Kansas. The specimen described is probably a female, the fifth 

 Tentral being broadly rounded behind. 



2. M. facetus u. sp. — Moderately stout and convex, rather shining, pale 

 testaceous in color, the elytra ^vith a sutural area not attaining the apex and 

 sinuately narrowed before the middle of black; under surface of the hind 

 body black, the mesosternum and fifth ventral segment pale; legs pale, the 

 hind thighs infuscate except toward tip; pubescence short, not very dense, 

 pale, rather fine and sxibdecumljent, intermixed on the elytra with numerous 

 short and more erect hairs of the same color; marginal fringe almost obsolete. 

 Head missing in the type. Prothorax three-fifths wider than long, the sides 

 subparallel, rather acutely prominent at basal two-fifths, thence feebly con- 

 vergent and broadly sinuate to the apical angles which are rounded from 

 above, and slightly convergent and nearly straight for a short distance to the 

 basal angles, these being obtuse but evident ; base and apex broadly and al- 

 most equally arcuate, the former verj" slightly the wider ; disk rather coarsely 

 but feebly, sparsely and somewhat inconspicuously punctate, the marginal 

 acute edge fine, raj)idly descending far down the fianks from the base to apical 

 third, then more rapidly and subtransversely ascending in a broad arc. Elytra 

 two-fifths longer than wide, only just visibh' wider behind and scarcely two- 

 thirds wider than the prothorax, the sides subparallel and feebly arcuate ; apex 

 obtuse, broadly truncate toward the middle, the sutural angles right; humeri 

 tumid but not very widely exposed at base ; disk rather coarsely but feebly, 

 sparsely and inconspicuously punctate toward base, the sculpture ])ecoming 

 very fine toward apex. Under surface rather thinly clothed with very short, 

 fine and subcinereous pubescence, the legs slender. Length ( exclusive of the 

 head) 1.9 mm. ; width 0.95 mm. 



Arizona ? 



The single specimen, which I found among some discarded ma- 

 terial some years ago, is without any indication of locality, but 

 was in all probabilit}' taken by Mr. Morrison ; it is a male, the 

 fifth ventral being short and broadl}' truncate, with a small feeble 

 sinuation at the middle of the truncature. I do not think that it 

 could by any possibilitj' be the male of the preceding species, 

 which is known to me only by the female. 



DOLICHOSOMA Steph. 



The American type of this genus has no vestige of elytral epi- 

 pleur8e,the lower edge being acute and without a submarginal line 

 even toward base. This peculiarity necessitates its isolation 

 from all other generic groups of the tribe. 



The tarsal claws are stout and strongly developed, the inner 

 having a large corneous internal dilatation in basal half, which is
