PLATYSOitlA Leach. 

 The following species is allied to lecontei: — 



P. tabella n. sp. — Oblong, broad, parallel, depressed, liiglily polished, 

 impnnctate except along the sides of the pronotum, where the punctures are 

 rather small but deep and sparse, closer smaller and more uneven near the 

 apical angles. Head broadly, feebly concave anteriorly ; stria fine but entire, 

 convergent toward base. Prothorax not quite twice as wide as long, the sub- 

 marginal stria entire coarse and deep; transverse apical stria extending to the 

 apical part of the subniarginal, where it is feebly reflexed. Elylra three- 

 fourths longer and scarcely visibly wider than the prothorax ; inflexed flanks 

 closely bisulcate ; humeral stria feeble, diverging but slightly from the first 

 dorsal ; dorsals rather fine but deep, impunctate, the first four entire ; fifth 

 and sutural short, not quite extending to the middle. Propygidium rather 

 coarsely but sparsely punctate, finely so in the middle ; pygidium rather 

 coarsely but sparsely punctate, the punctures shallow and becoming small 

 toward tip. Prosternal lobe large, very broadly rounded, minutely margined 

 at apex ; mesosternum broadly, distinctly sinuate at apex, the marginal stria 

 fine but entire. Anterior tibiae acutely and strongly 4-dentate. Length 4.0 

 mm. ; width 2.0 mm. 



Indiana ? 



Differs from lecontei not only in its larger size, but in the per- 

 fectly entire fourth dorsal stria and in the apical angles of the pro- 

 thorax, which are less transversely rounded and more anteriorly 

 prominent. The locality is possibly somewhat doubtful, as the 

 single specimen had no label in the Levette cabinet. There is no 

 corresponding Mexican species however. 



KPIERIJS Erichs. 



The species of Epierus present but little diversity of appearance, 

 but may be readily separated by the following structural charac- 

 ters : — 



Elytra with all the striae entire, the fifth and especially the sutural, some- 

 times very feeble or obsolescent toward base. 

 Fifth dorsal and sutural striae distinct and strong to the base. 



Inflexed flanks of the elytra strongly bisulcate ; body strongly convex. 

 Form broadly oval ; pygidium extremely finely and feebly punctulate ; 

 prosternal striae widely separated {nigrellus Say). 



regiilaris Beauv, 



Form more narrowly oval ; pygidium distinctly but sparsely punctate 



anteriorly; prosternal striae narrowly separated and less divergent 



anteriorly TicinilS Lee.
