larvse of Caradrina amhigua, an insect which had recently occurred in England in 

 countless numbers. They were bred from ova laid by a female taken on the South 

 Devon coast, and fed indiscriminately on low plants. Mr. M. Burr read a paper 

 supplementary to Mr. Q-reen's previous communication on Dyscritina, and definitely 

 referred the imagos to the genus Diplatys, D . longisetosa, Westw., being a good 

 species, and Mr. Green's new form proving to be D. nigrioeps, Kirby. Dr. Chapman 

 communicated a paper on the larva of Eriocephala Allionella, which he stated to be 

 essentially similar to that of E. calthella, previously described by him. — W. F. H.

The major divisions of PsycJioda, established ante, 2nd ser., vol.

 op. cit., p. 129, illustrated in vol. v, pi. iv, Ps. 1 — 6, are here adapted 

 for wider application. 



Affinities nearest with Pericoma, Section III, if judged according 

 to the distribution of the bristling hair of the wings ; but in certain 

 features of the neuration an approach is made to the 4th and 5th 

 Sections of that genus, as may partly be inferred from the tabulation 

 cited, and comparison of the figures. Maruina, because of the form 

 of the male genitalia, is here scheduled as an additional Section of 

 Psychoda, on the assumption that the neuration towards the base of 

 the wing was inaccurately represented by Miiller, and will be found 

 conformable in its main features to that of Psychoda. Figures of 

 densely hairy, undenuded wings in situ, have invariably overtaxed 

 the ability of artists to illustrate with exactitude the details of neura- 

 tion near the wing-roots ; and in this particular the most recently 

 published figures of Psychod(s are as worthless in critical value as 

 those of Leeuwenhoek and Frisch, cited by Linne and De Geer. 



Males of Psychoda (probably immature), with stunted antennae 

 are frequently met with : the beaks of joints in the flagellum not 

 having attained their full length, cause the verticils of long hair to be
