52 RFA'I.SION OP THK AMYCTERIDES, vi., 



anterior very short, projecting ahiiost direi-tly I'orwards, tbe posterior soiuewhut 

 longer and curved u))wards ; iutereristal ridge low in centre, running into base of 

 anterior ramus. Antennae with scape stout, the fuuicle with joints rather short, 

 the first and second subequal, tbe club rather briefly obovate. Prothorax (4 x 

 5 mm.) with a row of upstanding, moderately large, obtuse tubercles, in single 

 series, on each side of median area; lateral margins with a strong spiniform 

 tubercle anterior to middle, conjoined with a smaller tubercle anteriorly, and 

 with a much smaller tubercle, less than half as long, posterior to middle. Elj-fra 

 (9.5 >< 5 imn.) subparallel on sides, rather strongly convex transversely; derm 

 asperate, with punctures confused, often transverse, and rows of granules, rather 

 confusedly set; with three rows of small tubercles, the basal ones small, the others 

 becoming progressively larger and more acutely conical, also with two or three 

 tubercles on second interstice above declivity : fii-st row with 9 tubercles, the la-st 

 3 — 4 conical, ending on edge of decli\-ity; second with 7, extending fartlier pos- 

 teriorly, almost all conical, spiniform, though smaller anteriorly; third with a 

 strong, conical, humeral tubercle, outwardly projecting, and 4 others all conical, 

 becoming smaller posteriorly and continued as a row of obsolete granules. Sides 

 with rows of rather obscure granules on interstices. Under surface flattened, set 

 with long black setae. Intennediate tibiae witli a small, narrow, pre-apical 

 emarginatiou ; posterior tibiae witli an anteriorly projecting process at apex, con- 

 cave on under surface. Dimetwiinns : c?. 14 x 5 mm. 



Hab.—N. Queensland (F. P. Dodd) . 



I have seen but a single specimen of this species, and tliough not in good 

 condition I have described it, as it is evidently distinct from A. kreffti. its nearest 

 ally. From the latter it is distinguished by the smaller, less spinifonn supra- 

 orbital crests, and by the smaller elytral tubei'cles. 



I received my single specinu'n some years ago from llr. Dodd, of Kuranda. 

 and, though without locality label, believe it comes from the hinterland behind 

 Cairns, either from Mareeba or the Atherton-Herberton district.

c?. Small, ovate, strongly spinose. Black; densely clothed with small 

 squames, whitish or rich brown; head with two narrow while lines and sprinkled 

 with wiiite on the sides; prothorax with a whitish median vittii, more creamy in 

 centre, with sul)lateral vittae coppery-brown, sides with a whit<' vitta above and 

 sprinkled witli wliite below; elytra with median villa luoslly coppery-brown, 

 mixed with white anteriorly, the brown ending on declivity, then<'e sprinkled with 

 wliite, with wavy vitlae of c()p])ery-bi'<)wn between the rows ot tubercles, with 

 patches of white at the jjosterior ends of the vittae, sides witli a wavy ritta of 

 white along middle and a less distinct one along lower margin; sides of sternal 

 segments with dense white sciuames above, the rest of the under surface sprinkled 

 with white. 



Head concave in front, intercristal ridge low in centre; supraorbital crests 

 composed of two separate slender spines, the .anterior directed upwards and very 

 slightly forwards, the posterior almost directly upwards and longer than the 

 anterior, the intei-cristal ridge ninning into the base of the anterior ramus. 

 Ko.strum h.ardly excavate, the lateral margins hardly raised, not angulate; internal
