CANARIAN COLEOPTERA. 163 



spinulosis et ante apicem subito dilatatis, posterioribus sxibrectis, 

 parce ciliato-spinulosis. — Long, corp, lin. |. 



Abrseus p;inctiini, Aube, Ann. tie la Soc. Ent. de France, 232 (1842). 

 Acritus pimctum, de Mars., ibid., 607 (1856). 



Habitat Lanzarotam, per oram arenosam maritimam prope oppidum 

 Arrecife sub fueis captus. 



Its oblong, entirely punctulated body, its freedom from a punctured 

 subbasal protboracic line, and tbe shape of its sterna, no less than 

 its maritime habits, prove the present Acritus to be identical with 

 the A. punctum from the south of Europe — of which I have lately 

 received four examples from A. H. Haliday, Esq., taken by himself 

 in Italy ; nevertheless many of its most important characters are 

 totally unalluded to by De Marseul. Thus, he expressly says, of the 

 punctum, " Front convexe, saillant sur les yeux"; whereas in reality 

 the forehead is depressed, and the eyes are not only large and pro- 

 minent, but also (which is a most unusual feature) minutely and 

 sparingly setose*. Again, he states, "pygidium et propygidium tres 

 finement ponctues " ; whereas there is not the vestige of a puncture 

 on that portion of the surface (which is closely and delicately trans- 

 versely-rugulose). And, lastly, he speaks of the colour of the limbs 

 as pale-testaceous ; whereas they are piceo-fernigiuous. In addition 

 to these discrepancies, I should add that he makes no mention of the 

 arcuated and rather suddenly dilated anterior tibiae, which constitute 

 one of its most conspicuous peculiarities. Nevertheless the Canarian 

 insect is clearly identical with the A. punctum ; with which (as just 

 stated) it likewise agrees in its mode of life. Indeed the only six 

 specimens which I have seen were captured, by myself, from beneath 

 sea- weed on the sandy beach close to Arrecife of Lanzarote ; and 

 in the 'Faune Frangaise' the habitat given for i]xQ punctum is "La 

 Teste, sous les algues."

* I can recall but few Coleopterous insects in which tliis structure exists ; 

 indeed the only ones that I now recollect, in which it obtains, are Litargus and 

 my genus Tarphiodes (from the Malay Peninsula).
