Genus HOPLOCRYPTUS Thomson 



HOPLOCRYTUS BITUMINOSUS (Cushman), new combination 



C'ri/ptoidciis Mtuminmus Cushman, Proc. U. S. Nat. Mas., vol. 60, art. 4. p. 6, 

 1924. 



Since its publication this species has been received several times in 

 small numbers, reared from Pyrausta miUlalis (Hiibner) at Belmont, 

 Mass., and New Haven, Conn.; from P. penitalis (Grote) at Bono, 

 Ohio: from P. ainslieli Heinrich at York, Ind., and Bono, Ohio; and 

 ivom Diatraea at Grand Isle, La. Other localities, without rearing 

 data, are Nantucket, Mass., Englewood, N. J., and Baton Kouge, La. 



Among these specimens are several examples of the undescribed 

 male. This sex differs from the female in the usual secondary sexual 

 characters of smaller size, more slender form, especially of the abdo- 

 men, and more slender, longer, and apically tapering antennae. The 

 head is| a little broader behind the eyes and the wings a little less 

 deeply infumate. 



Genus CRYPTOHELCOSTiZUS Cushman 



The receipt of specimens of two undescribed species brings to four 

 the number of North American species referable to this genus. They 

 may be distinguished by the following key : 



1. Areolet large, first intercubitus more than half as long as second 



recurrent; wings deeply iufumate dichrous ViereeU 



Areolet small, first intercubitus not or barely half as long as 



recurrent; wings hyaline or diUitely infmnate 2 



2. Legs in female and hind tibia in male largely black ; postscutellum 



black ; wings in female dilutely infumate chrysobothridis, new species 



Legs in both sexes, except coxae and trochanters, red ; postscutel- 

 lum white ; wings hyaline ^ 



3. First abdominal segment entirely red ; posterior orbital mark very 



narrow and not contiguous with eye; scutellum and coxae 

 immaculate black and propodeum usually so ; tegula white only 



at base alamedensis (Ashmead) 



First abdominal segment black with apex red; posterior orbital 

 mark very broad and contiguous with eye; scutellum, propo- 

 deum, and coxae conspicuously white-marked; tegula entirely 

 ^jjj^g ornatus, new species
