9750 Insects. 



that they could not all have been from one brood. On the 22nd of 

 July 1 collected a considerable number for the purpose of describing 

 and figuring them, and intending, if possible, to rear them. It hap- 

 pened that a couple of days afier 1 also received a good number, 

 which Mr. B. Wtlewaall had found in Mr. Hartevelt's garden, on Rosa 

 poraifera, and which he sent to me for rearing. 



The length of the largest individuals was 2 centimetres, as repre- 

 sented at fig. 3 in our plate. The head was shiuing orange, the eyes 

 black and circular, set in two round black spots. At the top of the 

 clypeus were two brown spots like inverted commas. The jaws were 

 orange, with the apices brown ; the antennae, which were below the 

 eyes, were very small, annulated with a somewhat darker tint, the lips 

 orange. On the head were some minute punctuations and little gray 

 hairs. Some were destitute of the comma-like spots ; in others these 

 spots were much enlarged, almost forming a crescent. 



The larvae of the genus Hylotoma are generally stated to have 

 eighteen legs: on very close examination I found my larvae had three 

 pairs of thoracic legs, six pairs of abdominal legs, and two almost 

 confluent anal legs ; the sixth pair of abdominal legs were, however, 

 remarkably small, and appeared as if they could be wholly withdrawn 

 under the skin. 



The thoracic legs were obscure green, with a black spot on the 

 upper side of the base ; they were armed at the end with a brown 

 claw, below which was a little round bladder. Fig. 4 represents the 

 head, together with the first segment and one thoracic leg in profile. 

 The other legs were pale obscure green, with a Utile black spot just 

 above the base. 



The whole creature was very glossy and of a greenish gray tint ; the 

 back was orange from the second to the eleventh segment, the first 

 and twelfth being greenish ; but above the anus, on the last segment, 

 the colour was orange. In the folds dividing the orange-coloured 

 segments on the back the skin was green. On either side of the body, 

 just above the legs, was a row of eleven large black knobs, each bearing 

 a certain number of little short hairs. On the upper surface of each 

 segment were two rows consisting of six pretty large black spots and 

 a few smaller ones, on each of which was a single hair (see fig. 5). 

 The stigmata were small, margined with white, with a small horny spot 

 on either side. Above the anus on the last segment was a row of four 

 small spots, and below this a very large black spot, as shown at 

 fig. 6. 



It appeared to me at the time a singular circumstance that the
