Mr. T. V. Wollaston on Additions to Madeiran Coleoptera. 103 



Monotomas hitherto detected, and rather more parallel in out- 

 line ; piceous, and slightly shining. Head and prothorax lightly 

 punctured, the punctures being small and with a tendency to be 

 disposed in clusters (of twos and threes) : the former with the 

 eyes situated near the base, and with the hinder rim narrow and 

 prominent ; the latter with the sides a good deal straightened, 

 and with the anterior angles produced into a very short but 

 thickened and obtuse spine, and with the two basal fovea? rather 

 distinct. Elytra hardly (if at all) diluted in colouring at the 

 base, and finely seriate-punctate. Limbs rufo-testaceous. 



Two specimens of the European M. longicollis were captured 

 at S. Antonio da Serra (in Madeira proper) by Mr. Bewicke, 

 during the summer of 1859. This gives us no less than five 

 Monotomas for the island-fauna, viz. the spinicollis, Aube, con- 

 gener, Woll., quadricollis, Aube, 4-foveolata, Aube, and longi- 

 collis, Gyll. ; and I may here mention that M. Aube, to whom I 

 lately transmitted an example of my 31. congener for inspection, 

 was scarcely able to detect sufficient differences in it to warrant 

 its separation (in his opinion) fiom the common M. picipes, to 

 which it certainly approaches very closely. It is possible, there- 

 fore, that it may be but a phasis of that insect, in which case the 

 whole five species will be ordinary European ones. Nevertheless, 

 having no longer in my possession the original types of the M. 

 congener, from which I drew up my diagnosis, in 1857, I cannot 

 now re-examine them, and so will not at present venture to 

 amalgamate them with their more northern ally.
