470 CANARIAN COLEOPTERA. 



Blaps gages, WulL, Ins. Mad. 506 (1854). 

 , M, Cat. Mad. Col. 157 (1857). 



Habitat in Lanzarota, Canaria, Teneriffa et Goniera, in tenebris 

 la tens. 



The European B. gages, which occurs likewise in the Madeiran 

 Group, as well as at the Azores and on the rocks of the Salvages, 

 will iu all probability be found universal throughout these islands ; 

 nevertheless hitherto I have myself detected it only in Lanzarote, 

 Grand Canary, and Teneriffe ; but it has been communicated by the 

 Barao do CasteUo de Paiva from Gomera, In Teneriffe it was taken 

 also by M. Hartung. 



708. Blaps alternans. 

 Blaps alternans, Bridle, in Webb et Berth. (Col.) 68 (1838). 

 , Hartuny, Gedoy. Verhaltn. Lanz. und Fuert. 140. 



Habitat Lanzarotam et Fuerteventiu-am, sub lapidibus magnis nec- 

 non in cavernis tufae, in montibus, congregans. 



This large Blaps, at once remarkable for its elytra being densely 

 roughened, or asperated, and closely beset with longitudinal ridges, 

 the alternate ones of which have a tendency to be more developed 

 than the remainder (a peculiarity which is more expressed in some 

 examples than in others), seems to be confined, so far at least as has 

 been observed hitherto, to Lanzarote and Fuerteventura — where it 

 congregates beneath slabs of stone, and in small basaltic caverns, on 

 the mountain-slopes of intermediate elevations. Under such circum- 

 stances I have captured it in profusion on the hills above Haria, in 

 the north of the former, in which island it was likewise found by 



M. Hartung. 



709. Blaps similis. 

 Blaps similis, Lat, Hist. Nat. Crust, et Ins. x. 279 (1803). 



fatidica, Sturm, Deutsch. Fnu, ii. 205 (1807). 



, Bridle, in Webb et Berth. (Col.) 68 (1838). 



fatadica, Woll, Ins. Mad. 508 (1854). 



, Id., Cat. Mad. Col. 157 (1857). 



Habitat Fuerteventuram et Teneriffam (circa domos), forsan ex 

 alienis introducta. 



This common European insect, which occurs likewise in the Ma- 

 deiran Group and at the Azores, seems to be scarce in these islands ; 

 though, being, in all probability, a mere introduction from more north- 

 ern latitudes, it would very likely bo found abundantly in the houses 

 and warehouses, if carefully searched for. The only examples, how- 

 ever, which I happen to possess are from Fuerteventura and Teneriffe 

 (in the latter of which it was found by M. Hartung).
