CANARIAN COLEOPTERA. 449 



ad lateraet basin grossemarginatis; anteniiis pedibusque (praeser- 

 tim tarsis) picescentioribus. — Long. corp. lin. 4-7. 



Tentyria (3fcsoste»a) elougata*, Bridle, in Wehh et Berth. (Col.) 66 

 (1838). 



Habitat in arenosis submaritimis Fuerteventurae et Canariae, ad 

 radices plantarum juxta mare ci'escentium latens. 



This large and slender insect, with its greatly elongated limbs, 

 would appear to reside amongst the loose sand which collects into 

 small hillocks by drifting around the roots of shrubby plants, within 

 a short distance of the sea-shore (though not upon the actual beach). 

 In such situations it was taken by Mr. Gray and myself about a mile 

 to the south of Puerto de Cabras in Fuerteventxira during January 

 1858 (in which locality I again met with it in April of the following 

 year) ; and by myself, and subsequently by Dr. Crotch, on the low 

 sand-hills of Grand Canary between Las Palmas and the Isleta. The 

 Grand-Canarian specimens are, on the average, larger than the 

 Fuerteventuran ones. 



Genus 261. PAIV^A (nov. gen.). 



Instrumenta cibaria fere ut in Tentyria, sed corpus alitor constructj,im 

 pilisque elongatis erectis obsitum ; ejyistomate ad apicem acute an- 

 gulato-producto ; antennarxmi articulo ultimo penultimo minore, 

 oblique truncato ; prothorace antice latiore, basi bisinuato, angulis 

 posticis vix subrectis, argute determinatis ; scutello multo breviore, 

 sc. brcvissimo, transverso, costiformi ; elytris ad basin grossius 

 marginatis, ad humeros magis angalatis ; antenuis pedibusqae ro- 

 bustis, pilosis.

Although the oral organs of nearly the whole of these immediate 

 groups are almost similar, there can be little doubt, I think, that 



* M. BruUe cites this species as a membei' of (what he would appear to regard 

 as, thougli very erroneously, the st(bgeniis) Mcsosfena. It has, however (judging 

 from the diagnosis), nothing whatever to do with that group — though, superfici- 

 ally, it certainly possesses the comparatively slender body of the Mesosfencs. But 

 the form of the eyes and the greatly elongated tliird joint of its antennae (even 

 inore. so, perhaps, than in the true TentyricE) entirely remove it from Mcsostena ; 

 whilst from Axumia it is as readily separated by its last antennal joint being as 

 broad as the penultimate one, as well as by its perfectly distinct scutellum and 

 its convex body. Nevertheless it is by no means a very normal Tentyria, and 

 may perhaps constitute the type of a closely allied genus — its much narrower 

 and slenderer outline and more deeply punctui'ed surface, in combination with 

 its larger and more prominent eyes (which are regularly reniform, and therefore 

 but slightly contracted in their lower half), the more defined posterior angles of 

 its prothorax, and its very much longer and thinner limbs and claws, all tending 

 to remove it from the ordinary representatives of that group.
