1136. Opatrum hispidum. 



Opatrum tomentosum, De/., Cat. (edit. 3) 214 (1837). 



hispidum, Srulle, in Webb et Berth. (Col) 68 (1838). 



prolixum, Erich., in Wiegm. Archiv, 248 (1843). 



fuscum, Wott. [nee Hbst], Ins. Mad. 500, tab. xi. f. 1 (1854). 



, Id., Cat. Mad. Col. 156 (1857). 



hispidum, Id., Cat. Can. Col 488 (1864). 



Habitat Haderenses (ins. omnes) et Canarienses (ins. omnes), sub 

 lapidibus, passim. 



There is no insect more general throughout these Atlantic Groups 

 than this Opatrum, in all the islands of which (namely, the five Ma- 

 deiran and the seven Canarian ones), except those of the Salvages, 

 it has been captured more or less abundantly. It is likewise com- 

 mon at the Cape de Verdes. In my ' Ins. Mad.' and Madeiran 

 Catalogue I erroneously regarded it as the fuscum (or rusticum) of 

 southern Europe ; which led me into the further mistake of describ- 

 ing the latter (under the name of errans) as a new species. 



1137. Opatrum oblitum. 

 Opatrum oblitum, Wott., Cat. Can. Col. 489 (1864). 



Habitat Canarienses (Lam., Fuert.), in aridis arenosis et calcariis, 

 praesertim submaritimis, occurrens. 



A rather small species (somewhat allied to the 0. pygmceum of 

 southern Europe) which occurs at low elevations in the two eastern 

 islands of the Canarian archipelago, Lanzarote and Fuerteventura ; 

 and I likewise met with it on the little islet of Graciosa, off the north 

 of the former. It is found generally in sandy and calcareous spots, 

 towards the coast. 



1138. Opatrum dilatation. 



Opatrum dilatatum, Woll, Ins. Mad. 501 [note] (1854). 

 , Id., Journ. ofEnt. i. 91 (1860). 



Habitat Salvages (ins. minor em, australem), a Dom. Leacock semel 

 deprehensum. 



The only example which I have yet seen of this distinct Opatrum 

 was taken on the southern of the two islands of the Salvages (known 

 as the " Great Piton "), in 1851, by Mr. Leacock of Madeira. 



Genus 342. MELANSIS. 

 Wollaston, Cat. Can. Col. 491 (1864).
