118 NOKTH AMKRICAX 



arcuate, constricted at the immediate base ; antennae robust, tenth joint more 

 than twice as long and nearly twice as wide as the ninth which is short and 

 twice as wide as long, eleventh slightly wider than the tenth, slightly longer 

 than wide, conoidal and acuminate ; last joint of the maxillary palpi longer 

 than the remaining joints together, robust, conoidal, twice as long as wide, 

 acuminate at tip. Prothorax widest slightly before the middle where it is 

 slightly wider than the head and nearly one-third wider than long, and 

 where the sides are parallel and feebly arcuate for nearly one-half the length, 

 thence abruptly and strongly convergent posteriorly and feebly sifiuate ; 

 edge finely denticulate throughout ; apex slightly more than one-half as long 

 as the pronotal width and four-fifths as long as tlie base ; disk broadly con- 

 vex, polished, and finely and sparsely jjunctulo-asperate, having near the 

 apex a deep median canaliculate puncture which becomes attenuated poste- 

 riorly terminating at the middle of the disk, also at one-third the length from 

 the base a very deeply impressed narrow transverse groove, terminating at 

 the sides in rather small deeply impressed spongy-pubescent foveae, and 

 dilated into a strong posteriorly attenuated impression in the middle ; base 

 with a minute impression at each side midway between the middle and the 

 basal angles, and also a small round puncture at each basal angle. Elytra 

 at base scarcely wider than the pronotum ; sides rather strongly divergent 

 posteriorly, strongly arcuate ; disk slightly shorter than wide, broadly con- 

 vex, polished, scarcely punctulate ; sutural striae fine, strong and very close, 

 lateral well-marked, ni^arly one-half as long as the elytra. Abdomen short 

 and broad, nearly as wide as the elytra; sides parallel and nearly straight ; 

 border narrow, inclined; surface broadly convex, polished, extremely finely 

 and remotely punctulate ; first three dorsal segments equal ; basal segments 

 not carinate at base. Legs short and slender. Length 0.8 mm.

Described tVoin Dr. LeConte's unique type. In the two species of 

 this genus the median carinae of" the prosternum and niesosternum 

 are both very narrow and well marked. 



It is to be regretted tiiat Dr, LeC'onte's deseri[)tion of this. species 

 is so short and full of error as to be quite useless for any otlier pur- 

 pose than the mere attachment of a name. In the three lines con- 

 stituting the description proper, there are no characters given by 

 which it can be distinguished from most of the other species in this 

 [)art of the genus. In the few subjoined remarks the author states 

 that it is nearly related to Ea. dijflicUls: this must surely be a slip 

 of the pen as there are scarcely any otiier two species of the group 

 in ([uestion so widely different, eitiier in appearance or structural 

 characters.

 evenly distributed, very pale, scarcely conspicuous ; color of body piceous-
