differs from both Oxypoda and Dasyglossa in that the raeso- 

 sternal process is narrowly truncate at tip. The tarsi are 

 5-5-5-jointed, the general form as in Oxypoda but with 

 much coarser and sparser sculpture, especially of the abdo- 

 men. The hypomera are visible from the sides, the tarsi 

 rather short, the basal joint of the posterior about as long as 

 the next two combined. Additional characters may be de- 

 rived from the following diagnosis of the only species known 

 to me thus far: — 



Body stout, convex, opaque and micro-reticulate, the abdomen more shin- 

 ing and with feebly imbricate sculpture i pale ochreous-yellow in color, 

 the abdomen with a very faint cloud involving the fourth tergite; legs 

 and antennae pale; punctures moderately fine and and rather close-set, 

 less close on the abdomen; pubescence pale, rather long and shaggy; 

 head orbicular, rapidly narrowed behind the eyes to the base, the eyes 

 large, somewhat prominent; antennae about as long as the head and 

 prothorax, rather thick and incrassate distally, the subapical joints trans- 

 verse, the eleventh somewhat longer than the two preceding combined, 

 the second slightly shorter than the third, both shorter than the first; 

 prothorax three- fourths wider than the head, more than one- hall wider 

 than long, the sides distinctly converging from base to apex and some- 

 what strongly, evenly arcuate, the basal angles obtusely rounded, the 

 surface feebly flattened along the middle in basal half; elytra equal in 

 width to the prothorax and only very slightly longer; abdomen at base 

 very nearly as wide as the elytra, almost evenly but just visibly tapering 

 thence to the tip, the border rather thick, the first two tergites dis- 

 tinctly, the third very obsoletely impressed at base. Length 1.9 mm. 

 width 0.75 mm. New York (near the city) ochracea n. up.

There is but one specimen before me and this exhibits nO' 

 sexual marks. 



Baryodma Thorns. 



Rather slender, parallel, convex, polished, deep black, each elytron with a- 

 large rufous spot in apical three- fifths near the suture; legs piceous- 

 black, the antennae black; head longer than wiiie, with a few fine 

 scattered punctures; antennae moderately incrassate distally, scarcely 

 as long as the head and prothorax, the subapical joints transverse, the 

 second rather longer than the third; prothorax evidently less than twice 

 as wide as the head, subparallel, about one-half wider than long, the 

 apex broad and but little narrower than the base, the sides feebly, 

 evenly arcuate, the surface with a scarcely at all impressed double 

 series of irregularly disposed punctures and some fine punctures 

 sparsely scattered toward the sides; elytra transverse, the sides as long 

 as the sid«s of the prothorax, the suture three-fourths as long as the
