light drab or greyish buflf to bright green, all hues intermediate being met 

 with. But curiously enough the larvae, as far as I have observed, are 

 always uniform, both in respect of markings and coloration. The year 

 before last I commenced operations rather later than usual, and only found 

 sixteen larvae. These, however, were all met with within the space of one 

 week (July 5th onwards). As they were all full-fed, I had not long to wait 

 for the pupae. Of the chrysalids resulting, only one out of eight obtained 

 was of the green variety. The caterpillars of A. euphenoides feed quite 

 exposed, sometimes as many as five on one plant, on the flowers and seed- 

 vessels ; the leaves they never appear to touch. This season, though I 

 collected a far larger number of larvae than usual, not one pupa was of this 

 green variety, though some of the chrysalids were of a decidedly greenish 

 hue. Possibly this may result from one of two things ; either the devia- 

 tion from the common form is due to an unusually mild summer-like 

 winter, or, perhaps, the pupae vary to suit the exigencies of circumstances 

 in certain localities. I think, on the whole, however, the latter supposition 

 is the more probable. UnUke the green chrysalids of Papilio machaon, 

 which some entomologists assert occur only in the summer brood, both 

 varieties of the pupae of A. euphenoides pass the winter. Nor is the 

 difference of colour apparently confined to any one sex. For instance, two 

 years ago, I obtained several males and females from grey pupae, and a 

 male example besides from a green pupa. I have never noticed any 

 departure from the typical form in the chrysalids of A. helia, Cr., which 

 are met with at the same time as A. euphenoides, in the proportion of about 

 ten to fifty (or one-fifth) of the latter, in the locality of which I write. It 

 is interesting to note, from previous seasons, that imagines from these 

 green pupae (as far as I have noticed) differ in no way from those obtained 

 from normal chrysaUds. Possibly these facts may have some bearing on the 

 old P. machaon pupa discussion (see Entom. xxv. 44, 93, 120). Perhaps 

 other collectors would give the results of their observations on the pupae of 

 other (variable) species ? — Fkank Bromilow; St. Maurice, Nice, S. France,

SOCIETIES. 



Entomological Society of London. — February 22nd, 1893. — Heury 

 John Elwes, Esq., F.L.S., F.Z.S., President, in the chair. Mr. Kenneth 

 J. Morton, of Glenview Cottage, Carluke, N.B. ; Herr A. F. Nonfried, of 

 Rakovnik, Bohemia; and Mr. Charles C. Taylor, of Rae Town, Kingston, 

 Jamaica, were elected Fellows of the Society. Mr. F. J. Hanbury 

 exhibited, on behalf of Mr. Percy H. Russ, of Sligo, several long and very 

 variable series of Agrotis tritici, A. valligera and A. cursoria, together with 

 Irish forms of many other species, some of which were believed to be new 

 to Ireland. Mr. W. H. B. Fletcher and Mr. J. W. Tutt made some 

 remarks on the species. Mr. R. W. L^d exhibited specimens of a species 

 of Acarus found in New Zealand wheat. He stated that Mr. A. D. 

 Michael had examined the specimens, and pronounced them to belong to 

 Tyroglyphus farince, a species which bad been known for over a hundred 

 years as a destroyer of corn, and was only too abundant all over Europe, 

 and probably over the temperate regions of the world. Dr. T. A. Chapman 

 exhibited, by means of the oxy-hydrogeu lantern, photographs of the larva
