This species is rather smaller and narrower than our 

 European O. mflata, from which it also departs, by its 

 more prominent eyes, the more Gyrophrenoid shape of the 

 prothorax, and stouter legs, as well as by its colour and 

 sculpture. 



Mr. Blackburn has found two individuals of this 

 species in flowers in the island of Oahu ; although the 

 two localities in Avhich they were found are Avidely sepa- 

 rated, in each case the elevation was about 3,000 feet. 



Oligota glabra, n. sp. Parum elongata, nigra, nitida, 

 glabra, elytris parcissime punctulatis, antennis pal])isque 

 testaceis, pedibus fuscis, abdomine ad basin angustato. 

 Long. 1^ mm. 



Antennre yellow, 1st and 2nd joints elongate, 3rd, 4th 

 and 5th slender, the 3rd rather longer than either of the 

 other two, 6th just a little broader than the preceding one, 

 longer than broad, 7th to 9th each distinctly broader than 

 the preceding one, the 7th about as long as broad, the 9th 

 rather transverse, 10th large, quite as long as the two pre- 

 ceding together. 



This species appears to be closely allied to the preceding 

 one, it is a little larger, and the antenna} are rather more 

 elongate. The hind body appears more developed, and 

 owing to the basal segments being narrower than the fol- 

 lowing ones, is but little retractile. It is a little larger 

 than the Euro])ean O. injlata. 



Found rarely by beating trees on Mauna Loa, and 

 Mauna Kea, Hawaii. 



Oligota mutanda, n. sp. Sat elongata, nigra nitida, 

 elytris sat crebre pun ctatis( antennis?); abdomine parallelo 

 quara thorace conspicue angustiore. Long. 1 1 mm. 



Head rather small, but with the eyes distinct and con- 

 vex ; thorax very strongly transverse, about as broad as 

 the elytra, and closely applied to them, the surface very 

 finely punctured and pubescent. Elytra longer than the 

 thorax, somewhat finely and not closely, quite distinctly 

 punctured. Hind body rather narrow, and nearly parallel, 

 but little broader than the head, and a good deal narrower 

 than the thorax and elytra, rather convex and shining, 

 but finely punctured and with a scanty pubescence, the 

 basal segments rather deeply impressed at the base. Legs 

 rather elongate and slender, nearly black.
