kept a certain number of the larva? tliat had tliis hkck lilotch under 

 observation, and found " tlic same or^an, a httle modiiied but 

 sufficiently reeogni/.aldo, in tlie pupa and in tlie imago, where the two 

 reniform bodies had l)eeonie united into a single ovoid body. In the 

 latter, tlie pigmented body was connected by two long ducts with the 

 genital armature." It was found that the larva? with the black 

 blotches produced exclusively male imagines, so that the writer 

 concludes that the organ he had been observing was a testicle in course 

 of formation. Another striking fact was, that, though all the other 

 organs of the larva underwent complete histolysis in the pupa, the 

 testicle formed in the body of the larva continued its develoj)ment in 

 the pupa without undergoing histolysis. 



The liev. W. C. Hey, M.A., of York, records (Naturalixf, July) the 

 recent capture in that city, by his nephew, Mr. Gilbert Hudson, of 

 several specimens of the scarce beetle, Oct/ptts pedntor, which has 

 hitherto only been recorded from the extreme south of England. 



Mr. F. J. Bridge, of Exeter College, reports (Entom., July), that 

 his father captured a specimen of Deilephila livornicci, on June 2nd, 

 about 8.30 jj.m., in his garden at Egg Buckland, near Plymouth.

OTES ON COLLECTING, Etc. 



Tjarvae of Vanessa urtic^ in Yorkshire. — The larvae of this 

 species simply swarm in this part of Yorkshire at present. I have 

 never seen anything like it before. — W. C. Gribble, Springfield, 

 Stokeley. June Uth, 1895. 



Food-plants of Gortyna ochracea. — What a number of different 

 food-plants this species has I A few evenings ago, when looking for 

 EnpoecUia implicitana a short distance from here, I noticed some tall 

 rank stems of the common yarrow, one or two of which liad " f rass " 

 sticking to the upper part. Thinking that I had come across the larva 

 of PIdfi/ptilia hertraiui (a species which I had not seen in the larval 

 stage), I opened the stems, only, howevei*, to find a half-grown larva of 

 G. ochracea inside. In addition to this (to me) new food-plant, I have 

 at various times found the larvae feeding in the following: — Cardmis 

 pxdmtris, Eapatorium cannahinum, Artemisia vulgaris, Arctium lappa, 

 Digitalis purpurea, Samhucus nigra (in young soft stems), Scrophnlaria 

 aquatica, and on one occasion in potato stems — truly as varied a diet as 

 any larva need wish for. — A. Thurnall, 144, Chobham Eoad, Stratford 

 New Town, E. June IQth, 1895. 



Wild Hop a Food-plant of Vanessa io. — On June 26th, 1895, T 

 found a brood of larvae of Vanessa io at Kersey, Suffolk, on wild hop ; 

 they were nearly full-grown, and have now, in fact, all spun up. 

 Though the wild hop, which was growing on a hedge, was twisting 

 and twining in and about quantities of nettles, not a single larva was 

 found on the nettles. I do not find this food-plant mentioned in any 

 of my books. — F. Le Gkice (Col.). 4, Shorncliffe Koad, Folkestone. 

 June 'dOth, 1895. 



Tlusia moneta at Bromley. — I bred yesterday a very fine specimen 



of this moth from a larva found on monkshood in my garden here.
