Lisbon and Anglesea, N. J., and in Mr. Leng's collection are specimens 

 from Massachusetts and Iowa. 



The species is rather short, robust, not elongate and slender as 

 Mr. Blatchley describes it ; prothorax about as long as wide, tubercles 

 at most moderately distinct; sides less narrowed toward apex than in 

 siibtilis and surface more coarsely punctate. Elytra with distinct im- 

 pressions, the latter generally less deep than in aqiialis; apices squarely 

 truncate. Body beneath clothed densely with short, yellowish pubes- 

 cence ; the posterior femora in both sexes with a rather large, tri- 

 angular tooth, which is more or less distinctly serrulate posteriorly. 

 The antennal joints are stouter than in any other species known to 

 me. The last dorsal segment is emarginate-truncate at apex in the 

 male and broadly rounded in the female. 



I have seen the type of this species, which Mr. Blatchley kindly 

 sent me for examination. 



Donacia liebecki new species. 



Female. — Similar in form to megacomis but less convex, antenna? less 

 stout, elytral impressions more feeble and posterior femora with a small, 

 sharp tooth in both sexes. Head densely punctate, punctures much smaller 

 than those on prothorax ; median line deeply impressed ; frontal tubercles 

 obsolete ; antennae annulate, rather short, not extending to the middle of elytra, 

 second and third joint short, equal, fourth a little longer than third. Pro- 

 thorax as wide as long, not or at most feebly narrowing to base ; anterior and 

 posterior angles distinct and feebly prominent ; lateral tubercles obsolete ; sides 

 feebly undulate ; median line and basal impression feeble ; surface sculp- 

 tured as in subtilis. Elytra about three and one half times as long as pro- 

 thorax and about twice as long as wide at base ; apices sharply truncate ; punc- 

 tures of the regular series moderately large ; intervals moderately coarsely 

 rugose. Body beneath densely and finely punctate and moderately densely 

 clothed with short yellowish-white pubescence ; mesosternal process longer than 

 wide at apex ; legs reddish, posterior femora moderately clavate and armed 

 with a small acute tooth. Last dorsal segment emarginate at apex. Length 

 7.25 mm. 



Male. — Narrower than the female with longer antennal joints and last 

 dorsal segment broadly emarginate, posterior femora with a small, acute tooth. 



Wyandanch, Lg. Isld. ; Lakehurst and Malaga, New Jersey. 



I have seen eleven specimens collected on Long Island and at 

 Lakehurst, N. J., by Messrs. Davis, Schott and myself, and the 

 specimens from Malaga, N. J., were received from Mr. Chas. Liebeck,
