Decilaus squamosus, Pasc; Mast. Cat. Sp. No. 5460. 



Clothed with large white scales each set in a puncture and 

 causing both upper and under surfaces to appear speckled. Scales 

 denser on legs and sparser on apical segments of abdomen than 

 elsewhere. Pectoi'al canal with white scales. 



Head, especially on vertex, with considerably smaller punctures 

 than on rostrum. Rostrum wide, feebly incurved to middle; with 

 large and slightly irregular punctures. Scape the length of 

 funicle, inserted nearer apex than base of rostrum and passing 

 apex. Prothorax slightly transverse, apex not half the width of 

 base ; with moderate-sized regular round punctures almost con- 

 cealed by scales. Elytra oblong-cordate, slightly wider than 

 prothorax and not twice as long, widest slightly behind base ; 

 striate-punctate, punctures large, round, in places approximate 

 but usually not ; interstices equal in width or wider than 

 punctures, towards apex and sides feebly granulate, with feeble 

 punctures only visible on abraded specimens. Two basal seg- 

 ments of abdomen subequal, with large round and comparatively 

 sparse punctures, apical segment densely punctate, intermediates 

 narrowly raised anteriorly, depressed and with large scales pos- 

 teriorly. Length 5, rostrum 1; width 2 mm.

The prothoracic punctures are deep but almost concealed by 

 the large scales arising from each and which give the surface a 

 speckled appearance ; the elytral granules are little more than 

 feeble and irregular elevations of the interstices, but appear to be 

 true granules until the scales are abraded. I have three speci- 

 mens (taken by Mr. Masters) under examination. 



Decilaus perditus, Pasc; Mast. Cat. Sp. No. 5476. 



(Acalles 2Jerditus, Pasc.) 



Clothed with modei'ately large scales, varying in colour from 

 white to brown; on the prothorax the scales are usually entirely 

 brown and each one is set in a puncture; on the elytra there are
