5/10 in. (7 mm.) wide and 9/32 (5.5 mm.) thick, shaped 

 like a grain of corn as seen flat and thicker before the mid- 

 dle. There is no apparent albumen and the seed coat is 

 thickest at the edge. The emergence holes of the weevils 

 lire therefore generally found along the edge of the seed. 



From 69 seeds examined from a lot in which the weevils 

 had been breeding for three generations 193 weevils had bred 

 as follows :

Caryoborus gonagra (Fabricius). 



While the eggs of Bruchus prosopis are laid early enough 

 in the development of the algaroba pods that the ])rinci])al 

 damage is completed before the cro]) is harvested, this s])e-

Sallaei. 



On Xoveudjer 25, newly emerged Bnirlius sallaei females 

 were ])laced with a pod of Acacia farncsiana and left until 

 about 10 a. m., November 27, when many eggs had been 

 laid scattered on one surface. This pod was then placed in 

 a test tube with newly emerged Uscana from eggs of Cnry- 

 ohorus. By 12 m. the females were seen ovipositing au<] 

 mating was in progress.
