THE ENTOMOLOGIST. Q3 



captured in the New Forest, but they have now been removed 

 from the British collection, as more must be known of their 

 history before so striking a species can be acknowledged. 



Sericomyia. Plenty of both species, and also of Arctophila 

 mussitans. 



Erislalis. In this genus Mr. Newman has lately much im- 

 proved the collection, there being now fine series of most of 

 the species, showing strong varieties under pertinax ; a num- 

 ber of Pratorum ? ; one Cryptarum ; four seneus, but none 

 called stygius ; and two male Rupium. 



Helophilus. There is the finest collection of this genus 

 that 1 have seen, there being the two allied species floreus 

 and nigrotarsatus, looking remarkably distinct; a row of 

 pendulus; three hybridus ; eight trivittatus ; four versicolor ; 

 nine lineatus ; seven lunulatus ; three transfugus and several 

 vittatus, all of which, except the first three, are rare species. 



Merodon. There is one fine male specimen belonging to 

 this genus which I cannot identify. 



Tropidia. Nearly a row of milesiformis. 



Spilomyia. Six specimens of the handsome exotic-looking 

 speciosa. 



Xylota. All the species are here, including nearly a dozen 

 lenta, two specimens called bifasciata, which certainly seem 

 to differ from my Nemorum, and one specimen, perhaps a 

 variety of Nemorum. 



Syritta. Of course abundantly. 



Brachypalpus. Five specimens of bimaculatus. 



Criorhina. There are all the species, including three 

 specimens each of the handsome and rare Ranunculi and 

 berberina ; and a dozen each of the others. 



Myolepta. There is one specimen of the rare luteola. 



Eumerus. This genus is very poorly represented, there 

 being altogether only four lunulatus. 



Chrysogaster. Most of the species are here, though the 

 collection is not good in this genus : there are a pair of unset 

 specimens called splendida ; ten metallina, the males of which 

 are separated as discicornis; more than a dozen specimens 

 labelled viduata, which probably include Macquarti; half-a- 

 dozen splendens ; four or five chalybeata ; about half-a-dozen 

 Coemeteriorum, and another half-a-dozen called fumipennis, 

 which may be a distinct species, but the specimens look to
