punctures. Pygidium with crowded punctures. Front tibiae 

 tridentate, the two first teeth large and acute, the third small, 

 acute, and subbasal ; basal joint of hind tarsi much shorter 

 than second. Length, 6-6'25 mm.

In size and structure close to olliffi, with which it would 

 be associated in Blackburn's table, but the elytra have much 

 longer clothing, and with scarcely a trace of metallic gloss; 

 debilis has the clypeus somewhat different, the metallic gloss 

 of elytra more conspicuous, and the clothing shorter ; the tips 

 of the elytra are obscurely reddish as in grisea, but the cloth- 

 ing of that species is much shorter and the clypeus is very 

 different. On the upper-surface there are fairly dense sub- 

 depressed hairs, each about the length of a claw, and mixed 

 with these (and very distinct from the sides) are longer erect 

 ones, fairly dense on the head to base of elytra, but disap- 

 pearing before the apex of the latter. From some directions 

 the prothorax appears to be covered with small granules, much 

 as in many small weevils (e.g., Essolithna, Polyphrades, etc.). 

 The semidouble rows of elytral punctures are very irregular, 

 and are in shallow longitudinal impressions, but these could 

 scarcely be regarded as striae ; on each elytron there are three 

 interstices that are conspicuously wider than the others, but 

 all have jagged edges due to punctures. The clothing some- 

 what obscures it, but the whole of the derm appears to be 

 very finely shagreened. 



Maechidius hackeri, n. sp. 



Castaneous, some marginal parts darker, club paler. 

 Moderately densely clothed with long, erect, golden or light- 

 brown hairs; parts of under-surface with rather sparse, sub- 

 depressed pubescence. 



Head with coarse and rather crowded punctures. Clypeus 

 deeply notched in front, each side conspicuously trilobed. 

 Antennae with the club three- jointed. Prothorax about 

 twice as wide as long, sides moderately rounded and finely 

 serrated, front angles produced and moderately acute, hind 

 ones obtuse and entire ; punctures as large as on head, but less 

 crowded. Elytra feebly dilated to beyond the middle, with 

 double rows of large punctures. Pygidium convex, with 

 asperate, setiferous granules. Front tibiae tridentate; each 

 claw with a conspicuous basal quill. Length, 8 mm.
