I iiiiicli regret. A few details, noted down at the time, are perhaps 

 better than iiothiiig ; but the larvae of all Chrysopids are most 

 difficult to describe iu such a way as to give any real idea of them. 



The length of the larvae at the second change is 5 mm. When 

 fully grown they increase to about 8 mm. 



In the last skin the 

 head is shining whitish. 

 Characteristic markings and 

 eyes very dai'k brown, al- 

 most black, a dark line 

 running through the eyes. 

 Sucking spears, pale mad- 

 der-brown, crimson at the 

 tips. Palpi transparent 

 whitish shading to mad- 

 der at the tips. Legs 

 transparent whitish. Tarsi 

 brownish, ringed with dark 

 fuscous, knees brown. Tho- 

 rax whitish - yellow, with 

 dark madder markings. A 

 large wart at the angle of 

 each segment from which 

 springs from 6 — 9 black hairs. Ahdome^i pale green with dark madder- markings. 

 The first six segments have warts at the sides, whitish, with 5 — 10 long black 

 and white hairs mixed. Two second middle rows of smaller warts run down 

 the back of these segments, one on each side of the dividing line, and pale 

 greenish in colour. The central line is dark madder and runs down the whole 

 length of the back, from the prothorax to the tail. The underneath parts are 

 pale green, fading to whitish at the sides, which shows up as a conspicuous 

 white line against the dark upper parts when the larva is viewed sideways. 

 Two broad madder stripes run down the underneath part of the abdomen. 



The cocoons were spun in the folds of a leaf or in any convenient 

 place. They measure about 4 mm. in length, and are longer than 

 broad. They do not differ from the ordinary Chrysopid pattern. 

 Emergence takes pl^ce from the apex, the cocoons opening by means 

 of a small lid. The pupal covering is cast very quickly, the imago 

 escaping by a slit in the thorax. In all cases where emergence took 

 place successfully, it did not occur until the following spring. 



The accompanying table gives the complete dates of the life- 

 history of two of the larvse. The first one completed its lai-val 

 existence in a fortnight, owing to the high temperature prevailing at 

 the time ; the second, hatching later, took almost twice as long.
