Hy Major Tlios. IKroiiii. 



ORGHYMONTIA Broun, gen. iiov. . .

 paipi very elongate, basai joint minute, subglobular; 2'"' very elon- 

 gate, gradually incrassate, about balf of tbe wliole length ; 3"' nearly 

 twice as long as broad, lliickened towards tbe extremity; 4"> longer 

 and more siender. Head horizontal, narrowed anteriorly. Labrum 

 large, transversal, with a narrow, deep, médian notch, rounded 

 towards the sides. Eyes rotandate, prominent, situated at the sides 

 near the base. Antennœ siender, little more than half length of 

 maxillary paIpi ; basai joint subcylindric, 2'"' quite as long, only 

 slightly thicker ; 3'^'' about as long as 2'"' but more siender; 4*^'' shor- * 

 ter; 5-7 small; club triarticulate, basai joint subquadrate, 9'^'' rather 

 larger, oblong. Thorax not emarginate in front, its sides obtusely 

 angulate near the middie, distinctiy sinuate and narrowed towards 

 the obtusely reclangular poslerior angles, base truncale. Scutellum 

 absent or obsolète. Elytra apparenlly connate, hardly any wider 

 than thorax at the base, but with small obtusely dentiform shoul- 

 ders; they are oblong-oval, broadly rounded behind, but with a 

 minute yet distinct spiniform process there. Legs elongate minu- 

 tely pubescent; tibiae ahnost straight, the intermediate on the 

 inside with an obtuse angulation below the middie. Tarsi elongate

 larly emarginate. 



I hâve named this peculiar new genus of Hydrœninœ after 

 M. A. d'Orghymont, the will known Belgian Coleopterist, in admi- 

 ration of the fine work lie bas done in connection with the 

 Coleoptera belonging to this diffîcult group.

Elongate, medially narrowed, slightly convex, nitid glabrous ; 

 piceo-niger, legs and paIpi fusco-rufous; anlennae testaceous; tarsi
