Yery like the preceding, but decidedly smaller and more elongate, it is one of 

 the smallest of the genus. The <J is entirely black, and can only be confounded with 

 the preceding and following species ; from puncticeps the form of the lacinia will 

 distinguish it, as also the pubescent bands of the antennae, which are produced to 

 neai'ly half the length of each joint ; from niger its armature will distinguish it at 

 a glance, and the wider 2nd sub-marginal cell of its wings with more contracted 

 apex. 



The ? may be known from puncticeps by its smaller size, paler legs, and paler 

 red colour of the abdomen, and in the form of the apical dorsal valve, as given 

 above. Length, 5 — 5^ mm.

7. niger, v. Hag., Deutsche Ent. Zeit., xxvi, 1882, p. 227, pi. vii, f. 26. 

 Another very small species, and very peculiar on account of the unusual form 

 of the armature in the ^ , which is strongly transverse ; the stipites scarcely strigose, 

 and very short and wide, and the lacinise very short, narrow, and concave, otherwise 

 in general appearance the <J resembles longulus, in colour the ^ is black or piceous- 

 black, and the genitalia dark brown ; the narrow 2nd sub-marginal cell is also a 

 character whereby this species may be known from longulus. 



? . 2nd sub-marginal cell scarcely contracted towards the apex ; face much 

 raised just below the insertion of the antennae; abdomen with the basal segment f 

 entirely red, all the rest more or less clouded with black. Length, 5 — 5| mm. 



I have only seen a single pair of this species, taken by Eev. E. H,, 

 N. Bloomfield at Gruestling, and which he has very kindly presented 

 to me.

 A large species about the size of gihhus. Alar hooks 5 — 6. 



S with the antennae short, reaching to about the scutellum ; the 3rd joint of 

 the flagellum about equal to the 1st and 2nd together ; the pubescent rings of thej \ 

 joints reaching to one-third of their length, or a little more ; thorax rather wide 

 closely punctured, and clothed like the head with grey hairs, face densely clothed 

 with white hairs ; wings hyaline, 2nd sub-marginal cell wide ; abdomen very shining ;|P ly

 black ; armature with the lacinia sub-quadrate and sub-membranous thickened in t 

 curved line across the centre, its apical margin fringed with long hairs. 



? very like gihhus, &c., in colour, but with the thorax closely punctured, anc 

 clothed with greyish hairs ; the apical dorsal valve wide and flat, punctured ; spine 

 of the tibiae pale. Length, 9—10 mm,
