Plate 30, Figure 15 



Male. — Reddish brown; 1.21 mm. long, 2.44 times as long as wide; 

 allied to hopkinsi but differing in several respects. 



Frons convex above, strongly, transversely flattened below, shining, 

 strongly, roughly punctured, with short, stout, scalelike hairs; epis- 

 tomal margin with longer, slender hairs extending orad and partly 

 concealing mandibles. Eye broadly oval, inner margin entire, facets 

 small. Antenna (pi. 30, fig. 15) with scape longer than either club 

 or funicle, slightly club shaped with scanty fringe of long hairs, club 

 shorter than funicle, 1.25 times as long as wide, sutures indicated by 

 setal rows, first slightly bisinuate, second nearly transverse. 



Pronotum very slightly wider than long, subtriangular in shape, 

 widest near base, posterior outline weakly arcuate, posterior angles 

 rounded; sides convergently arcuate, weakly constricted anterior to 

 middle, narrowly rounded in front, subangulate medially, with several 

 small serrations; summit lighter in color, high, slightly behind center; 

 anterior area with subconcentric rows of small asperities and short, 

 stout setae not extending to middle at sides; posterior area sloping 

 toward base, feebly shining, reticulate, finely, indistinctly punctured 

 on disk and sides, appearing glabrous but with a few T very fine, in-
