selves, suffice equally to separate it. It may, therefore, be 

 regarded as a small generic group in all probability peculiar to 

 the Canarian archipelago. 



1. Leipcispis caullcola* n. sp. (PI. VII. fig. 1.) 



L. subviridi-ferruginea, nitida, subalutacea^ capita protho- 

 raceque dense et profunde punctatis, hoc anguste marginato 

 angulis anticis obtusis ; elytris parallelis, distincte marginatis, 

 crenato-striatis et valde transversim rugulosis ; antennis, 

 palpis pedibusque rufo-testaceis.

Habitat Teneriffara, in Euph. canariensi putrida in montibus 

 supra Sanctam Crucem detecta. 



Of the present Leipaspis I have seen hitherto but a single ex- 

 ponent ; and as I am not certain whether it is perfectly mature, 

 I am doubtful whether the colour of the species may not in reality 

 be somewhat darker than is the case in the specimen now before 

 me: whilst its small dimensions, as compared with those of two 

 nearly related Canarian forms, may possibly be, to a certain 

 extent, merely accidental. Re this, however, as it may, the 

 L. caullcola cannot be safely referred, I think, to either of its 

 allies, though it must be admitted that the whole three are inti- 

 mately connected. The fact, moreover, of my having found it 

 within the putrid stem of a Euph. cananensis (on the mountains 

 above Santa Cruz of TenerifFe) would go far to render it d priori 

 probable that the species is truly distinct from the other two,"]" — 



t I subjoin the following diagnoses of these two species, which will serve lo 

 point out their distinctions from the L.' caullcola. 



Leipaspis lauricola, n.sp. 

 L. viridi-picea, subnitida, distincte alutacea; capite piothoraceque sat dense 

 punctatis, hoc crasse marginato angulis anticis obtusis ; elytris parailelis, 

 distincte marginatis, crenato-striatis et plus minus obscure transversim rugu- 

 losis; antennis, palpis pedibusque iagte rufo-ferrugineis.

Habitat sub cortice laurorura laxo in locis editioribus sylvaticis Teneriffas et 

 Palmse, rarior. 



Apparently quite peculiar to the laurels of intermediate and rather lofty eleva- 

 tions, — beneath the loose outer bark of which 1 have taken it in the woods above 

 Taganana, and towards Point Anaga, of TenerifFe, as also in the Barranco de 

 Galga and the Barranco da Agua on the east of Palma. It is extremely variable 

 in size ; nevertheless it may always be known from its near ally the L. pinicola 

 by having its elytra more decidedly parallel and less deeply crenate striated, by its 

 surface being rather greener and more evidently alutaceous and subopake, by its
