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

 and it is clear that PacJnjcraTus brevipennisy Lew., is con- 

 generic with them. 



Omalodes tuberosus, sp. n. 



Breviter ovatus, parum convexus, nigcr, nitidus ; fronte impressa, 

 stria rctrorsum acuminata ; pronoto ad augulos minute punctu- 

 lato, stria marginali integra ; elytris striis dorsalibus l-2iutegris, 

 3 punctiformi, humerali externa nulla, interna brevi cum prima 

 dorsali apice connexa ; pygidio propygidioque dense subtiliter 

 punctulatis, hoc margine postico tuberculis duobus fortibus, duo- 

 busque lateribus minus elevatis ; prostcrno in medio bistriato ; 

 mesoaterno antice profunde emarginato et utrinque sinuato, 

 stria marginali late interrupta ; tibiis anticis 4-dentatis.

Tins species differs from 0. tuberculipygus, 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 niesosternnm being sinuous on 

 either side of the median emargination. Li a type specimen 

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

 the mesosternal marginal stria is complete.

Campijlorhabdus su)yulari,-<, Sell. Ent. Nochr. xv. p. .'566 (1889). 



By tlie kindness of Herr H. 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 

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

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

 narrow behind the coxfe, with two short unconnected stria?, 

 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 Campylor/iabdits. The 

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

 1 made some years ago when the type specimen was kindly 

 lent to mc by the author. Tiic type is now in Ilerr J.
