tab. 221) witb those of the two insects just mentioned, and he can scarcely fail to come 

 to the conclusion that it also belongs to the same family, although it has recently 

 been placed with the Glottulidas, to which it certainly has considerable affinity. 

 Several other insects among the ChelonidEe in the British Museum — such as Anaphela 

 luctifera ; possibly the genus Ovios ; and Phsegorista, Massaga and Rhosus among 

 the Pericopidae — will probably eventually be classed wiih the Agaristidse. Two new 

 species described by Mr. Walker in the genus Melanchroia appear likewise to belong 

 to .this family, and also Josia Noclilux, J. coniiuua and J. separata, which, though 

 they have somewhat similar colouring, entirely depart from the typical structure of the 

 MelameridiE. In the family just mentioned, as arranged at the British Museum, 

 Dioptis hesperoides would also appear to belong to the Agaristidse ; and the entire 

 genus Dioptis seems to want revision, having apparently little in common but the 

 style of colouring. The group Agyrta, including Micilia, Dux, &c., have two pairs 

 of well-developed spurs to the hind tibiae, with the venation of Ctenucha and the 

 latter genera of the Euchromidte, with which they should probably be associated. D. 

 vinosa, D, Ergolis, &c., have one pair of minute spurs to the hind tibise, with venation 

 approaching the Pericopidse, and should probably be placed in that family ; while 

 D. glaucopis, D. sobria and D. umbrifera possess the structure of Josia monilis, &c., 

 and belong unquestionably to that genus. It is much to be desired that some ento- 

 mologist visiting South America would seek to verity Stoll's figures of the trans- 

 formations of Dioptis Micilia and D. coelestina. It seems scarcely possible to suppose 

 that some error has not taken place with regard to these insects and the two species of 

 Melanchroia which be tigures on the same plate, both the larvae and cocoons resemble 

 so closely those of the Limacodidae, and the two pupae seem much too robust for such 

 delicate insects as D. Micilia and D. coelestina. — jR. F. Logan ; Duddingston, Edin-

Occurrence of Lilhosia caniola of Hubner in Devonshire and in Ireland. — Mr. 

 King, of Torquay, called upon me a few weeks since with some insects collected in 

 Devonshire and Cornwall, from which I picked out a worn specimen of a Lithosia 

 which appeared distinct from any recorded British species : I believe it to be 

 L. caniola of Hiibuer, &c , — a species not uncommon in France, and very likely to 

 occur here. Mr. Barrett took four specimens of the same species in Ireland last 

 August, one of which he kindly sent me to examine. Although in much better con- 

 dition than the one which I have, it is not fine ; but I think there can be little doubt 

 of its being L. caniola, a species likely to be overlooked from its dull colour, which 

 would lead many to consider it one of the common species in faded condition. My 

 friend M. Guenee, who has had all my Lithosiae for examination, has just sent a paper 

 upon the European species of the genus Lithosia for publication in the 'Transactions' 

 of the Entomological Society of France : as soon as it appears I will send a few 

 remarks upon the British species for insertion in the ' Zoologist.' — Henry Doubleday ;

Description of I he Larva of Hemerophila ahruplaria. — Ground-colour pale grayish 

 or greenish drab. Segmental divisions pink. Down the centre of the back a series of 

 purplish blotches, becoming confluent on the anterior and posterior segments, on the 

 latter almost evanescent. Back, belly and anal plate sparingly spotted with black. 

 Immediately preceding the latter a black belt encircling the whole body. In the 

 centre of each ventral segment some spiracle-like spots. Belly greenish. Spiracular 

 lines dusky. The body tapering gradually towards the head. Capital segments
