cast doubt on the record of Ashmead "from an unknown lepidopterous 

 host." Also all specimens of the two new species described below were 

 reared from buprestids. 



The following specimens have been received since the publication of 

 rufigaster: 2 females and 2 males reared from Chrysohotkris inuU 

 Horn at Stanford University (May 15, 1922), Los Gatos (May 23, 

 1918), and Simla Station (June 28, 1922), Calif., under Hopkins U. S. 

 Nos. 16065 a 3, 15913 B 1, and 16634 a, respectively; one female "from 

 flathead borer on Mains sp.," Chico, Calif., February 15, 1912, J. K. 

 Horton; and one female, Corvallis, Oreg., April. 



CRYPTOHELCOSTIZUS DICHROUS Vieieck 



Cryptohelcostizus (liehroiis Vierkck, Psyche, vol. 28, p. 73, 1921. 



Distinct from all the other species in the deeply infumate wings and 

 large areolet. Viereck failed to note the red hind femora in the male. 



Before me are females from Manumuskin, N. J., April 29 and 

 October 21, 1901, and Virginia Beach, Va., October 18, 1922 (Jones- 

 Walker-Brannon) ; and males from Texas (Belfrage) and Conover, 

 N. C, October 8, 1919 (J. E. Eckert), the last compared by me with 

 the allotype. 



CRYPTOHELCOSTIZUS CHRYSOBOTHRIDIS. new species 



Structurally very like alameden^is Ashmead, but so distinct in 

 color, especially of the legs, as to appear specifically distinct. 



Female. — Length 12 mm., antenna 9 mm., ovipositor sheath 4 mm. 

 Black, with abdomen, except petiole, ferruginous, and with the 

 following whitish markings: Narrow lines in frontal and posterior 

 orbits (the latter not contiguous w^ith eye) and rarely a triangular 

 mark on cheek, narrow transverse streak on clypeus, incomplete an- 

 nulus on flagellar joints 8 and 9, and rarely the humeral margin of 

 pronotum and a small spot on base of tegula; flexor surface of front 

 tibia reddish; hind fenuir basally more or less pale or reddish above; 

 joints 3 and 4 of hind tarsus reddish; wings distinctly, though not 

 deeply, infumate. 



Male. — W\i\\ all white markings of female, except antennal an- 

 nulus, and also with facial orbits, spot on base of each mandible, and 

 joints 3 and 4 of hind and middle tarsi Avhite; front and middle 

 legs beyond trochanters and the hind femur largely or entirely 

 ferruginous.
