the mesonotum less densely sculptured and less dull than the 

 head, and with only very feeble sparse punctures ; scutellum pol- 

 ished; propodeum rugose before the truncation, posteriorly clull, 

 with very dense and fine close ru2:ulosity and generally some fine 

 transverse wrinkles, but without any defined area. Lamellate 

 denticles of chelae much as in the preceding. Stigma blackish 

 fuscous, otherwise the neuration pale, except the radius. Abdo- 

 men smooth and shining. Length 2-2.5 mm. 



HAB. Nogales, Arizona ; captured on weeds in September. 



3. Chclogynus liisus sp. nov. 



Black, the mandibles (except the teeth) wdiitish, the antennae 

 except the apical joint concolorous and lestaceous. legs concol- 

 orous with these, but the hind femora are to a large extent black 

 or blackish (the base being paler) and the apical part of the hind 

 tibiae is also dark. 



Head dull, densely minutely shagreened and with sparse traces 

 of obsolete punctures. Antennae formed much as in the preced- 

 ing, the apical joint alone dark. Pronotum very densely sculp- 

 tured like the head, and dull, and I cannot detect any trace of 

 the transverse rugulosity observable in the two preceding spe- 

 cies. ^Mesonotum dull with very fine surface sculpture, and a 

 few nearly effaced punctures ; scutellum polished ; propodeum as 

 in the preceding. Stigma blackish fuscous, radius also dark, 

 otherwise the nervures are pallid. Chelae much as in the preced- 

 ing. Abdomen smooth and shinnig. Length 2 mm. 



HAB. Tucson, Arizona ; bred from the same species of hop- 

 per and at the same time as C. funcstns, of which it might be a 

 sport, but the colour characters are very difl^erent and the sculp- 

 ture also dift"ers (no. 2420). 



Ant con Jur. 



The single species, which I refer to this genus, is congeneric 

 with examples I have examined from Germany, having a similar 

 structure of the chelae, and my Prosantcon from Australia is 

 synonymous with it. In the European, Australian and American 

 species the mouth-parts are as given by me in my characterization 

 of Prosantcon in Bulletin I of this Station, and not as given by 

 Ashmead in his Monograph of the Proctotrupidae and later writ- 

 ings. T consider the genus quite distinct from Chclogynus on 

 account of the non-extensile chelae, the fourth tarsal joint being
