36 REVISION OP THE AMYCTEinUKS, VI., 



Head strongly concave in front, supraocular crests large, broad at base, with 

 the two rami almost completely fused, the anterior ramus not projecting forwai-d, 

 rounded above, separated from posterior by a slight indentation on free margin, 

 the posterior prolonged as a strong conical process; intercristal ridge strongly 

 raised, running into base of anterior portion of crests. Rostrum widely and 

 moderately deeidy concave in front, with lateral margins strongly angulate in 

 middle; internal ridges widely divergent anteriorly, basal foveae small but 

 evident. Antennae with second joint of funicle longer than fii-st; club elon- 

 gate-obovate. Prothoras (4.5 x 5 mm.) with feeble ocular lobes; median area 

 rather broad in middle, median tubercles consisting anteriorly of a pair on each 

 side, conjoined to form shoi-t parallel ridges, in centre of a gi-oup of rounded, 

 somewhat depressed, confused tubercles, and posteriorly of a large, strong, back- 

 wardly jirojecting tubercle on each side, strongly convergent and obliquely set, 

 their inner surfaces looking upwards and inwards; lateral margins witli a pair of 

 conjoined tubercles in front of middle, triang-ular, flattened above, and with a 

 single smaller tubercle posterior to middle. Elytra (11 X 6.5 mm.) elongate, 

 only moderately widened posteriorly; punctures obscure, and granules small and 

 indefinite; sutural interstice with a slightly elevated ridge on each side of Ijase; 

 with tliree rows of moderately strong spinose tubercles, first row with 7 tubercles, 

 the basal ones smaller and not conical, the last "2 — 3 conical and ending at edge 

 of declivity; second row with 7, projecting outwards and upwards, ending at 

 level of declivity; third row with humeral tubercle large, but smaller than follow- 

 ing one, and 5 other spinose tubercles, extending to middle of elytron. Lateral 

 interstices somewhat obsoletely granulate. Under surface rather closely set with 

 moderately long black setae arising from small punctures, the- apical segment more 

 asperate-punctate. Leg's with intermediate tibiae strongly emarginate above apex; 

 posterior tarsi with first joint comparatively short and stout, as in .-I. marshami. 



?. Larger, more dilatate than male, the elytra broader, more ovate in out- 

 line; under surface more strongly convex; intermediate tibiae not notched. 

 Dimensions: c?. 16 X 6.5 mm.; 9. 19 X 8.5 mm. 



//n?).— N.S. Wales: Inverell. 



The shape of the posterior pair of thoracic tubercles should render this 

 species easy of I'ecognition. these tubercles are somewhat larger, broader iind 

 more flattened in the female. The combination of comparatively short posterior 

 tarsi with the notched intermediate tibiae should also distinguish it from its 

 known congeners. 



I have at various times seen a number of specimens of this species, all from 

 the New Englanil Tablehiiid in tlie vicinity of Inverell.

c?. In general apjiearancc resembling A. mnrshami. but venter differently 

 sculptured. Hlack, dotliing scanty. 



Head concave in front, intercristal ridge low; supraorbital crests larger than 

 in .1. marsliami, the anterior ramus strongly convex anteriorly, witli apex obtuse, 

 the posterior ramus somewhat longer, directed slightly backwanls. Kostrum 

 similar to A. marshami, but with the external margins more strongly angulate. 

 Antennae with first and second joints of funicle subequal; club short, hardly 

 pedunculate. Prothorax with two anterior tubercles of subinedian ;rroup separ-
