Coleoptera of the Canary Islands, 143 



one of which is pecub'ar to the pine-trees and the other to tlie 

 laurels. If therefore the individual from which my diagnosis has 

 been compiled may be regarded as normal, the L. caulicola may 

 be known at once from its allies by its smaller size, paler hue, 

 and its more transversely-rugulose elytra ; whilst its totally dif- 

 ferent habits will still further characterize it. In the sculpture of 

 its very parallel elytra, however, it has more in common with the 

 L. laurkola than with the other ; nevertheless its densely punc- 

 tured head and prothorax and but slightly alutaceous surface are 

 more suggestive of the L. phiicola : but in the thickness of its 

 prothoracic margin it is about intermediate between the two. 



Genus Trogosita. 

 Olivier, Ent. ii. 19 (1790). 

 2. Trogosita latens* n. sp. 



T. subdepressa, nigra, subopaca ; capite prothoraceque remote 

 punctatis (punctis in disco minutis), hoc transverso-sub- 

 quadrato antice latiusculo, angulis anticis vix productis, ad 

 latera subrotundato ; elytris subparallelis, profunde punctato- 



head and prothorax being rather less closely and not quite so coarsely punctured, 

 and by the marginal rim of the latter (as well as that of the elytra) being much 

 thicker or defined. Its anterior prothoracic angles, too, are a trifle less obtuse, 

 and with the margin at that particular point very much more developed or incras- 

 sated. 



Leipaspis pinicola, n. sp. 

 L. subviridi- vel etiam subcyaneo-picea, nitida, minus alutacea ; capite pro- 

 thoraceque dense et profunde punctatis, hoc angustissime marginato angulis 

 anticis valde obtusis ; elytris subparallelis (versus humeros subangustiori- 

 bus), angustissime marginatis, profunde crenato-strialis et distincte trans- 

 versim rugulosis; antennis, palpis pedibusque laete rufo-ferrugineis. 

 Long. Corp. lin. 85 — 4. 



Habitat in pinetis Teneriffas et Palmae, sub cortice laxo Pint canariensis 

 rarissima. 



Known from the last species (as has been already implied) by its elytra being 

 rather more contracted, or drawn-in, at their base (and therefore a trifle more 

 widened behind the middle), as well as a little more transversely-rugulose and 

 more deeply crenate-striated. The lateral rim, too, both of its prothorax and elytra 

 is very much less developed, its surface is somewhat more shining, less coarsely 

 alutaceous, and of a more piceous tinge, and the punctuation of its head and pro- 

 notum is perceptibly deeper and more dense. Its anterior prothoracic angles are 

 rather more obtuse and very much less margined. So far as I have observed hi- 

 therto, it is found exclusively beneath the loose bark of the Pinus canarieitsU,— 

 in which positions I have captured it at the Agua Mansa, and above Ycod de los 

 Vinhos, of Teneriffe, as also in the old Pinal adjoining the Caldeira in the 

 Banda of Palma.
