inr)stl,v -vvell-gTown pods. On the other hand the eggs seem 

 to he hiid upon the pods of Frosopis in all stages of growth 

 fnmi the newly set pods to those fidly ripe. It does not 

 show the aversion to laying its egg masses upon exposed 

 surfaces which is so characteristic of B. prosopis when laying 

 ii])(in the ripe pods. 



The eggs from this species when hiid in masses are not 

 readily distinguishable from those of B. prosopis, though the 

 latter seem to be somewhat smaller and more slender. 



There is every indication that in this species, which until 

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

 have an enemy of first importance more adaptable and per- 

 ha])s more serious than either o{ the other species attacking 

 this crop in the Hawaiian Islands. 



Bruchus limbatus (Horn). 



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

 at Waipio, Oahu, a seed of the monkey-pod (Saynmiea saman) 

 bearing eggs of a Bruchid. After bringing this into 

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

 tion (if these led to their determination by the writer as 

 Bnichus Umhatus Horn, an inhabitant of the arid Southwest, 

 Texas. Arizona, South California and Mexico. 



Subsequently the species has been found rather g(>nerally 

 (listi'ibuted in Honolulu and as far along the Kamehameha 

 highway as (^astner. It has not yet been found u])on the 

 windward side of Oahii. 



Besides Sainnncd scunan, this species has been found here 

 bi-eeding naturally in the seeds of Pithecolobium diilce and Al- 

 hizzia lebhel-. while it has been bred experimentally from the 

 seeds of Acacia farneslana and from the pods of Prosopis jiiJi- 

 flora. In the latter case the lu-eeding was secured only after re- 

 peated experimrtit and then only a few adults emerged. It 

 is interesting to note that most of the trees u])on which it has 

 been found breeding in the open here are natives of its 

 Lome country, or at least of the American continent. They
