of funicle. Prothorax moderately transverse, apex subtubular; 

 scarcely tuberculate beneath fascicles; densely and strongly- 

 punctate, punctures mostly exposed. Elytra once and one-third 

 wider than prothorax; shoulders rounded, sides parallel to apical 

 third, apex almost conjointly rounded; subtuberculate beneath 

 fascicles; striate-punctate, striae feeble, punctures moderately 

 large, not approximate; interstices (except at fascicles) flat, con- 

 siderably wider than punctures. Under surface moderately, 

 strongly punctate. Mesosternal receptacle strongly transverse, 

 walls not thin. Posterior femora strongly, the others rather 

 feebly dentate. Length 5, rostrum 1 J; width 21 mm.

The shape of the mesosternal receptacle is very different from 

 that of T. camelus or T. sellatus, and would, perhaps, almost 

 justify the erection of a new genus; the antennal club is unusually 

 short. Owing to the loose nature of the scales (especially on the 

 prothorax), the punctures can be distinctly seen without abrasion. 

 The elytral fascicles are of an unusual character, appearing more 

 like transverse dark velvety patches than the elongate fascicles 

 of normal forms. 



Tychreus sellatus Pasc; I.e., No.5523. 



Elliptic-ovate, convex. Chocolate-brown; rostrum darker, 

 base of scape red. Densely clothed with large soft ochreous-grey 

 scales, almost uniform in colour throughout, except for a very 

 distinct obovate patch of brown scales about the scutellum : 

 partly on the prothorax but mostly on the elytra. Prothorax 

 with six fascicles, of which the four median ones are feeble and 

 the two apical scarcely traceable; elytra with semierect patches 

 in feeble clusters but scarcely forming fascicles. 



Head convex, very slightly flattened between eyes. Sides of 

 rostrum moderately incurved, base moderately strongly punctate. 

 Scape inserted slightly nearer apex than base, slightly shorter 

 than funicle. Prothorax almost as long as wide; sides rounded, 

 apex about half the width of base; densely punctate, punctures 

 strong, round, deep, more or less concealed; with a feeble median.
