40 Mr, D. Sharp on some 



Mr. Blackburn found a small colony of this species 

 among the remains of a decayed tree on the mountains 

 near Honolulu. The two specimens before me are not in 

 good condition, and show no sexual characters, except, 

 perhaps, that the head appears more distinctly punctured 

 in one than it is in the other. 



Diestota latifrons, n. sp. Depressa, fusca, opaca, an- 

 tennarum basi pedibusque rufis ; antennis articulis nullis 

 transversis ; capite thoraceque fere impunctatis, hoc elytris 

 angustiore basin versus angustato ; elytris subtiliter punc- 

 tatis. Long, fere 3 mm. 



Antennas longer than head and thorax, a little thickened 

 towards the extremity, ord joint as long as the 2nd, 4 — 10 

 each about as long as broad. Head large, a good deal 

 narrowed behind the prominent eyes, its surface very dull, 

 but without distinct punctuation. Thorax a good deal 

 narrower than the elytra, transverse, but not very strongly 

 so, its greatest width much in front of the middle, thence 

 distinctly narrowed to the base ; its surface is very dull, 

 but only very indistinctly punctured. Elytra much longer 

 than the thorax, dull, finely punctured. Hind body 

 scarcely visibly punctured, rather dull, the apical segments 

 a little more shining. Legs red. 



This species has the antennte more elongate than any 

 of the allies, and its middle cox^ are more approximate. 

 The only individual I have seen is, I think, a female. 

 The mesosternum, I believe, is without carina. 



Found on Freycinetia, in the mountains of Kauai. 



Diestota palpalis, n. sp. Depressa, fusca, opaca, pedi- 

 bus testaceis, antennis articulis penultimis transversis ; 

 capite thoraceque fere impunctatis, hoc basin versus 

 leviter angustato ; elytris subtiliter punctatis. Long, 

 fere 3 mm. 



Antenufe not longer than head and thorax, 3rd joint 

 not quite so long as 2nd, joints 7 — 10 transverse. Head 

 rather large, without visible punctuation. Thorax nar- 

 roAver than the elytra, transverse, but not strongly so. 

 Elytra a good deal longer than the thorax, finely pimc- 

 tured. Hind body very sparingly and indistinctly punc- 

 tured, not nearly so dull as the other parts. Mesosternum 

 Avithout carina ; middle coxte only moderately distant. 



The species is very closely allied to the preceding one.
