Bruchidae Eecent IinniioTants Into Hawaii. 



]^o species of Bruchidae are then members of endemic fau- 

 na of the Hawaiian Islands but at least eight sisecies belonging 

 to three genera have already become established here and sev- 

 eral have been intercepted in quarantine inspection. 



The following species have previously been reported as oc- 

 curring in the Hawaiian Islands: Bruchus obtectus Say, the 

 common bean weevil; Bruclius cliineyisis Linne, the cowpea 

 weevil; Brucliiis quadrimacidatus Fabricius, the four-spotted 

 bean weevil; Bruchus prosopis Leconte, the niesquite or alga- 

 roba weevil ; Caryohorus gonagra Fabricius, the tamarind wee- 

 vil. To these may now be added (1) Bruchus pruininus Horn; 

 (2) an undetermined Br^uchus of the group of B. chinensis and 

 B. quadrimaculatus closely related to Bruchus ornatus Bohe- 

 man which may for convenience be termed the Dolichos weevil ; 

 and (3) a small Spermophagus or Zabrotes, as yet undeter- 

 mined but perhaps identical with Spermophagus (Zabrotes) 

 pectoralis Sharp. Aside from these Bruchus pisorum Linne 

 and B. rufimanus Boheman occur commonly in imported peas 

 {Pisum saUvum) and broad or horse beans (Vicia faba) re- 

 spectively.* 



Table of Hawaiian Brucliidae. 



The recognition of these species may perhaps be facilitated 



by the following table: 



1. Hind femora slender, without teeth of any kind, hind 

 tibiae with w^eak spinules within and two stout movable 

 spines at the apex. A small, compact species, the female 

 with two whitish transverse spots of pubescence on the 

 sides of the elytra near the middle Zabrotes. 



*In discussing these species I have preferred, in the absence of any 

 general acceptance of any one set of proposed emendations of the nomen- 

 clature of the species and genera and lacking the necessary time or 

 literature to arrive at independent conclusions, to use the terms in gen- 

 eral use. At the same time I fully recognize the desirability of separat- 

 ing the natural genera confused under the old genus Bruchus and also 

 the necessity of basing coleopterous nomenclature on the law of priority.
