J. monosperma at Nogal, N. Mex. 
PHLOEOSINUS CHAMBERLINI, new species 
Male.—Black, shining, with elytra ferruginous to piceous near 
base, reddish brown on declivity; 2.05 to 2.51 mm. long, holotype

Frons very wide between eyes, frontal rectangle about 0.66 as long 
as wide; epistomal lobe short; surface black, shining, finely and 
densely granulate-punctate at sides, with deep, slightly coarser punc- 
tures, not granulate above; central area rather deeply and broadly 
concave, central two-fifths of concavity brightly shining, impunctate,
