with a transverse row of four large tubercles, apex broad, not 

 produced in the middle l)ut tuberculate above, base with small 

 scutellar lobe. Scutellum absent. Elytra with the shoulders 

 rather narrow, apex rounded. Femora reaching middle of posterior 

 declivity. Third tarsal joint simple to rather broadly bilobed. 



Scape scaly, short, in neither sex reaching apex of muzzle. 

 Prothorax with a strong carina '^continuous from base 

 almost to apex where it joins in with apical constriction 

 and forms an elongate T. Second interstice of elytra 

 with four large tubercles. Third tarsal joint simple... rubus, Pasc. 



Four prothoracic tubercles distinct, isolated. Elytra with three large 

 tubercles on 2nd interstice, suture with two conjoined tubercles 

 at summit of posterior declivity, each side of declivity with a large out- 

 wardly projecting tubercle. Two species at first sight apparently 

 identical. 



Second joint of funicle almost twice as long as 1st. Pro- 

 thoracic carina distinct, elongate, at its base forming 

 scutellar lobe. Third tarsal joint almost simple intermedius, n.sp. 



Two basal joints of funicle ec^ual. Prothoracic carina 

 absent (to the naked eye). Sutural tubercles pro- 

 jecting obliquely upwards ; in the preceding the 

 projecting is almost horizontal. Third tarsal joint 

 wide, distinctly bilobed idolus, n.sp. 



"ITlaese three species are so obviously congeneric that any system 

 which would separate them can only be regarded as purely 

 artificial.

Moderately densely clothed all over with small roundish brown, 

 scales, none of them very elongate except on tibiae and a few on 

 scape; muzzle partially or entirely bare. Ciliation minute, dingy. 



Convex, strongly tuberculate. Head almost impunctate; rostrum 

 with dense shallow, somewhat irregular punctures; ocular fovea 

 small, round, deep; eyes rather finely granulate; rostrum thick, 

 curved, feebly widening to apex (almost parallel in 5) with trace 

 of a very feeble carina at base; antenna? thick, scape inserted a 

 little in front of the middle, in neither sex reaching apex of
