Ilab. Flv River, L. j\l. D'Albertis. 



A broader species than its congeners, with a rather short 

 rostrum strongly curved at the base but not gibbous. In one 

 specimen I examined the second abdominal segment has two 

 mammilliform eminences. 



I31U. I. rufipennis, n. sji. Subelliptica, nigro-fusca nitida; elytra rufa; 

 oculi tenue granulati; rostrum cylindricum, modiee arcuatum, antice squamis 

 niveis indutum; antennie infascat;e, ante medium rostri insertoe; prothorax 

 paulo longior quam latior, remote punctatus; elytra cordiformia, seriatim 

 punctata, punctis remotis; pedes sparse albo-squamosi; femora sublinoaria, 

 mutiea, supra dense albo-squamosa; tibias sulcato-punctatae. Long. 3 mm.

This species is at once distinguished by its reddish elytra and 

 rostrum nearly of the same thickness throughout. 



311. I. pulicaris, n. sp. Ovalis, nigra nitida, elytris rufo-castaneis; ro- 

 strum parte basali modiee incrassata, in medio tricarinatum, vage albo- 

 squamosum; antennas pallide ferruginea^; prothorax sat confcrtim punctatus ; 

 elytra subtilissime striato-punctata, striis fere oksoletis, punctis remotis; 

 infra pedesque picei; femora subdentata, posteriora iutus serrato-producta; 

 metasternum late cxcavatum. Long. 4 mm.

In this species the pectoral canal is less cavernous at the
