AMERICAN COLEOPTERA. 415 



not visil)le. Elytra ventricose, widest at or heliind the middle, not 

 obviously wider at the base than tht- protliorax, striate and punc- 

 tured ; pyyidiuni inflexed, anterior ami middle coxal cavities not 

 widely se|)arated, not entirely closed within ; prosternuni short in 

 front of the coxa3, ante-coxal ridges prominent, acute , inesosternum 

 feebly excavate, nietasternum short, perpendicularly declivous in 

 front ; anterior and middle coxie prominent, posterior widely sepa- 

 rated ; second ventral segment longer than the two following united, 

 the third widi'ly attaining the lateral margin. Legs rather long; 

 thighs, at least the posterior, toothed ; tibire slender, widened at the 

 a[)ex, tarsi moderately stout, third joint broadly bilobed, fourth 

 shorter than the two preceding joints united, claws armed with a 

 long tooth. 



The pectoral canal is solely formed by the separated anterior and 

 middle coxre, the mesosternum is slightly concave, the jwsterior limit 

 being formed by the mesosternum and the perpendicular nietasternum 

 conjointly. Dr. LeConte describes the femora as mutic, which is 

 erroneous; the tooth, while small on the anterior pair, becomes quite 

 distinct on the middle, and still more so on the hind thighs. 



I have to add a second species to the one described by LeConte. 



Prothorax not much wider than lonj^, not wider at the base than at the middle, 

 elytra with distinct humeral callus, a distinct elytral fascia. PI. xiii, i\^. 19.

A. veiiti'icoMUN Lee. PI. xiii, fijrs. 19. 19a. — Ovate, convex, piceous, an- 

 tenme and lej^s rufous, thinly clothed with fine pubescence, thoracic vitta?, scu- 

 tellar spot and transverse fascia of small, oval, whitish scales. Beak punctured 

 throughout, subglabrous, indistinctly striate each side in its basal half, first .joint 

 of autennal funicle robust, second elongate, slender, following joints short, club 

 ellijitic, acuminate. Head coarsely i)unctu red, sparsely pubescent ; i)rothorax a 

 little wider than long, less than one-fourth wider at the base than at the apex, 

 sides nearly straight, suhi)arallel for one-half their length, feebly rounded ante- 

 riorly, broadly impressed in front, apex scarcely constricted, dorsal channel dis- 

 tinct, becoming wider in front, disc coarsely punctured, punctures more crowded 

 on the sides and behind the apical margin, each bearing a short hair, median vittn 

 and one each side, of pale scales. Elytra scarcely wider at the base than the 

 jirothorax, oval, very convex, humeri oblique, callus distinct, sides rounded and 

 subconjointly rounded at the a])cx, strise well impressed, shining, strongly and 

 closely iMinctured, interspaces wider than the stria% flattened on the disc, more 

 convex on the declivity, rugose, alternately a little wider; a very coi)Si)icuous 

 white scutellar line, a suboblique fascia before and a tniusverse one behind the 

 middle, less conspicuous; tliese fasc.ias are formed by short lines on the inter- 

 spaces, those on the wider interspaces are placed a little in advance of the others,
