48 KEVisiox or the amycterides, vi., 



anterior purtion lonning a slight ridge as in A. nanus, the central consisting of a 

 tonfuseil group of small, gi-anuliform tubercles, the posterior' of a single tubercle 

 backwardly directed, followed by a single tubercle posterior to constriction; 

 lateral tubercles similar. Elytra (8 x 4.5 mm.) .similar to A. »anu)<, apex 

 rounded, with a small, narrow, moderately deep emargination ; all the tubercles 

 smaller than the corresponding ones in A. nanus, first row with only 3 tubercles, 

 corresponding to the three apical ones, and noticeably smaller and less elevated; 

 second row with 4; third wth 2. Under surface similar, but with longer setae. 

 InteiTuediate tibiae with small, but evident subapical emargination. Dimensions: 

 6. 12 X 4.5 mm.

I have only a single male before me; this was received some years ago from 

 Mr. H. J. Carter, in whose collection is another specimen. Though closely allied 

 to A. squamosus Macl- and .4. Planus, the present species may be distingiushed 

 from both by the subapical emargination of the intermediate tibiae.

c?. Rather small, comparatively narrow. Black; moderately densely clothed 

 with Inown depressed pubescence, feebly maculate with gi'ey on elytra. 



Head concave in front, witli strongly raised intercristal ndge; supraorbital 

 crests consisting of two closely conjoined portions, arising from a moderately 

 narrow base, the anterior branch only separate at extreme apex which is directed 

 upwards and torwaixls, the anterior margin not strongly convex, the posterior 

 branch longer, pointed almost directly upwards. Rostrum rather deeply concave, 

 the lateral margins strongly angulate in front of middle; internal ridges promin- 

 ent, at first oblique, then parallel to base; basal foveae small, but distinct, closed. 

 Antennae of moderate length, the first two joints of funicle approximately eciual, 

 club moderately long, stout, not pedunculate. Prothorax moderately wide, median 

 area deeply impressed along median line, with a few, fine, scattered granules, 

 similar gianules present on sul)lateral areas; submedian tubercles erect, obtuse, 

 modei-ately large, but varying in size, not set in single series, the anterior tubercles 

 somewhat elongate and slightly cristaform, the central ones exsertcd, the prebii-sal 

 long, projecting directly backwards over the basal constriction; lateral tubercles 

 subtriangular, the median the largest, with a small conjoined anterior tubercle, 

 the posterior somewhat smaller than median. Elytra with fairly evident punctures 

 and rows of small somewhat indefinite granules; fli-st row of tubercles about 10 

 in number, the basal ones small, scarcely larger than granules and often indis- 

 tinct, the others becoming larger, but only the last 2 distinct, tlic apical decidedly 

 the largest and acutely conical; second row with 6—7, all distinct, though small 

 and rounded near base, the last 3 stronger and acutely conical; luuneral tubercle 

 small, noduliform; third row with 5 rather small tubercles, obtuse, hardly conical. 

 Ventral segments clothed rather sparsely with moderately long light setae, denser 

 at sides, arising from indistinct punctures; apical scgnnent gently convex antero- 

 posteriorly, with posterior face flattened and nitid. Leg's simjile.
