blance to DryophiJionis, from which it differs in not having 

 the prosternum in one plane, in its hood-Hke pronotnm, small 

 antennal club, short scape, short metasternum, and, above all, 

 in its deep prosternal furrow and strongly sinuate g'ular margin, 

 characters which I have not observed elsewhere in the 

 Cossoninae. 



Glyphostethus cancellatus sp. n. 



Male. Color dull black, the foveae filled with light brown incrustation 

 (possibly adventitious) ; the antennae and legs red-ljrown. 



Head finely rugulose all over, and with a faint transverse depression 

 across the forehead. Jiostrum narrowed from the base to the middle 

 and then gradually dilated to the apex; the uj)per surface distinctly 

 rugulose, without furrows or carinae. Prothorax as long as broad, very 

 convex with the sides gently rounded in the basal two-thirds, strongly 

 and very broadly constricted at the apex, the whole apical area beiug 

 depressed much below the level of the posterior portion; the basal margin 

 truncate and depressed, the apical strongly and broadly rounded; the 

 whole surface covered evenly with large reticulate foveae. Eh/fra parallel- 

 sided from the shoulders to beyond the middle, sharply constricted before 

 the apices, which are jointly and broadly rounded; the basal margin 

 trurfcate in the middle as fai' as interval 4, and shallowly bisinuate 

 between that and the shoulder; the broad shallow striae with reg.ular 

 rows of large reticulate foveae, the septa in the rows being as broad as 

 the intervals between the rows; the intervals finely rugulose; a shallow 

 impression behind the scutellum and a much deeper one on each side 

 near the apex. Length, 3.25 mm.; breadth, 1.4 mm.
