134 Dr. T. A. Chapman's Observations on 



several eggs from Mr. Bankes, laid by females captured at 

 Wareham, Dorset. I find from my notes that a $ taken 

 AuGfUst 20th laid e^s^s from which two larvas hatched on 

 August 30th ; and from a female captured August 23rd 

 two larvse hatched on September 6th. A further supply 

 of eggs were received on August 31st. The first larvjB 

 that hatched were placed on all sorts of bog plants ob- 

 tainable near Reigate, but without result, and when these 

 were finally jalaced on the Droscra plants sent by Mr. 

 Bankes, they were already rather exhausted. 



It was on August 31st that the plants of Z^rosera arrived, 

 along with 16 eggs on the same date. 



These eggs were loose, two on leno and the rest on a 

 flower-stalk, or rather fruit-head of Droscra. Three of the 

 original larvse survived, and though obviously exhausted, 

 seemed more at home on the Droscra than on anything 

 yet tried. One placed on a leaf was, however, in process 

 of digestion next morning. The others had disappeared 

 somewhere, apparently in the heart of the little plants. 

 When the new set of eggs began to hatch after a few days, 

 September 6th, much time was spent in watching the 

 young larva3 on the plants ; none were placed amongst the 

 glands on the leaves, but the largest of the unexpanded 

 leaves was selected. They eventually got down towards 

 the centre of the plant and became much more quiet and 

 sluggish there, but still on the move. The next day none 

 of them could be found. 



Sept. 14th. Looked at occasionally, nothing could be 

 made of the Droscra plants, but to-day a careful examin- 

 ation shows a small pile of frass near the centre in two 

 of the plants. Another shows nothing, and in the fourth 

 is a living larva of paludum, a little grown, but out, ex- 

 posed, and looking sluggish. A curious point is that of 

 the August 30 eggs ; those separate, and one on the muslin, 

 hatched, the others on the muslin proved infertile and did 

 not change colour. These hatched September 6th, the 

 eggs on the seed-stem are still (Itfcth) unhatched, they 

 changed colour a day or two later than the others, and 

 their hatching was expected about the 8th, but they make 

 no sign. The young larvce inside have, since that date, 

 been obviously mature. These ultimately proved to be 

 dead. The eggs remain free from shrinking, mould, or 

 other sign of death or decay, and give the impression of 

 intending^ hibernation.
