COLEOPTERA 133 



In this species tlie elytra except for the well-marked transverse white spot, beyond 

 the middle, are nearly entirely clothed with black scales, but there is an indication 

 of an obscure paler area on each side extending from behind the shoulders towards the 

 suture. The sides as seen from above are simply rounded from the shoulders, and 

 not at all irregular. The second and fourth interstice are evidently more strongly 

 raised than the first and third, the first being hardly, and the third but little convex. 

 The second is slightly unevenly raised, and is densely clothed with erect black scales 

 at the base and again just before the region of the transverse white spot, which 

 accentuate the appearance of inequality. The most conspicuous feature of the species 

 is the smooth red lanceolate space lying between the inner ridges of the prothorax, and 

 the entirely black appressed scales of the femora. 



Hab. Hawaii. A single example taken at Kilauea. 



(5) A calks fraier, sp. nov. 



Praecedenti simillimus, nigro-squamosus, rostro rufo, antennis, tarsisque testaceis. 

 Pronotum squamis ferrugineis supra maculatum, sulco medio plagam rubram haud 

 ferente. Elytra plaga ferrugineo-squamosa fasciam latam formante ornata, apice 

 squamis ferrugineis variegato. Femora media distincte pallide cingulata. Long, 

 (rostr. excl.) circa 3 mm. 



Very closely allied to A. melanolepis, but the thorax is without the red smooth 

 lanceolate area between the inner ridges, and is ornamented above with ferruginous 

 spots, and the elytra have a large lateral band of similarly coloured scales, extending 

 from behind the shoulders, and forming a wide transverse fascia which is less distinct 

 towards the suture ; their apex is also variegated with paler scales. All the femora 

 have a pale band of appressed scales at the base and another about the middle. 



A single example from Molokai is very similar to the above but the pale scales 

 of the thorax and elytra are greyish, the transverse fascia of the latter less defined, 

 the antennae, rostrum and tarsi much less clearly coloured, and the thorax evidently 

 shorter. The difference in the latter respect is probably sexual, but I suspect that the 

 two forms are distinct, though very closely allied. 



Hab. Maui, Haleakala (5000 ft.); one example. Van on Molokai (4000 ft.); 

 one example.

 capite antico pallide squamosa. Pronotum angustum, elongatum, antice constrictum,
