TROGOSITID.E. 117 



Trogosita mauritanica, Woll, Ins. Mad. 154 (1854). 



, Id., Cat. Mad, Col. 50 (1857). 



- Id., Cat. Can. Col. 121 (1864). 



Habitat Maderenses {Mad.} et Canarienses (Lanz.,Fuert., Can., Ten., 

 Crom.), in domibus et prsesertim sub recremento farris circa basin 

 acervorum tritici sparse hinc inde vulgaris. 



The nearly cosmopolitan T. mauritanica, although evidently natu- 

 ralized, is doubtless universal in the inJiabited islands of these 

 Atlantic Groups. In Madeira proper, it has been observed princi- 

 pally about the houses and stores ; but at the Canaries it is far more 

 abundant, as well as more completely established occurring not 

 only in the towns and warehouses, but (far more commonly) beneath 

 the refuse at the base of corn- stacks. Palma and Hierro are the 

 only islands of the seven in which it does not happen to have been 

 detected ; but there can be no question that it exists there, as it 

 does throughout the rest of the archipelago. In Gomera it was 

 taken by the Messrs. Crotch. 



Examples of the T. mauritanica have been communicated by the 

 Baron Paiva, professedly from the Great Salvage ; but as I have 

 little doubt they were captured amongst the provisions taken by the 

 boatmen from Fimchal, I do not consider them worth noticing. 



327. Trogosita serrata. 



Trogosita serrata, Woll., Ins. Mad. 155 (1854). 

 , Id., Cat. Mad. Col. 50 (1857). 



Habitat Maderenses (Mad.), rarissima; in insulam fortasse saccha- 

 rinis introducta. 



Occurs, though very rarely, in the houses and stores of Madeira 

 proper, where it has doubtless been naturalized through the medium 

 of commerce. By the late Mr. Bewicke it was found in sugar ; and 

 it has lately been communicated by the Barao do Castello de Paiva. 



328. Trogosita recta. 



Trogosita recta, Woll, Trans. Ent. Sue. Lond. i. 144 (1862). 

 Id., Cat. Can. Col. 122 (1864). 



Habitat Canarienses (Lanz.), semel tantum reperta. 



A Canarian species and very closely allied to the serrata, though 

 I believe truly distinct from it. Indeed its habits would seem to be 

 different, for the only example which I have seen was captured 

 within the stem of a dead Euphorbia in the north of Lanzarote.
