UraniscodoH plica — he did not know the local name. The 

 portion of the text of the article which was supposed to apply 

 to the picture had reference to another lizard altogether, viz., 

 the Foh/ehriis marmoratvH which they had also sent to the 

 Society later in the year. — Mr, Carr said the local name for the 

 Plica lizard was " Old Man" (laughter). — Mr. Potter exhibited 

 a curious hairy Bomhi/x caterpillar found at St. Ann's, a speci- 

 men of the Casfnid licus — local name : Cane sucker — a moth, bred 

 by him from the larva which he said lives in the trunk of the 

 banana plant and completely destroys it. He also showed a 

 caterpillar belonging to the family of Psychidae, which carry 

 about sacks made up of little pieces of wood and sticks in which 

 they are transformed into pupa?, — Dr. Rake said that as the 

 question of the so called Mosquito Worm had again cropped up 

 he thought a letter he had received upon the subject, four years 

 ago, would be interesting to the Club. A friend of his about 

 that time went to Venezuela and while there he got a swelling 

 in the cheek. He came back here and he (Dr. Rake) treated 

 him. The swelling burst and one of these vyorms came out. 

 He (the speaker) put it into spirits and sent it to the British 

 Museum. He received this reply : —

My dear Sir, — The larva you send is undoubtedly that of a 

 S'pecies of Derm at obi a, I will not venture to say that it is D. 

 noci'ialis although that is possible. Your specimen agrees very well 

 with the figure given by Grube (Arch.f. Naturgeschichte 1860 1. 1 f. 

 4) and Grube considered his distinct from iioxialis. It is however 

 a difficult question to settle as the figure given of noxialis in the 

 Ann. d. Sci. Nat. 1845 t. 4a. f. 5, is not a good one, and so the 

 differences may be due to bad drawing and the original may 

 belong to the same species. Tlie question then stands thus : 

 your larva is the one /rHo«'H under the name D(^;-wa/o/>/(/ noxiali)>, 

 but there is not at present sufficient evidence to prove that it is 

 the same insect as Avas origiHolhj described under the name 

 noxialis. 



I am, dear Sir, 



Yours faithfully, 



Chas. O. Watehholsk.
