2i8 FAUNA HAWAIIENSIS 



(6) Atelothrus lougulns, sp. nov. 



Sat elongatus, nitidus, niger, antennis, palpis pedibusque flavis ; prothorace basin 

 versus minus fortiter angustato ; elytris sat profunde striatis, apicibus parum sinuatis, 

 sat prolongatis. Long, jh mm. 



Closely allied to A. politus, but rather smaller, with the elytra only obsoletely sinuate 

 at the tip, and the abdomen not variegate in colour. Almost equally close to A. depressus 

 and A. g7'acilis, but with the elytra more prolonged at the tips, and the fourth joint of 

 the hind tarsus not bilobed, but formed as in A. politus. Three specimens. 



Hab. Maui (Perkins). The same doubt exists as to the locality of this species 

 as does to that of L. gracilis ; but the habitat is probably " West Maui mountains, 

 4000 ft., IV. 1894," one of the specimens bearing that label. 



(7) Atelothrus steiiopus, sp. nov. 



Nigerrimus, politus, pedibus fuscis, antennis palpisque rufo-obscuris ; prothorace sat 

 elongato, basin versus sat angustato ; elytris sat profunde striatis, apice modice sinuato ; 

 tarsis posterioribus gracilibus, articulo quarto haud lobato. Long. 8 mm. 



This is not likely to be confounded with any species except A. filipes, but A. stcnopus 

 is a little larger and has a decidedly longer prothorax. Only two specimens, both males, 

 have been found. 



In 1900 Mr Perkins found on Haleakala, 3000 ft., a third specimen that agrees 

 with the two types so well that I cannot treat it as distinct, although it has no seta on 

 the thorax and is therefore to all intents and purposes a Metromenus. There is no 

 species of Metromenus to which this specimen can be assigned, and therefore I at present 

 treat it as an aberration or sport of A. stenopus. 



Hab. Maui, Perkins. Haleakala, 5000 ft., April 1894, May 1895. 



(8) Atelothrus filipes, sp. nov. 



Nigerrimus, politus, pedibus fuscis, antennis rufo-obscuris, basi palpisque dilutiori- 

 bus ; prothorace minus elongato, basin versus minus angustato ; elytris sat profunde 

 striatis, apice parum sinuato ; tarsis posterioribus gracilibus, articulo 4to haud lobato. 

 Long. 6^ — 7 mm. 



The thorax is comparatively little narrowed behind ; it is slightly sinuate at the 

 sides behind, the hind angles a little obtuse and rounded, the side-margin fine, but little 

 elevated. The colour of the elytra is very black with a very slight green reflection. 

 Compared with the dark-legged variety of A. depressus, the species is readily distin- 

 guished by the shape of the thorax, which is less elongate and less narrowed behind, and 

 by the rather more slender hind legs. Twenty-two specimens. 



Hab. Lanai (Perkins). Halepaakai, July 1894; Mts. Koele, Jan. and Feb, 1894.
