that it is the insect referred by him, in M. Hartung's list, to that 

 species. It belongs, however, in reality, to a cliiFerent group.

Habitat TenerifFam, prsesertim in locis subelevatis, rarior. 



The two Canarian Zahri (both of them peculiar to Teneriffe) are 

 very closely related inter se, but I believe triily distinct. The present 

 one is a little more robust and ovate than its ally (being, on the 

 average, a trifle more expanded posteriorly), and rather less shining 

 (or a little more evidently alutaceous) ; its prothorax is just percep- 

 tibly broader, somewhat more strongly impressed behind, and more 

 widely depressed at the sides ; its elytra are veiy much more deeply 

 striated, and its limbs are usually a shade darker. It is certainly 

 the rarer of the two, and foimd for the most part at a rather higher 

 altitude, — though I have taken it occasionally on the hiUs behind 

 S''* Cruz at only a slight elevation above the sea. On the mountains, 

 however, above Taganana, and at Las Mercedes, it appears more 

 within its normal range.

 Habitat Teneriifam, prsecipue in locis subinferioribus, hinc inde 

 vulgaris. 



This appears to be the commoner of the two TenerifFan Zahri, 

 though at the same time somewhat local, I have taken it rather 

 abundantly in the dry cindery region between the Puerto Orotava 

 and the Villa, where it occurs beneath stones during the spring ; and 

 it has also been captured by Dr. Crotch. It may be known from its 

 ally by being, on the average, a little smaller and more oblong (or 

 less dilated behind) ; by its prothorax being more narroivly depressed 

 at the sides (particularly towards the posterior angles), altogether 

 not quite so broad, and with its basal impressions perhaps somewhat 

 lighter ; and by its elytral striae being much less deep, its limbs 

 generally of a paler hue, and its entire surface just perceptibly more 

 shining (or less distinctly alutaceous). I have received it from Dr. 

 Heer (collected by M. Hartung) under the name of " crassus, Dej." ;
