Anthomyid genera Hammomyia and HylepJiila. 315 



and, by kind permission of Prof. Sjostedt, figures of the 

 genitalia were made from the male so labelled. Zetter- 

 stedt's original description of unilineaia applies best to the 

 species described above, and his name must be so used in 

 spite of the fact that such a Hmitation of the name is not in 

 agreement with the views of recent writers. Stein's uni- 

 lineata (Arch. f. Nat. Ixxxi, 1916, p. 162) appears to be 

 ohtusa Zett., while according to the figures of the male 

 genitalia of Schnabl and Dziedzicki's unilineaia in " Die 

 Anthomyiden " (1911) their specimen must have been 

 unistriata Zett. 



H. unilineata is at present known from Sweden only. 

 Meade certainly added the name to the British List in 1882 

 (Ent. M. Mag. xix, 146), but his specimens were more prob- 

 ably H. sjjonsa. The name unilineata has also been used 

 for personafa by Verrall.

(J. Darker and more hairy than the male of any other British 

 species. Compared with personata all the hairs and bristles are 

 much longer, and there are longer and more numerous upcurved 

 bristles along the oral margin on the jowls, and conspicuously longer 

 and more numerous fine hairs (as distinct from the bristles) on the 

 thorax. Disc of thorax distinctly darker, and, when viewed from 

 the side or behind, with indications of five darker stripes, of which 

 the three inner ones follow the lines of the acrostichal and dorso- 

 central bristles, the broader side stripes being most distinct above 

 the root of wing; viewed right from in front the whole thorax 

 appears distinctly greyer. Abdomen less distinctly tessellated, 

 though all markings vary according to the point of view; on the 

 whole, however, there is a stronger tendency to darker hind-margins 

 to segments than in ji^fsonala. Legs much more hairy and with 

 less distinction on the femora between the hairs and bristles. Hind 

 coxae densely clothed in front with curved fine hairs. Front femora 

 densely long-haired on the whole of the posterior surface, the postero- 

 dorsal and posteroventral rows of bristles very little differentiated ; 

 middle femora with no long anteroventral ciliation but with a
