9 (a). Acalles truquii, sp. n. (Tab. IX. figg. 20, 20 a.) 











Oblong-ovate, narrow, black, the antennae, tip of the rostrum, and tarsi ferruginous ; variegated above with 

 narrow, scattered, brown and ochreous scales, the latter becoming much more abundant on a common 

 v-shaped area at the commencement of the apical declivity of the elytra, the head densely clothed with 

 whitish scales on the vertex, the legs subannulate. Head and rostrum densely punctate, the latter 

 a little shorter than the prothorax and subcarinate. Prothorax about as long as broad, constricted and 



subtubulate in front, the disc depressed anteriorly and down the middle, the sides parallel at the base ; 

 coarsely, rugosely, confidently punctate, and with an abbreviated arcuate median carina. Elytra oblong, 

 a little wider than the prothorax, compressed at the sides towards the apex, and with the apical portion 

 somewhat narrowly produced, the humeri angularly projecting in front ; nodose and irregularly seriato- 

 f oveate, the uneven interstices here and there bare and impunctate, the denser and paler vestiture mainly 

 confined to the oblique area on the apical declivity, the suture granulate at the base. Beneath sparsely 

 foveato -punctate ; ventral segments 2 and 5 subequal in length, 2 nearly twice as long as 3 and 4 united,

prothorax, and the nodose, foveolate elytra, with a common v-shaped, 

 -squamose area towards the apex and the humeri angularly projecting in front.

9 (b). Acalles anchonoides, sp. n. (Tab. IX. figg. 21, 21 a.) 



ong-ovate. black, the antennae and tarsi ferruginous ; clothed with a few widely scattered narrow ochreous 

 scales, the depressions of the surface more or less coated with a mud-like incrustation. Head densely, 

 finely punctate ; rostrum nearly as long as the prothorax, rugosely punctured at the base, for the rest 

 sparsely, minutely punctate. Prothorax nearly as long as broad, rounded at the sides, constricted and

narrowed in front, subtruncate at the base ; coarsely, confidently punctate, the disc broadly depressed in 

 the middle, the depression with a sharply-defined arcuate median carina and a faint curved ridge on 

 each side. Elytra oblong-ovate, slightly wider than the prothorax, produced at the apex ; nodose and 

 irregularly seriato-foveate, the third interstice with an oblong prominence at the base, the elevations 

 with scattered smooth granules, the humeri subangular. Beneath sparsely foveato-punctate, the ventral 









segments 3 and 4 very short, 1 and 2 connate. Femora unarmed. 

 Length 8f-3£, breadth lf-lf millim.

specimens. Less elongate than A. truquii ; the head without a patch of white 

 the prothorax not so rugose, and with a short, conspicuous carina in the broad 

 depression; the elytra less compressed at the sides towards the apex, the 



vestitnre very sparse throughout, the humeri not prominent in front. This species has

wholly the facies of an Anchonus.

17. Acalles binodulus, s P . n. (Tab. IX. figg. 22, 22 a.)

a somewhat dense clothing of lighter and darker brown scales intermixed with scattered curled, clubbed, 

 decumbent set*, the tubercle on the third elytral interstice with a cluster of larger adpressed ochreous 

 scales. Head and rostrum densely punctate, the latter broad, rugose and carmate in the d, smoother 

 and feebly carinate in the ? . Prothorax short, rapidly narrowed from about the middle, constricted in
