166 THE ENTOMOLOGIST. 



eye at half a dozen yards' distance, I cannot distinguish L. conspicua 

 yet even with the aid of a microscope. 



L. strigom, Meig. I have never seen any British specimens at all 

 like this, 



L. sp. ? One or two large species of Leptis occur in Britain which 

 have no yellowish markings. I want to see more of them. 



L. annidata, De G. I have never seen this from Britain. 



Syniphoromyia melana, Meig. 



Sp)ania nifjra, Meig. (female). 



Xylofhagus cinctus, De G. 



Hamatopota italica, Meig. (male). The species probably occurs 

 freely at the mouth of the Thames Valley. 



Tabanus ylaiicopis, Meig. (male). 



Chrysops sepulcralis, Fabr. 



Anthrax. Any clear- winged species except A. paniscua. I believe 

 at least three others occur in Britain. 



Bomhylius. Any clear-winged species. 



Psilocephala ardea, Fabr. 



Oncodes pallipes, Latr., and 0. varius, Latr. 



Dioctria linearis, Fabr., as distinguished from D. flavipes, Meig. 



Asilus. Several species unknown to me ought to occur in Britain 

 belonging to the old genus Asilus, especially such as Antipaliis varipes, 

 Meig., Neoitamus socius, Lw., Dysmachns sp. ?, &c. 



Eutohnus riifiharhis, Meig. 



Scenopiyim nlyer, De G., and S. glabrifrous, Meig. (male). 



Or anything else apparently unrecorded as British in the above 

 families. — G. H. Verrall ; Sussex Lodge, Newmarket, May, 1904. 



Winter Treatment of Pup.e. — It might be interesting to others, 

 as well as myself, if we could have a short discussion on the best 

 method of keeping pupae through the winter. The Kev. J. Greene, in 

 his very practical book, mentions that he never " damps " his pupae, 

 and certainly I know personally that he has been very successful in 

 rearing them. On the other hand, other entomological luminaries 

 give elaborate directions for " damping " pupte. and presumably are 

 successful also. And to come to my own small experiences, I have 

 found that if I keep pup» without moisture they as a rule dry up, so 

 that not one in ten emerges ; while if I damp them a larger propor- 

 tion emerge, but a good many grow mouldy. It seems reasonable to 

 suppose that some moisture would be beneficial, but probably the mode 

 of application is the difficulty. As I hope that others will give their 

 experiences, may I begin with one of my own ? I once had a brood 

 of forty Tceniocanipa opima, which I reared in two very large flower- 

 pots half full of earth, into which in due course they retired and 

 pupated in autumn. I left them strictly untouched, but once a month 

 I gave the earth a good soaking from a watering-pot, and in the end 

 the whole forty emerged, without a single cripple or failure of any 

 sort. Now, I should like to combine this question with that of 

 " forcing." And what I wish to know about this is : is forcing likely 

 to be successful with all pupas, or are there some to which it is simply 

 destructive? Again, I should like to narrate the system I have been 

 trying during the past winter. I took a large wooden box and balanced
