 ture and forestry. 



Ft vs uncertain how long the species has l)i>en cstahlishcd 

 in the islands bnt certainly its g-eneral spread over this ishuid 

 has occurred since 1917, since the trees of Pithcvolohiiiiii 

 under which extensive collections of seeds were made at that 

 time without finding this weevil, have the fallen seeds in- 

 fested now, 



Cushman has recorded this species (Jour. Econ. Ent. 

 4:498, 1911) as bred from an unknown leguminous cha])- 

 paral at Brownsville, Texas, called '^tenaza" by the Mexicans, 

 and from Siderocarpus flexicaulis. Amundsen reported this 

 species from an imdertermined Mexican legume presumably 

 growing at San Diego, California, called Guamuchile by the 

 Mexicans. This i3lant, judging from his fignre of the pod 

 and seed, is Pithccoloh'nim ungniscatae or some allied species. 



On Dec. 26, 191'.), this weevil was found at work on the 

 fallen pods of Samanea smnan on the government road not 

 far from Pearl City. Eggs had been laid in great numbers on 

 tlie under side of the old pods as they lay on the ground 

 and many others on the seeds as they had been exposed by 

 tlie weathering of the pods. Those eggs so concealed had been 

 l)ut little ]iarasitized liy Uscatia, though a few parasitized eggs 

 were seen. 



Examination of the pods showed them to be in general 

 without syrupy contents. Thej were also somewhat attacked 

 by Pyroderces rdcyi, and one or two other moths, by A rac ce- 

 rium fasicndahiK and one of the species of CarpophUu.'i. 



A well-grown ])od at maturity is about O-S inches long, 

 not quite an inch wide and a half inch thick and contains 

 18-22 or more seeds, each in a separate chamber formed 

 by the firm, rather woody layer of the pod, with layers of 

 the two halves touching each other between the seeds. There 

 is a cellular syru]>y layer between the inner layer and the 

 firm cuticle. Each edge of the pod is thickened and the pods 

 do not dehisce. The seeds are % in. (9 mm.) long, nearly
