tion to the Cryptojyhagi, assures me that he is not aware of 

 any species upon record with which it can be made to agree. 

 Apart from its rather small size, convex body, and dark rufo- 

 ferruginous hue, its most distinctive features consist in its 

 extremely coarsely and densely punctured surface, which is 

 beset all over (though especially on the elytra) with very 

 elongate and nearly erect, soft, whitish hairs. Its limbs, too, 

 are marvellously slender — even more so, perhaps, than is the 

 case in the particular section of the group (represented by the 

 C. vini in Europe, and G. hesperius in the Canarian archi- 

 pelago) to which it belongs. Its incrassated anterior protho- 

 racic angle is rather largely developed, with the hinder point 

 of it more or less acute ; but there seems to be no central 

 lateral denticle, the sides being merely minutely crenulated — 

 so minutely, indeed, as sometimes to appear nearly simple. 



Fam. Elateridae. 



Genus ANCHAgTUS. 



Leconte, Trans. Am. Phil. Soc. x. 459 (1853). 



Anchastus atlanttcus. 



Anchastus atlanfiats, Cand., Mon. Elat. ii. 409, t, 3. f. 8 (1859). 

 Heteroderes 2}uticticollis, Woll., Ann. Nat. Hist. iv. 317 (1869). 



It would a])pear that the Elaterid which I described two 

 years ago under the name of ^^ Heteroderes jpuncticollis " is the 

 Anchastus atlanttcus of Cand^ze's Monograph ; so that the 

 above correction in its synonymy becomes necessary. Mr. 

 Janson informs me that its general fades is almost exactly 

 that of a Heteroderes^ and it is not surprising, therefore, that 

 I should have referred it to that group ; and he further adds 

 that it is totally unlike any Anchastus with which he is 

 acquainted. 



Fam. CurculionidsB. 



(Subfam. COSSONIDES.) 

 Genus MiCROXYLOBIUS. 



Chevrolat, Trans. Ent. Soc. Lond. i. 98 (1836). 



Of this interesting little Cossonideous group three additional 

 exponents have been brought to light, through the careful 

 researches of Mr. Melliss, since my enumeration of the St.- 

 Helena Coleoptera two years ago. They all of them belong 

 to the first section of the genus, regarded by me as the typical 

 one, in which the femora are totally unarmed ; and one of 

 them (the M. cossonoides) is so large compared with the re- 

 mainder, and so dissimilar in the elongation of its rostrum and
