CURCULIONID^E. 



or small, and with its sexual peculiarities (which consist in the 

 scooping-out of the anterior tibiae, and the serrations of the hinder 

 pair) more or less expressed. Amongst the many phases thus assumed, 

 I have tried hard to find the indications of a second species ; but 

 after a careful comparison of individuals from many different loca- 

 lities and altitudes, it appears to me that the several states above 

 alluded to pass so completely into each other that it is quite impos- 

 sible to treat any of them as of specific importance. In a general 

 sense, however, those examples in which the surface is duller, and in 

 which the interstitial punctures are more minute and the tibiae of 

 the males less excavated (or, in other words, in which the essential 

 characteristics of the species are less pronounced), may be regarded 

 as falling under the " var. /3. lugubris " of my diagnosis. 



Three Gomeran individuals which are now before me are such 

 thorough exponents of this last-mentioned state that, if taken alone, 

 they might well be cited as specifically distinct ; but when examined 

 in conjunction with others from Teneriffe, I am satisfied that they 

 have no claim whatever for separation. Of the Teneriffan examples, 

 those from the laurel- woods on the mountains towards the north- 

 east of the island (in the direction of Las Mercedes, Taganana, and 

 Point Anaga) seem to have their specific features most exaggerated ; 

 whilst those from the Agua Garcia, and above Ycod el Alto, are 

 appreciably somewhat more on the Gomeran (or "var. (3. lugubris") 

 type.

Pound under similar circumstances, and in the same district at 

 Teneriffe, as the last species the only two examples which I have 

 seen having been captured by myself on the laurel-clad mountains 

 above Taganana.

Likewise found in the sylvan districts of intermediate elevations in 

 Teneriffe, and a species of which I have captured but few examples. 

 Further material, therefore, is much wanted, in order to complete
