portion ; scales short, curved, brown and white (much rubbed) . Body 

 beneath with scanty fine pale hairs, first abdominal segment rather

Type—K male, U.S.N.M. No. 59031, collected in March by W. T. 

 Foster,

Plate 4, Figure 1 



About 6 mm. in length, elongate oblong, shining piceous beneath 

 the closely appressed gray scales, prothorax not very convex, with 

 three large lateral teeth, coarsely, densely, and rugosely punctate. 



Head covered by short, closely appressed scales down to antennal 

 sockets, with a fine median line, rugosely punctate beneath the scales ; 

 occiput concealed in the single specimen examined. Antennae and 

 mouthparts reddish brown; antennae extending below the humeri, 

 of the usual proportions. Prothorax not quite so long as wide, not 

 very convex, with a slight anterior depression and a basal depression 

 most marked over the scutellum ; sides with three well-developed teeth 

 in addition to the apical and basal teeth; surface coarsely, densely, 

 and rugosely punctate. Elytra without marked basal callosity, a 

 faint trace of transverse depression on the side below the intrahumeral 

 sulcus ; striate punctures coarse, dense, but not ridged, showing through 

 the short gray scales. Body beneath and legs not so deep in coloring 

 and only sparsely covered with finer scales, especially the abdomen; 

 first abdominal segment moderately coarsely punctate. Hind femora 

 indistinctly toothed; anterior tibiae with the usual inner tooth. 

 Length 6.3 mm. ; width 2.9 mm. 



Type. — ^A male. Museum of Comparative Zoology type No.. 28120, 

 collected by Dr. Bohls. 



Type locality. — San Salvador, Paraguay. 



Remarks. — This species is a typical Myochrous and similar to others 

 of the genus with few distinctive features to mark it. It is smaller 

 and more slender than M. armatus Baly and with a more rugosely 

 punctate prothorax. The aedeagus is similar to that of many of the 

 North American species, notably the West Indian species, but with 

 a slightly shorter tip.
