December, '11] CUSHMAN: HOSTS AND PARASITES OF BRUCHID^ 499 



pods collected November 20, 1907, at Brownsville, Texas, by Mr. 

 J. D. Mitchell, in company with many specimens of B. quadridentatus 

 Schaef. 



Several specimens were recently received at the Department of 

 Agriculture from Mr. M. M. High. These were reared by Mr. High 

 from "Ebony" at Brownsville, Texas, March 6, 1911. The "Ebony" 

 is undoubtedly Siderocarpus flexicaule. 



Bruchus obtectus Say, Cure. N. A., p. 1; Leconte Ed., I, p. 261. 



Very little attention was given to this species, only one lot of infested 

 material having been collected. This was part of a sack of badly 

 riddled red kidney beans found by the author in a wholesale grocery 

 house at Shreveport, La. No parasites were secured from this lot. 



Chittenden (Yearbook U. S. Dept. Agr., 1898, p. 242) recorded 

 Ceramhycohius cyaniceps Ashm. and Bruchohius laticollis^ Ashm. as 

 valuable parasites of this species. 



Bruchus schrankiae Horn, Trans. Am. Ent. Soc, 1873, p. 339. 



This species, originally described by Horn from Schrankia uncinata, 

 was reared from one lot of the pods of a species of "cat-claw" {Mimosa 

 horealis) collected May 4, 1907, at Devil's River, Texas, by Mr. F. C. 

 Bishopp. It was associated on this plant with Apion pyriforme Sm. 

 On May 4, 1907, a single specimen was bred by the author from a 

 pod of "black chapparal, " Acacia amentacea, in company with B. 

 salloei and Apion suhornatum. From the Mimosa the first adults 

 emerged May 17, and the last June 8, giving a maximum of thirty- 

 five days and a minimum of thirteen days from the date of collection. 

 No parasites of this species w^ere reared. 



Bruchus distinguendus Horn, Trans. Am. Ent. Soc, 1873, p. 336. 



This species was mentioned by Blatchley in his "Coleoptera of 

 Indiana" as being reared from Bracca virginiana. Our only breeding 

 record was secured by the author on January 10, 1907, at Nacogdoches, 

 Texas, where a few pods of Rhynchosia latifolia were found containing 

 the immature stages. A weevil, the adult of which was never secured, 

 also breeds in these pods. Eight adult B. distinguendus were reared 

 from the small amount of material obtained, the first two on July 29 

 and the last three on August 2. This gives minimum and maximum 

 periods from the date of collection of nineteen and twenty-three days 

 respectively. This is probably considerably short of the develop- 

 mental period, as all the larvae observed were well grown at the time 

 of collection. 



A chalcid of the genus Chalds or a closely allied genus was bred 

 from the material, but its source could not be determined. It was,
