antennae ; having tlie tliorax more evenly rounded outwards at the sides, 

 a little more strongly punctured, with the anterior angles even more 

 rounded off, the posterior angles rather more evident, and the base 

 with scarcely a trace of the sinuation so conspicuous just before the 

 hinder angles in calcarata ; the elytra not quite so acuminate behind, 

 and with the punctures of the strise larger ; and the structure of the 

 posterior legs in the male dissimilar. These have the femora on the 

 under side, nearer the base than the middle, suddenly and obliquely 

 contracted towards the base, the commencement of the contraction 

 forming a distinct and minutely denticulated angle ; their outer angle 

 is entirely rounded off, with no projection ; and the inner angle has a 

 rounded prominence, much as in duhia, ^ : their tibiae are very long 

 and thin, slightly incurved and very slightly widened just before 

 the apex. 



Its more elongate and less convex shape and linear anterior tibiae, 

 the small apical joint of its antennae, and the angular lower side of 

 the middle of the hind femora of its ^ , render any comparison with 

 A. duhia unnecessary. 



From A. scita, Er., it appears to differ in its more elongate shape, 

 the small apical joint of its antennte (Erichson emphasizes the club of 

 the antennae of his scita as having the three apical joints of equal 

 width), the elongate hind tibiae and not prominent outer under-angle 

 of the femora of its ^ , &c. 



From A. Trieplcii, to which it is somewhat closely allied in its 

 short antennae wdth small apical joint, and in the angularity of the ^ 

 posterior femur in the middle beneath, it differs at once in its average 

 smaller size, undilated anterior tibiae, longer, narrower and less convex 

 build, narrower head, and rather longer antennae, the scarcely perceptible 

 bisinuation of the base of its thorax, the sides of which are not so 

 strongly rounded outwards in the middle, or so contracted behind, 

 the rounding towards the apex of its elytra not commencing at the 

 shoulder, but at the j)osterior half of the side, the slight and single 

 curve towards the apex of the posterior tibiae of its ^ , &c. 



Judging from description, it appears to agree with A. geniculata, 

 Fairm., in being of a lighter colour than calcarata, and having the 3rd 

 joint of its antennae shorter in comparison, and the base of its thorax 

 less strongly bisiuuate ; but it has not the knees darkened, or a wide 

 flattened sharp tooth to the posterior femora and strongly incurved 

 posterior tibiae in the ^ ; and it is longer, less convex, more strongly 

 punctured, and with less obtuse posterior angles to the thorax.
