densely covered by round deep punctures becoming coarser toward 

 base; elytra lacking any basal callosity, striate punctures near base 

 unusually coarse and transversely ridged ; scales exceptionally coarse, 

 curved, and mottled brown and grayish. 



Head covered by short brown and gray scales down to antennal 

 sockets, surface below obsoletely punctate, an mipressed median line 

 down front, the usual occipital ridge on each side. Antennae of the 

 usual proportions, reddish brown. Prothorax a little wider than long, 

 almost as wide as elytra and one-third the length of the beetle, 3- 

 toothed, moderately convex, with a depression along basal margin, 

 densely and moderately coarsely but not confluently punctate, the 

 punctures round and deep and a little coarser toward base. Elytra 

 without any basal callosities, a short intrahumeral sulcus and a slight 

 depression below the humerus ; punctures very coarse and transversely 

 ridged in basal portion, and hidden by the mottled brown and gray 

 curved scales that are unusually coarse. Body beneath shining bronze 

 under the fine white scales, first abdominal segment coarsely punctate. 

 Hind femora bluntly toothed; anterior tibiae with the usual inner 

 tooth. Length 5.4 to 6.5 mm. ; width 2.6 to 2.9 mm. 



Type and paratypes. — Type male and one paratype in British Mu- 

 seum, collected in November 1903, by G. E. Bryant ; two paratypes in 

 Museum of Comparative Zoology; one paratype, U.S.N.M. No. 59135. 



Type locality. — Trinidad, British West Indies. 



Other localities. — Trinidad: Capara Valley, Port of Spain, Janu- 

 ary 1897 (Dr. Kendall) ; 7 miles north of Moruga village (June 13, 

 1925, P. A. Andrews) ; Montserrat (June 29, A. Busck) ; Palo Seco

Remarks. — The large densely punctate thorax of this species re-
