Torre Bueno's (1939) record for Florida needs verification, and 

 may prove to Lave been based on an adventive.

Diagnosis. — The very great width of the interocular part of the 

 head, which here is greater than the length of the head, will permit 

 ready recognition of this species within the subgenus. 



Description.— Based on one male and two females. Male: Oval, 

 outline of costa not continuing nor paralleling lateral margins of 

 pronotum but more abruptly flaring posteriorly. 



Head: Length more than half width, 1.69:2.79; interocular width, 

 1.89; surface shining, with faint, radiating rugae and minute, widely 

 scattered punctures; ocelli small to moderate, separated from eye 

 by space nearly or quite equalling twice transverse ocellar width; 

 jugum ventrally and maxillary plate shining, impunctate. Antennal 

 segments: I, 0.61; II, 0.46; III, 0.80; IV, 0.73; V, 0.74. Bucculae 

 about half as high as labial II; labium surpassing posterior coxae, 

 sometimes reaching to sternite IV. Labial segments: I, 1.26; II, 

 2.06; III, 2.19; IV, 1.63. 



Pronotum: Length more than half width, 3.75:6.30; lateral margin 

 straight on basal two-thirds, with submarginal row of twelve setigerous 

 punctures; transverse impression vu-tually not impressed, marked by 

 very UTegular interrupted row of punctures; anterior lobe with inter- 

 mixed coarse and fine punctures laterally and in subapical band paral- 

 leling anterior margin, with broad, shallow basin-like depression over 

 most of middle third; posterior lobe with few minute and fewer coarse 

 punctures scattered UTegularly across width. 



Scutellum: Length more than width, 4.20:3.91; disc polished, 

 with about half dozen coarse punctures and several fine ones widely 

 scattered. 



Hemelytron: Clavus and corium shining; clavus with single row of 

 coarse punctures and several finer scattered ones; mesocorium with 

 one complete and one partial row of punctures paralleling claval 

 suture; punctation elsewhere not dense, absent medially; exocorium 

 less densely punctured than mesocorium ; costa with five or six setiger- 

 ous punctures; membrane distinctly surpassing apex of abdomen. 



Propleuron: Polished, with few small punctures in depression. 



Mesopleuron: Lateral area with few oblique rugulae. 



Metapleuron: Lateral margin of evaporatorium obhque, concave; 

 lateral area impunctate.
