long as postocellar line and nearly four times as long as ocell-ocular 

 line. Face entirely and all thoracic markings yellow, the latter 

 including the lateral aspect of the pronotum, the notauli and a 

 median spot on mesoscutiim; petiole laterally and lower edge of

 is black only on apex of tibia and tarsi.

Two females and five males reared by F. P. Breakey during May 

 and June, 1928. 



Genus CREMASTUS Gravenhorst ( = CREMASTIDEA Viereck) (new 



synonymy) 



Cremastidea is said to differ from Cremastus Gravenhorst by the 

 very short malar space and by the fact that the propodeum overlies 

 the hind coxae to their middle. 



The first character is subject to great variation in Cremastus and 

 is sometimes a sexual difference; while the second is characteristic of 

 typical Greinastus. 



The genotype, Cremastidea chinensis Viereck, is a typical Cre- 

 mastus. 



(CREMASTIDEA CREMASTUS CHINENSIS (Viereck) (new combination) 



In addition to the types the National Museum Collection contains 

 six specimens reared by D. T. Fullaway at Kobe, Japan, as parasites 

 of the rice borer, Chilo simplex Butler. 



THERSILOCHUS PROVANCHERI Ashmead ( = THERSILOCHUS PROVANCHERI Cusliman) 



In renaming Provancher's preoccupied pallipes I overlooked the 

 fact that Ashmead had already done so.^ Dalla Torre catalogued 

 the Ashmead reference under Porlzon angularis (Provancher). 



ALLOPHRYS OCULATUS (Ashmead) (new combination) 



Thersilochus oculaUis Ashmead, Proc. Zool. Soc. London, 1895, p. 779, male. 

 Insurgus nigriceps Ashmead, Trans. Eut. Soc. London, 1900. p. 273, female. 

 (New synonymy.) 



The large, dorsally convergent eyes of Allophrys Foerster consti- 

 tute a male secondary sexual character, the eyes of the female being 

 of normal size and parallel within. 



The association of the sexes is based on a series of specimens col- 

 lected on the windward side of Grenada, West Indies, by H. H. 

 Smith.
