bossy nodule present at base of external ridge, separated from 

 rest of ridge by a constriction; median area raised; internal 

 ridges noduliform. Scrobes strongly curved. Eyes ovate, com- 

 pressed from behind forwards. Prothorax granulate. Elytra 

 striate, interstices with flattened granules. The rest as in 

 Talaurinu8. 



I have proposed this genus to receive the following species. It 

 might be regarded as an aberrant form of Talaurinus, but its 

 connection with the rest of the genus is so remote as to warrant 

 its separation. The structure of the rostrum is most remarkable, 

 particularly the projections at the base of the rostral ridges, 

 these being on the rostrum, and not at the side of the head as in 

 Notonoplies. The compressed flattened appearance of the eyes 

 is also characteristic.

9. Large, robust, oblongate, convex, strongly declivous pos- 

 teriorly. Black, subnitid; practically without scales, except 011 

 the appendages; setae minute, black. 



Head large, very short, and extremely convex, sparsely setigero- 

 punctate, a few obsolete granules at base of rostrum. Rostrum 

 short and thick, much wider than long, hardly excavate; apical 

 marginal plate little emarginate, bordered behind by a deep 

 transverse sulcus; external ridges divergent posteriorly, broad, 

 rounded and convex in profile, dilated at base into a large nodule 

 separated from the rest of ridge by a constriction; apical sulcus 

 bordered posteriorly by a transverse ridge, continued back as a 

 slightly elevated median carina; internal ridges situated at base, 

 on either side of median area, large, noduliform, convergent. 

 Scrobes deep, strongly curved. Eyes oblong-ovate, compressed. 

 Mentum with a strong mesial tooth. Scape rather short but 

 passing eye. Prothorax (7*5 x 9 mm.) rotundate, convex, sides 

 rounded, apex very broad, with a feeble sinuosity on either side, 

 without definite lobes; base broad, truncate; disc without impres- 

 sions, closely and somewhat coarsely granulate. Sides granulate. 

 Elytra(17 x 10 mm.) ovate, sides rounded, apex slightly produced,
