PTEROMALIDAE OF N.W. EUROPE 559 



nearly smooth ; spiracles short-oval, separated by about half their length from hind margin of 

 metanotum ; callus sparsely haired. Postspiracular sclerite for the most part irregularly 

 reticulate, with a curved oblique impression. Lower part of mesepisternum, and mesepimeron, 

 rather coarsely reticulate, the metapleuron rather more finely. Legs rather slender. Fore 

 wing slightly more than twice as long as broad ; upper surface of costal cell bare except for a 

 few hairs near its apex, lower surface with a complete row of hairs plus some scattered hairs in 

 the distal third ; basal vein pilose throughout, also a few hairs in the distal third of the basal 

 cell, the latter open below ; speculum partly open below, on upper surface of wing extending 

 a little beyond the beginning of the marginal vein ; marginal vein 1 -5 to 1 -6 times as long as the 

 stigmal vein, the latter only very slightly curved and with a moderate-sized subrectangular 

 stigma ; postmarginal vein slightly longer than the marginal ; apical margin of wing ciliate 

 throughout, the fringe fairly long. 



Gaster long-ovate, about as long as head plus thorax, 2 to 2-3 times as long as broad ; basal 

 tergite occupying about a quarter of the total length ; last tergite about as long as its basal 

 breadth ; ovipositor sheaths slightly projecting ; hypopygium extending about half way along 

 the gaster. 



cJ. Unknown. 



Holotype $. Sweden : Narke, Orebro, 18.vii.1947 (A.Jansson), in Naturhistoriska 

 Riksmuseum, Stockholm. 



Paratype. Scotland : Mid Perth, Kenmore, 1 $, 19.vii.1954 (Graham), in 

 Graham collection. 



In the collection of the late Dr. A. Jansson there is another, slightly deformed, 

 specimen, captured at Orebro on 26.vii.1952. It is mainly female, but has peculiar 

 antennae with the scapes broader than in the normal female, and the left scape 

 very broadly expanded above the middle ; it may be an imperfect gynandromorph, 

 and is not included in the above description. 



Biology. Unknown. 



This species is rather isolated in Habrocytus, as may be seen from the characters 

 used in the key to species, and is almost intermediate between that genus and 

 Cecidostiba.

 Habrocytus conopidarum (Boucek) comb. n. 



Dirhicnus subcoeruleus Postner, 1951 : 79 [nee Thomson, 1878]. 

 Dirhicnus conopidarum Boucek, 1961a : 445-449, 6* $. 



Type material. Holotype $, Czechoslovakia, Bohemia, Filipov, 6.viii.i959, 

 ex Physocephala vittata (F.) in adult Bombus lapidarius, in Narodni Museum, Prague 

 (Cat. no. 2975) ; paratypes in the same museum and in Deutsches Entomologisches 

 Institut, Berlin. 



This interesting species is rather difficult to place generically. Boucek referred 

 it to Dirhicnus but admitted that the characters by which it differed from the 

 type-species of that genus might be great enough for it to be considered generically 

 distinct. I do not think it is satisfactorily placed in Dirhicnus ; in particular the 

 form of the gaster in the female differs considerably from that of Dirhicnus pirus. 

 On the other hand it is not easy to separate from Habrocytus, although it has a
