516 BOMBYLID^ 



The Anthracince are the most sharply defined subfamily in the 

 Boinbylidce, owmg to the long prsefurca and the pecuhar divergence of 

 the radial vein at its fork from the cubital, the oblong flattish figure, 

 the well separated antennae, and (usually) well separated eyes in both 

 sexes; Henica Macq. { = Lagochilus Lw.) is peculiar in having the discal 

 cross-vein placed much further on towards the end of the discal cell, and 

 in Mnlio and Callistoma the divergence of the radial and cubital veins 

 is not very abrupt and takes place before the middle of the discal cell, but 

 the long prffifurca readily distinguishes them from the other subfamilies. 

 The upper knee-like angle at the divergence of the radial vein frequently 

 throws back an incomplete recurrent veinlet towards the base of the wing, 

 but such veinlet is seldom of even specific value, and even the adventitious 

 cross-veinlets from the upper branch of the cubital fork are in some cases 

 not of specific value, though they have been used in some cases for 

 generic distinctions ; the first posterior cell may be open or closed in 

 closely allied species, but is wide open in all the British species. 



Syiionymy. — The distinct appearance of the Anthracince as contrasted with the 

 common species of Bovihylms early gave rise to a suggested family Anthracidce, but 

 a wider knowledge has relegated them to their proper position as a subfamily of 

 the BcymhyliclcB.
