I can form no idea as to where the species should be placed. — D. S.

" Elongato-ovalis, postice valde acuminata, convexa, supra undique valJe punctata; capite et thorace

" Cette espfece est bien voisine de I'llydr. nigrita, F. ; mais elle est un peu plus graijde, plus allonges,

chez les individus de la Provence."

The species is probably v(iry closely allied to H. nevadensis, and H. celatus, (Nos. 632, and 633). — D. S.

elj'tris fulvo-fen-ugineis, pilosis in medio macula atra irregulariter omatis ; corpore atro ; pedibus 

 fernigineis." 



" Cet Hydropore ressemble beaucoup a I'H. lituratus, avec lequel il ne pourra utre confondu a cause de
