mostly well-gTown puds. On the other hand the eggs seem 

 to l)e laid upon the pods of Prosopis in all stages of growth 

 from the newl}' set pods to those fnllv ripe. It does not 

 show the aversion to laying its egg masses upon exposed 

 suriaces which is so characteristic of B. prosopis when laying 

 upon the ripe pods. 



The eggs froui this species when hud in masses are not 

 readily distinguishable from those of B. prosopis, though the 

 latter seem to he somewhat smaller and more slender. 



There is every indication that in this species, wdiich until 

 last year was not known to attack the seeds of Prosopis, we 

 have an enemy of first importance more adaptable and per- 

 hiips more serious than either of the other species attacking 

 this crop in the Hawaiian Islands. 



Bruchus limbatus (Horn). 



In June, 1919, Mr. Swezey and Mr. Pemberton found 

 at AVaipio, Oalui, a seed of the monkey-pod (Samanea saman) 

 bearing eggs of a Bruchid. After bringing this into 

 the lal)oratory, four adults emerged from the seed. Examina- 

 tion of these led to their determination by the writer as 

 Brurlii4s Jimhafiis Horn, an inhabitant of the arid Southwest, 

 Texas, Arizona, South California and Mexico.

JJesides Sania/nca sfiiiian. this s])ecies has been found here 

 breeding naturally in the seeds of Pithccolobiinn diiJrc and .4^ 

 hizzia lehhel-, while it has been bred experimentally from the 

 seeds of Acacia farnesiaiui and from the pods of Prosopis jali- 

 fJora. In the latter case the breeding was secured only after re- 

 peated experiment and then only a few adults emerged. It 

 is interesting to note that most of the trees upon which it has 

 been found breeding in the open here are natives of its 

 Lome cotmtry, or at least of the American continent. Thev
