many scattering spots brown from denudation; apices conjointly 

 emarginate. Length 5 mm. Florida (Punta Gorda). 



suturalis Ham. 



Form more or less slender, but with the head behind the antennae always 

 as long as the prothorax and generally longer 4 



4 Elytra not evidently variegated, the close-set rows of punctures 

 uniform and very distinct throughout; head and prothorax very 

 densely cinereo-pubescent and obsoletely trilineate with paler tint, 

 the antennae (cf ) slender, not as long as the body, with numerous 

 very long flying hairs beneath, the scape two-fifths longer than the 

 head and clothed not very densely with extremely short coarse 

 hairs; prothorax equal in width to the head and slightly shorter, 

 evenly cylindric, two-fifths longer than wide; elytra at base as wide 

 as the prothorax, behind the middle nearly one-half wider, very 

 evenly convex, without trace of ridges except laterally toward base, 

 the punctures strong, very close in the even series, the pubescence 

 of the intervals not very dense, very short, fusco-cinereous and but 

 vaguely variegated by slight interruptions; abdomen with the short 

 hairs unusually sparse, not concealing the rather strong sparse 

 punctures; male with the fifth ventral short and transverse, broadly 

 sinuato-truncate, the sides of the elytra posteriorly evenly arcuate 

 to the acute apices, which are separated by a very small angular 

 emargination. Length (cf) 6.0 mm.; width 0.75 mm. Florida 

 (Lake Ashby), Schwarz suffusa Newm. 



Elytra variegated, with less distinct series of punctures and denser 

 vestiture 5 



5 Antennae with numerous very long flying hairs beneath; vertex before 

 the eyes nearly as long as wide, with feebly converging sides; body 

 moderately slender, evenly convex, obscure testaceous, the anterior 

 parts clothed with a very dense cinereous crust; antennal scape 

 extending to the middle of the prothorax, which is cylindric, two- 

 fifths longer than wide, with a short central groove, the flanks with 

 a whiter vitta and an impression near the apical and basal margins; 

 scutellum white, equilatero-triangular; elytra at two-thirds from the 

 base fully two-fifths wider than at the latter, the sides rounding 

 broadly to the external apical angles, which are rather acute, the 

 apices thence anteriorly and subrectilinearly oblique to the suture; 

 surface with uneven geminate series of rather coarse and close-set 

 punctures, which are partially visible through the dense pale brown 

 vestiture, which is in great part sparse near the suture and, at about 

 inner third, in the form of a whiter and irregularly much interrupted 

 vitta; apices feebly concave. Length (cf ) 9-6 mm.; width 1.25 mm. 

 Texas texana Csy. 



Antennae with but few and much shorter flying hairs, the vertex before 

 the eyes parallel and fully as long as wide 6 



6 Form moderately slender, convex and piceo-rufous, the moderately 

 thick crust of pale brown vestiture on the anterior parts when re- 

 moved revealing deep punctures, close-set on the head and less 

 coarse and sparser on the prothorax; antennae thicker than usual, 

 subglabrous, not quite as long as the body (cf), the scape densely
