PTINID^E. 213 



Genus 192. PTINUS. 

 Linnseus, Syst. Nat. ii. 565 (1767). 



605. Ptinus testaceus. 



Ptinus testaceus, Oliv., Ent. ix. 8 (1790). 



advena, Woll, Ins. Mad. 261 (1854). 



testaceus, De Boield. , Ann. de la Soc. Ent. de France, i v. 654 (1857) . 



Woll, Cat. Mad. Col 89 (1857). 



, Id., Cat. Can. Col. 239 (1864). 



Habitat Maderenses (Mad.) et Canarienses (Hierro), ex alienis intro- 

 ductus ; circa domos mercatorumque repositoria parce occurrens. 



The European P. testaceus occurs sparingly, about houses and 

 stores, both at the Madeiras and Canaries, where it has doubtless 

 become established accidentally through the medium of commerce. 

 I have captured it in Madeira proper, of the former, and in Hierro, 

 of the latter ; but it is decidedly scarce. 



606. Ptinus brunneus. 



Ptinus brunneus (Meg.), Dufts., Fna Austr. iii. 65 (1825). 



, De Boield., Ann. de la Soc. Ent. de France, iv. 649 (1857). 



f Woll., Cat. Mad. Col. 89 (1857). 



Habitat Maderenses (Mad.), in locis similibus ac prsecedens et certe 

 introductus. 



Taken by myself in Madeira proper, the species being in precisely 

 the same predicament as the last one clearly introduced, and 

 perhaps become naturalized, through human agencies. 



607. Ptinus variegatus. 



Ptinus variegatus, Rossi, Mant. Ins. 20 (1792). 



mauritanicus, Lucas, Col. de VAlgerie, 208 (1849). 



, Woll, Ins. Mad. 261 (1854). 



, Id., Cat. Mad. Col 90 (1857). 



Habitat Maderenses (Mad.}, sub lapidibus in inferioribus, praecipue 

 in cavernis tufae apertis, sese occultans. 



Not uncommon in the low, or but slightly elevated, districts of 

 Madeira proper, occurring for the most part beneath stones (par- 

 ticularly in the open basaltic caves near the coast), though occasion- 

 ally under the dried masses of Sempervivum which stud the perpen- 

 dicular rocks ; but it has not yet been observed in the Canarian 

 Group. It is a species of Mediterranean latitudes, being found in 

 the south of Europe and the north of Africa.
