400 [October, 



Time of appearance of Chauliodus insecurellus. — There can be little doubt, I 

 think, that this species is double-brooded in Britain, as mentioned by Mr. Warren 

 (Ent. Mo. Mag., xxiv, p. 144). Mr. Meyrick's specimens were captured in June 

 (Ent. Mo. Mag., ante, p. 361), and I took specimens myself on Freshwater Downs, 

 Isle of Wight, during the first week of the present month (August). — J. W. Tctt, 

 Westcombe Park, S.E. : August 22nd, 1889. 



Crabro leucostoma, L. : its Nidijication, and two Parasites. — In March, 1885, 

 I fell in with a willow that had been split from top almost to bottom, the smaller 

 portion of which was bent downward till its top almost touched the grass. In the 

 exposed wood near the head of this part were a number of cocoons crowded to- 

 gether within a small space. A small piece, some three and half inches diameter, of 

 this wood I took home, and bred therefrom in May and June twenty-seven specimens 

 of Crabro leucostoma, one Tryphon signator, and one small Tachinid. The last I 

 have just tried to obtain the name of, but without success. 



Wishing to ascertain what connection, if any, existed between the Crabro and 

 the other insects, I carefully picked to bits the wood, finding twenty -nine vacated 

 cocoons, three containing dead pupae, and three cells provisioned with a species of 

 Dolichopodidce (in colour resembling Dolichopus atratus, but smaller), dry and too 

 brittle to disentangle, which had not been at all fed upon. 



Twenty-seven of the vacated cocoons were roughly broken off at the head end, 

 at about one-fourth of their length — corresponding in number with the Crabros 

 bred ; while two were perforated, one near the head end, the other at the opposite 

 extremity. The latter cocoons were carded and preserved, and I have just cut them 

 open with fine scissors : the result being that the one perforated at the tail end con- 

 tained the exuviae of an Ichneumon, the Tryphon, the one perforated at the head end 

 the very thin and collapsed puparium of the Tachinid. 



I have several times bred species of Tachinidcs, and found that, whilst most 

 species pupated in the earth, others pupated in the puparia, or even pupae, of their 

 victims. 



Several of the Crabro cocoons were so close to the exposed surface of the wood, 

 and the wood was so easily penetrable, that there could have been no extraordinary 

 obstacle to oviposition by either parasite. —J. E. Fletcher, Worcester : August, 1889. 



Gnorimus variabilis, L., in Windsor Forest. — In my work on British Coleoptera, 

 Part xxxi, p. 59, I stated, as I believed to be the fact, that Gnorimus variabilis had 

 not occurred in the above locality for many years past ; I have lately received the 

 following communication from Mr. J. C. Bowring, of Forest Farm, Windsor Forest, 

 which will probably be very interesting to many British Coleopterists, as showing 

 that some of our rarer species are probably by no means extinct, but only overlooked : 



" It may interest you to learn that many specimens have been taken here by 

 myself and my boys during the last few years, and that last year no less than nine 

 (two males and seven females) were found on one oak tree in our grounds. It is 

 curious that among all the specimens taken during the last six years only two males 

 have been captured. 



" A fine specimen of Gnorimus nobilis was taken by one of my sons at Woolwich, 

 under some lime trees, in June last.
