282 FAUNA HAWAIIENSIS 



Of the above species, Evania appendigaster Linne, parasitic on the oothecae of 

 cockroaches, its hyperparasite, TetrasticJms hagenowi Ratz., Metacoelus femora/is, 

 parasitic on Lepidopterous larvae, and Bassus lactatoiniis, parasitic on Dipterous larvae, 

 are now cosmopolitan species. 



Bibliographic. 



The literature relating to the parasitic Hymenoptera of the Hawaiian Islands is 

 not extensive, the following being all that I have been able to find : — 



1. Cameron, P. Notes on Hymenoptera, with Descriptions of New Species. (Trans. Ent. Soc. 



London, 1881, pp. 555—562.) 



Describes: Sierola (n. g.) tesiaceipes, Chelotius carinaius, Monolexisl palliatus, Chalcis 

 polynesialis. 



2. . Descriptions of New Genera and Species of Hymenoptera. (Trans. Ent. Soc. London, 1883, 



pp. 187—193.) 



Describes : Epitramis ladeipennis, Moranila testaceiceps, SoUndenia (n. g.) pictuoniis, 

 Eiipelmus flavipes, Evania sericea, Limneria polynesialis, L. Blackburui, Ophion lineatics 

 and O. tii^ricans.

§ 2. Systematic account of the Hymenoptera Parasitica. 



Superfamily III. VESPOIDEA. 



Family XXXII. BETHYLIDAE. 



This family, which is composed of purely parasitic species, is quite extensive 

 and has representatives in all parts of the world. It was first correctly placed by 

 A. H. Haliday, as early as 1839, among the so-called fossorial wasps, but was sub- 

 sequently removed and treated by Prof. John O. Westwood as a subfamily in the family 

 Proctotrypidae. 



Following the views of Prof. Westwood, it was so treated by Forster, Thomson 

 and most of the subsequent writers on these insects and by the author in his Mono- 

 graph of the North American Proctotrypidae, published in 1893. Since that time.
