toothed, very densely and toward the base coarsely and rugosely 

 punctate; aedeagus similar to that of M. platylonchus in having a 

 broadly hollowed-out apex. 



Head covered with scales down to antennal sockets, beneath these 

 the punctures coarse and tending to be rugosely striate ; a median line 

 ending in a shallow depression between the eyes, the usual pair of 

 occipital ridges. Antennae reddish brown and of the usual propor- 

 tions. Prothorax wider than long, not very convex, with a basal 

 depression along margin, the three lateral teeth well developed, and 

 a tooth at apical and basal angles ; punctation dense, tending to be in 

 short lines, and becoming coarser and rugose toward the base. Elytra 

 with a short intrahumeral sulcus and slight transverse lateral depres- 

 sion below the sulcus ; striate punctures very close and coarse and in 

 basal part in the depression with transverse ridging ; surface lustrous 

 beneath the curved, not dense, grayish-white scales. Body beneath 

 shining, with fine pale pubescence, first abdominal segment coarsely 

 and densely punctate. Hind femora with a tiny tooth, anterior tibiae 

 toothed. Length 4.8 to 5.5 mm. ; width 2.2 to 2.5 mm. 



Type and paratypes. — Type male and one paratype, U. S. N. M. No. 

 59021, "in banana debris from Ecuador," April 13, 1947; one paratype 

 in Museum of Comparative Zoology. 



Type locality. — "Taken from banana debris from Ecuador" at New 

 Orleans, La. 



Other locality. — Peru: Piura. 



Remarks. — Although quite distinct from M. platylonchus., this 

 species belongs to the same group. It is about the same size, a little 

 darker in color, with grayish instead of yellow scales. It has the 

 same dense rugose punctation, the shape of the prothorax is similar, 

 and the aedeagus is strikingly like that of platylonchus in shape, both 

 when viewed from the side and in the broadly scooped-out tip, al- 

 though the tip is a little narrower. The pubescence is thicker and 

 paler in geminus. Two specimens from Piura, Peru, collected by 

 P. A. Berry in cotton buds, October 15, 1941, are apparently the same. 



MYOCHROUS ELACHIUS, new species 

 Plate 4, Figure 3 



From 4.5 to 5 mm. in length, oblong, shining bronze beneath the 

 closely appressed, mottled pale and dark brown scales; prothorax 

 3-toothed, a little wider than long, not very coarsely but densely 

 punctate ; aedeagus pale with a dark furrow running down the tip. 



Head covered with scales down to antennal bases, beneath the scales 

 the punctation not dense or rugose, the usual occipital ridge on each 

 side, and in some specimens a faint median line. Antennae reddish 

 brown, of the usual proportions. Prothorax a little wider than long 

 with three lateral teeth and a tooth at basal and apical angles, mod- 

 erately convex with a depressed line along the basal margin ; puncta-
