Mr. T. V. Wollaston on Additions to Madeiran Coleoptera. 253 



the Tarphii generally. Elytra concolorous, rounded and convex, 

 deeply seriate-punctate, and without transverse wrinkles, the 

 punctures being large, regular, and distinct.; the alternate inter- 

 stices a little raised and much interrupted, forming small but 

 very conspicuous nodules in the usual positions, which are more 

 or less clothed with yellowish, or golden, setse. Femora and 

 tibia blackish-piceous ; the tarsi and antennae (the latter of which 

 have their club, especially the apical joint, a little larger and 

 more abrupt than in the generality of the Tarphii) piceo-ferru- 

 ginous. 



Eight specimens of the present very distinct Tarphius were 

 captured by Mr. Bewicke in Madeira proper, in the upland 

 region of the Fanal (more than 4000 feet above the sea), during 

 the summer of 1859. Although with many characters which 

 belong to neither of them, it is in some respects intermediate be- 

 tween the T.sylvicola and Lauri, combining the dark hue, rounded 

 elytra, and deep sculpture of the former, with the posteriorly 

 constricted (but altogether narrower, and otherwise different) 

 prothorax of the latter. Nevertheless, in its very distinct 

 nodules (which are more or less sparingly clothed with golden 

 seta?), and its rather larger antennal club, it recedes, inter alia, 

 from them both. I have adopted the above trivial name in allu- 

 sion to the general narrowness of its prothorax. 



Genus AGLENUS. 

 Erichson, Nat. der Ins. Deutsch. iii. 285 (1848). 



The genera Aglenus and Anommatus are both of them addi- 

 tions to the Madeiran fauna; and in their small, glabrous, 

 shining bodies, and obsolete eyes, as well as in their general 

 aspect and habits, they have much in common. Still I believe, 

 in reality, with M. Jacquelin Duval (vide Gen. des Col. d'Europe, 

 ii. 242), that, in spite of their resemblance to a certain extent, 

 they belong to distinct families ; and hence I would record the 

 former of them only as a member of the Colydiada. Apart from 

 their specific differences, which are very conspicuous, Aglenus 

 may be known from Anommatus by, inter alia, its distinctly 

 11 -jointed antennae, with their loosely-connected triarticulate 

 club, by its slenderer limbs, and its evidently tetramerous feet. 

 They are both of them found beneath vegetable substances, 

 Aglenus, however, preferring comparatively dry refuse, like that 

 which accumulates round the edges of hay- and corn-stacks (to 

 which it is much attached), and sometimes occurring even beneath 

 bones ; whilst Anommatus is more commonly found under logs 

 of moist rotting timber on the damp ground.
