Mr. T. V. Wollaston on the Haltioidae of the Canary Islands. 7 



present Longitarsus is exclusively attached to the fragrant Alesser- 

 schmidtia fruticosa, — on which shrub, when carefully examined, I 

 have scarcely ever failed to detect it. Its range is consequently 

 somewhat lower than that of the L. persimilis, which feeds on the 

 Echia of more lofty elevations. I have taken it abundantly in the 

 waste grounds above the Puerto of Orotava, as well as between Ycod 

 de los Vinhos and Garachico, of Teneriffe ; on rocks between the 

 plains of los Llanos and the Pinal, in the Banda, of Palma ; and a 

 little above the sea- coast, in the district of El Golfo, to the west of 

 Hierro.

 Chrysomela ochroleuca, Mshm., Ent. Brit. 202 (1802). 

 Haltica ochroleuca, Civil., Ins. Suec. iv. App. 658 (1827). 

 Thyamis ochroleuca, Stepb., 111. Brit. Ent. iv. 311 (1831).

 Habitat in insulis Canaria et Tenerift'a, rarior. 



The common European L. ochroleucus appears to be somewhat 

 scarce, or at any rate extremely local, in the Canaries, and may 

 perhaps have been introduced into the islands. I have taken it 

 sparingly near Santa Cruz in Teneriffe ; and, more abundantly, in 

 Grand Canary, where, during April 1858, it was rather plentiful on 

 the mountain-slopes above San Martao, on the ascent to the Roca 

 del Soucilho. 



8. Longitarsus cognatus, n. sp. 

 L. subovatus convexus nitidus testaceus, capito ferrugineo ; prothorace 

 brevi transverso angulis posticis subrectis, vix punctulato; elytris 

 minute et hevissime punctulatis ; antennis gracilibus, ad basin pedi- 

 busque anterioribus pallido-testaceis ; femoribus posticis (praesertirn 

 versus apicem) nigro-piceis, tibiis posticis piceo-testaceis. 

 Long. corp. lin. 1|.

Habitat in ins. Fuerteventura, prope Puerto de Cabras a Dom. Gray 

 Januario exeunte a.d. 1858 repertus. 



The single specimen, from which I have drawn out the above 

 description, was detected by John Gray, Esq., near Port Cabras, in 

 the island of Fuerteventura, during our sojourn there, in his yacht, 

 at the end of January 1858. It is a good deal allied, at first sight, 

 to the common European L. tabidus, but is smaller and of a more 

 pallid hue, and with its hind femora dark. Its antenna? also are 

 slenderer ; its prothorax shorter, more truncated in front, and less 

 margined at the edges ; and its punctuation is altogether very much 

 finer.
