754. Acalles saxicola. 



Acalles saxicola, Wott., Ins. Mad. 332 (1854). 

 , Id., Cat. Mad. Col. 106 (1857). 



Habitat Maderenses (Des.), sub lapidibus in elevatis parce captus. 



Observed hitherto only on the Deserta Grande, of the Madeiran 

 Group, where I have on two or three occasions captured it from 

 within the holes (or cavities) on the undersides of stones and scoriae 

 on the high and exposed headland which forms the northern ex- 

 tremity of that island. 



755. Acalles histrionicus. 



Acalles histrionicus, Wott., Cat. Mad. Col 106 (1857). 

 Habitat Maderenses (P to S to \ semel tantum repertus. 



Hitherto unique a single example having been taken by myself 

 in Porto Santo, of the Madeiran Group, near the ruined church of 

 Nossa Senhora da Grace (above the Villa). It is the only Acalles 

 which has yet been detected in Porto Santo. 



756. Acalles pulverulentus. 



Acalles pulverulentus, Wott., Ins. Mad. 333 (1854). 

 , Id, 9 Cat. Mad. Col. 107 (1857). 



Habitat Maderenses (Mad.), in aridis subinferioribus parce lectns. 



Taken sparingly in Madeira proper at a rather low elevation, on 

 the sunny and exposed cliffs to the eastward of Funchal. Further 

 material is much required, both of this Acalles and of the following 

 one, in order to complete their diagnoses. 



757, Acalles oblitus. 



Acalles oblitus, Wott., Ins. Mad. 333 (1854). 

 , Id., Cat. Mad. Col 107 (1857). 



Habitat Maderenses (Mad.}, rarissimus ; in locis similibus ac praeee- 

 dens. 



Found in the same situation, in Madeira proper, as the last species, 

 and equally rare. Indeed it is hitherto unique ; and until further 

 (and more satisfactory) material has been obtained, I cannot feel that 

 either the A. oblitus or pulverulentus (although, I think, they can 

 scarcely be referred to any of the other species here enumerated) 

 have been properly denned.
