than twice as wide as long, widest at base, sides arcuate, 

 margin not fimbriate, hind angles acutely prolonged be- 

 hind, disc convex, absolutely impunctate. Elytra smooth 

 impunctate, without marginal edge. Epipleuras gradu- 

 ally and but little wider at base, absolutely smooth. Pro- 

 sternum coarseh' punctured between the coxa?, the tip 

 rounded and with a distinct marginal bead. Abdomen 

 ver}' sparsely and finely punctate, shining. Length, .37- 

 .40 inch; 9—10 mm. 



This species could not be mistaken for an}^ other, ex- 

 cept (ill bins, from which it differs in its smooth surface, 

 nearly entire clypeus and margined presternum.

EUSATTUS CILIATUS n. Sp. 



Oval, convex, black moderately shining, slightly more 

 obtuse behind, margin of thorax and the legs ciliate with 

 long yellowish hairs. Head sparsely finely punctate, 

 clypeus deeply and broadly emarginate with a moder- 

 ately deep incisure each side, the entire margin of the 

 front reflexed. Thorax more than twice as wide as long, 

 much narrowed in front, sides arcuate, the margin ex- 

 planate, hind angles slightly prolonged but not acutel}^ 

 disc of thorax smooth with a few fine piliferous punctures 

 near the side. Elytra without lateral margin, surface 

 with minute sparsely placed submuricate granules each 

 with a short hair, intervals very minutely alutaceous. 

 Epipleura? gradually wider from apex to base, sparsely 

 punctate and ciliate. Prosternum sparsely punctate cil- 

 iate with yellow hairs, the tip narrowly oval with a dis- 

 tinct marginal bead. Abdomen very sparseh'' finely punc- 

 tate. Legs ciliate with moderately long yellowish hairs. 

 Length, .46 inch; 11. 5 mm. 



This species approaches niiiricatiis in form, with a 

 suggestion of Coelus from its ciliate thorax.
