Mr. T. V. Wollaston on the Halticidae oj the Canary Islands. 3 



Varied (aeneo-cuprea) pedibus in utroque sexu omnino pallidis. 



Habitat in foliis Euphorbiarum (praesertim E. piscatorice et Regis Jubce) 

 in ins. Lanzarota, Canaria, TenerifFa et Hierro, valde gregaria. Viro 

 illustrissimo Baronis ei lusitanice (t Castello de Paiva " dicato banc 

 Halticam formosam certe novam, ob gratias raibi aniicissime oblatas, 

 tribui. 



A metallic species of very variable colour, shading off from bright 

 cyaneous-blue into golden-green, and almost, at times, into coppery- 

 brown. It is attached to the foliage of the various large Euphorbias, 

 and was taken on the E. Regis Jubce by Mr. Gray and myself on the 

 cliffs above the Salinas, in the north of Lanzarote, during January 

 1858 (in which same locality I captured it again, abundantly, in 

 March of the following year) ; as also, by myself, on the mountains 

 above San Martao, in Grand Canary ; on the E. piscatoria above the 

 Puerto de la Orotava, of Teneriffe ; and in the district of El Golfo, 

 in the west of Hierro. I have dedicated it to my learned and excel- 

 lent friend the Barao do Castello de Paiva, to whose researches, 

 especially in Madeira and Portugal, I have been frequently indebted 

 for many additions to my collection. 



3. Haltica crassipes, n. sp. 



H. cylindrico-ovata nitida subhyalina testacea, capite paido rufescentiore, 

 protborace transverso-subquadrato angulis ipsis posticis leviter promi- 

 nulis acutiusculis, elytris paulo pallidioribns leviter subtilissime punc- 

 tulatis, antennarum articidis 4 basalibus rufo-testaceis, reliquis paulatim 

 nigrescentibus, pedibus plus minus rufo-, femoribus anterioribus pal- 

 lido-testaceis. 



Long. corp. lin. 2^-2f . 



Mas, antennis vix longioribns robustioribus ; tarsis anterioribus articido 

 basilari valde dilatato [secundo latiore]. 



Habitat in foliis plantarum ad rupes locorimi editiorum crescentium, 

 praesertim Sempervivi, in ins. TenerifFa et Palma, rarior. 



At first sight the present insect and the following one are some- 

 what alike ; nevertheless, apart from the generic characters (of the 

 longer legs and hind feet, &c.) of Longitarsus, the H. crassipes may 

 be known by its more quadrate prothorax, stouter antennae (which 

 have four of their basal joints, instead of only three, more or less 

 testaceous), and by its more finely punctured elytra. Its four ante- 

 rior male tarsi have their basal joint greatly dilated, so as far to 

 exceed the second, — a structure which is more or less expressed in 

 most of the Halticidce, but which in the H. crassipes is peculiarly 

 conspicuous. I am informed by M. Allard, of Paris, that it is un-
