APPENDIX. 49 



tiore, depressiore, pallidiore, et minus opaco ; rostro vix subgraci- 

 liore ; prothorace sensim breviore, integro (i. e. nullo modo pone 

 apicem subconstricto) ; elytris paultilum minus ovatis, per margi- 

 nem basalem ne subincrassatis quidem, et setulis paulo longioribus 

 (tamen brevissimis, minutissimis) longitudinaliter obsitis ; pedibus 

 subbrevioribus ; antennarum capitulo paulo minus abrupto et 

 magis breviter ovato (minus ovali). 



Two examples of this interesting little blind Curculionid were 

 taken by the Messrs. Crotch, during their late Canarian expedition, 

 at a high altitude on the mountains of Gomera, from beneath 

 rotten wood, in the laurel-district above Hermigua. They are so 

 nearly allied to my unique T. ccecum, which I captured (in 1858) 

 under the trunk of a felled cherry-tree at the bottom of the Curral 

 das Freiras in Madeira that I cannot feel entirely satisfied that they 

 are more than the exponents of a geographical state of the same 

 species a point which can only be decided by a critical examination 

 of further material from both Groups. Until, however, additional 

 evidence has been obtained, I think it would be extremely rash to 

 treat the combination of minute differences which the two Canarian 

 individuals present (when compared with the Madeiran one) as 

 absolutely indicative of no more than a local, or insular, phasis of 

 the T. ccecum. 



Regarding therefore the individuals now before me as typical of 

 the two species, the T. orbatum appears to be a trifle smaller, nar- 

 rower, paler, more depressed, and less opake than the ccecum ; its 

 rostrum is just perceptibly slenderer; its prothorax is appreciably 

 shorter, and free from even the faintest rudiment of the transverse 

 constriction behind the apex, which seems to be (as in Acalles} more 

 or less evident in the T. ccecum; its elytra are a trifle less ovate, 

 with their extreme basal margin not in the least degree thickened, 

 and with the diminutive setae, or abbreviated hairs, with which 

 they are longitudinally studded, (although thus short and minute) 

 decidedly longer than is the case in that insect ; its legs are perhaps 

 somewhat less developed ; and its antennal club is more obovate (or 

 less oval), and not quite so abrupt.
