COLEOPTERA 389 



The feet are formed verv much like those of D. bo7ivoiilou-i, the terminal ioint beino- 

 shorter than in D. agriotoides. 



The two specimens fotind in Hawaii are discordant in size ; it is possible that 

 the form may prove to be not sufficiently distinct from D. bonvoidoiri. Until more 

 specimens of these difficult forms can be examined it is not possible to speak with any 

 confidence. 



The three specimens from Honolulu agree neither with this species nor with 

 D. bonvoii/oiri. but apparently are nearest to D. ardiius. of which I have labelled them 

 as varieties. The thorax is shorter, more strongly punctured and less narrowed in front. 



Hab. Hawaii : Kona, 3000 ft. viii. 1894 : Olaa, ix. 1896 (Perkins). — The variety 

 from Oahu was found on the mountains near Honolulu in August, 1900 (no. 785, 

 Perkins). 



(6) Droinacolus aiiicus, sp. nov. 



Elongatus, angustus, postice acuminatus, thorace elytris paulo latiore, fusconiger, 

 dense subtiliter punctatus, pubescentia pallida : antennis pedibusque flavis, illis elongatis. 

 Long. 5^ mm., lat. vix if mm. 



Closely allied to D. bonvoitloiri ; of all the species the narrowest and most wedge- 

 shaped, the thora.x being perceptibly broader than the elytra. The antennae are rather 

 slender, and the terminal two and a half joints extend beyond the angles of the thora.x. 

 The punctuation of the thorax is less dense and coarse than it is in D. bonvoitloiri. 

 The fourth joint ot the antennae is a little longer than broad, the terminal joint elongate. 

 Only one .specimen was found, and as I cannot place it at present with either of the 

 other species I treat it as distinct, though it is far from improbable that it may prove to 

 be connected with either D. agriotoides or D. bonvoidoiri . 



Hab. Hawaii: Kona, 3000 ft. August, 1894 ("O- i4-> Perkins). 



(7) Droinacolus sordidns, sp. nov. 



Fusco-terrugineus, dense subtiliter punctatus et pubescens, antennis elongatis. 

 Long. 5 J — 6 mm. 



This is broader than D. bonvoitloiri and less acuminate behind, darker in colour, 

 much more finely punctate, with longer antennae, the setae and pubescence of which are 

 more distinct. The antennae extend back as far as the hind margin of the meta- 

 sternum, their third joint is elongate, not greatly shorter than the basal one, fourth 

 much longer than broad. The legs are red, more or less infuscate ; the front tibiae 

 broad, and the second and third joints of the front feet are much smaller than the fourth. 

 The antennal grooves are rather broader and less sharp and definite than they are in 

 D. bonvoitloiri. Two specimens. 



Hab. Oahu, Kaala mts. 2000 ft. January, 1893 (no. 34, Perkins).
