Elongate, robust. Head, front lobe of pronotum, seutellum and un- 

 der surface dull black, more or less clothed with fine appressed yellow- 

 ish pubescence, all except under surface and also the front femora bear- 

 ing numerous long, erect brownish hairs ; hind lobe of pronotum piceous, 

 with usually the hind angles and three short stripes on middle paler; 

 corium in great part piceous-brown, its costal margin to transverse 

 dark bar and a small spot opposite apex of clavus, pale yellow; membrane 

 fuscous, with a small pale spot near tip of corium; antennas with first 

 joint, usually the tips of second and third and apical half or more of 

 fourth, fuscous, remainder pale yellow; legs pale yellow, the greater 

 part of fore femora and apical fourth of the others, except knees, black. 

 Pronotum with front lobe subglobose, distinctly narrower and but little 

 longer than hind one, the latter sparsely irregularly punctate. Seu- 

 tellum much longer than wide, disk punctate along the sides and near 

 base, a vague median transverse elevation and apical longitudinal keel 

 smooth. Front femora with lower inner edge armed with two long 

 teeth and several smaller ones between and in front of them. Length,

Dunedin, Fla., Dec. 1 — April 3. Frequent on both islands 

 and mainland ; on the former taken from between the leaf -axils 

 and stems of a tall thistle ; on the latter by sweeping in open 

 pine woods and especially by beating dead leaves of cabbage 

 palmetto along the edges of gardens. A species of southern 

 range, described from Cuba and previously recorded from Ft. 

 Myers, Biscayne Bay and Lake Worth, Fla. Known also from 

 Texas, Mexico, Venezuela and Brazil. The elytra in my speci- 

 mens are mainly fuscous, not "pale stramineous yellow" as 

 described by Barber (1921a, 110). The end of the dark trans- 

 verse fascia across them is oval or rounded in outline and does 

 not attain the extreme edge of costal margin.
