cvlindric (or nearly so), but a little attenuated at the apex when 

 viewed laterally, its sides striolate near the base ; antennae 

 inserted a little in front of the middle of the rostrum, 2nd joint 

 of f unicle short ; eyes moderately finely granulated ; presternum 

 rather unusually elongate in front of the anterior coxae, its 

 anterior margin but little emarginate, mesosternum at least 

 moderately wide ; femora unarmed ; anterior tibiae mucronate at 

 apex ; claws divaricate, simple ; basal ventral suture straight or 

 nearly so ; 3rd and 4th ventral segments together shorter than 

 2nd, their sutures angulated laterally ; prothorax not bisinuate at 

 base, its ocular lobes very feeble ; intercoxal process of hind body 

 wide, truncate or nearly so in front ; general form wide and short 

 as compared with many genera of Erirhinidte. 



Cydm^a obscura, sp.nov. 



Ovata ; picea, antennarum scapo rufescenti ; squamis (supra 

 brunneis albisque intermixtis, subtus albis solis) sat dense 

 vestita ; rostro prothoraci longitudine sequali ; antennarum 

 funiculi articulo 1° quam 2"^ 3"^ que conjuncti vix breviori, 

 2'' 3° paullo longiori, ultimis 2 fortiter transversis, clava sat 

 lata quam latiori vix duplo longiori ; prothorace leviter 

 transverso, antice angustato, lateribus leviter arcuatis ; 

 elytris striato-punctulatis, humeris paullo callosis ; meso- 

 sterno quam C . luctuosce (Pasc.) paullo angustiori. 



[Long. 1?, lat. ? line. 

 The lighter scales of the upper surface are extremely nitid and 

 have a silky brownish gloss in some lights, while from other 

 points of view they appear to be white ; their arrangement is 

 very confused ; on the prothorax they are very evenly and closely 

 sprinkled ; on the elytra they are sprinkled chiefly about the 

 base down the suture, and in the form of a very indistinct fascia 

 behind the middle, the darkest colouring being immediately in 

 front of this quasi-fascia. Differs from C. himaculata, Pasc, by 

 its antennse, tibiae, and tarsi not being of a ferruginous colour, 

 its differently marked elytra, &lc.
