ridges little evident, couvergent towards biise. Antennae slender, tirst two joints 

 of funic'le snbequal, dub with moderately long- peduncle. Eyes rounded. Pro- 

 thorax with submedian row of tubercles in single series, the tul)ercles long, slender, 

 erect, like a palisade, the anterior tubercle projecting overhead and upturned at 

 apex, the second, third and fourth with a slight backward curve, the third the 

 largest, the fifth much smaller than the others, no tubercle posterior to basal con- 

 striction, the latter ill-defined ; lateral margins with a long, slender, curved spine 

 in middle, with a small, conjoined anterior one, and a short obtuse tubercle pos- 

 teriorly, its apex bent backwards. Eh-tra rather strongly rounded on sides, 

 strongly convex antero-posteriorly and from side to side, strongly declivous to 

 base of prothorax, and basal margin set with three, small, fonvard-pi-ojeeting 

 tubercles at the ends of the first, third and fifth interstices; the fli-st. second, 

 fourth and sixth interstice,s with rows of small but evident granules, much dis- 

 placed liy the tubercles on the intervening interstices; with three rows of strong 

 siiiniforui tubercles, the first with (i, all upright spines, the posterior ones very 

 long and curved; second witli 4 similar to those of first row, but larger and end- 

 ing on same level ; humeral tubercle placed at junction of fifth, sixth and 

 seventh interstices, in line with tubercles of second row, large and spiniform, 

 with two small gTanules anterior to it; third row with two outwardly-projecting 

 spines. AVniter fiat, sparsely and shallowly setigero-punctate. with whitish 

 squames at sides of segments. Legs simple. 



9. As in d', but more strongly rounded on sides; venter convex and more 

 evenly clothed witli white squames. Dinien,sio)/s: S. 10.. 5 ^ 5 mm-; 2. 9.5 '>^ 4.5 

 mm.

A second female differs in being larger, with proportionally longer elNira and 

 more numerous tubercles, — 7, 5, 5; the dimensions are 12 >< 6 mm. 



Though associated with A. hirittatux Bohem., it is not very closely allied to 

 that species; it is closest in appearance to A. kreffti Macl., but it is really a 

 species swi generis.

Small, elongate. Black; sparsely clothed with daik subpubescence. with a 

 narrow median creamy vitta, bifurcate on liead and extending almost to edge of 

 declivity; with creamy macules on elytra, on declivity between first and second 

 rows of tubercles and towards lateral margins; sides with a white vitta extending 

 along middle of prothorax and along lower margin of elytra. 



Head concave in front with two small granules above; intercristal ridge low; 

 supraorbital crests composed of two short stumjiy jirocesses separate practically 

 to base, the intercristal ridge running into the anterior one. Rostrum rather 

 deeply concave; external margins somewhat raised. ol)tusely angulate in front, 

 and sinking to base; internal ridges moderately long, distinct, convergent to base. 

 Eyes ovate. Antennae slender, first and second joints of the funicle subequal, 

 club short, not pedunculate. Prothorax with meilian area moderately deeply de- 

 pressed ; submedian tubercles small, erect, subconical, not in a straight line, tlie 

 central ones being more outwardly placed: lateral tubercles acute, subspini- 

 form, the median the longest, the anterior half as Ions' as median, conjoined.
