new Species o/Histevidfe. 97 



sparingly punctured on the apical margin, by the propygidium 

 being wliolly punctured on the disk and not at the sides only, 

 and by the third and fourth abdominal segments being trans- 

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

 the second dorsal stria complete, but this variety was not 

 known to Marseul. 



Hyposolenus, 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 

 passing the anterior angle ; prosternum bistriate ; meso- 

 sternum with a deep anterior marginal furrow ; pygidium 

 convex and closely punctate. The other characters agree 

 with those of Plcesius, in which genus the species kevic/utus, 

 ]\Iars. (type), and hvvis, hengaleiisis, and hamatus, Lew., have 

 been hitherto included. 



Apohlefes poenalis, sp. n. 



Ovalis, deplanatus, niger, nitidus ; fronte excavata, punctiilata ; 

 clypeo transverso, margine late siiuiato ; pronoto lateribus sub- 

 rugose punctato, stria marginaii antice interrupta ; elytris striis 

 dorsalibus 1-3 integris, 3 sinuata, 4 apicali, caeteris nullis ; pro- 

 pygidio punctate in medio excepto ; pygidio toto profimde punc- 

 tato ; mesosteruo stria marginaii haud interrupta.

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

 raesosternal stria is complete. A. excavatus and feriatus^ 

 Lew., Schaumi AXidi tener, j\lars., 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 has the third dorsal stria interrupted, 

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

 pygidium is deeply foveolate on each side at the base.

Apohhtes pumicatus, sp. n. 



Oblongo-ovatus, deplanatus, niger, nitidus, antennis pedibusque 

 piccis ; fronte plana, haud striata, impunctata ; pronoto stria 

 marginaii teuuiter impressa, brevi in angulo antico ; elytris striis 

 1-3 integris, 4 apicali, dimidiata ; propygidio disperse punctu- 

 lato ; pygidio basi transversira punctato ; prostorno lato haud 

 striato ; mesosterno bisiuuato, immarginato ; tibiis anticis multi- 

 denticulatis.
