stalk is much longer, being about two-thirds of the length of the outer cross vein ; 

 there is also sometimes a short cubital appendix. 



Not common. In Mr. Dale's and Miss Prescott-Decies' collections. 



S. LUGENS, Mgn. 

 Rather larger than the last species, with a long subcylindrical abdomen in the 

 male ; frontalia with central stripe piceous and rather narrower than the sides, which 

 are shining black, somewhat raised and tuberculated, having snowy-white reflections 

 in certain lights ; face silvery-white and glittering, with dark reflections, and armed 

 along its whole length with a row of strong setse, continuous with the inner row of 

 frouto-orbital bristles ; antennae black and thick, with the third joint scarcely three 

 times the length of the second ; arista thickened to about the middle, where it 

 suddenly becomes thin ; palpi yellow ; thorax shining black and immaculate, with 

 shoulders slightly grey ; abdomen black, very setose, and without discal setse on the 

 second segment ; alulee large and white ; halteres with red stalks and white heads ; 

 wings slightly nigrescent, especially along the front border, third longitudinal vein 

 ciliated up to the little cross vein ; fourth vein bent at an obtuse angle, apical cross 

 vein a little incurved, and meeting the third vein at some distance from the costa, so 

 as to leave a stalk about three-fourths of the length of the outer cross vein, which is 

 quite straight and centrally placed. 



Rare. I have only seen a single male, which is in the Rev. E. N. Bloomfield's 

 collection.

ScopoLiA, Schnr., -p. 



Tachina, Zett., J). 



Gen. cJi. — Species small and black, with short ovoid bodies ; eyes 

 bare ; frontalia wide in both sexes ; fronto-orbital bristles in a double 

 row in both male and female, and extending as low as the apex of the 

 second joint of the antennse ; cheeks narrow and bare ; chin small ; 

 facialia ciliated half or two-thirds of the way up ; antennae long, with 

 the third joint four or five times as long as the second ; arista bare ; 

 thorax short and wide ; abdomen short, thick and oval, with both discal 

 and marginal setae ; wings with the third vein unarmed, with the ex- 

 ception of the ordinary two or three setae at the root ; first posterior 

 cell closed, and having a stalk of moderate length ; legs short. 



I have separated this genus from ScopoUa, from which it differs 

 by the species being shorter and rounder in shape ; by having the 

 facialia ciliated, and not the cheeks ; by the third longitudinal vein of 

 the wings being without setae ; and by the legs being shorter. 



B. OCTPTEKINA, Zett. 



Frontal stripe dull and piceous, rather wider than the sides of the frontalia, 



which, with the face, are cinereous with dark reflections ; antennae grey, with the 



second joint lighter in colour than the third ; arista thickened to about the middle ; 



palpi piceous; thorax shining black, with slight grey pubescence, and having four
