new Species of Ilisteridoe. 267 



Eretmotus ccesariensisj sp. n. 

 Orbicul iris, coavexus, niger, niticliis ; fronte dense punctata ; pro- 



sterno rugoso-punctato ; mesosterao stria marginali arcuata ; 



femoribus conspicue punctatis . 

 L. 2i mill. 



Orbicular, convex, black and shining; antennae and legs 

 piceous ; the head, forehead flat, lateral striae cariniform, 

 surface somewliat opaque and closely punctured, punctures 

 most dense and somewhat rugose near the eyes ; the thorax, 

 anterior angles obliquely truncate, densely punctured behind 

 the anterior angles and along the border behind the neck, and 

 some of tiie points are ocellate, even on the disk the punctures 

 although smaller are close together ; the elytra, outer humeral 

 stria is carinate, particularly at its base, and it extends beyond 

 the middle and posteriorly nearly touches the inner humeral, 

 the latter is complete and markedly cariniform at the base, 

 but fine posteriorly, 1 dorsal very fine, but is traceable as 

 complete, 2 fine and dimidiate, 3 obsolete, surface finely and 

 sparingly punctulate, some of the points are aciculate ; the 

 pygidia are evenly but not densely punctulate ; the pro- 

 sternum is densely and somewhat rugosely punctate, some of 

 the points being confluent, the strise are widely sinuous and 

 are evanescent, or obliterated by the density of the sculpture, 

 before the suture ; the mesosternura is prominent, and the 

 stria behind it is rather narrowly arcuate, the sternal foveee 

 are deep and nearly circular in outline ; the femora are 

 densely and conspicuously punctured. 



This species is most similar to E. Bedeli in the form of 

 the mesosternura, but the mesosternal stria is more arcuate, 

 the femora are punctured and the prosternal keel rugosely 

 punctured. In E. Bedeli the femora are smooth, and the 

 punctures in the keel free of rugosities. E. sociator is some- 

 what similar also, but it differs from both E. ccesariensis and 

 Bedeli in having the mesosternal outline and stria more 

 widely arched, and also in its femora being less distinctly 

 punctured. 



Hah. Bou Berak, near Dellys, Algeria. Discovered by 

 Dr. Chobaut, associated with Aphanogaster testaceopilosa. 



Notodoma saturum, sp. n. 

 Globosum, rufo-castaueum, nitidum ; froufce punctata, stria antice 

 retrorsum acuminata ; pronoto lateribus conspicue puuctatis ; 

 clytris striis teiiuiter impressis, 1,2,4 et suturali integris, 4 cum 

 suturali basi arcuatim junctis, interstitiis parce et Isevissime punc- 

 tulatis ; metasterno stria arcuata, crenulata ; tibiis anticis 12- 

 spinulosis.
