348 MEMOIRS ON THE COLEOPTERA 



sides convex but scarcely cariniform, the strong postero-marginal 

 puncture very slightly in advance of the obtuse hind angles; elytra 

 three-fifths longer than wide, a fifth wider than the prothorax, the 

 sinus short and shallow but distinct; sides arcuate, very moderately 

 reflexed, striae moderately impressed and with moderate though 

 very distinct and rather close-set punctures, the seventh finer but 

 punctate, the scutellar more or less evident though comminuted. 

 Length (cf 9 ) 12.0-13.0 mm.; width 4.2-4.5 mm. Arkansas. 



Four examples incisa Lee. 



Sides of the prothorax less rounded and more regularly oblique from apex 

 to constriction, the latter very broadly rounded and in no way ab- 

 rupt, the extremely short sides thence to the angles really forming 

 part of the sinus. Body not quite so elongate and more convex 

 than in the preceding, deep black, the legs piceous-black; elytra 

 highly polished in the male; head with rather long neck, somewhat 

 elongate, nearly three-fourths as wide as the prothorax; eyes rather 

 prominent, the anterior sulci long, slender, perfectly straight and 

 feebly converging; antennae rather long, piceous, not much stouter 

 basally; prothorax a third wider than long; base transverse, sinuate 

 medially; apex feebly sinuate; surface with some transverse wavy 

 rugulation, the anterior impression very feeble, the posterior scarcely 

 evident medially; median stria abbreviated basally but almost at- 

 taining the apex; fovese large and broadly impressed, the inner in- 

 cised curved line interrupted basally, the part along the basal mar- 

 gin evident and the external line deep as in the preceding; elytra 

 one-half or more longer than wide, almost as in the preceding, ex- 

 cept that the scutellar stria is obsolete and the intervals are more 

 convex, the striae deeper. Length (o 71 ) 11.8-12.3 mm.; width 4.25 

 -4.4 mm. Pennsylvania. Two examples fausta n. sp. 



Having been obliged to make the above identifications of 

 LeConte's species from the very short and undiscriminative original 

 descriptions, as stated above, it may be that some of them do not 

 strictly accord with the types; it would be scientifically advanta- 

 geous, however, if under the circumstances, the identifications here 

 used could be made the permanent record of these species, especially 

 as original type labels in the LeConte cabinet are known in many 

 cases to have been shifted accidentally from one specimen to an- 

 other during the many years of its existence. At any rate, the 

 above descriptions are full enough for identification and embody 

 passably well all the characters originally published by LeConte. 



Cyclotrachelus Chd. 



There is at hand at present but a single species assignable to 

 this genus, and to avoid ambiguity, I have therefore assumed it 

 to be typical. Roticollis seems to be peculiar to southern Florida
