(fig. 12). It bred from pupa^ taken at Chino and Oxnard. Cal. This 



parasite was also reared from the pupae of an unidentified tortrieid 



found feeding on the leaves of sugar beet at the same places. Three 



species of Hymenop- 



terous parasites were 



reared, but with the 



exception of the one 



noted below it was im- 



IDOSsible to tell whether 



they were bred from 



larvae or pupa?. They 



were identified by Dr. 



W. H. Ashmead, of 



the United States Xa- 



tional Museum, as 



Chelonus iridescens 



Cr., Spiloehcdeis tor- 



vina Cr., and Habro- 



hracon hebetor Say. 



Specimens of Che- 

 lonus iridescens (fig. 



13), issued from pupae 



of the crown borer in early October. This parasite is represented in 



the National Museum collections by specimens from Agricultural Col- 

 lege, Mich. ; Washington, D. C. : South Dakota ; Colorado ; Wyoming; 



Corvallis, Oreg. ; (xar- 

 lancl, Utah ; Kukak 

 Bay, Alaska; East on. 

 Wash., and San Diego, 

 Cal. The last of these 

 specimens (bearing 

 the U. S. Dept. Agr. 

 No. T97P°) was bred 

 from a phyticid larva 

 (or from the pupa) 

 found feeding in the 

 seed pods of Aphyllon 

 tuberosum. This spe- 

 cies is entirely black 

 except the legs, which 

 are marked with pale 

 yellow ; about 4 mm. 



in length ; verj^ rugosely punctured on thorax with longitudinal striae 



on abdomen. 



But one specimen of Habrobracon hebetor Say was reared from the
