AMERICAN COLEOPTERA. 159 



Cymindis Latr., is the subject of an essay by Chaudoir, (Berl. 

 Zeitschr. 1873), and with three other genera constitutes the tribe Cymin- 

 dides, but I find that there are no special characters assigned to it. 



PiNACODERA Schaum, and APENES Lee, are treated by Chaudoir in 

 a paper entitled, "Genres aberrants du groupe des Cymindides," (Bull. 

 Mosc. 1875), and as there are no characters assigned to the group it is im- 

 possible to ascertain in what respect these genera are especially aberrant. 



Euc^RUS Lee, has already been referred to. 



PentaCtOXICA Schmidt-Goebel, which has for its synonyms Didetus 

 Lee, and Rhomhndera Reiche, is the subject of a short essay by Chau- 

 doir, (Bull. Mosc. 1877, i, p. 212), who says that it is "one of those 

 aberrant genera which can not be made to enter any of the groups 

 established at the present time. I believe that jMr. Bates is correct in 

 placing it in a special group under the name Pentagonicinse," (Trans. 

 Ent. Soc. London, 1873, p. 320). This is certainly an easy settlement 

 of the difficulty, more particularly as no characters are assigned to 

 the group. 



Corsyra. — This genus does not occur in our fauna. I merely 

 introduce it here to express a view that it has nothing to do with 

 Graphipterus as intimated by Chaudoir, (Bull. Mosc. 187G). The well 

 marked supra-orbital and thoracic setae, the structure of the labial palpi 

 and tibial spurs all forbid its position there. 



Onota Chd., is represented by one species found in Florida: 



O. Floridana n. sp.— Rufo-testaeeous, elytra brilliant green with extremely 

 narrow lateral and apical rufous border.. Antennae and palpi entirely pale. Front 

 with moderately deep arcuate groove within the insertion of the antennse, another 

 near the edge. Thorax as wide as the head including the eyes, as broad as long, 

 augulate in front of middle, the sides anteriorly feebly arcuate, posteriorly sinuate, 

 hind angles acute. Elytra moderately deeply striate, the striae finely punctured, 

 intervals slightly convex, smooth. Legs rufo-testaeeous. Length .20 — .25 inch ; 

 5—6.25 mm. PI. IV, fig. 4. 



Three specimens without sexual difierences are before me, collected by 

 Hubbard and Schwarz, near Lake Poinsett, Florida. 



It appears to resemble- 0. hicolor Chd., but is larger and the pale 

 border of the elytra is extremely narrow. Among our Lebiini it wUl 

 be at once known by the angulate sides of the thorax and distinct 

 hind angles. 



A fuller description of tlie genus (which is placed by Chaudoir in 

 the Callidides), will be given in a future essay on the species of the 

 present tribe. 



In concluding the Lebiini I regret to believe that the genera have 

 been inordinately multiplied, and the higher divisions whether called
