Qen. ch. — Species small, black, and glabrous, with oblong conical 

 bodies ; eyes bare ; frontalia wide in both sexes ; cheeks narrow, and 

 armed with a long row of strong bristles, continuous above with 

 the inner fronto-orbital setae, which are in a double row in both 

 sexes ; facialia bare ; chin large and setose ; antennse long, the third 

 joint being from three to five times as long as the second ; arista bare ; 

 abdomen mostly with both discal and marginal seta? ; wings with the 

 third longitudinal vein ciliated from the root to the little cross vein, 

 or to a little beyond it ; first posterior cell closed, and with a longer 

 or shorter stalk, outer cross vein situated nearly midway between the 

 inner cx-oss vein and the beud of the fourth.

Frontal stripe subrufous ; sides of frontalia and face grey, with dark reflections ; 

 antennae black or grey, with third joint thick, and only about three times the length 

 of the second ; arista thickened nearly to the middle ; palpi black ; thorax black, 

 rather aeneous, marked in front with three short, wide, black stripes, and having 

 some white pubescence on the shoulders and sides ; post-sutural outer dorso-central 

 bristles three in number ; abdomen shining black, with a narrow white band on the 

 front margins of the second, third and fourth segments, which are armed with both 

 discal and marginal setae ; wings slightly tinged with brown, having the apical cross 

 vein deeply incurved and joining the third near the costa, leaving a short stalk not 

 more than a fourtli or fifth of the length of the outer cross vein, which is slightly 

 curved and placed a little nearer to the bend of the fourth than to the little cross 

 vein ; a short cubital appendix is sometimes present ; third longitudinal vein ciliated 

 as far as little cross vein j veins not nebulous. 



This well marked species is not common. I captured it near Bradford in 1876, 

 and again at Silverdale in Lancashire in 1881. 



S CARBONARIA, Pz. 

 Characters of head and face as in the former species, with the exception of 

 having the palpi yellow, and the antennae rather longer, much narrower, with their 

 bases testaceous ; the thorax is also similar ; the abdomen is entirely black and less 

 setose ; the wings are fuliginous, with the fore borders very dark, and the veins 

 nebulous ; the apical cross vein is much less curved than in H. trU-iticta, and the
