neio Species q/'Histerida3. 481 



Mesosternum with a fine entire marginal line, surface coarsely 

 and moderately densely punctured. Legs rufous. Anterior 

 tibise with four or five minute teeth, the middle with two 

 larger teeth; posterior finely bispinose, the upper spine, which 

 is near the middle, very small. 



" L. -08 inch; 2 mm. 



" A more robust species than americaniis and less coarsely 

 punctured, and differing especially in the dentation of tlie 

 tibise. The colour-character is of secondary importance, and 

 while the three specimens before me are alike, it is possible 

 that others will occur entirely black. 



" Collected by j\Ir. H. K. Morrison in Western Nevada." 



All the specimens I have seen have red elytra. 



DiPLOGRAMMICUS, gen. nov. 



Body oblong, somewhat convex, punctulate above ; elytra 

 with three dorsal strise, third sometimes broken, depressed in 

 the sutural area; propygidium convex, not impressed nor 

 uneven ; prosternum bistriate ; mesosternum marginate 

 anteriorly. The other characters correspond with those of 

 Ornalodes, of which genus omega, Kirb., is the type. 



The species to be included in JDiplogrammicus are eheninus 

 [Omalodes) , Er., type, Marseuli, Sch., and intermedins, Lew. 



Diplogrammicus intermedius, sp. n. 



Oblongus, parum parallelus ; fronte impressa stria retrorsum angu- 

 lata ; pronoto lateribus et anterioribus dense punctato ; elytris 

 striis 1-3 dorsalibua integris ; propygidio pygidioque dense 

 punctatis ; prosterno in medio bistriato. 



L. 9 mill. 



Oblong, somewhat parallel laterally, black and shining; 

 the head impressed longitudinally, stria complete, turning 

 backwards in the middle, surface rather densely punctured ; 

 the thorax densely punctured laterally, less distinctly behind 

 the head, and the points gradually lessen to the disk, scutellar 

 region smooth, the lateral stria is not well-marked owing to 

 the encroachment of the punctuation and it ceases at the 

 posterior angle. The lateral strise of Marseuli, Sch., is well- 

 marked and turns inward at the base and passes the angle. 

 The elytra are finely not closely punctulate (more distinctly 

 so than in AJarseuh), the striae 1-3 are complete, but the 

 third is somewhat irregular in its course, the others are 

 wanting ; the propygidium is coarsely punctured and some- 

 what gibbous along the sides; tlie pygidium is similarly
