nearer to each other in this species than in any other known, 

 and the general outline is less orbicular. 



I obtained a small series of this species in the fir-woods 

 above Constantine and a single example at Bone, on the road 

 to La Calle and Guelma. 



4. Eretmotus sociator, Coq. (PL XIX. fig. 4.) 



The figure is drawn from an example kindly given to 

 me by Mons. L. Bedel, and is from Daya. The thorax is 

 more transverse than in the other species and the pro- 

 sternal punctures are distinctly ocellate, as shown in the 

 Plate. Coquerel says nothing about the prosternum, except 

 that it is " saillant ; " but Marseul redescribed the species 

 from an example in Fairmaire's colle-^tion, and in the diag- 

 nosis he says " prosterno dense punctato," and in the text 

 following " prosternum rugueux." Coquerel studied this 

 species so slightly that he made a genus for it, although he 

 knew of Marseul's genus Eretmotus^ and even writes about it 

 and says it has a certain analogy to Eretmotus, and differs in 

 the relative width of the mesosternum — and this it does not 

 do. The species has frequently been assigned erroneously to 

 Fairmaire. I have no doubt about the identification of this 

 species, yet Coquerel speaks of the " thorace elytrisque sub- 

 tilissime punctatis ; " but under the microscope the thorax is 

 strongly punctate, especially at the sides, where the punctures 

 are often ocellate. 



5. Eretmotus kahylice, sp. n. (PI. XIX. fig. 5.) 



Orbicularis, convexus, niger, nitidus ; capita ocellato-punctato ; 



thorace lateribus vix dense punctato ; prosterno carinis modice 



punctato sinuatis. 

 L. 2| mill. 



Orbicular, convex, black, shining, the legs and antennas, 

 like all the species, rufo-piceous ; the head rather densely 

 punctured, feebly impressed before the clypeus ; punctures 

 ocellate or subocellate, lateral carina rather strong, feebly 

 sinuous, the thorax somewhat densely punctured at and behind 

 the anterior anglers and behind the head, punctures gradually 

 becoming fine and' scattered towards the disk ; anterior angles 

 moderately produced ; posterior fovea shallow and somewhat 

 triangular ; the elytra finely punctulate throughout, first and 

 second strise visible for two thirds of elytra, third obsolete ; 

 epipleural carin^e not markedly raised ; propygidium and 

 pygidium finely punctulate. The prosternum, strise widened
