Habitat Teneriffam, a W. D. Crotch semel reperta ; forsan ex alienis 

 introducta. 



A single specimen of a Haltica which was taken by Dr. Crotch, 

 during the spring of 1862, in Teneriife appears to me to present no 

 diiferences of sufficient importance from the H. variipennis of Medi- 

 terranean latitudes to warrant its separation therefrom. Judging 

 from two examples of that insect which have been communicated by 

 M. Allard, the Canarian individual seems merely to be a little larger, 

 and to have its two longitudinal testaceous elytral bands somewhat 

 broader and more developed (so as to extend over a larger space, and 

 to be less scooped out externally) ; but in its depressed, finely punc- 

 tured surface and general colouring, as well as in the enlarged fifth 

 joint of its antennae, and in the apices of its elytra being, separately, 

 a little rounded off, it agrees entirely with the variipennis. 



(Subgenus Aphthona, Chev.)

Aphthona Paivana, Allard, Ann. de la Soc. Ent. de France, 333 (1862). 



Habitat in Lanzarota, Canaria, Teneriffa et Hierro, foliis Euphor- 

 biarum gaudens. 



This beautifully metallic species (which, however, is very variable 

 in tint, shading off from bright cyaneous-blue into golden-green, or 

 even into coppery-brown, whilst the tibia3 and tarsi, and sometimes 

 the four entire anterior legs, are testaceous) is peculiar to the foliage 

 of the various Euphorbias — on which I have taken it abundantly in 

 the north of Lanzarote (where it was found also by Mr. Gray), on 

 the mountains above San Mateo in Grand Canary, near the Puerto 

 Orotava in Teneriffe, and in the region of El Golfo on the western 

 side of Hierro. From Teneriffe it has likewise been communicated 

 by the Barao do Castello de Paiva, after whom the species was ori- 

 ginally named. M. Allard states concerning it, " Cette espece est 

 tres-facile a reconuaitre a sa couleur d'un vert ou bleu elair, a sa 

 ponctuation extremement forte et ruguouse, et a sa forme etroite et 

 lua peu aplatie qui la rapprocho de VA. FoiipilUeri, mihi."
