12 Mr, G. Lewis on 



assigned to this genus by Kolbe in the museum at Berlin, 

 and it is clear that Pachycrcerus brevipennisj Lew., is con- 

 generic with them. 



Omalodes tuberosus, sp. n. 



Breviter ovafcus, parum convexus, niger, nitidus ; fronte impressa, 

 stria retrorsum acuminata ; pronoto ad angulos minute punctu- 

 lato, stria marginali Integra ; elytris striis dorsalibus 1-2 integris, 

 3 punctiformi, humerali externa nulla, interna brevi cum prima 

 dorsali apice connexa ; pj-gidio propjgidioque dense subtiliter 

 punctulatis, hoc margine postico tuberculis duobus fortibus, duo- 

 busque lateribus minus elevatis ; prosterno in medio bistriato ; 

 mesosterno antice profunde emarginato et utrinque sinuato, 

 stria marginali late interrupta ; tibiis anticis 4-dentatis.

This species differs from 0. tuherculipygus, Sch., in its 

 shorter form, forehead impressed, not canaliculate, in wanting 

 a sutural stria, in the prosternal stria being shorter, and, 

 above all, by the edge of the mesosternum being sinuous on 

 either side of the median eniargination. In a type specimen 

 of 0. tuherculipygus I have received from Herr J. Schmidt 

 the mesosternal marginal stria is complete.

By the kindness of Herr IL J. Kolbe I am able to give a 

 figure (fig. 9) of the above species. Hister mtesa, Ancey, a 

 species very inadequately described, possibly belongs to 

 Campylorhahdus, and, if so, it is a far more extraordinary 

 species of the genus than G. singularis. The prosternum is 

 narrow behind the coxse, with two short unconnected strise, 

 the mesosternum is straight and wide anteriorly and the 

 marginal stria is almost rectangular on either side and is at 

 some distance from the edge. On the first segment of the 

 abdomen there is a wide transverse arched stria. The two 

 humeral striae are complete, 1-4 and sutural are also com- 

 plete and join at the base, 5 is apical and dimidiate. 

 Mons. Ancey says nothing about the legs, so it may belong 

 to another genus, but it is similar to Campylorhahdus. The 

 particulars 1 have given of Ancey's species are from a drawing 

 J made some years ago when the type specimen was kindly 

 lent to me by the author. The type is now in Herr J.
