Likewise a European Acrotrichis, and one which occurs (though 

 not very abundantly) in Madeira proper at rather low and inter- 

 mediate altitudes ; but it has not yet been detected in any of the 

 other islands*.

Habitat Maderenses {Mad.}, et Canarienses (Grom.), prsecipue sub

Like the two preceding species, a European Acrotrichis and one 

 which seems to be comparatively rare in these islands where it 

 occurs, for the most part, at rather low elevations. In Madeira 

 proper however I met with it somewhat commonly, under (and 

 within) the dung of cattle, about a mile to the westward of Funchal 

 -towards the Praia Formosa ; and two examples of it were cap- 

 tured by Dr. Crotch in Gomera, during his first trip to the Canaries.

Habitat Canarienses (Ten., Gom.), a "W. D. Crotch A.D. 1862 detecta. 



A small and deep-black Acrotrichis remarkable for its rather 

 short and parallel, or even (at any rate in one sex) somewhat pos- 

 teriorly widened outline, and for the aim ost unproduced hinder angles 

 of its prothorax. It is a Canarian species, several examples of it 

 having been captured by Dr. Crotch (during the spring of 1862) in 

 Teneriife and Gomera. 



Genus 88. NEPHANES. 

 Thomson, Skandin. Coleopt. i. 62 (1859). 



* The A. Montandoni appears to be very nearly allied to the CJievrierii of 

 Allibert ; but Mr. Matthews remarks that in the former the prothoracic granules 

 " are further apart from each other, and the interstices more coarsely alutaceous 

 [or, rather, as it seems to me, reticufose] ; whereas in the Chevrierii they are 

 closer together and more numerous, and the interspaces are finely alutaceous."
