tooth distinctly nearer base than apex, hind tibiae with two 

 rows of granules, of which one row is larger than the other, 

 but abruptly terminated ; basal joint of hind tarsi slightly 

 longer than second; claws without quills. Length, 10 mm.

The hind tibiae are certainly not normal, but the median 

 projection is not in the nature of a transverse carina (as on 

 tibialis and in the description of capitalis), but is due to the 

 abrupt termination of a longitudinal row of granules or 

 denticulations, somewhat as on rugosipes (which Blackburn 

 associated in his table with tibialis). It seems desirable 

 therefore that this species should be associated with those 

 mentioned, but from which (as from all others known to me) 

 it may be distinguished by the head, and especially by the 

 dentiform elevation (very distinct from the sides) on the front 

 of the clypeus. The head at the base is not evenly convex, 

 but there is a conspicuous flat-topped elevation abruptly 

 terminated at each eye ; from the sides the mentum appears 

 to slope upwards to a central point; from in front it appears 

 like a slightly truncated triangle, with the front face gently 

 concave. 



Maechidius squamipennis, n. sp. 

 PL xxxvii., fig. 91. 



Blackish ; legs obscurely paler, antennae castaneo-flavous. 

 Upper-surface with short, stiff, depressed, pale setae, but in 

 addition sides of prothorax and the elytra with large, elliptic, 

 depressed scales; under-surface with clothing varying from 

 stiff setae to short stout scales. 



Head rather lightly convex, densely granulate-punctate; 

 clypeus widely and very feebly notched in front, each side 

 with a moderately distinct notch near apex, and a very 

 feeble one towards the base. Prothorax moderately convex, 

 sides strongly rounded and strongly but obtusely serrated, 

 base bisinuate ; with large, round punctures, becoming smaller 

 and more crowded on sides. Elytra with geminate rows of 

 shallow, suboblong punctures, each with a small basal 

 granule; interstices feebly elevated. Front tibiae strongly 

 tridentate, third tooth almost in the exact middle; claws 

 without basal quills. Length, 8 mm.

A subopaque species. As the hind legs of the type are 

 missing it is impossible to place it in Blackburn's table 

 beyond A, B ; but the clothing of the upper-surface renders it 

 abundantly distinct from all previously described species; on 

 the pronotum the scales are confined to the sides, but on each
