Some Hyperparasites of White Grubs. 



BY OTTO II. SWEZKY. 



Tn ]\ray, lOl-i, 56 cocoons of Elis sexrincta were received 

 from ]\Ir. George I^. Wolcott. He had collected these at Vv- 

 l)ana, Illinois, while collecting cocoons of Tipliia to send to Por- 

 to Rico. Xot desiring to make nse of the Elis cocoons, he for- 

 warded them t<^ the Ex])eriment Station, where we expected to 

 experiment witli this species as a parasite on the grnl)s of A)io- 

 innln and Adovcius. There were not many emergences from the 

 lot and they were mostly males; only one female emreged. She 

 lived for several weeks bnt failed to ]iarasitize any of the grnbs 

 that were snp]died her in the cage. 



From this lot of cocoons one male and one female ^Mntilid 

 emerged, and one Bombyliid. Carefnl examiiuition showed 

 that with each of them they had been ]^arasitic on the Eli>i. and 

 tlins were hyperparasites of some white grn!) — ])resnmably some 

 species of Laclinosterna. 



The Bombyliid was A)if]ir(i.r fiilmliirfa Wied. 1 have nor 

 seen any reference in literature to its host rc4ationshi])s. In Dr. 

 Forbes'' 24th Illinois Report, 1008, on i^age 160, a Pxnnbyliid 

 (Exoprosopa fascipeimis Say) is mentioned as a ])arasite on 

 Tij)]iin. and is thns also a liyjierparasite on white grubs. On 

 ])age 161 of the same Re])ort, another Rondndiid ( SpaniopoJiiis 

 fiilrus "Wied.) is mentioned as a direct ])arasite on white grnbs.
