Dedicated to Mr. T. V. Wollaston, who has increased our knowledge 

 of the Cossonides by his valuable essay on the genera and species of the 

 Canary and adjacent islands. 



W. quercieola. (? Rhyncolus quercicolus Boh. Schouh. Gen. Cure. 

 VIII., 2, p. 281.) 



Black, feebly shining. Rostrum finely punctured at tip, more coarsely, 

 but much less densely at base. Thorax longer than wide, nearly cylin- 

 drical, very slightly narrowed in front, surface coarsely but not densely 

 punctured. Elytra cylindrical scarcely wider than the thorax, humeri 

 moderately prominent, surface finely striate at base, striae much deeper 

 at apex, with very coarse and deep punctures moderately closely placed ; 

 intervals feebly convex, uni-seriately punctulate, tip of elytra with mar- 

 gin slightly prolonged and feebly rerlexed. Body beneath black, feebly 

 shining, coarsely variolato-punctate. Legs piceous sparsely punctured. 

 Length .12 inch ; 3 mm. 



South Carolina, Louisiana, Georgia. I quote the synonym with some 

 doubt, although the specific description agrees very well. 



Amauroiuiixus Fairm. 



A ? nitens, n. sp. 



Black, shining. Rostrum half as loug as thorax, finely punctured, and 

 with an impressed puncture between the eyes. Thorax as wide as long, 

 oval, base slightly wider than apex, sides moderately arcuate, surface 

 moderately convex, coarsely and regularly, but not densely punctured. 

 Scutellum small, smooth. Elytra oblong, humeri moderately prominent, 

 sides feebly arcuate, slightly broader behind the middle, margin slightly 

 prolonged at tip, and somewhat reflexed, surface finely striate, striae 

 moderately punctured, intervals (slightly convex at base) flat, finely uni- 

 seriately punctured. Body beneath shining, coarsely and sparsely punc- 

 tured, abdomen more finely punctured. Length .10 inch; 2.5 mm. 



I refer this species with doubt to the above genus, as the characters 

 have never been exposed at sufficient length to determine the point 

 definitely. It corresponds with the description as far as it goes. The 

 following characters are added for the present species, that its position 

 may be determined. 



Rostrum slightly longer than the head, slightly arcuate. Scrobesdeep, 

 beginning at the middle of the rostrum, encroaching on the eyes behind. 

 Eyes oval, slightly transverse, moderately convex, not coarsely granu- 

 lated. Anterior coxae very closely approximated, middle moderately 

 distant, hind coxa? distant, in'tercoxal process short, slightly arcuate in 

 front. Third tarsal joint moderately emarginate. 



Occurs abundantly in Florida. 



Lymantides. 

 The distinction between this group and the next is not very well 

 marked in the genus, which we have in our fauna, the only difference 

 being in the short mesosternum of the former, aud the longer mesoster-
