Rather slioitly oval, more convex tlian 5>everal o£ its con- 

 veners, shinino-, castaneous, almost unicolorous above and 

 beneath, but with tlie front margin o£ the thorax paler and a 

 dark mark on its disc where tlie head shows tlirough tlie 

 chitin, and with indistinct daidi 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 

 antennae castaneous, the latter with the clubs not darker ; 

 body above and beneath covered with fine pale yellowish 

 pubescence. Thorax with base almost straight, only very 

 slightly sinuate on either side of the scutellum, with surface 

 finely punctured, the punctures about twice their own diameter 

 apart. Scutellum finely ])unctured. Elytra about as long as 

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

 cated in tig. 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; 

 reflexion 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 

 nietasternum, which is almost impunctate. 



It is not easy to describe the differences separating this 

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

 seen. The following four are selected from Matthews's 

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

 dinnlis, Woll. (Madeira), is larger, less convex, more parallel- 

 sidod, 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 narrower, much less convex, 

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

 tion it is not unlike A. insuke-loticfce. The same remarks 

 ajiply very nearly to A. senegalensis, Matth. A. westwoodi, 

 Matth. (Cleylon), is larger, proportionately longer, less convex, 

 and generally lighter in colour, though with the darker areas 

 on the elytra much the same as those of A. lusulce-longof ; its 

 antenuEe are much lighter coloured, being bright yellow; in 

 punctuation it is not far removed from A. insulce-longce. 

 Tlie latter differs from all tliese four species in its shorter, 

 more convex, less parallel-bided foriii, as well as in the other 

 ways mentioned in each separate case. 



Heitter (1908, p. 61) has described a species — A. centri- 

 maculatus, from East Africa — which seems to resemble 

 A. insulcE-lovgce in many respects ; but without seeing a 

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

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