new Species c)/'IIistcrifla\ 1)7 



s])aringly punctured on tlie apical marj^in, by the propygidium 

 heiu^ wholly punctured on the disk and not at the sides only, 

 and by the third and fourth abdominal segments being trans- 

 versely punctured. L. yucatecum has sometimes, but rarely, 

 the second dorsal stria complete, but this variety was not 

 known to Marseul. 



IIyposolenus, gen. nov. 



Body oval or oblong-oval, somewhat convex ; head retrac- 

 tile ; mandibles dentate ; labrum narrow and transverse ; 

 forehead striate ; antenna, scape long and bent ; thorax 

 transverse, lateral stria strong and abruptly terminating after 

 ]jassiiig the anterior angle ; prosternum bistriate ; meso- 

 sternum with a deep anterior marginal furrow; pygidiuin 

 convex and closely punctate. The other characters agree 

 with those oi Plcesius, in which genus the species Icevigntus, 

 ]\Iars. (tyj)e), and hecis, bengal ensis,Si\\(\. /lamatus, Lew., have 

 been hitherto included. 



Apoblefes pcenalis, sp. n. 



Ovalia, dcplanatus, niger, nitidus ; fronte excavata, punctulata ; 

 clypeo transverse, margine late sinuato ; pronoto latoribus sub- 

 rugose punctato, stria marginali autice iuterrupta ; elytris striis 

 dorsalibus 1-3 iiitegris, 3 siuuata, -4 apicali, cteteris nullis ; pro- 

 pygidio puuctato in medio excepto ; pygidio toto profimde puiic- 

 tato ; mesosteruo stria marginali haud interrupta.

The above is similar to A. cavifrons, Lew., in that the 

 mesosternal stria is complete. A. excavatus and fariatusy 

 Lew., Schaumi and tener, Mars., belong to the same group, 

 and the six species all closely resemble one another, but in 

 the last four the mesosternal stria is interrupted. The type 

 example of A. excavatus h.as the third dorsal stria interrupted, 

 but in a longer series the stria is complete and in several the 

 pygidium is dee])ly foveolate on each side at the base.

 lato ; pygidio basi transvorsim punctato; prostcriio lato haud
