650 FAUNA HAWAIIENSIS 



Mr Koebele, in honour of whom the species has been named, secured a small series 

 at various dates. 



Hab. Oahu, mountains near Honolulu. D. S. 



Callithmysus cristahis Sharp. 



' PlagitJimysus cristatus Sharp, huj. op. 11., p. 113, pi. vi. fig. 21. 



A series of 21 additional examples of this interesting but little known species. I 

 remarked, in 1896, on the similarity in shape of the femora of this species with those 

 of the genus Callitlmiysits, and now that C. kocbelei has been discovered, it is clear 

 that cristahts must be transferred to Callithmystis notwithstanding the slender femora 

 of its female. 



In the 21 specimens recently acquired there are six females ; the slender femora is 

 a constant character of this sex of C. cristatus, and the female is also generally much 

 darker in colour than the male ; this distinction is, however, variable, one individual 

 being but little darker than the other sex. The male varies little, except in size. 



Although the dense black hairs at the apex of the hind femora found in C. micro- 

 gaster are absent in C. koebelei and C. cinstatus, yet there is a peculiarity in this spot 

 in both the species in question. In C. koebelei the pubescence there is dark brown 

 instead of whitish, as on the rest of the femur : and in C. cristatus ,? the pubescence 

 in the same place is finer, darker and closer.

Three specimens of this species were found on Oahu by Mr Perkins in 1900 and 

 1 90 1. It is widely distributed in the East and, as it is of large size, has probably been 

 recently introduced. It is only like Prosoplus bankii, but is more than twice the size. 



Hab. Oahu (Perkins). Java, Aden, etc. etc. 



Fam. CURCULIONIDAE'. 



(1) Rhyncogonus sharpi, sp. nov. 



Black or pitchy black, shining, legs often more or less reddish, tarsi always rufescent, 

 antennae black or reddish, whole insect with appressed squamous hairs, in fresh speci- 

 mens flavescent about the eyes and at the sides of the pronotum.
