Head strongly convex and with large granules betwe: 

 eyes, with large punctures in front; clypeus deeply notches 

 in front, and with three strong teeth on each side, the basal 

 tooth more obtuse than the others. Prothorax rather strongly 

 and evenly convex, sides obtusely serrated, base rather 

 strongly bisinuate, the hind angles almost rectangular; with 

 numerous distinct granules, each marking the base of a 

 puncture. Elytra with close-set geminate rows of shallow, 

 suboblong punctures, with indistinct granules. Pygidium 

 with large shallow punctures, and without a median carina. 

 Front tibiae strongly tridentate, the third tooth distinctly 

 nearer base than apex ; basal joint of hind tarsi slightly longer 

 than second, claws slightly appendiculate at base, but without 

 quills. Length, 6|-7 mm.

The size of parvulus, but the head very different. In 

 Blackburn's table the species would be associated with major 

 and gibbicollis , but it is very much smaller, and the sides of 

 the clypeus and the mentum (this is conspicuously keeled 

 along the middle) are very different. The appearance as of 

 rows of beads on the elytra is very ill-defined on the species. 



Maechidius conspictjus, n. sp. 

 PI. xxxvii., fig. 90. 



Reddish-brown and shining; antennae flavous. Upper- 

 surface with short, stiff, depressed, whitish setae, becoming 

 conspicuously longer on under-surface, and still longer on 

 legs. 



Head conspicuously elevated between the eyes, and with 

 rather large punctures ; clypeus widely notched in front, the 

 middle of the notch with a distinct subtriangular elevation, 

 each side with three lobes, the front one subdentiform, the 

 second more obtuse, and the third still more obtuse. 

 Prothorax moderately convex, with a vague longitudinal 

 impression and remnants of a still more vague transverse one, 

 sides rather strongly serrated, and silbangulate in middle, 

 base strongly bisinuate, the hind angles slightly obtuse ; 

 with moderately large punctures, not very crowded about 

 middle. Elytra with narrow striae, the interstices wide and 

 with punctures cutting into each so as to give their margins 

 a crenulated appearance, towards the sides each interstice 

 becomes almost like a continuous series of small zigzags; 

 without distinct granules. Pygidium with moderately large 

 punctures, becoming crowded about apex, with a shallow 

 median line. Front tibiae strongly tridentate, the third
