PROMECOPINI. Ill 



fined, passing immediately beneath, and slightly beyond the lower border 

 of the eye, not continued beneath the beak. Antennpe moderate; scape 

 gradually clavate, slightly arcuate, passing slightly the anterior border of 

 the eye; funicle 7 jointed, 1-2 feebly elongated, the first longer than the 

 second, 3-7 gradually smaller; club oval. Thorax broader than long, base 

 slightly narrower, ocular lobes very prominent. Scutellum oval or trans- 

 verse. Elytra oblong, wider at base than the thorax, humeri oblique, sides 

 parallel. Mesosternum not protuberant. Metasternum short. Intercoxal pro- 

 cess broad, oval at tip. Second abdominal segment longer than the two fol- 

 lowing, first suture sti'ongly arcuate. Anterior and middle tibiffi mucronate 

 at tip, articular surface of hind tibiie internal, not cavernous. Claws fx'ee. 

 Body densely scaly. 



This genus may be at once distinguished from all the others of the tribe 

 by the acute emargination of the submentum. 



Two species occur in our fauna, which are distinguished as follows : 

 Scutellum transverse, twice as wide as long. Thorax 



with four discal black spaces, the two basal 



smaller. Black stripes of elytra regular pulcher. 



Scutellum smaller, oval. Thorax with two broad, 



discal, black stripes narrowly separated. Black 



stripes of elytra with irregular margins Rosenschceldi.

Form oblong, densely scaly. Head and rostrum shorter than the thorax, 

 densely covered with cupreous scales, a round spot black. Rostrum with 

 impressed median line, tip with feeble triangular impression. Thorax 

 broader than long, sides strongly arcuate in front, and gradually narrowing 

 to base, the latter slightly arcuate, disc moderately punctured, surface 

 densely covered with cupreous scales, and with four black spots; the pos- 

 terior smaller, sides of thorax cupreous, beneath the margin a black spot. 

 Scutellum transverse. Elytra oblong, moderately convex, with rows of 

 moderate punctures not closely placed; surface densely scaly, sutural inter- 

 val cupreous; a broad, black stripe slightly narrowed at its middle, and not 

 attaining the tip, at the side two oblong black spots, one humeral, the other 

 sub-apical, sometimes united in an entire stripe, limb and lateral vitta cu- 

 preous. Body beneath less densely scaly, scales pale cupreous, a black 

 spot at the side of the first two ventral segments. Legs less densely scaly, 

 femora nearly nude at apex and base. Tibiae with short, spinulose hairs 

 within. Length .16-. 33 inch; 4-8 mm. 



Two varieties occur. One has the lateral black stripe entire, in the other 

 it is broadly divided. 



Occurs usually in the first variety in Florida, and in the latter in Texas.

Form oblong oval, densely scaly. Thorax as long as wide, sides in front 

 rather suddenly convergent, posteriorly nearly parallel, disc sparsely punc- 

 tured, densely covered with cupereous scales; a broad, entire black stripe
