8 CANARIAN COLEOPTEEA. 



of Morocco) appears to be very rare at the Canaries,— where it was 

 found by Mr. Gray and myself, during January 1858, near Arrecife 

 in Lanzarote : and subsequently, by myself, in the little island of 

 Graciosa, off the north of Lanzarote ; as well as at the extreme south- 

 ern, sandy point of Grand Canary, in the district of Maspalomas. 

 It was likewise captured in Lanzarote by M. Hartung.

The comparatively large size and more piceous hue of this fine 

 Dyschirius, in conjunction with its tridentate clypcus and the greatly 

 developed spines of its fore tibite, will at once distinguish it from the 

 following two species. It has been examined by my friend Dr. 

 Schaum, of Berlin, who has paid much attention to the genus, and 

 Avho returned it with the observation : " It is probably allied to the 

 D. falvipes, Dej. (unknoAvn to me) ; but in that insect the marginal 



and have but little doubt that it was brought from Madeira by Mr. Webb (along 

 with the Hmyalus consenfanens and distinguendus, and possibly also the Lionis 

 angustatus), and mixed-up by him with liis Canarian collection. I have the 

 most positive assurance from a personal friend of Mr. Webb, that the latter col- 

 lected in Madeira before he went to Teneriife, and that he was exceedingly care- 

 less and inaccm-ate with respect to the material which he was in the habit of 

 amassing : — a fact indeed which is proved to a demonstration tlu'ough the cir- 

 cumstance of one of his Land-Shells (an Achafma) having been described by 

 D'Orbigny (in MM. Webb and Berthelot's work) as a new Canarian species, but 

 which 011 reference to the type may be seen to have in Mr. Webb's own hand- 

 writing a label attached to it bearing the words '• Pico de Facho," — which Pico 

 de Facho (as the shell itseh'' would in fact testify) is one of the mountains of Porto 

 Santo (an island in which Mr. Webb sojourned during May of 1828) ! ! Now it 

 so happens that the only character of any significance which M. Brulle alludes 

 to in his (so-called) description of the 6'. dimidiatus is to the etfect that its elytral 

 stria' are punctured. In the ahltreriatus the stria; are usually impunctate ; never- 

 theless they have sometimes a tendency to be very faintly pimctured even in Ma- 

 deira proper and on tine Desertas. but in Porto Santo they are nearly always very 

 perceptibly punctate. So that I conclude, first, that M. Brulle's »S'. dimidiatus 

 is founded upon an example (since lost — for it does not now exist in the collec- 

 tion at the Jardin des Plantes, in Paris) of the ahhrcviatifs brought by Mr. Webb 

 from Madeira ; and secondly, that the specimen was, like the Land-Shell above 

 referred to, a Porto-Santan one.
