The cocoon was a quarter of an inch long, two lines broad, of a very short 

 elliptical form, bearing a great resemblance to a gall excrescence ; a few fine threads 

 formed a kind of net- work round its base attached to the leaf; it was dark dull brown 

 in colour, with blotches of a pale grey film spreading irregularly over the vipper 

 surface, as though it bore a delicate lichenous growth. 



The pupa skin when extracted was but a trifle less than a quarter of an inch 

 long and thick in proportion ; the abdomen bent under, which gave it a rather rounded 

 form ; the abdominal segmental divisions were distinct, as were the parts of the head 

 and thorax ; the wing-cases were well developed and projecting ; it was all very 

 smooth and jDolished, and of a transparent whity-brown colour. — William Bticklee,

Description of the larva of Ephyra pendnlaria. — In August last, I beat rather 

 commonly from birch in Sherwood Forest, two very distinct varieties of the larva of 

 this species, and am not aware that a description of either of them lias been published : — 



Length rather over an inch, and rather slender ; the head small, the same width 

 as the second, but naiTower than the third segment ; it has the face flattened, and 

 is notched on the crown. Body of tolerably uniform bulk, attenuated slightly from 

 the posterior to the third segment, which is swollen laterally. The skin has a very 

 slightly puckered appearance, and the segments overlap each other, rendering the 

 divisions conspicuous. 



Var. 1 has the ground colour pinkish-purple, in some specimens greyish-purple ; 

 head dark sienna-brown, the mouth, and a line down each side the median suture, 

 dull ochreous-yellow. Throughout the dorsal area extends a broad, pale, smoky 

 band, having through its centre the pale grey medio-dorsal line ; bordering this 

 band on each side are the interrupted, indistinct, similarly coloured sub-dorsal lines ; 

 there ?re no perceptible spiracular lines, but that region is variegated with con- 

 spicuous pale gray marks. On the front of the 5th, 6th, 7th, 8th, and 9th segments 

 is a very conspicuous brick-red transverse mark ; the spiracles and trapezoidal dots 

 are distinct, black. The ventral surface is dull smoke colour, with interrupted grey 

 central stripe ; legs pale yellowish-brown ban-ed with black, prolegs pinkish-purple. 



Yar. 2 has the ground colour bright green, and the head reddish-brown. Medio- 

 dorsal line indistinct, yellowish-gi-ey, edged on the 2nd, 3rd, and 4th, and again on 

 the lOtli, 11th, and 12tli segments, with a dark green line ; sub-dorsal lines more 

 distinct, yellowish-grey ; there are no perceptible spiracular lines, that region being 

 variegated witli yellowish-green ; the anal segment is of the same colour as the head, 

 reddish-brown, but has in addition a yellow streak outside each clasper ; spiracles 

 and usual dots very minute, black ; the segmental divisions yellow. The ventral 

 surface is green with interrupted paler central stripe ; the legs and prolegs reddish- 

 brown. The moths from both varieties have appeared during the present month.

Entomological Society of London, 2nd June, 1873. — Sir Sidney Smith 

 Satjndebs, Vice-President, in the Chair. 



Mr. Bond exhibited living specimens of a species of Bruchus, bred from seeds 

 of Oleditsehia sinensis (received from Japan), which they had destroyed to such au 

 extent as to render it doubtful if any remained sound.
