partly incluJed in it; this character, however, Latreille, in the 

 IJegne Animal, does not state to be essential in this genus. The 

 proportion which the terminal joint of the palpi bears to the pre- 

 ceding joints, is very similar to that of the palpi figured by 

 Olivier, Vol. 3, No. 59, PI. 1, and although this terminal joint is 

 proportionally larger than that of the bipimctata, yet it is not 

 more dilated than that of TcMyria glabra, which is admitted 

 into the same subdivision with Pimclia. 



The anterior tih\s& are not dentated like those of Erodius, but 

 are furnished with small spines on the anterior and posterior 

 edges; the form of the thorax and abdomen agree with Latreille's 

 definition of Pimdia in the Regne Animal. 



[Belongs to Edrotes Lee. — Lec] [253] 



AKIS Fab. 



A. ? MDRICATA. — Black ; above with numerous small tuber- 

 cles and setae ; thorax and elytra with widely reflected margins. 



Inhabits Arkansa at the Rocky Mountains. 



Body oblong-oval, black; superior surface armed with numer- 

 ous minute tubercles, from each of which arises a small, recurved, 

 ferruginous seta : clypeus not reflected : antennae, third joint 

 nearly equal to the two succeeding ones conjunctly ; fourth, fifth, 

 sixth, seventh, eighth, joints, obconic-cylindric; ninth, tenth, 

 eleventh, rounded, the latter somewhat larger than the preceding- 

 one, and subacute at its tip: thorax transverse, dilated, and 

 widely reflected each side, widest behind ; anterior margin very 

 profoundly and abruptly emarginated, the emargination receiving 

 the head to the origin of the antennae, and rather too narrow to 

 admit the free motion of the head upward ; lateral edge simply 

 arquated; posterior edge rectilinear in the middle, excavated 

 each side ; anterior and posterior angles subacute, the latter ex- 

 tending far backwards so as to cover the anterior angles of the 

 elytra : elytra inseparably united, widely reflected each side and 

 behind, the exterior edge continuing the course of the thoracic 

 edge, without any indentation between them : wings none : scutel 

 minute : tibia armed with minute spines. [254] 



Length thirteen-twentieths of an inch.
