prothorax ; horridula is therefore a valid species. There are a number 

 of other form?, notably three from Iowa and Nebraska, in my collection, 

 which seem to represent species different from /"ra.TzVz/ and helvola ; they 

 may be briefly outlined as follows : 



T. ocularis n. sp. — Form somewhat as in horridula but much smaller 

 and not so stout, testaceous in colour throughout, the elytra paler basally 

 but not definitely clouded or banded, the vestiture ochreous, elongate- 

 squamiform, the intervals with single series of longer suberect squamules ; 

 beak ( ,$ ) short and thick, the eyes, as in horridula, very large, convex 

 and coarsely faceted ; prothorax only three-fifths as wide as the elytra, 

 one-half wider than long, arcuately narrowed anteriorly ; sciitellum longer 

 than wide, acute ; elytra two-fifths longer than wide, obtusely rounded 

 behind, the humeri widely exposed, the striae shallow, moderately coarsely 

 punctate ; legs with long sparse hairs within, the anterior tibiae broadly 

 sinuate within in about apical half; fifth ventral not so large as in 

 horridula and not impressed ; pygidium rather large, semicircular. 

 Length, $ , 3.2 mm.; width, 1.4 mm. Nebraska. 



Readily distinguishable from horridula by the vestiture of the legs 

 and the sexual characters, the fifth ventral in that species being very large 

 and feebly impressed medially. 



T. punctata n. sp. — Body somewhat similar in form to ocularis but 

 still smaller and more slender, pale ochreo-testaceous throughout, the 

 vestiture similar but sparser ; beak ( 5 ) slender, arcuate, nearly as in 

 horridula, the eyes smaller than in the male and less convex ; prothorax 

 notably small, rather more than one-half wider than long, less parallel than 

 in ocularis, trapezoidal, with arcuate sides and having a fine entire 

 impunctate median line ; scutellum large, longer than wide, acute ; elytra 

 more parallel^ obtusely rounded behind, with well exposed humeri, the 

 strise more impressed and coarser, with very coarse, deep and close-set 

 Dunctures. Length, 9 . 2.5 mm ; width, 1.2 mm. Iowa. 



Distinguishable by its small size, slender form, small prothorax, very 

 coarse strial punctures and the fine entire impunctate pronotal line, the 

 latter being broader and only visible behind the middle in ocularis. 



T. brevis n. sp. — General form somewhat as in helvola but shorter 

 and relatively stouter, obscure testaceous throughout, with rather dense 

 short decumbent vestiture of ochreous scale-like hairs, with only a
