Dans ma « RoYision des Grands Hydrophiles » (p. 188 de ce vo- 

 lume), j'ai complètement oublié de mentionner ÏHydropInlus pollens 

 Sharp, qui est un Dlbolocelus me paraissant très voisin des D. Ober- 

 tiiiiri Rég-. et gibbosus Rég. Comme je ne connais pas celte espèce, j'en 

 donne ici la description de l'auteur : 



Hydrophilus pollens Sharp, Biol. Centr. Amer. Suppl., Vol. I, 

 Pt. 2, sept. 1887, p. 7G1. — Ovalis, conrexus, nif/er, supra viridi-oU-

 Iji'osterni processu profiinde fisso, utrinque anterius dente acuminato 

 deorsum spectante; femoribus posterioribas validis; abdomine pubes- 

 rrute, segmenta penultimo medio linea laevigata et earinata, posterius 

 in dente libero prodncta, segmenta ultimo média spatio parce anterius 

 angusto laevigata; palpis niaxillaribus maris dilata fis. 



Long. 30-35 mill.

Of this species I bave before me three examples, and bave no doubt 

 that the example from Mexico vith the maxillary palpi dilated is the 

 same species as the individual from Demerara with the palpi simple, 

 allboiigb in this presumed maie there is not the slightest incrassatlon 

 or peciiliarity of the front tarsi, wich are quite like those of the fi'- 

 male; the second example from Mexico lias unfortunatly lost the palpi. 



II. pollens is onof agroup of species distinguished by the prosternum 

 in front being divided into two lobes, by llie hind body being nearly
