than 2nd, the pennltimate joints distinctly transverse. 

 Head short and broad, densely, deeply and coarsely punc- 

 tnred. Thorax distinctly transverse, narrower than the 

 elytra, a little narrowed towards the base, its surface 

 densely and coarsely punctnred. Elytra considerably 

 longer than the thorax, densely and not altogether finely, 

 yet indistinctly, pnnctured. Hind body slightly but dis- 

 tinctly constricted at the base, its surface dull, obscurely 

 punctured, the lateral margins broad, the pubescence 

 somewhat distinct. 



Of this species I have seen only a single female ; the 

 punctuation of the upper surface easily distinguishes it 

 from its allies ; the middle coxa3 are rather widely separated, 

 and the mesosternum is finely carinated along the middle. 



Found by beating in a mountain forest near Honolulu. 



Diestota rufescens, n. sp. Subdepressa, opaca, rufes- 

 cens, elytris fuscis, basi rufiBscente, antennis versus apicem 

 infuscatis ; capite thoraceque obsolete punctatis. Long. 

 3 mm. 



AntennjB moderately short, not very stout, distinctly 

 thickened towards the extremity, of a reddish colour, 

 infuscate towards the extremity ; 3rd joint a little smaller 

 than 2nd, 4th, but little smaller than the following ones ; 

 these are not transverse, the 10th being, in fact, the only 

 one that is distinctly transverse. Head broad and short, 

 very dull, but without any distinct punctuation. Thorax 

 strongly transverse, a good deal narrower than the elytra ; 

 its greatest width in front of the middle, thence a good 

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

 punctuation extremely fine and indistinct. The elytra 

 are much longer than the thorax, their apical portion is of 

 a smoky or blackish colour, their basal portion reddish, 

 their punctuation is dense and fine, but not so fine as that 

 of the head and thorax. The hind body is rather large 

 and broad, scarcely at all narrowed at the base ; it is less 

 dull than the anterior parts, the basal segments are some- 

 what closely, the apical ones are more sparingly, punc- 

 tured. The legs are reddish-yellow. 



I have seen but a single individual ; it is a male, the 

 last dorsal plate terminates on each side in a sharp, 

 slender, slightly-curved tooth, and between these are 

 seven fine short crenulations. The middle coxaj in this 

 species are rather widely separated, but the mesosternum 

 appears destitute of a carina. Although on account of the
