4 Mr. T. V. WoUaston on the Halticidae of the Canary Islands. 



questionably new, though slightly akin to his Aphthona Jlaviceps, — 

 which, however, is smaller, with its prothorax and antennae shorter, 

 and the feet of its males less expanded, (fee. It is apparently rare ; 

 nevertheless I have taken it sparingly at the Agua Mansa, in Tene- 

 riffe ; and from off plants (I think chiefly Semperviva) growing on 

 the damp rocks in the deep sylvan ravines of Palma, — especially the 

 Barranco da Agua, towards the north-east of the island.

4. Longitarsus Kleiniiperda, n. sp. 



L. oblongo-ovatus subnitidus pallido-testaceus, capita vix rufescentiore, 

 prothorace antice angustiore angulis posticis obtusis, elytris sat profunde 

 punctatis, antennarum articulis tribus basalibus testaceis, reliquis plus 

 minus subito nigris, pedibus fere concoloribus (femoribus posticis vix 

 obscurioribus).

The prima facie distinctions (apart fi'om generic ones) between 

 the present insect and the last one have been already pointed out. 

 It is much allied, at first sight, to the common L. tahklus of more 

 northern latitudes ; nevertheless it is less convex and more strongly 

 punctured than that species, its prothorax is less abbreviated and 

 rather more narrowed in front, its antennae and legs are longer, and 

 the basal joint of the fom- front male feet is altogether larger, and 

 broader. Its habits, too, are quite different, since it appears to be 

 almost entirely attached to the leaves of the Kleinia neriifolia, on 

 which it often exists by thousands, and whole plants of which I have 

 occasionally obsei-ved almost defoliated by its attacks. In such posi- 

 tions I have taken it abundantly in the waste grounds above the 

 Puerto of Orotava, and near Santa Cruz, as also in the sylvan 

 districts of the Agua Garcia and Taganana, of Teneriffe ; in the 

 Barranco above Santa Cruz, of Palma ; and toAvards the coast, in 

 El Golfo, of Hierro.
