Ipocoelius Ruschka was placed in synonymy with Tomicobia Ashmead by Gahan 

 (1938 : 221), who compared two syntypes of Ipocoelius seitneri Ruschka (type- 

 species of Ipocoelius) with the type of Tomicobia tibialis Ashmead and found them 

 to be congeneric. 



The European species were revised by Hedqvist (1963). My views differ slightly 

 from those expressed in his paper, and his species ferrierei I have transferred to 

 Dir Menus. 



Key to European Species 



(Females) 



i Gaster subcircular, as broad as or broader than the thorax ; in dorsal view its 



apex does not appear conspicuously bristly. Head, mesoscutum, and scutel- 

 lum shiny, their sculpture for the most part engraved ; frons, vertex, and 

 mesoscutum with some small but distinct piliferous punctures. Pronotal 

 collar medially one twelfth to one eighth as long as the mesoscutum. 

 Antennal flagellum subclavate ; distal segments of funicle slightly trans- 

 verse ............ 2 



— Gaster oval, narrower than the thorax ; in dorsal view its apex appears very 



bristly. Head, mesoscutum, and scutellum less shiny, their sculpture at least 

 slightly raised above the general surface ; piliferous punctures of head and 

 mesoscutum not easily visible because of the relatively stronger reticulation. 

 Pronotal collar medially one sixth to one fifth as long as the mesoscutum. 

 Median area of propodeum nearly uniformly reticulate. Tarsi relatively short 

 and stout ; first segment of mid and hind tarsi only 2-5-3 times as long as 

 thick ; hind tarsi from hardly more than half, to about two thirds, as long as 

 their tibiae. Fore wing usually immaculate ...... 3 



2 (1) Antennal scape reaching almost or quite to the level of the vertex, its length 

 slightly greater than the transverse diameter of an eye. Tibiae and tarsi 

 relatively less stout ; the first segment of the mid and hind tarsi nearly 4 times 

 as long as thick ; hind tarsi slightly more than two thirds as long as their 

 tibiae. Median area of propodeum usually with some irregular wrinkles as 

 well as reticulation. Fore wing often with a distinct brownish cloud below 

 the marginal vein. Larger species, 2-2-8 mm. . . promulus (Walker) (p. 785) 



— Antennal scape not nearly reaching the median ocellus, its length hardly greater 



than the transverse diameter of an eye. Tibiae and tarsi stout ; the first 

 segment of the mid and hind tarsi only 2-2-2-7 times as long as thick ; hind 

 tarsi hardly two thirds as long as their tibiae. Median area of propodeum 

 uniformly or nearly uniformly reticulate. Fore wing with a hardly visible in- 

 fumation below the marginal vein ; stigmal vein forming a rather more acute 

 angle with the postmarginal than in promulus. Smaller species, less than 

 2 mm. in length ..... subincrassata (Thomson) (p. 786)
