time the distal extremity assumed the form of a sort of cap, con- 

 stricted from side to side. 



The egg hatched on June 22nd, tluis giving a fortnight as the 

 duration of the egg- stage ; but in the two or three days before hatch- 

 ing, it became rather darker in colour, and showed a reddish-brown 

 streak at the base, and a reddish stain near the apex. Unfortimately, 

 again, I did not see the actual disclosure of the larva, but it was 

 evidently accomplished by the thrusting up of the apical cajj, which 

 had, however, after the emergence, fallen back into position. The rest 

 of the egg-shell was entire, so that the whole egg was very little 

 altered in appearance by the disclosure of the larva, save for its 

 obvious emptiness. In this condition the cap is completely hyaline, 

 but the rest of the shell milk-white. 



The newly-hatched larva has an almost cylindrical body, slightly 

 swollen at the head, and gently tapering to the end of the abdomen ; 

 the antennae are long, much longer than the body, and the apical joint 

 is stouter than the rest, thus contrasting strongly with the imago, in 

 which this joint is the thinnest. The antennae were continually in 

 motion, in the manner characteristic of the imago, viz., the right and 

 left alternately up and down. They were frequently cleaned by being 

 stroked with the front tarsi, and then these were rubbed against one 

 another. The head is yellowish, the abdomen greenish, and the 

 antennae reddish at the apex. On the dorsal surface of the second 

 abdominal segment there is a distinct yellow spot. The head is 

 rounded in front, broader than the rest of the body, and with 

 a furrow down the middle of the vertex, specially strongly marked 

 behind. Dor sally, the three thoracic segments are similar to one 

 another, the pronotum being the largest. Of the two tarsal joints, 

 the first is very small and the second large ; the claws also are 

 large. The four-jointed rostrum is long, and in use, the setae, 

 when fully thrust into the grass, were guided by the apex of the 

 fourth joint, and the junction of the second and third, so that the 

 labial trough separated from the setae in two angles, one at the junc- 

 tion of the first and second joints, and the other at that of the third 

 and fourth ; this may be contrasted with what is said above as to the 

 position in the imago. The legs are comparatively stout and slightly 

 dusky. The cast skin shows that this duskiness lies in the epidermis ; 

 the true colour of the insect is situated beneath this, and does not 

 appear in the exuviae ; the only exception to this statement is that 

 there is a yellow streak in the exuviae where the yellow spot appears at 

 the base of the abdomen in the larva.
