REVISION OF LEUCOSPIDAE 229 



horse-shoe macula on truncation, in one specimen narrowed in middle (above) ; narrowest part 

 of gaster red. Infumation of wings faint, sometimes absent. Flagellum slightly clavate' 

 combined with pedicellus 1-17-1 -20 times as long as breadth of head. For shape of gaster see 

 Text-fig. 271 ; very similar to M. steffani, but in general more slender anteriorly and puncturation 

 denser. 



Biology. Unknown. 



Distribution. South West Africa, South Africa. 



Material examined. 



South West Africa: Aus. i. 1930, 1 $, 3 J (R. E. Turner) (BMNH). South 

 Africa: Aliwal North, xii. 1922, 1 $ (larger one) {R. E. Turner) (BMNH). 



I considered the probability of identity with Micrapion steffani. The size and 

 the stouter antenna of the dwarf specimen cannot be taken as reliable characters; 

 usually, however, the smaller specimens of the same species have relatively much 

 coarser and sparser sculpture, which is quite to the contrary in this case. 



The species is not being named through lack of a suitable holotype; in the larger 

 female the head is missing, the other female is a dwarf and the males often do not 

 show specifically reliable characters. 



MISPLACED TAXA 



MARRES Walker, 1841 : 217. Type-species: Marres dicomas Walker, by monotypy. 

 Schletterer (1890 : 298-299) treated this genus and its only species described from 

 West Africa as close to Leucospis Fabricius. Menon (1949), after having studied 

 the type of M. dicomas, concluded however that the species and genus belong to 

 Chalcididae. I can confirm this as correct. 



Coelogaster conicus Schrank, 1802 : 222-223. Type(s), Austria (?lost). 



As a consequence of Coelogaster Schrank having been put in synonymy with 

 Leucospis Fabricius, C. conicus was also synonymized, with a query, with Leucospis 

 dorsigera Fabricius by Dalla Torre (1898 : 408). The type-material of conicus is 

 probably lost but from reading the description I do not think that the species was a 

 Leucospid. The thorax is described as 'golden green', which would suggest rather 

 a Pteromalid. 



Leucospis integra Haldeman, 1844 : 53, $. Type(s), U.S.A.: PPennsylvania (lost). 

 Already Cresson (1872 : 35) suggested that this species was probably the same as 

 Chalcis ovata Say, called nowadays Brachymeria ovata (Say). This synonymy 

 was accepted by Ashmead (1904 : 408), who called the species Chalcis annulata 

 Fabricius, but not by the more recent American authors; Peck (1963 : 899-900), 

 for example, has L. integra among the Unplaced Species. I think, judging from 

 the description only, that Cresson was most probably right. The original material 

 is believed to be lost ; it was not among the remnants of the Haldeman types given 

 to Saussure and brought by him to Geneva (see Schulz, 1911 : 75, 149).
