Head broad, 4*5 mm. wide across eyes; granules coarse, some- 

 what depressed, showing a tendency to radiate from centre of 

 suture between head and rostrum. Rostrum very short and 

 thick, apical concavity rather shallow; external ridges not raised, 

 2 mm. across, finely setigero-punctate; internal ridges short, most 

 evident at base, where they are separated by a feeble groove; 

 median area merging into internal ridges. Sc robes and eyes as 

 in the genus. Prothorax (5x6 mm.) strongly transverse, prac- 

 tically without postocular sinuosity, with a moderately defined 

 transverse impression behind apex; evenly set with rounded 

 granules; sides granulate. Elytra (12 x 7 mm.) little wider 

 than prothorax, strongly declivous, apex rounded, base feebly 

 arcuate, humeral angles with small nodules; disc with ill-defined 

 depressions accompanied by small granules; interstices tubercu- 

 late, sutural granulate, on the other interstices the tubercles 

 becoming larger and more conical posteriorly, smaller and granuli- 

 form on declivity ; sides with interstices regularly granulate. 

 Beneath, fifth ventral segment with a shallow transverse depres- 

 sion. 



£. Elytra feebly maculate, not tuberculate, but interstices with 

 numerous, small, flattened granules in single series, duplicated in 

 places. Dimensions : (J. 19 x 7 mm.

A species with a remarkable head and rostrum, not close to 

 any other known to me. The great difference between the sexes, 

 in regard to elytral granulation, suggests the possibility of their 

 being two distinct species; but I have never seen a male with 

 fine granulation, nor a female with tubercles. The table below 

 gives a comparison of the elytral granules of four specimens (two 

 of each sex).
