CANARIAN COLEOPTEPvA. 17 



belong to the same type as the European M. foveola ; and are still 

 more nearly akin to the 31. foveolatus, Dej. (cupreiis, Waltl), found 

 in the south of Spain and at Tangiers, and which I have myself taken 

 in the sandy district at Mogadore, on the west coast of Morocco. 

 Nevertheless from the latter they may, both of them, be immediately 

 known by their entirely wanting the paler humeral patch which is 

 always more or less evident in that insect. Touching their differences 

 inter se, Dr. Schaum remarks : " The species from Palma and Tene- 

 riffe [i. e. incequalis] I consider certainly new ; the one from Lanza- 

 rote [lancerotensis] seems to me to be a second species, and no local 

 state of the other. The Palman specimens not only have more un- 

 even, and more distinctly stiiated, elytra, but also larger fovece both 

 on the disk and in the lateral series ; whilst the Lanzarotan ones are 

 more shining and almost free from striae. From foveola the Palman 

 species is distinguished by its uneven elytra and large fovese (both 

 discal and at the sides) : the Lanzarotan species, on the other hand, 

 has the small foveae of foveola, but its elytra are almost smooth and 

 brilliant (whereas in foveola they are opake and finely striated)." 



I have observed the M. incequalis hitherto only in the islands of 

 Grand Canary, Teneriffe, and Palma ; but it has recently been cap- 

 tured by Dr. Crotch in Gomera also. The Palman examples have 

 perhaps, on the whole, the distinctive characters of the species best 

 expressed, their elytra being always exceedingly uneven and their 

 discal impressions very large. Those from Teneriffe can scarcely be 

 regarded as in reality less t}q3ical, though occasionally they may 

 appear just perceptibly smoother. But the only three which I have 

 as yet captured in Grand Canary (during my sojourn at El Monte, in 

 March 1858), although quite as conspicuously striated as those from 

 Teneriffe and Palma, have their fovese less developed. It is eminently 

 a sylvan insect, the few specimens which I have observed in compa- 

 ratively open spots being probably the remains of a fauna which has 

 more or less died -out since the timber has been destroyed. In Palma 

 it abounds in most of the wooded ravines, such as the Barranco d:i 

 Agua, the Barranco de Galga, &c. ; whilst in Teneriffe I have cap- 

 tured it above Taganana, at Las Mercedes, La Espcranza, the Agua 

 Garcia, Souzal, the Agua Mansa, Ycod el Alto, and even on the 

 Cumbre adjoining the Canadas (upwards of 8000 feet above the sea).
