Bruchus amicus Horn, Trans. Am. Ent. Soc, 1873, p. 337. 



This species is recorded by Riley and Howard (Ins. Life, V, 165) 

 as breeding in the pods of Parkinsonia torreyana and P. microphyUa. 

 It breeds abundantly in company with B. prosopis in mesquite beans 

 {Prosopis glandulosa). We have also bred it on one occasion in large 

 numbers in company with B. salloei from pods of huisache. (Vachel- 

 lia farnesiana) from Victoria, Texas. Four specimens, received from 

 Mr. R. W. Dawson, Lincoln, Neb., were taken on Prosopis velutina 

 at Oro Blanco, Ariz., August 17, 1910. 



No parasites have been definitely reared from this species in our 

 cages, but it is undoubtedly attacked by the typical parasites of other 

 species of Bruchus in the same host plants. 



Horismenus produdus Ashm. was described from specimens reared 

 by C. H. T. Townsend from B. amicus at Las Cruces, N. M. Town- 

 send (Can. Ent., XXVII, 1895, p. 277) records this species and also 

 Eupelmus ( = Cerambycohius) cyaniceps Ashm. as reared from B. 

 amicus. 



Bruchus cruentatus Horn, Trans. Am. Ent. Soc, 1873, p. 325. 



This species was recorded by Riley and Howard (Ins. Life, V, 165) 

 as breeding in the pods of Parkinsonia. We have reared it from pods 

 of Cassia chamcecrista, collected in September at Dallas, Texas, by 

 Mr. W. D. Pierce. At this time all four stages were found. No 

 parasites were reared. 



Bruchus sp. 



This is a small reddish species with abundant gray pubescence. 

 It was found at Marfa, Texas, on June 5, 1908, by Mr. J. D. Mitchell 

 and the author attacking the peculiar bladder-like pods of an Astra- 

 galus (near triflorus). The adults continued to emerge until June 27. 



In this lot of material over 70 per cent of the insects were para- 

 sitized, the species concerned being Eurytoma sp. (undetermined) and 

 an undetermined chalcid, probably a new species, both of which breed 

 singly as primary parasites. 



Bruchus placidus Horn, Trans. Am. Ent. Soc, 1873, p. 341. 



The pods of two low leguminous plants, probably species of Astra- 

 galus, were found on September 23, 1908, at Lampasas, Texas, by the 

 writer to have been abundantly infested by this species. On that 

 date, however, most of the insects had emerged, although one specimen 

 bred from each species of plant served to identify the author of the 

 damage. Of these two belated individuals one was found in the 

 pods at the time of collection and the other emerged on October 5. 

 No parasites were reared. 



Bruchus limbatus Horn, Trans. Am. Ent. Soc, 1873, p. 326. 



A single specimen of this species was reared from a lot of "Tenaza"
