24 THE ENTOMOLOGIST. 



ine like immature faded Coemeteriorum, onlv the head seems 

 broader than in that species. 



Pipiza. In this genus there are twelve female noctiluca, 

 of which I expect vana is the male ; vana is labelled here 

 partly as bimaculata' and partly as lugubris ; there are two 

 males and one female true lugubris ; two females called 

 nolata, one of which has slightly clouded wings, and the 

 other has the abdominal spots small ; two females called 

 guttata, one of which belongs elsewhere ; one very immature 

 specimen, from which Walker described vitrea ; quadriguttata 

 and quadrimaculata are probably the same and very likely 

 only varieties of noctiluca, male. 



Cnemodon. The three males and two females labelled 

 vitripennis probably belong to this genus, and are most likely 

 acuminata. 



Pipizella. There are several virens; three female bigut- 

 tata, called flavitarsis, to which very likely the two males 

 called melancholica belong. 



Paragus. Nine specimens, which I have not examined, are 

 in the collection. 



Chrysotoxnm. There is nearly all the genus here, there 

 being six species, including half-a-dozen vernale, not dis- 

 tinguished from festivum in England till separated by Mr. 

 Newman; four fine specimens of elegans and one of oclo- 

 maculatum. 



Callicera. There is one specimen of aenea, with T believe 

 dark pubescence on the disk of the thorax, instead of yellow, 

 like the continental specimens. 



Microdon. Both species are here, about half-a-dozen of 

 each. 



Ceria. There is an imperfect specimen of conopsoides, 

 the head having been much injured, destroying the remark- 

 able antennae. 



If any gentleman will entrust their collections of Syrphidae 

 to me, I shall be most happy to arrange and name them. If 

 they will put all their specimens in a store-box and send by 

 rail, 1 think it would be best, as types picked out would very 

 probably miss allied species. It would be a benefit to both 

 of us, as it would improve the arrangement and nomenclature
