COLEOPTERA 557 



pubescence and sculpture are not so slight as in brevicollis, and the surface is therefore 

 less shining. One specimen. 



Hab. Kauai, mts. Waimea, 4000 ft. vi. [894 (Perkins). 



(6) Oligota {Gnatlioligota}) parax, sp. nov. 



Sat lata, nigricans, antennis palpis pedibusque testaceis; pube suberecta vestita, 

 fortiter parce punctato; antennis minus abrupte clavatis. Long, i^ mm. 



This differs from O. bi-evicolUs by its narrower form, and by the different shape of 

 the antennae, the 3rd, 4th, 5th and 6th joints being not transverse, the 7th slightly 

 transverse, and the 8th moderately so. One specimen. 



Hab. Molokai, high forest (Perkins). 



(7) Oligota [Giiafholigota}) c.xiraiica, sp. nov. 



Sat elongata, subparallela, baud nitida, fortiter punctata, longius sed baud dense 

 pubescens, picea, antennis palpis pedibusque testaceis, illis clava tere abrupte quadri- 

 articulata. Long, i^ mm. 



This is a very peculiar species, not likely to be confounded with any other ; the last 

 joint of the palpus is elongate, very slender and quite parallel, and contrasts strongly with 

 the penultimate joint which is rather broader than usual in the Hawaiian species: the 

 head is not pointed in front, and is coarsely punctured. The thora.x is very short, and 

 narrowed towards the base, rather than towards the front ; the elytra are longer than the 

 thorax, the abdomen elongate and narrow, slightly but distinctly narrower in front, 

 though not at all rounded at the sides. The legs rather stout. Five specimens. 



I am not at all clear as to the relation of this form to the other Hawaiian Oligotinae. 

 The middle coxae are less widely separated than usual, the intercoxal suture between 

 them very strongly marked. The mandibles are I believe longer than normal, though 

 not so peculiar as in O. laiifroiis. On the whole I think it best placed at present in the 

 subofenus Gnatholiiiota. 



Hab. Molokai, highest mountains, ix. 1893 (Perkins). 



Oligota, Nesoligota subg. nov. 



The species of this genus have polished integuments, and but little sculpture on the 

 abdomen; these characters distinguish the species from Oligota, s. str., and Holobiis. 

 From Gnatholigota the quite different shape of the head is sufficiently distinctive, 

 without reference to the mandibles. The head is only about half as broad as the elytra, 

 and looks somewhat acuminate in front. The "rounding" of the abdomen at the sides 

 arises from the fact that the extreme basal segments are distinctly narrower than those 

 that are antepenultimate.
