articuli 2 1 . Caput mediocre, nullomodo rostrato-deflexum, tuberculis 

 frontalibus evidentis, sat distantibus. Antenna breviusculas, apice for- 

 titer clavatse, u -articulate, basi distantes. Prothorax cordatus. Pro- 

 sternum magnum; coxa anteriores robustse modice exsertse. Troch- 

 anteres intermedii breves, ut femoris apex cum coxa articula est. 

 Coxae posteriores prominentes basi fere contiguae. Abdomen sat elon- 

 gatum, minus deflexum, marginatum, segmentis ventralibus sex, quorum" 

 primo vix conspicuo. Pedes robusti modice elongati, tarsis unguiculo 

 unico valido. 



This is a genus of considerable interest, for it indicates, in a clear 

 manner, that the position assigned by Leconte to the genus Batrisius 

 is the correct one, viz., at the end of the true Pselaphini, so as to be 

 near the Euplectini. The genus is indeed quite intermediate between 

 the two genera, fiatrisius and Euplectus, and seems to me to indicate 

 that the division of the Pselaphida into two main groups, Pselaphini and 

 Euplectini can scarcely be maintained.

Antennce stout in the male, moderate in the female, about as long as 

 head and thorax, basal joint only a little elongate ; second joint stout, 

 bead-like, about as long as broad ; joints three to six short, bead-like ; 

 joints seven and eight in the male short and very transverse, in the 

 female scarcely differing from the preceding joints ; ninth joint in the 

 female broader, but scarcely longer than the eighth, in the male 

 extremely large, sub-quadrate and impressed on the inner side at the 

 extremity ; tenth joint short and transverse in both sexes ; eleventh joint 

 stout, obtusely pointed, moderately long, in the male slightly stouter 

 than in the female. Head rather small (smaller in the female than in 

 the male sex), considerably narrower than the thorax, the frontal 

 tubercles quite distinct, short, flattened and shining, rather widely 

 separated ; the vertex is elevated, and on each side has a fovea con- 

 fluent in front with a frontal depression, so that the vertex portion of the 

 head forms a triangle projecting into a large frontal depression. The 

 thorax is narrower than the elytra, not so long as broad, the sides 

 rounded in front and considerably narrowed behind ; in front of the 

 base is a deep transverse impression, which commences on each side in 

 a large fovea, from which there proceeds forwards a longitudinal im- 

 pression ; on the middle of the transverse basal impression is placed a 

 very large fovea or depression, from which a moderately distinct channel 

 proceeds forwards, but does not reach the front of the thorax; the
