TROGOSITIDJE. 115 



be found to occur wherever the remains of those ancient pine-forests 

 still exist. Nevertheless it is extremely rare, or at any rate local, 

 even in those particular regions. I have myself taken it in Grand 

 Canary and Palma ; and it was captured by the Messrs. Crotch during 

 the past summer in Teneriffe and Hierro. Its presence in Hierro is 

 most interesting ; for the Final itself (in its now reduced dimensions) 

 occupies but a small and elevated area at the southern end of the 

 Cumbre, or backbone, of that remote island. 



Genus 105. LIPASPIS. 

 Wollaston, Trans. Ent. Soc. Lond. 140 [script. Leipaspis] (1862). 



323. Lipaspis lauricola. 



Leipaspis lauricola, Woll., loc. cit. 143 (1862). 

 Lipaspis lauricola, Id., Cat. Can. Col. 120 (1864). 



Habitat Canarienses (Ten., Gom., Palma, Hierro), sub cortice arbo- 

 rum laxo pnesertim in lauretis humidis editioribus latens. 



A Canarian insect, attached normally to the damp laurel-regions 

 of a high altitude where it occurs beneath dead, loosened bark. 

 Occasionally, however, it will attack other trees; for the Messrs. Crotch 

 report its capture (in a few instances), both in Gomera and Hierro, 

 in fig- trees ; but I think it is not unlikely that such specimens may ' 

 have been brought down accidentally from the laurel-forests amongst 

 bundles of fire-wood, and may have adapted themselves subsequently 

 (as they were best able) to the altered circumstances and a lower 

 range. In Teneriffe and Palma I have met with it in tolerable 

 abundance ; whilst in Gomera and Hierro it has been taken by the 

 Messrs. Crotch. 



324. Lipaspis pinicola. 



Leipaspis pinicola, Woll., loc. cit. 143 (1862). 

 Lipaspis pinicola, Id., Cat. Can. Col. 120 (1864). 



Habitat Canarienses (Ten., Palma), in pinetis rarissima. 



Hitherto I have observed this (likewise Canarian) Lipaspis only 

 in Teneriffe and Palma, where it occurs (though very rarely) beneath 

 the dead bark of pines at rather lofty elevations. The discovery by 

 the Messrs. Crotch of the L. lauricola in fig-trees renders it just 

 possible that the pinicola may be some form of that species peculiar 

 to the Pinals, for certainly its distinctions are not very conspicuous 

 ones. Nevertheless I do not believe that such is probable ; though, 

 from the very few examples of the pinicola which I have yet seen,
