COLEOPTERA 135 



angTJstatum vel constrictum, antice setis nonnullis erectis nigris, et ubique squamis 

 nigris albidisque variegatim vestitum, supra vix evidenter sulcatum vel inaequale. 

 Elytra squamis albidis nigrisque variegatim vestita, interstitiis convexis, 2" parum 

 fortiter inaequali, striis parum distincte punctatis, lateribus sat aequaliter rotundatis. 

 Femora nigra plus minus distincte albido-cingulata, tibiis nigro-squamosis, apices versus 

 (circa \ — \ longitud.) squamis pallidis vestitis, ibique rufescentibus. Long, circa 3 mm. 

 (Plate VII. fig. 12.) 



Remarkable for the very narrow long prothorax, which is quite evenly rounded at 

 the sides. The extreme apex of the elytra is covered with pale scales, in front of which 

 is a wide band of black squamosity enclosing a quadrate pale trans-sutural spot, which 

 itself is dark in the centre. In front of this the elytra are variegated with black and 

 pale scales intermixed. 



Hab. Kauai. A single example was taken at Halemanu (4000 ft.).

Acalles decoratus Blackb., Tr. Dublin Soc. iii. 1885, p. 180. 

 H.AB. " Lanai, 2000 ft." " A single specimen " (Blackburn). 



(10) Acalles mauiensis Blackburn. 



Acalles Jtmuiensis Blk., t. c. pp. 179, 181, 254. 



Hab. Maui. " A single specimen beaten from Aleurites triloba, at an elevation 

 of about 4CXX) ft. on Haleakala." (Blackburn.) 



The specimen referred to on p. 181, /. c. is said, p. 254, /. c, to be probably 

 a distinct species. 



(11) Acalles angusticollis Sharp. 



Acalles angusticollis Sharp, Tr. Dublin Soc. in. 1885, p. 179. 



Hab. Maui, Haleakala (Blackburn), where I have myself taken a single example. 

 Minute examples taken on Oahu (var. 7?ii?ior, Shp.) by Mr Blackburn are probably 

 distinct, and almost agree with abraded specimens taken by myself on Lanai. 



(12) Acalles duplex Sharp. 



Acalles diiplex Sharp, /. c. p. 1 78. 

 (Plate VII. fig. 13. ?; fig. 14, ?■) 



Hab. Oahu. Widely distributed on the island. Varies greatly in size, the 

 females apparently not being always of diminutive size as compared with the males.
