136 THE entomologist's record. 



mentioned as distinctive to ova, and this is not the only case that has 

 come under my observation. An ovum of Cerura vinula, taken last 

 year, also produced an ichneumon tiy. I presume these flies were of 

 different species. The larvae of the former passed the whole winter 

 within the egg, whereas the latter came out in some six weeks or two 

 months, and, indeed, I think the one from C. vinula was larger. The 

 others I still have in a box. If you care to see them, I can forward 

 them, though they are very small and shrivelled. — C. Bingham

Pupa of Melit^a aurinia. — I have often wondered how Hellins 

 figured such a dark pupa of M. aurinia (Larvae of Brit. Butts., pi. xii., 

 fig. 2a), but I observe that for some hours previous to emergence the 

 pupa turns to a purplish hue. No doubt Hellins' drawing was made 

 from a pupa in this stage. — J. W. Tutt, Westcombe Hill, S.E. 



A NEW MODE OF SEPARATING THE FKJIALES OF P0LYOMMATU8 BELLARGUS 



AND P. cniiYDON. — In addition to the differences enumerated as existing 

 between these species ante, p. 50), I should like to point out the 

 following difference, which I think has not yet been noted. If 

 the undersides of these species be examined carefully, side by side, it 

 will be observed that the dark crescent-shaped markings on the under- 

 sides of the anterior wings of Poljioinmatus corydon and P. bellaryus 

 constitute a sure and easy method of differentiating the females of 

 these two species. In P. beUarnxis the markings lie very evenly in the 

 venule spaces, whether their convex sides are acute or otherwise, and 

 the axes of these crescents all converge towards the base of the wings. 

 Now, in P. conjdon there are two distinct sets of markings. Three 

 within the spaces of the sub-costal and discal venules being quite 

 different from the three in the spaces of the median venules. In the 

 former case the crescents are more or less acute, and their axes 

 tend downwards and inwards. In the latter case, and here comes 

 the most pronounced character, the markings are frequently oblong, 

 extending obli(]uely inwards and upwards. Where they retain a more 

 or less crescent form, their axes, that is, lines passing through their 

 most convex part, still pass inwards and upwards. I have examined 

 many specimens, but I have seen none that I have not been able to 

 at once identify on these lines. — H. Tunaley, F.E.S., 30, Fairmount

OviposiTioN OF Trochiliuji BEiMBEciFORME. — Aslhavenotediii previous 

 years, I continue each year to find the eggs of this species laid on the 

 undersides of the leaves of osiers, where the species is common, so 

 that there can be little doubt that this is not a mere occasional vagary, 

 but the normal method of oviposition in this species. The young- 

 larva must have several feet to travel to reach the usual habitat of 

 the larva ; but by travelling downwards it must inevitably meet with 

 wood of a proper age. Possibly the young larva enters younger wood 

 than we usually credit it with. I enclose you some leaves with ova.—

Is MiNOA MURINATA (eUPHORBIATa) DOUBLE-BROODED ? (ScC EnT. 



Rec, ,hme, 1896, p. 84). — As a fact, in connection with the above 

 question, I may state that on the 4th of August, 1893, I took a 

 specimen of this moth, evidently only just out of the pupal state ; it is 

 not rare here in most seasons during May. In the year 1893 it was 

 out in April, earlier than I had ever before noticed it. — 0. P. Cam- 

 bridge, M.A., F.E.S., Bloxworth Rectory. June 16?/(, 1896.
