Mr, T. V. WoUastoii on the Halticidae of the Cananj Islanrls. 3 



Variat (feneo-cuprea) pedibus iu utroque sexu omnino pallidis. 



Habitat in foliis Euphorbiarum (prfesertiin E. piscatorice et Regis Jiibce) 

 iu ins. Lanzarota, Canaria, Tenerifta et HieiTO, valde gi-egaria. Viro 

 illustrissimo Baronis ei lusitanice " Castello de Paiva " dicato banc 

 Halticam formcsam certe novam, ob gratias mihi amicissime oblatas, 

 ti'ibui. 



A metallic species of very variable coloui", 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 Juhce by Mr. Gray and myself on the 

 cliflfe above the Salinas, in the north of Lanzarote, duiing January 

 1858 (in which same locality I captiu'ed 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. cylindi'ico-ovata nitida subliyalina testacea, capite paiilo riifescentiore, 

 prothorace transverso-subquadrato angidis ipsis posticis leviter promi- 

 nulis acutiusculis, elj^tris paulo pallidioribus leviter subtilissime punc- 

 tidatis, antennarum articulis 4 basalibus rufo-testaceis, reliquis paulatim 

 nigi-escentibus, pedibus plus minus rufo-, femoribus antei'ioribus pal- 

 lido-testaceis. 



Long. Corp. lin. 2|-2f . 



Mas, antennis idx longioribus robustioribus ; tarsis anterioribus articido 

 basilar! valde dilatato [secundo latiore]. 



Habitat in foliis plantarum ad rapes locormii editiorum crescentiimi, 

 prsesertim Sempertnvi, 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 quadi'ate prothorax, stouter antennae (which 

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

 testaceous), and by its more finely punctured elj-tra. 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. artssipes is peculiarly 

 conspicuous. I am informed b}' M. Allard, of Paris, that it is un-
