50 INSECT ENEMIES OF THE BOLL WEEVIL. 



sive with that of its host, the boll weevil. In previous pubH- 

 cations it has been recorded as a parasite of Lixus musculus Say, L. 

 scrohicollis Boheman, Apion segnipes Say, Anthonomus Jieterothecse 

 Pierce, Anthonomus squamosus LeConte, Tyloderma foveolatum Say, 

 and Orthoris crotcTiii LeConte. To this list may be added (BrucJius) 

 Laria exigua Horn in Amorpha pods at Dallas, Tex.; {Bruchus) 

 Laria sallsei Sharp in pods of huisache ( VacJiellia farnesiana) col- 

 lected at Victoria, Tex.; SpermopJiagus rohinise Schonherr in pods of 

 the honey and water locusts ( Gleditsia triacanthos and G. aguatica) 

 in Louisiana; Macrorhoptus spliseralcise Pierce in pods of SpJiseralcia 

 at Del Rio, Tex.; Smicraulax tuherculatus Pierce in mistletoe stems 

 at Dallas, Tex.; Trichoharis texana LeConte in stems of Solanum 

 rostratum at Cisco and Victoria, Tex.; and also Trichoharis trinotata 

 Say; and finally it was reared in September, 1908, from Baris spTin 

 roots of ambrosia at Camden, Ark., by C. E. Hood. 



Eurytoma sp. A female primary parasite and a male accidentally 

 secondary on Microhracon mellitor Say were reared from hanging 

 squares collected August 10, 1907, at Victoria, Tex. 



PERIL AMPID^, 



Perilampus sp. A single individual was reared from the boll weevil 

 in an isolated weevil cell by C. E. Hood from squares collected Sep- 

 tember 7, 1907, at Shreveport, La. Another specimen of Perilampus 

 was reared from squares collected at Granbury, Tex., August 8, 1907, 

 but its source could not be proved. If it were not for the definite 

 record made by Mr. Hood these species could hardly be placed in 

 this Hst. This record may possibly be based upon the parasite of an 

 intruder in the weevil ceU instead of upon the weevil itself. It is 

 not impossible that after several years this parasite may be found 

 normally as a boU- weevil parasite, as was the case with Sigalphus 

 curculionis. 



ENCYRTID^. ETJPELMIN^. 



Ceramhycohius cyaniceps Ashmead. The list of hosts of this spe- 

 cies as previously recorded included Anthonomus alhopilosus Dietz, 

 {Bruchus) Laria ohtecta Say, L. exigua Horn, Lixus musculus Say, 

 TricJioharis texana LeConte, and Tyloderma foveolatum Say. To this 

 hst may be added Laria hisignata Horn in pods of Acuan illinoensis; 

 L. ochracea Schaeffer in pods of Vicia sp.; L. sallsei Sharp in pods of 

 huisache ( Vachellia farnesiana) ; Spermophagus rohinise Schonherr in 

 pods of Gleditsia triacanthos at Alexandria, La.; Lixus scrohicollis 

 Boheman in stems of Ambrosia trifida and A. psilostachya; Apion 

 rostrum Say in pods of Baptisia tinctoria at Washington, D. C; 

 Tachypterellus quadrigihhus Say in fruit of Cratsegus mollis at Vic- 

 toria, Tex.; Smicraulax tuherculatus Pierce in stems of mistletoe
