lobes prominent ; median line rather deeply impressed in the 

 middle ; median area of disc moderately broad, with a few- 

 scattered granules ; sublateral areas with a few fine granules ; 

 median ^oup of tubercles small, a pair moderately large, 

 anterior to subapical constriction, a group of four small ones 

 about middle, and a larger one nearer the middle line over- 

 looking the basal impression, one on either side of middle line, 

 at extreme base ; lateral tubercles triangular, flattened above, 

 outwardly directed, two anterior to middle, the second the 

 larger, one posterior to middle, about size of anterior tubercle, 

 also a small tubercle present anterior to subapical impression. 

 Elytra (13 x 7 mm.) rounded behind shoulders, thence sub- 

 parallel to before apex ; base truncate ; disc with rows of small 

 punctures, the intrastrial granules moderately prominent ; with 

 three rows of tubercles ; first row with about fourteen tubercles, 

 extending from base to edge of declivity, basal tubercles' very 

 small, becoming progressively larger, the last three spiniform, 

 the apical tubercle the largest ; second row with nine to eleven 

 similar tubercles, not quite reaching base, lower tubercles 

 somewhat outwardly directed, reaching a slightly lower level 

 than the first row ; third row with a strong outwardly directed 

 humeral tubercle, a subbasal tubercle about the same size or 

 slightly larger, then four smaller ones to about middle ; sides 

 with intrastrial granules moderately evident, the interstices 

 non-granulate. Beneath almost flat over ventral segments, 

 excepting the first; metasternum glabrous, with scattered 

 squames, but without evident punctures ; ventral segments 

 with a coarse reticulum of large oval punctures, separated by 

 narrow septae, a white squame present as a rule in each punc- 

 ture. Intermediate tibiae with a strong subapical emargina- 

 tion or notch. 



9 . Rather larger, more ovate than the male. Head 

 and prothorax similar. Elytra (14x9 mm.) more widened 

 posteriorly, not parallel-sided; tubercles smaller, thirteen in 

 first row and twelve in second (in the type), third row with 

 two strong basal tubercles as in the male, followed by a row of 

 eight, gradually becoming smaller, the first four or five dis- 

 tinctly tuberculiform. Beneath convex, with white squames, 

 but without evident punctures. Intermediate tibiae hardly 

 emarginate. Dim. — Male, 21 x 7 mm. ; female, 22 x 9 mm.

Closely allied to A. transitus, Macl., but larger and rela- 

 tively narrower, with much more numerous and considerably 

 smaller elytral tubercles. The median prothoracic tubercles 

 are more distinct than in A. transitus, though considerably 

 smaller and differently arranged than in A . amycteroides. The
