Itatlier shortly oval, more convex ty^^xx several of its con- 

 jyeiicrs, sliiniiij>-, castaiieous, almost unicolorous above and 

 beneath, but with tlie front marivin of the thorax paler and a 

 dark mark on its disc where tlie head shows through the 

 chitin, and with indistinct dark areas along the sides of the 

 elytra and near the front part of the suture, the latter forming 

 a median dark mark common to the two elytra ; legs and 

 antennre castaiieou^, the latter with the clubs not darker ; 

 body above and beneath covered with fine pale yellowish 

 ])ubescence. Thorax with base almost straiglit, only very 

 slightly sinuate on either side of the scutelium, with surface 

 finelv punctured, the punctures about twice their own diameter 

 apart. SculeUum finely punctured. Elytra about as long as 

 their combined breadth, with sutural stria indistinct (not indi- 

 cated in fig. 10 and in some positions hardly visible) and 

 obsolete in the anterior -|, more strongly punctured than the 

 thorax, punctures about twice their own diameter apart; 

 retlexion of lateral margins very slight, scarcely noticeable 

 from above. Wings apparently ample, but not dissected out. 

 Ventral surface closely punctured, except the middle of the 

 metasternura, which is almost impuiictate. 



It is not easy to describe the difFereJices separating this 

 form from others. It is not identical with any species 1 have 

 seen. Tlie following four are selected from Matthews's 

 collection for comparison, as they seem nearest to it. A. teslu- 

 dinalisy VVoll. (Madeira), is larger, less convex, more parallel- 

 sided, with the dark areas at the sides and suture of the 

 elytra contrasting much more strongly with the paler areas 

 between, and the elytral punctures very much closer. 

 A. croceus, Matth. (Siam), is uarrov^^er, much less convex, 

 more parallel-sided, and much paler and yellower; in punctua- 

 tion it is not unlike A. insnlce-hmgce. Tlie same remarks 

 ap])ly very nearly to A. seuegaleusis, Matth. A. westwoodi, 

 Matth. ((!eyloii), is larger, proportionately longer, less convex, 

 and generally lighter in colour, though with the daiker areas 

 on the elyira much the same as those of A. ■insuhe-longce ; its 

 antennse are much lighter coloured, being bright yellow; in 

 ]tunctuation it is not far removed from A. insulce-longce. 

 The latter differs from all these four species in its shorter, 

 more convex, less parallel-sided form, as well as in the other 

 ways mentioned in each separate case. 



Keitter (1908, ]). 61) has described a species — A. centii- 

 maculutus, from East Africa — wiiich seems to resemble 

 A. insulce-Iovgoe in many respects ; but without seeing a 

 specimen it is hard to say exactly how the two forms are 

 related. A. centrimaculatus is described as " breviter ovalis,"
