Ocelli in a moderately high triangle, the posterior, transverse tangent to the 

 anterior ocellus hardly touching the hind pair ....... 7 



Mesoscutum and upper part of side of pronotum bright reddish-yellow ; rest of thorax 

 black ; disc of scutellum polished, impunctate, bare, slightly projecting behind 

 over the basal part of the postscutellum ; posterior extremities of the lateral, rugose 

 tongues of the scutellum widely separated behind (Text-fig. 257). Tasmania 



resplendens- group (p. 216) 



Thorax entirely black ; disc of scutellum with at least an indication of punctures, hairy 

 all over, not projecting over the basal part of the postscutellum ; distance between 

 the posterior extremities of the lateral, rugose tongues of the scutellum much 

 shorter. Australia ....... tnorata-group (p. 217) 



The WESMAELI-Grovv 

 Monobasic. 



Hypomicrogaster wesmaeli (Ruthe) comb. n. 



Microgaster wesmaeli Ruthe, i860 : 148. 



This is a remarkable little species, without close allies so far as I know and perhaps 

 not very naturally placed in Hypomicrogaster. 



$. Ocelli in a high triangle, with the posterior, transverse tangent to the anterior ocellus 

 passing far in front of the posterior pair ; further, the ocelli are small, the posterior ocellus being 

 separated from the eye-margin by about three and a half times its own diameter. Top of head, 

 mesoscutum and disc of scutellum highly polished. Propodeum vaguely rugose and with a more 

 or less clearly defined, short, basal keel. Stigma short, rather broad. Inner spur of the hind 

 tibia slightly more than half as long as the hind basitarsus. Median field of tergite (2 + 3) sub- 

 rectangular. 



Europe. 



Location of type unknown. 



Monobasic. 



The VIRBIUS-Grovp 



Hypomicrogaster virbius sp. n. 



°2. Black ; tergite (2 + 3) except for the median field, yellow. Scape yellow. Clypeus 

 somewhat yellow medially. Front and middle legs yellow ; hind coxa and hind femur, except 

 at tip of femur, yellow ; hind tibia on apical third and hind tarsus throughout, infuscate. 

 Wings faintly tinted with brown ; venation brown throughout ; setae brown. 



Face smooth, impunctate but with a pronounced satin-like sheen. Vertex between the ocelli 

 and the eye-margin with only the merest trace of punctation and the satin-like sheen. Antenna 

 about as long as the body with segment 17 one and one third times as long as wide ; fiagellum 

 with somewhat upstanding, bristly pubescence. 



Mesoscutum dull, with satin-like sheen ; with heavy but very superficial punctation ; the 

 course of the notaulices is very slightly impressed and the punctures here are larger and virtually 

 contiguous. Disc of scutellum smooth with satin-like sheen and with the merest trace of 

 punctation towards sides ; lateral, polished zone of scutellum pushed far forwards and cutting 

 off between itself and the disc a long narrow furrow. Areola of the propodeum large (Text-fig. 

 259). Areolet minute (Text-fig. 261) ; vannal lobe of the hind wing very slightly concave 

 beyond its widest part and here without trace of a hair-fringe. Inner spur of the hind tibia
