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



accordingly ; nevertheless, if it should prove hereafter to be di- 

 stinct from that insect, I would propose for it the trivial name 

 of falcatus — in allusion to its narrow and sickle-shaped mandi- 

 bles, which (inter alia) immediately distinguish its male sex from 

 the corresponding one of its ally. It would seem that the female 

 is the scarcer sex of the two ; for out of the twenty-one exam- 

 ples from which the above description has been compiled, seven 

 are females and fourteen males. And, indeed, the same appears 

 to obtain in the G. cornutus also, since, of eleven Madeiran exam- 

 ples now before me, three only are females. 



Fam. Opatridae. 



Genus Hadrus.

Hadrus Paivce, n. sp. 



H. oblongus, niger, subtiliter et crebre granulatus ; elytris substriatis, 



levissime et subtilissime pubescentibus.

H. oblong (being of almost the same outline as the H. alpinus), 

 black, almost free from scales, and rather more coarsely, and 

 less closely, granulated all over than the H. alpinus, but not near 

 so coarsely as the cinerascens. Head with the clypeus expanded 

 into a lateral angle in front of the eyes, as in the latter species, 

 instead of being rounded-ofT, as in the former one. Prothorax 

 of the same shape as that of the cinerascens, being a trifle more 

 expanded anteriorly than in the alpinus, and not quite so broadly 

 flattened at the sides. Elytra very obsoletely striated, but rather 

 more perceptibly so than in the alpinus, and, under a high 

 magnifying power, beset with an excessively short, minute, and 

 distant fulvescent pile. Antenna and tarsi obscurely piceous. 



As will be perceived from the above description, the present 

 Hadrus is intermediate in its features between the H alpinus and 

 cinerascens (though remarkably distinct, and never merging into 

 either of them) — combining the general outline of the former 

 with the angulated clypeus of the latter; whilst in the relative 

 coarseness of its sculpture (though not in its precise character) it 

 is about midway between the two. In the pubescence of its 

 elytra, also, which is very delicate and obscure, it is intermediate 

 between the totally unclothed H. alpinus and the rather more 

 evidently (though very minutely) setulose and roughened surface 

 of the H. cinerascens. It was detected by myself, on the 18th of
