COLEOPTERA 391 



very distinctly longer, subequal but each slightly longer than its predecessor. Thorax 

 with a slight depression causing the hind angles to appear to be slightlv flattened, its 

 punctuation \ery fine. Elytra distinctly striate, but with only very indistinct punctuation. 

 Under surface very slightly punctuate. Legs and antennae clear yellow-red. This is 

 almost as near to D. pimcticollis and D. so/iiariiis as it is to bonvoiiloiri. The type 

 specimen is nearer to bonvoiiloiri, but a second example (which I have treated as a 

 variet)-) is more like D. piuicticollis. 



Hab. Hawaii: Kona, 4000 ft. in 1S97 (Perkins). The variety is from Kilauea, 

 August, 1896 (no. 656, Perkins). 



(11) Droiiiacolns pnncticollis, sp. nov. 



Angustus, nigricans, antennis pedibusque rufis, flavo-pubescens, haud nitidus ; 

 thorace dense fortiter punctato, elytris striatis ; antennis sat elongatis. Long. 5-^ — 6 mm. 



This species has a coarser and closer punctuation on the thorax than any of the 

 others : though ot narrow lorm it is not acuminate behind like D. bonvoiiloiri. The 

 antennae have about one joint e.xtending beyond the hind angle of the prothorax : the 

 striation of the elytra is a little more distinct than usual. The fourth joint of the 

 antenna is only slightly longer than broad, and the terminal joint is moderately long. 

 The species has a sordid appearance, and the colour is indefinite, both legs and antennae 

 being more or less infuscate. The sides of the mesosternal cavity are narrow, and the 

 tarsi are rather slender. 



We have received nine specimens of this species, and they agree sufficiently in 

 their characters to make me think the species is undoubtedh- distinct from an\' other. 



Hak. Hawaii. Kilauea, August, 1896 (6 specimens, no. 656); August, 1895 

 (3 specimens, nos. 532, 686, Perkins). 



(12) Droinaeoliis iiiixfiis. sp. nov. 



Angustus. rufus, antennis plus minusve nigricantibus, tiavo-pubescens, haud nitidus, 

 thorace dense fortiter punctato, elytris striatis ; antennis sat elongatis. Long. 4 — 5 mm. 



The coarse extremely dense sculpture of the thorax allies this species to D. piuicti- 

 collis. But I do not think the two forms will be tbund to be connected. Besides the 

 differences in size and colour (which are perhaps of little importance), there is a differ- 

 ence in torni ; D. iiiixtits is more con\'ex and shorter. 



There are only three specimens of this species ; two. very much alike, have the 

 antennae in larger part black : the third specimen is smaller, immature ami much 

 injured ; it has the antennae entirely yellow, possibly owing to its immaturity. 



Hab. Molokai : mountains, 4000 ft. May 17th, 1893 (no. 184, Perkins).
