in Mr. Newman's account, as quite opposed to my experience, was the period given 

 by him for the full growth of the caterpillar, viz. the beginning of July, on no single 

 occasion have I ever found the larva full fed before the end of that month ; in fact, 

 just about the period when Mr. Newman's moths emerged. The perfect insect itself 

 I have frequently beaten out of oak, and, upon referring to my note-book, I find the 

 earliest date to be the 14th of August. Mr. Newman, I am sure, will not regard 

 these remarks as in any way reflecting upon his accuracy, but simply as a contribution 

 to the history of the insect when in a "state of nature." — Joseph Greene. 



[This is exactly the kind of correction that I desire. The larvae being only known 

 to me in a state of captivity, I saw the almost inevitable necessity for some emenda- 

 tions both as to food and date. I shall be extremely obliged for specimens of 

 Ennomos erosaria in the perfect state for the cabinet of the Entomological Club: 

 I have not one tolerable specimen. — Edward Newman ^] 



Description of the Larva of Tephrosia crepuscularia. — Eggs laid in July, and 

 hatched the beginning of August. Larva rests in a nearly straight posture, the middle 

 segments sometimes arched, aud the head porrected. Head narrower than the body, 

 having a deeply impressed triangle on the face. Body almost uniformly cylindrical, 

 but having the 3rd segment swollen all round, and the 4th segment swollen below, the 

 swelling bearing the third pair of legs; there ale two small warts on the back of the 

 12th segment, and the 13th segment has three short mamillary points below the anal 

 flap and directed backwards : skin of the body much folded transversely. Colour of 

 the head brown mottled : colour of the body wainscot-brown, with six very narrow and 

 very indistinct darker rivulet stripes extending the entire length of the back ; these are 

 associated in three pairs, the stripes in each pair being closely approximate and in 

 some parts scarcely separable ; on the 6th segment the lateral stripe ascends obliquely 

 towards the median line of the back ; between each pair of stripes are several black 

 dots ; the sides of the larva exterior to these stripes are paler, especially on the 7th, 

 8th and 9lh segments, and the back of the larva is manifestly darker on the 8th seg- 

 ment; there is a triple yellow spot on each side of the 10th segment close to the ven- 

 tral claspers. The legs are brown, the claspers paler. Feeds on Pinus Larix (larch), 

 Betula alba (birch), and Quercus Robur (oak), and is double-brooded; the larva of the 

 second, which is now described, is full fed at the end of September, when it descends 

 to the ground and spins a slight web, generally among fallen leaves, where it changes 

 to a pupa, in which state it remains all the winter. The first brood of this species 

 used to swarm in the larch plantation nearly opposite the Inn at Birch Wood Corner 

 in March aud April, but since these trees have been cut down the species has disap- 

 peared. Eggs laid by the spring females produce moths, in confinement, in July and 

 August; but I have never seen the summer brood at large, and Mr. F. O. Standish 

 has made the same remark to Mr. Doubleday, who has bred the early brood in Febru- 

 ary ; but it may be remarked, as a general rule, that insects appear earlier in confine- 

 ment than at large. I am indebted to Mr. Thomas Huckett for the opportunity of 

 describing this insect. — Edward Newman. 



Description of the Larva of Boarmia biundularia. — Egg laid by a captured female 

 from the 21st to the 27th of May ; larvae hatched on the 4th and 5th of June. Rests 

 in a nearly straight posture. Sometimes the middle segments form an arch, as in 

 walking. Head semiporrect, narrower than the body, with a deeply impressed 

 triangular mark on the face. Body almost uniformly cylindrical, but with the 3rd 

 segment swollen above and at the sides, and the 4th segment swollen beneath, and
