borhood oi the shoultltTS. The hind femora are tliin at the base and 

 then gradually dilated to near the apex, quite unlike normal Clytarlus 

 and in fact much more like true Plagithmysus. They arc less like those 

 of tlie former genus tlian are those of the abnormal P. iiiinuiiicins Sharp 

 (F. H. TIT. 646). Tlie hind tibiae and tarsi are very inconspicuously 

 hairy (see remarks al)t>\e under genus Xcsithiiiysits) . Length, 7-10 mm. 



Obs. All the rvpieal Cli/iarJus, as at present known, are 

 attached cither to Acucki Iroa or to Sophora eh nifiophjilln and 

 although many Plaf/itliinijsns feed on these, others affect most 

 varied plants. Those species of Clytarhis which are not at- 

 tached to the Acacias are al)nornial in structure and will prob- 

 ably be separated generically from either genus in the fnture. 



ITab. Oahu. ]\rt. Xaala ; one example (the type ) collected 

 by IT. T. Osl)orn, Sept. 7, 101-3; three examples bred from 

 dead stems of SmlJa.r ('Tuly 0, 1910, Swezey). The descrip- 

 tion is mainly drawn up from the type and best preserved spec- 

 imen. The other three examples all appear to have died 

 before becoming properly mature and are not in good condition, 

 though easily identifiable. 



Proterhixidae. 



Proterhinus swezeyi n. sp. 



A large species with tlie surface of the pronotum and elytra very 

 uneven and tlie erect setae very long, numerous, and conspicuous. Red- 

 dish fuscous, some parts (e.g. the liumeral parts of the elytra) being- 

 more red, others more obscure in color. Legs and antemiae red, the for- 

 mer of paler color than the latter. 



Rostrum of the female short, Itardly longer tlian its greatest width, 

 eyes well-developed and extremely prominent, not dififering much from 

 those of some examples of P. dciiiops, but the head has not the strong 

 transverse constriction of the latter. Tlie rostrum is not polished iit the 

 middle, but minutely sculptured there, and the grooved lines on each 

 side of this owing to the sculpture towards the sides being longitudinally 

 rugose do not stand out distinctly. Antennae slender and of good length ; 

 the scape elongate triangular, and stout ; tlie club slender, 3-jointcd, its 

 basal joint elongate and by no means wide, but being nuich wider at the 

 apex than the preceding joints, the club as a whole is well-marked. Pro- 

 notum strongly and suddenly narrowed anteriorly, the constricted part 

 longer than in most species, witli a large round fovea or impression on 

 each side l)cliind tlie constriction, the part lietweeii tlie foveae sub-
