the short, somewhat curved, brown and white scales, thorax 3-toothed, 

 a little broader than long, densely covered by round deep punctures ; 

 aedeagus with an unusually long, slender point at the tip. 



Head covered with browji and white closely appressed scales down 

 to the antennal sockets, lower front with finer, sparser pubescence; 

 densely punctured beneath and rugosely punctured over the occiput, 

 front with a median furrow, the usual occipital ridge on either side. 

 Antennae reddish brown of the usual proportions. Prothorax large, 

 about one-half as long as the elytra, distinctly wider than long, mod- 

 erately convex, depressed along the base, especially over the scutellum ; 

 punctures round, deep and dense, covered by short curved scales ; the 

 three lateral teeth well developed and the usual tooth at the basal and 

 anterior angles. Elytra broad, with a slight basal callosity and a 

 little tendency toward costation in basal half ; striate punctation about 

 scutellum deep and depressed, elsewhere punctures not very coarse 

 and well spaced ; the brown and white scales short, dense, and some- 

 what curved, not entirely concealing the sculpture. Body beneath 

 shining piceous with a reddish brown tip to abdomen and dark reddish 

 brown to piceous legs; first abdominal segment somewhat coarsely 

 and often moderately densely punctate ; scales fine and sparse. Hind 

 femora toothed, anterior tibiae with the usual tooth on the inner side. 

 Length 5.8 to 6.5 mm. ; width 2.8 to 3.2 mm.

Remarks. — Both M. hohemani Lefevre and M. armatus Baly were 

 described from Brazil a few years apart. I have examined a cotype of 

 M. ai^iatus and the type of M. hohemani {denticollis Boheman) and 

 find them nearly identical in appearance. The large size, the very 

 densely punctate thorax, which is approximately one-third the length 

 of the beetle, and the exceptionally long attentuated tip to the aedeagus 

 characterize this species. It appears to be well distributed over the 

 southern part of South America.
