From out of a large number of the T. canariensis, collected through- 

 out the archipelago, I find three specimens, captured in Lanzarote, 

 which difier very considerably from the remainder ; and from these 

 the above diagnosis has been compiled. Nor can I believe them to 

 be any local phasis of that insect, since I have taken the T. cana- 

 riensis (in its most typical state) in Lanzarote also, and therefore 

 exposed to the same external influences as the vestitus. The cha- 

 racters which distinguish the latter are its stronger punctation 

 (which is very evident when viewed under a high magnifying power) 

 and less shining surface, its just perceptibly smaller and relatively 

 narrower outline, and (more especially) the long, coarse, decumbent 

 fulvescent pile with which it is sparingly clothed. Its prothorax, 

 also, is a trifle more constricted at its extreme base ; and its elytra 

 are rather more uneven (or longitudinally subplicate) towards either 

 shoulder, and have just traceable indications, beneath the microscope, 

 of being terminated by a minute basal line — behind the central (ob- 

 solete) portion of which the scutellary region is more sloping, or ob- 

 liquely-depressed. 



My three specimens of the T. vestitus were captured, from be- 

 neath stones, in the submaritime district adjoining the coast-road 

 between Haria and Barranquillo, in the north-east of Lanzarote, on 

 the 15th of March 1859.

 Group, is almost certainly umve):sal in these islands, — though hitherto
