CANARIAN GROUP. 451 



conostoma as at all events a slight geographical phasis of the 

 umbUicata, and treat it accordingly ; but I fail to perceive that 

 it merits any further degree of separation. 



As thus understood, the P. umbilicata (which is represented 

 in the Canarian Group by only the ' var. /5. anconostoma ') has 

 been detected hitherto in Fuerteventura, Teneriffe, and Hierro ; 

 but we may be tolerably sure that future researches will bring it 

 to light elsewhere in the archipelago. As at Madeira, it is 

 essentially characteristic of the cultivated districts, often 

 abounding about old walls and other buildings, amongst the 

 (7acus-grounds, and elsewhere around the enclosures and towns. 

 In Teneriffe it was met with in profusion by Mr. Lowe on a 

 wall between the Puerto Orotava and Realejo, as well as by the 

 Baron Paiva at Laguna and Souzal ; and I obtained it under 

 similar circumstances in Hierro. We did not find it in the 

 other islands, but Mousson records its discovery in Fuerteven- 

 tura by Fritsch* 



I have little doubt that the Pupa which was described by 

 Dr. H. Dohrn from the Cape Verdes, as the P. Milleri (a title 

 which has subsequently been altered by Pfeiffer into P. Dohrni, 

 the name Milleri having been preoccupied), is but another very 

 slight geographical modification of the widely-spread P. um- 

 bilicata (which has established itself also even at St. Helena) ; 

 though, out of deference to the opinion of Dr. Dohrn, I have 

 retained the species as distinct.

I met with several examples of a Pupa which appears to be 

 specifically identical with the European P. granum, in the 

 three eastern islands of the Canarian archipelago, namely, (on 

 March 15th, 1859) amongst stones and scorias on a dry rocky bank 

 near the coast, below Haria (in the direction of the Llanos de 

 Temise), in the north of Lanzarote, where it was afterwards 

 obtained likewise by Mr. Lowe ; near Sta. Maria Betancuria in 

 Fuerteventura ; and on an arid slope, about midway between 

 Maspalomas and Juan Grande, in the south of Grand Canary.
