10 Mr. T. V. Wollaston on the Halticidae of the Canary Islands. 



where I have taken it abundantly around the wood at the Agua 

 Garcia; and it was captured by Mr. Gray in the valley of San 

 Sebastian in Gomera, and near S'* Cruz in Palma. It is identical 

 with the species which I described, from the Madeiran Group, in 

 1857, under the name of L. excurvus, from specimens detected in 

 Porto Santa by Mx. Bewicke. 



Genus Pstlliodes. 

 LatreiUe, Fam. Nat. des Ins. 405 [script. Psylliode] (1825). 



15. Psylliodes hospes, WoU. 



Psylliodes hospes, WolL, Ins. Mad. 449 (1854). 

 , WoU., Cat. Mad. Col. 134 (1857). 



Habitat insulas Canarienses, preesertim in locis inferioribus frequens. 



The P. hospes abounds at low and intermediate elevations through- 

 out the Canarian Group, on the whole seven islands of which I have 

 taken it in greater or less profusion ; and it was also captured in 

 Lanzarote, Gomera, and Hierro by Mr. Gray. In the Madeiras also, 

 though less common, it is nearly (if not quite) universal, having been 

 observed by myself in Madeira proper, in Porto Santo, and on the 

 Dezerta Grande ; so that it may be properly regarded as an Atlantic 

 species. It is the representative of the P. cuprea of more northern 

 latitudes ; and M. Allard, to whose examination I have lately sub- 

 mitted it, retiirned it with the remark : " Psyll. cuprece, lU., aflinis, 

 et ut ilia in elytris punctate -striata, sed differt interstitiis punctu- 

 latis, prothorace ad latera minus recto, et cset." 



16. Psylliodes vehemens, Well. 



Psylliodes vehemens, WoU., Ins. Mad. 451 (1854). 

 , WoU., Cat. Mad. Col. 134 (1857). 



Habitat insulas Canarienses, tempore vernali et sestivo, ubique vulgaris. 



Like the last species, the present one abounds throughout the 

 Canarian archipelago, Gomera being the only island on which I have 

 not hitherto captured it ; nevertheless there can be no doubt that it 

 exists there, no less than on the others, — our short visit to that 

 island happening to be during the depth of winter, when the Halti- 

 cidce are not plentiful. It was taken also by MJr. Gray in Fuerte- 

 ventvira and Palma. It is equally common Hkewise in the neigh- 

 bouring group, where I have observed it, in profusion, at nearly all 

 elevations in Madeira proper, as well as in Porto Santo and on the 

 Dezerta Grande.
