reddish-yellow. The head is reddish-yellow, with a broad 

 black band between the eyes, and the antennae are black. The body beneath is pale 

 reddish, except the under side of the middle of the thorax (meso and meta thorax). 

 The legs are pale reddish at base, while the end of the femora and the tibiae and tarsi 

 are entirely black-brown. It is about a third (.30) of an inch long. 



Whether this Telephorus larva devours the eggs, or young larvai, or 

 only the sickly and dying locust, is not known. 



Tlie groimd-hcetle gruh (Plate LXIII, Fig. 1, enlarged). — Another beetle- 

 grub, which is supposed to devour the eggs, has been received from Mr. 

 Whitman. It is the young of a species of Jlarpahis, and is allied to the 

 larva of the European IL ccneas, as figured by Schiodte, and may pos- 

 sibly be the young of //. lierhivcujus of Say, a very common beetle found 

 all over the country, having been collected by Lieutenant Oariienterin 

 Southern Colorado and Northern Mexico, according to Le Conte, so that 

 it probably destroys the locust wherever the latter occurs. 



The Imir-icorm paraHite [Gordins aqnaUcus Linn, and G. varius Leidj', 

 Plate LXIII, Fig. G, see explanation of the plate). — I have received from 

 Mr. Whitman fragments of a hair-worm found by him in the Rocky Moun- 

 tain locust, but, uufortunately, comprising neither end of the animal, so 

 that it is impossible to tell which species it is. It is probable that it 

 belongs to Gordius aquaticiis, as I have received one of that species from
