borhood of tlie shuuldcrs. 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 are less like those 

 of the former genus than arc those of the abnormal P. iinmundus Sharp 

 (F. W. Ill, 646). The hind tibiae and tarsi are very inconspicuously 

 hairy (see remarks alwve under genus Ncsithiiiysus) . Length, 7-10 mm. 



Obs. All the typical Clytarhis, as at present known, are 

 attached either to Acacia hoa or to Sophora chrysopliyJla and 

 althongh many Plagithmysus feed on these, others aflfect most 

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

 tached to the Acacias are abnormal in strnctnre and will prob- 

 ably be separated genericallj from either genns in the futnre. 



Hab, Oahn, Mt. Kaala; one example (the type) collected 

 by IT. T. Osborn, Sept. 7, 1913 ; three examples bred from 

 dead stems of Sniilax (Jnly 9, 1916, Swezey). The descrip- 

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

 imen. The other three examples all appear to have died 

 before becoming properly matnre and are not in good condition, 

 thongh easily identifiable. 



Proterhinidae. 



Proterhinus swezeyi n. sp. 



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

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

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

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

 mer of paler color than the latter. 



Rostrum of the female short, hardly longer than its greatest width, 

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

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

 transverse constriction of the latter. The rostrum is not polished in 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 ; the club slender, 3-jointed, its 

 basal joint elongate and by no means wide, but being much 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, with a large round fovea or impression on 

 each side liehind the constriction, tlie part between tlie foveae sub-
