560 FAUNA HAWAIIENSIS 



(14) Oligota {Nesoligota) bicolor, sp. nov. 



Nitida, parcissime subtilissime pubescens fere glabra, capite thoraceque rufes 

 centibus, abdomine elytrisque nigris, antennis pedibusque dilute flavis. Long, i^ mm. 



Closely allied to O. polita, but readily distinguished by the bright coloration, an 

 its more slender form. There is no elevated carina between the middle coxae. Five 

 specimens. 



Hab. Oahu. Konahuanui Ridge, xr. 1900; back of Tantalus, xii, 1900; (Perkins). 



Oligota, s. str. 



The species, 14 — 19, placed here at the head of Oligota s. str. are quite aberrant, 

 and should probably be separated. From O. mutanda on to the end of the genus, the 

 species are more like the European forms, and may possibly prove really congeneric 

 therewith. 



(15) Oligota script a, sp. nov. 



Nigerrima, nitida, parce punctata et pubescens, pedibus sordide testaceis, antennis 

 flavis. Long. lA mm. 



This species is remarkable by the highly developed minute sculpture of scratches, 

 which it exhibits on the head, thorax, and elytra, in addition to the remote and distant 

 strong punctures ; this fine sculpture forms a dense minute network. On the abdomen 

 this sculpture is less close and less definite : at the base of the second and third segments 

 of this part there are a number of raised longitudinal plicae in the transverse basal 

 depression. The antennae are moderately long, very pale yellow, the terminal joint 

 slightly infuscate, the 7th joint not transverse, the 8th and 9th not strongly transverse. 



This is one of the most obscure and difficult of the species, and careful collection 

 and observation, with field notes, are requisite before the question of specific identity 

 can be settled. It is possible that there may be difference in the sexes, but as there are 

 no external characters at present known by which the sexes can be discriminated, this 

 point must also stand over. 



Hab. Kauai, Maui, Hawaii. — Kauai, Koholuamano ; Kauai, 4000 It. x. 1895 ; high 

 plateau, 8. ix. 1896 (Perkins). — Maui, Haleakala, 5000 ft. x. 1896.7— Hawaii; Kilauea, 

 VII. 1896 and VIII. 1896 (Perkins). 



Oligota scripta, var. laetior, var. nov. 



The specimens of O. scripta from Kauai and Kilauea in Hawaii agree fairly well, 

 but a short series from Hualalai in Hawaii can be distinguished by the more polished 

 surface, the finer minute reticulate sculpture and the more effaced and scanty larger 

 punctures of the prothorax. They are however so very similar to what I have considered 

 the typical form that I think it best to treat them at present merely as a variety ; one of
