22 THE ENTOMOLOGIST. 



which is the only true specimen I have seen ; it is unfor- 

 tunately injured ; three lasiophthalmus and one Umbellatarum, 

 both difficult species to find; about eight cinctellus; one spe- 

 cimen called decorus, which is, however, only a variety of 

 auricollis. 



Melanostoma. All four British species are here, there 

 beinj^ the two types, both females, of Walker's concolor, 

 which is only arabigua of Fallen ; two hyalinata, which I 

 believe is only rare because caught late in the year; and 

 several mellina and scalaris. There are two female specimens 

 belonging about here which puzzle me very much ; there is 

 a somewhat similar female in the British Museum, and 1 

 possess one myself: they are peculiar from their long sharply 

 pointed abdomen, which generally has a couple of red spots : 

 1 am not at all sure of their genus. 



Platychirus. All the British species are here except im- 

 marginatus, but the only specimens worth notice are a pair of 

 probably fulviventris of Macquart, a species perhaps over- 

 looked in England. 



Pyropla3na. There are plenty of both species. 



Chilosia. The collection is very rich in species, but not in 

 specimens in this genus ; amongst others it contains one male 

 intonsa, four pigra (one male, three females) ; the type of 

 Walker's nigrina, which is only the male of variabilis ; one 

 female impressa ; about four pairs of albitarsis, one male mu- 

 labilis (?) ; three males and two females of flavicornis ; grossa, 

 the male of which 1 expect is Walker's chrysocoma, as there 

 are none of that species in the collection ; five chloris ; one 

 female decidua ; one female praecox; one female Soror, from 

 which I suppose Walker described his scutellata, as he says 

 "antenna? bright ferruginous;" a pair of sparsa; two female 

 antiqua ; a pair of maculata, a most remarkable species ; and 

 two specimens which I cannot recognise. 



Brachyopa. There are only two bicolor. 



Leucozona. There is a full row of Lucorum, as well as of 

 Chrysochlamys cuprea. 



Rhingia. Both species of Ilhingia seem to be here, and 

 ti^lerably distinct, there being seven of the pale rostrata and 

 a lot of the dark camjiestris. 



Volucella. All the four species are well represented, and 

 there were a couple of V. zonaiia, reporled to have been
