fourth row with a rounded humeral one, and four small tubercles 

 or granules, tubercles wanting beyond level of commencement of 

 third row. Sides smooth, with obsolete punctures. Beneath set 

 with minute, setigerous granules; apical segment with a slight 

 impression at apex. Anterior tibiae without denticles. 



9- Larger, more obese; head, rostrum, and protborax similar. 

 Clothing rather denser. Elytra (14x9 mm.) more convex, 

 strongly ampliate, tubercles more numerous, smaller, rounded, at 

 most subconical; first row of five increasing in size from near base 

 to declivity, and two decreasing in size on declivity; second with 

 eight, rather more closely set, extending back with a slight inclina- 

 tion outwards to behind middle ; third witli six, rather closer to- 

 gether, and smaller; fourth with about four small ones; sides 

 without tubercles or granules. Beneath convex, with minute gran- 

 ules as in male; no impression on apical segment. Dimensions: 

 (J, 20 X 6-5; 9, 23 x 9 mm.

Very distinct from all its congeners, and possibly requiring a 

 separate genus. The protuberant eyes, and the granulate prothorax 

 seem almost to be of generic importance. 



Specimens of (J(F) and 9(^) were kindly forwarded, for me, 

 by Mr. A. M. Lea, to M. Lesne, of the Museum d'Histoire Natu- 

 relle, Paris, for comparison with the type. In reply, M. Lesne 

 states: "Nous n'avons pas le type, qui faisait partie de la collec- 

 tion Dupont; mais le specimen F. est bien conforme a un exem- 

 plaire de la collection Fairmaire determine 'Am.BoisduvaliBoisd.,' 

 par Bohemann. G. est conforme aux specimens que nous possedons 

 sous le nom de Am. Mannerheimi Schonh." 



Chriotyphus Pascoe 

 Pasc, Journ. Linn. Soc, xii., 1873, p. 19, t. 2, f. 10. 

 Type of genus, Chriotyphus acromialis Pasc. 

 Head strongly convex, separated from rostrum by a narrow, 

 deep, circumferential sulcus. Rostrum considerably narrower 

 than head ; dorsal surface narrow, with a deeply impressed median 

 line, separating dorsum into two parallel ridges, these feebly bifur-
