Nev) Gemra of British Mymaridae. 459 



by 0"275 broad, the cilia long. The tarsi of the front, middle and 

 hind legs longer than tibiae, those of the hind pair are the longest, 

 viz. tibiae 0"35 mm., tarsi 0*5 mm. The ovipositor projecting beyond 

 the tip of the abdomen, which is pointed at the base and tip. 



Doriclytus vitrijoennis, Forster. 



General colour black. The antennae of the male 13-jointed, of the 

 female 9-jointed. The joints of the male are long and narrow. From 

 the 3rd to the 12th of about the same length, the 13th a little shorter, 

 the scape long and slender, the pedicel about half the length of the 

 scape, and of a slightly lighter colour. The antennae of the female 

 varying in colour from the pedicel which is light testaceous to the 

 club, of intense black ; the 3rd joint is the shortest and narrowest, 

 the club as long as the 3rd and 4th combined. The head is wider 

 than the thorax . The wings long and curved on the costa and inner 

 margin, the curve of the outer margin forming an obtuse finish. The 

 anterior wing is 1"13 mm. long x 0"275 broad. The longest cilia 

 0'23 mm., the surface covered with short hairs. The legs form good 

 characteristics of this genus, all the tarsi being much longer than the 

 tibiae — those of the hind legs are 0"5 mm. long, against 0'35 mm. of 

 the tibiae. The front edge of the tibiae of the front legs is armed 

 with sharp projections, surmounted by a fine hair ; the femora and 

 tibiae are black, with testaceous tips and bases ; the tarsi light 

 testaceous, the 4th joint brown and the 1st much the longest. The 

 trochanters black, the coxae yellowish. The petiole is testaceous. 

 The ovipositor projecting slightly beyond the tip of the abdomen, 

 which is pointed both at the base and tip. 



Length 1 mm. 



Rab. Hollow AY, London, N. : $ July 1897 ; ? July 

 1908 (Fred. Enock). 



Both species caught on the same pane of glass, with an 

 interim of eleven years. 



This genus, new to Great Britain, was first established 

 by Forster in 1847. 



It is near to Cosmocoma, but the very long tarsi separate 

 it from that genus.
