2 54 FAUNA HAWAIIENSIS 



M. niontivagiis in its general appearance bears a great resemblance to the Australian 

 and New Zealand species Cyclothoraxjnsularis, and, as noticed above, was recorded by 

 Karsch as being actually the antipodean species. I find, however, that the wings in it 

 are as fully aborted as they are in the other Hawaiian forms, whereas they are perfectly 

 developed in the antipodean forms. Whether the Australian and New Zealand species 

 are really one, as has been supposed, only indirectly concerns us, but I may mention 

 that I believe they will prove to be distinct.

This is undoubtedly closely allied to M. iiioiitwagits, though its recognition is 

 extremely easy by " facies " when the two are known. AI. pele is a little narrower and 

 considerably more conve.x transversely, its legs and antennae are considerably stouter, 

 and are more red than yellow, the legs are often blackened on the femora and tibiae, 

 and the surface is intensely black, with a glassy appearance : the thorax is much narrower 

 and more convex, and the hind angles are less prominent : the punctures of the elytra 

 are larger and deeper. Although J/, luoiitivagus is variable, the variation does not tend 

 towards M. pele, and there is no example about which a mistake could be possible. 



M. pele is apparently rare, but has been found several times at the crater of Mauna 

 Loa, called Kilauea, in August and September.

(25) Mecyclothorax bevibidicus, sp. nov. 



Robustus, niger, elytris obscure aeneis, antennarum basi, palpis pedibusque testaceis, 

 his plus minusve fuscescentibus ; prothorace transverso, basin versus angustato, haud 

 sinuato, angulis posterioribus obtusis ; elytris profunde striatis, striis integris, crenato- 

 punctatis. Long. ^\ mm. 



A very distinct species ; differs from A/, pele by the deep striae of the elytra, which 

 extend from base to tip, and from M. robustus by the deep striation and the unsinuate 

 sides of the thorax. The elytra are very broad, about twice as broad as the thorax, and 

 their eight deep striae are also rather broad, and are very deep even at the tip, they are 

 of a brassy colour, but dull. The thorax is a good deal narrowed behind, the anterior 

 impression is obliterated, and the median channel is not deep, and does not extend to 

 the base. Eighteen specimens.
