120 VARIETIES. 



hatching than those of A. Chclidonii, as recorded by Reaumur, 

 for not a tenth of them had produced the scale-like larvae when 

 I examined the trees nearly a month later. Having left that 

 part of the country soon after, I did not ascertain whether there 

 is more than one brood in the year. The perfect insect 

 measures about \\ line across the wings expanded; the body is 

 pale yellow, but the head, thorax, antennae and legs covered 

 with white powder ; the tip of the sucker dusky, the eyes 

 black ; the hinder segments of the abdomen above, and the 

 borer of the female, are greyish. The wings pearly-white, and 

 covered with white powder : in old specimens only there is a 

 duller reflection in the usual places near the base and end of 

 the principal nervure ; but even there it is very obscure, and 

 disappears if the light is dispersed by a lens of moderate 

 power. a

1 2. Insects attracted by the offensive Smell of a Flower. — 

 In July 1832, I had four very luxuriant blossoms on a plant 

 of Arum Dracimcidus, the Dragon Arum, the smell of which 

 is, perhaps, the most offensive of any plant with which we are 

 acquainted; in the present instance, it was so much so as 

 to attract numbers of those insects whose food consists of 

 putrid substances ; these must certainly have been deceived 

 by the scent, which they mistook for that of their natural 

 food, for in no instance did they eat any part of the 

 flower, but, falling down the smooth sides of the corolla, slipt 

 into the cup, and there perished. On examining the cups 

 after the flowers had faded, they contained the following 

 insects : — Staphylinus maxillosus, Philonthus, six species ; 

 Hister, three species ; Nitidula bipunctata, grisea, and two 

 others ; Scatophaga, three species ; Musca vomitoria, Caesar, 

 thalassina, Lanio, maculata, and three others ; Anthomyia 

 lardaria ; and Helophorus griseus.

a I examined Chelidonium majus in several gardens of the neighbourhood, but 

 did not meet with Al. Chelidonii. The other, flying round the Phillyrea trees, 

 lights on the passers by and on the neighbouring shrubs, but I did not find 

 either egg or puparium on trees of any other genus.
