Oval, raflier convex, black and shining; tlie foreliead iia? 

 a semicircular stria ; niandihlu'S soniewliat long ; thu thor;ix, 

 lateral stria slightly hamate at the base, crenulate anteriorly 

 and sinuous behind the eyes, und there is a small antescutellar 

 puncture ; the elytra, stria?, inner humeral shortened at tli'i 

 base and rather wide and deep below the shoulders, dorsal 

 stiiic crenulate, 1-15 complete, 4 shortened at the base, with a 

 bent apj)endage, .5 dimidiate, sutural a little longer (some- 

 times the fourth and tilth are joined apically) ; the propygidium 

 is evenly but not so closely punctured as the pygidium; 

 the prosternum has two fine stria? between the coxro and the 

 anterior lobe is markedly mar;;inate; the mesosternuin is 

 leebly sinuous and the marginal stria complete ; tiie anterior 

 tibiie are 7-8-spinose. 



Closely similar to Ulster niponicus^ Lew., but the thoracic 

 margin is less wide and there are other small differences.

SriLODisCUS, gen. nov. 



Body oval, convex ; head retractile; antenna, scape long 

 and bent, tunicuius with the basal joint longer than the next 

 two together, the other joints are short and gradually enlarge 

 towards the club; the labrum is transverse or semicircular ; 

 mandibles short, robust, immarginate and obscurely dentate; 

 ])ygidium convex ; mesosternum markedly eniargiiiate ; 

 anterior tibiae dilated, with two broad teeth ; femora more or 

 less robust. 



The species to be included in this genus are all natives of 

 the New World, viz. Ilister arciiatus. Say (type), selUitus 

 and iijilut/iatus, Lee, Ulkei, lucanus, militariusj and Glovivi, 

 Horn, iiatiKjiutus, sarcinalusj tunicntusj and Fluhri, Lew., 

 ncti/jilicauJa, seniiruhtr, oreyonis, and iLcitis, Casey, and 

 siinjilicipes, Fall. In all the species the elytra are partly red 

 and in (ucanius, Horn, and tunicatus, Lew., there is a very 

 small basal tooth on the anterior tibia; but this is not 

 important, as the general form of the tibiic is the same.
