24 CHALCID PAKA.SITES. 



There appear to be three specie.s of Spalangia described 

 as para&ites of fly pupae, viz., .S'. hirta Hal (Grahani-Smith, 

 1919, p. 37.3, fig. 18) and >S'. nigra Boule from Europe : and 

 S muscidarum Richardson from various localitie.- in the 

 United States. Sj^alangia sp. was figured by Hewict 

 (11114. p. 1(37). 



Howard (1911, p. 89) referred to finding one (,S'. nni.scce,. 

 MSS. name) parasitising house fly pupa? in Wai-hington^ 

 D.C. This was not described until 1913 when Eichardson 

 named it S. muscidarum , his material coming from Massa- 

 chusetts (Miisca domesHca) and Texas (Stotnoxys calcitrans)., 



Bishopp (1913, p. 124) reported that two species of 

 Pteromalida? parasitised the j^upsp of Siowoxys, one of them 

 being S. muscce {i.e., S. muscidar^im). Forty per cent, of 

 the pupae bred at Dallas, Texas, were found to have been 

 destroyed by these wasps which ^^ere capable of killing the 

 pupa? of the house fly and certain other muscids as well. 



Pinkus (1913) mentioned that A', mvscidarvm was the 

 commoue t parasite of the >table fly at Dallas, Texas, and 

 gave a desciiption of its habits and larval stages. It was 

 stated that the wasp did not discriminate, when given the 

 opportunity to OAaposit in the ])upa^ of various specified 

 muscids. 



Girault (1913, p. 332-3) described three species of 

 Spalinufia. S. grolin-ni, S. anstraUen.si-s, and *S'. rirginica 

 as ^^•ell as two of S palatigimorpha, Sp. fascialijiennis and 

 Sp. frater (p. 334) all from North Queensland. The three 

 species of Spalangia as well as another, S. parasitica (also 

 from North Queensland), and .S';;. fascia I ijjennis were 

 further described by him in 191.") (pp. 34o-fi). As far as 

 is known none of these attack flies. 



(2) Nasonia breviccn-nis Girault and Sanders.* 



This tiny ehalcid was described in 1909. the account 

 being supplemented in 1910. t The first record of its 

 occurrence in Australia seems to have been made by
