Dimensiom. — Length, 0.67 inch. 



North America (Serville) ; Florida (Walker). 



Division 2. — Top of the head convex and somewhat elevated ; vertex 

 broad between the eyes and strongly deflexed ; eyes globose and prominent. 

 Median carina moderately but less elevated than in the preceding division ; 

 but in this respect there is some. variation, as in some species it is very slight 

 and can scarcely be 'considered as elevated; the lateral carinas are somewhat 

 distinct, but not acute. The head is usually broader than the front of the 

 thorax, which is considerably constricted n^ar the front. 



This division appears to be more closely allied to Staiironotus than 

 either of the preceding or following divisions ; it is difficult, therefore, to 

 arrange the species in a regular, continuous series.

Occiput ascending, short; vertex broadly triangular, the central foveola 

 being almost as large as tlie occiput, a regular triangle, the base forming a 

 transverse ridge between the eyes, opening in front into the narrow sulcus of 

 the frontal costa ; frontal costa very narrow above, expanding slightly below, 

 sulcate throughout. Antennae very long, especially in the male, somewhat 

 enlarged, and slightly flattened near the base. Eyes quite prominent, suli- 

 globose. Median carina of the pronotum somewhat prominent, nearly straight 

 on top, twice notched, the posterior one about the middle, middle part short- 

 est; lateral caringe distinct on the posterior lobe; apical angle slightly acute; 

 rather more than usually contracted a little in advance of the middle. Elytra 

 and wings narrow, passing the abdomen. 



Colo?: — Ash-colored, variegated with gray and dark-brown. In the 

 males the disk of the jironotum is dark-brown in the middle, margined with 

 yellowish ; sides yellowish, with one or two dusky stripes on the front border. 

 Elytra yellowish-brown, the lower half sprinkled with small fuscous or brown 

 spots ; upper half unspotted. Wings yellow at base, varying from pale to 

 deep-yellow; a broad, black band, occupying the middle third, rather broadest 

 where it strikes the hind border, curves round nearly to the anal angle; front 

 margin dusky nearly to the base ; apical angle pellucid, except a dusky spot 

 at the tip, sometimes almost obsolete. Hind femora yellow, with three dark 

 bands; apex dark; posterior tibiae whitish, with a dark ring at each end, a 

 broad one of the same color just above the middle.
