boldly attack and devour all the V. verriculata larvae they come across. 

 , Further information on the above two species will be given in future con- 

 tributions. Cermatulus nasalis has also been found attacking the larvae. 



The Cocoon. 



The cocoon is thin and scanty, and is composed of a rather coarse brown 

 silk, which is extremely viscid. When viewed through the microscope the 

 individual threads are bespangled at regular intervals with globules of 

 sticky matter, very similar to the web of a spider. Favourite places for 

 spinning are at the base of the leaves up against the trunk of the tree, in 

 the crevices of the bark, and amongst the dead leaves hanging around the 

 stem. 



The Pupa. 



Immediately after the last moult the wings, head, and limbs of the pupa 

 are green ; the anal segments are light pink, with a strong reddish medio- 

 dorsal stripe ; the prothorax is pink or rather reddish, and at the juncture 

 of the segments the pink coloration is very marked. Within twenty-four 

 hours the pupa passes through several shades of brown till it is very dark, 



almost black ; the intersegmental membrane 

 between the movable segments is much lighter 

 in colour. The frontal headpiece has three 

 slight prominences, one on either side at the 

 base of the antennae, the 3rd ventral, above 

 the labrum. The thoracic segments bear no 

 very marked dorsal hump, while the abdomen 

 is inclined to be short and stout. Abdominals

view, a, prothorax ; is short and stumpy, bearing 4 whorled 

 b, 1st spiracle ; c, an- hooks, two on either side, and slightlv dorsal, 

 tenna ; d, epicranium ; ]) orm i v j ew - The head is slightly depressed 

 e ' eye ' between the antennae, and not visible. The 



prothorax is narrow, with a central suture, and is somewhat pitted and 

 wrinkled. The 1st spiracle has a long narrow opening, and is very con- 

 spicuous. Both the meso- and meta-thorax bear a strong central suture, 

 and are wrinkled. The abdominal segments are strongly pitted, and bear 

 minute hairs that correspond in position with the larval tubercles, but are 

 verv hard to distinguish. There is no trace of subsegmentation. The 5th, 

 6th, and subsequent abdominal segments are swollen anteriorly ; this is 

 very marked on the sides and dorsum. The hindwings show a very narrow 

 strip, widest at the 1st abdominal, rapidly narrowing in the 2nd, and again 

 widening slightly in the 3rd and 4th abdominals. Lateral view : The apex 

 of the head is in front of the axial line. There is a deep depression in the 

 maxillae some little distance from their origin ; from this depression they 

 slope outwards to their extremities near the posterior margin of the 4th 

 abdominal segment ; from here the abdominals taper uniformly and rapidly 

 to the cremaster. The whole length of the antenna is visible, the base being 

 level with the top of the eye ; it rapidly widens out till on a line with the 

 bottom of the eye, and then gradually narrows towards the tip ; every 

 joint is plainly visible. A very slight margin of the hindwing can be seen 

 at the 1st and 4th abdominals. In the forewing Poulton's line is absent, 

 though slight venation can be distinguished. The spiracles are very pro- 

 minent on raised bases, and are dorso-lateral, oval. Ventral view :■ The
