236 Mr. G. Lewis on Eretmotus and Epiechinus. 



8. Eretmotus tangerianus, Mars. (PI. XIX. fig. 7.) 



I have Marseul's type of this species, but the drawing has 

 been made from a more recent specimen I took at Tangier. 

 The prosternal striae are very short. 



Salient Characters of the Species. 



E. corpulentus. — Broad and robust j punctures throughout 

 extremely fine. 



E. Lucasi. — Less robust ; punctures throughout more 

 distinct. 



E. cirtensis. — Inclined to be oblong ; prosternal strise closer 

 together and clearly reaching the suture. 



E. sociator. — Thorax transverse ; prosternura thickly covered 

 with ocellate punctures. 



E. kahylice. — Thorax densely punctured externally ; prosternal 

 striae sinuous rather than divergent. 



E. Bedell. — Very similar above to habylice; prosternura 

 closely resembles the figure given for sociator^ Coq. 



E. Leprieuri. — A small species with short rugose prosternura. 

 The only species not found with Aph. testaceo- 

 pilosa. 



E. tangerianus. — Prosternal strife nearly obsolete. 



Epiechinus. 



All the members of this genus are more or less squamous, 

 and to show the sculpture of the sterna given in the figures 

 the scales have been carefully removed.
