COLEOPTERA 561 



them has the clypeus picescent. This individual makes some approximation to O. 

 frontalis. One of the specimens is smaller, has the \(i<y?, darker, and the punctuation 

 of the elytra more distinct. It is doubtful whether it may not be another species. 

 Hab. Hawaii ; Hualalai, 5000 ft. 5. viii. 1S92 and ix. 1900 (Perkins). 



(16) Oltgota frontalis, sp. nov. 



Nigerrima, nitida, capite testaceo vertice fusco, pedibus fusco-testaceis, antennis 

 flavis. Long. \^ mm. 



Closely allied to O. scripta, but with finer sculpture and readily distinguished by 

 the yellow head ; the antennae are short, even the 7th joint being distinctly transverse. 

 Two specimens. 



A third specimen, from back of Tantalus, is entirely brownish yellow, with the front 

 of the head paler. It may be another species, or it may be an immature variety. 



Hab. Oahu. Waianae mts. 2000 — 3000 ft. 11. 1896; and var. .^ back of Tantalus, 

 VII. 1900 (Perkins). 



(17) Oligota adpropiiiquans, sp. nov. 



Nigerrima, nitida, minuta, parce punctata, pedibus vix fusco-testaceis, antennis 

 palpisque flavis. Long. i:|; mm. 



I separate a single individual from O. iiisolita on account of its narrower more 

 parallel form. I see no other distinction of importance. 



Hab. Oahu, Waianae mts. 2000 — ^3000 ft. 11. 1896 (Perkins). 



(18) Oligota insolita, sp. nov. 



Nigerrima, nitida, minuta, brevis, minus angusta, parce punctata, pedibus fusco- 

 testaceis, antennis palpisque flavis. Long. \\ mm. 



This tiny insect, though closely allied to O. frontalis, is doubtless quite distinct. 

 It has the head black, and is of shorter and broader form. The 8th joint of the antenna 

 is decidedly but not strongly transverse. Two specimens. 



Hab. Kauai, Makaweli, 2500 ft. 11. 1897 (Perkins). 



(19) Oligota gymnusa, sp. nov. 



Nigra, subopaca, minus parce punctata, longius pubescens, antennis flavis. Long, 

 i^ mm. 



This, though looking very distinct from O. scripta, is really closely allied ; it is of 

 much broader form, and the sculpture is much denser, which gives it a dull appearance. 

 The elytra are rather longer than usual, and the tarsi short. The 8th and 9th joints of 

 the antennae strongly transverse. 



Hab. Lanai, 2000 ft. i. 1894 (Perkins).
