2 20 FAUNA HAWAIIENSIS 



(ii) At clot lints dysco/eus, sp. nov. 



Nitidus, niger, parum convexus, antennis palpisque rufis, pedibus piceis ; prothorace 

 basin versus angustato, angulis posterioribus obtusis, rotundatis ; elytris minus profunde 

 striatis. Long, -j- — 8 mm. 



Very black, shining. Head broad and sliort. Thorax only very slightly broader 

 than long, a good deal narrowed behind, and usually with a very slight sinuation just 

 before the hind angles. Elytra a good deal sinuate at the sides near the tip, but not 

 appearing truncate, the striae fine, never very deep. Legs rrioderately long and stout, 

 fourth joint of hind tarsus slightly bilobed. 



This differs from A. gracilis by the colour of the legs and the less deeply striate 

 elytra ; the colour of the under-surface is black, the epipleuron not being at all yellow. 



The small series varies a good deal. One specimen — the largest — has the antennae 

 dark. In most of the specimens the third and the fourth, and the fifth and the sixth 

 striae are separately paired, that is, united at the extremity ; but in three others this is 

 not the case, the third and the sixth striae meet together, enclosing the tips of the fourth 

 and fifth. These examples have shorter legs than the previously mentioned specimens, 

 and may possibly prove to be different. The four specimens from West Maui are very 

 small, more deeply striate, and less elongate and shining. There is some doubt as to 

 the locality, as explained in the remarks on A. gracilis; the clue being 357 as in 

 that species. 



Hab. Maui, 3000 ft., in 1900 (Perkins, No. 845). W. Maui .-* (Perkins, No. 357). 



(12) Atelothrus insociabilis, Blk. 

 Anchoinenus insociabilis Blackburn, Ent. Mo. Mag. xv. 1878, p. 121. 



The type is like a very elongate A. dyscoleus: the head is not so broad, the thorax 

 is straighter at the sides, and the elytra longer and rather more convex. It is unique. 



Hab. Maui. Haleakala, 4000 ft. (Blackburn). 



(13) Atelothrus depressus, sp. nov. 



Subdepressus, nitidus, niger, antennis, palpis pedibusque flavis ; prothorace basin 

 versus fortiter angustato ; elytris ad basin angustis, posterius latioribus, ad apicem per- 

 parum sinuatis, sat profunde striatis. Long. corp. 7^ mm., antennae 4^ mm. 



YdiT. fuscipes, var. nov.; antennis pedibusque fuscis, elytris vi.x profundius striatis. 



Thorax small, much narrowed behind, not sinuate at the sides, the base straight, 

 hind angles rather indistinct. Elytra narrow at the base, much disconnected from the 

 thora.x, the apical sinuation just perceptible. Legs slender ; fourth joint of hind tarsus 

 slightly bilobed. Twenty-two specimens.
