Collin — Notes on Specimens of Borboridce and some Ephydridce. 255 



The " division C. b." referred to is that of Meigen Syst. Beschr., vi, 117, 

 and the "last" species /oss«r««w* Hal. 



In 1839 Haliday re-deseribed it as follows : — 



" Sp. 16. hecate, E. N. fusco-senea tarsis basi ferrugineis, alis 

 fuscanis, nervis trausversis obseuris utrinque hyalino-guttatis. 

 " Ent. Mag. i, 175.— Uph. fuscipennis, Maoq. S. k B. ii, 540. 

 " Hollywood : very rare." 



Loew (1860) appears to have been responsible for placing this species as a 

 synonym of coarctata, from which, however, it is abundantly distinct, being 

 smaller, darker, with more clouded wings, shorter radial vein, the costal 

 segment between subcostal and radial veins being somewhat shorter than 

 between radial and discal veins; the radial vein is curved upwards, ends 

 almost at right angles to costa, and has a distinct cloud about tip. The 

 pre-scutellar dorso-central bristle is strong, the two others in front of it 

 weaker, but not weaker than the post-humeral. It is identical with the species 

 added by me to the "List" (Ent. M. Mag., 1911, p. 185) as obliqua Becker. 

 The synonymy ol fuscipennis Macq. is very doubtful. 



One specimen labelled " hecate " and two others in Haliday's collection.
