Brucliidae Recent IinniigTants Into Hawaii. 



No species of Brucliidae are then members of endemic fau- 

 na of the Hawaiian Islands but at least eight species 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 : Brachus ohtectus Say, the 

 common bean weevil; Briichus chinensis Linne, the cowpea 

 weevil; BrucJius quadrlmacidatiis Fabricius, the four-spotted 

 bean weevil; Bruchit.s pr-osopis Leconte, the mesquite or alga- 

 roba weevil ; Caryohorus gonagra Fabricius, the tamarind wee- 

 vil. To these may now be added (1) Brucltiis pruiiiinits Horn; 

 (2) an undetermined BrucJius of the group of B. chinensis and 

 B. quadriniaculatus closely related to Bniclius ornatus Bohe- 

 man which may for convenience be termed the Dolichos weevil ; 

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

 mined but perhaps identical with Spcrmophagus (Zabroles) 

 pectoralis Sharp. Aside from these BrucJius pisorum Linne 

 and B. rufimanus Boheman occur commonly in imported peas 

 (Pisum saiiviim) and broad or horse beans (Vicia faha) re- 

 spectively.* 



Table of Hawaiian Brucliidae. 



The recogTiition of these species may perhaps be facilitated 



by the following table: 



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

 tibiae with weak spinules within and tw^o stout movable 

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

 with two W'hitish transverse spots of pubescence on the 

 sides of the elytra near the middle Zahrotes. 



* In discussing these species I have preferred, in the ahsence 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.
