state it remains about fourteen days. The imago appears in July. I am indebted to

Description of the Larva of Liparis monaeha. — The egg is laid in the autumn, in 

 the crevices of the bark of Quercus Robur (oak), Pinus sylvestris (Scotch fir), and 

 other trees, and hatches the following spring as soon as the leaves are expanded. The 

 larva is not full-grown until late in June ; it then rests in a nearly straight position, 

 and does not readily fall off its food, nor does it feign death if disturbed. Head 

 scarcely so wide as the body, prone, hairy on the cheeks near the mouih : body obese, 

 rather depressed, aud slightly dilated on the sides, each segment having six con- 

 spicuous warts arranged in a transverse series, and forming together six longitudinal 

 series ; the second wart on each side of ihe 2nd segment is seated on an evident fleshy 

 tubercle, which projects sideways and then slightly forwards ; and all the other warts 

 of the second longitudinal series on each side partake of this tubercular character; 

 each segment has moreover two very small, approximate, dorsal waits, in addition to 

 the six more prominent ones I have described : every wart emits a fascicle of radiating 

 stiffish bristles; the 10th and 11th segments have moreover a medio-dorsal valvular 

 opening. The head is gray, delicately reticulated with black : body beautifully varied 

 with delicate shades of green-gray, yellow-gray and smoky brown : the dorsal surface 

 is yellow-gray ; the warls very dark, almost black ; the hairs on the warts of the first 

 and second longitudinal series are black : the dorsal warts on the 3rd segment are 

 connected by a transverse black fascia ; the dorsal surface of the 4th, 5th, 6th and 7th 

 segments between the warts, is reticulated with smoky brown ; similar reticulations 

 form a decided patch on the dorsal surface of the 9th, 10th and 11th segments ; this 

 patch is restricted and indented at the incisions of the segments: sides green-gray ; 

 the dark colour of the second series of warts on each side, connected in some degree 

 by dark reticulations, gives the appearance of a dark lateral or spiracular stripe : belly, 

 legs aud claspers green-gray, claspers much dilated at the extremity. It spins a very 

 slight web on the branches of trees, and in a week changes to a pupa, brown with a 

 tinge of bronze, and furnished on every segment with lax fascicles of bent red hairs ; 

 immediately behind the head are two fascicles of bristle-like black hairs, and behind 

 these a third of the same kind : the anal extremity is black, and furnished with a 

 number of minute hooks. The web consists of a few threads only, and does not in 

 any way hide the pupa. The imago appears in July and August. I am indebted to 

 Mr. Wright for specimens of this larva. — Id. 



Description of the Larva of Orgy ia anliqua. — The eggs are laid in July, August, 

 September, and even October, on a nearly flat web, spun by the female larva as u 

 cocoon in which to undergo pupation : they are nearly spherical, but slightly depressed 

 on the summit: when first laid they are beautifully glabrous and pure white, except a 

 brown spot in the very centre of the depression, and a brown ring surrounding the 

 spot: they are arranged compactly, touching each other, and remain in that state 

 throughout the winter; they do not hatch simultaneously, but emerge in succession, 

 one after the other, the hatching period of a single batch extending over many days 

 or even weeks ; hence some of the larva? are full-fed while others have not yet escaped 

 from the egg ; this peculiarity will account for the constant succession of larva; we 

 observe in our gardens. The larvae when hatched seem to exercise no choice in the 

 selection of a food-plant, but eat indiscriminately of every leaf that the garden sup- 

 plies. The full-fed larva rests in a nearly straight position ; it falls off its food-plant 

 when annoyed, and remains for a short time in a curved posture, which can scarcely
