Hab. — Massachusetts, New York, Pennsylvania, Michigan, West 

 Virginia. 



According to Dr. Hamilton, sometimes abundant in Westei'n 

 Pennsylvania " on Viburnum acerifolmm going out of bloom, June." 



For convenience of comparison I give below, in parallel columns, 

 the characters of most use in the separation of the last thi'ee species : 



Puritannm. 

 Length 2-2.4 mm. ; 



Beak conspicuously lon- 

 ger in the J , often shorter 

 than the head and pro- 

 thorax in the % ; 

 surface finely strigoso re- 

 ticulate and dull almost 

 throughout; 



color piceous brown 



throughout. 



Second joint of antennse 



( % ). third ( 9 ) reaching 



the eye. 



Prothorax nearly as long 



as wide, widest at base ; 



apical constriction feeble, 



behind which the sides 



are nearly straight. 



Bassal fovea small, nar- 

 row. 



Elytra less elongate. 

 Pubescence most notice- 

 ably condensed at base 

 on third interval. 



Darker subapical sutural 

 spot not or scai'cely evi- 

 dent. 



Posterior callus feeble or 

 wanting. 

 Claws feebly toothed. 



Umbonifenim. Herculaniim. 



3-3.1 mm. ; 2.5-2.9 mm. 



Beak subequal? (sexes not Beak subequal in the 



yet separated) ; sexes. 



iine sculpture rather less 

 marked; surface a little 

 more shining; 



color piceous brown 



throughout. 



First joint of antennte 



reaching the eye. 



Prothorax somewhat in- 

 termediate in sliape, but 

 never with a well-marked 

 basal contraction. 



Basal fovea much larger, 

 shallow, more vague. 

 Elytra more elongate. 

 Pubescence more ditfuse 

 at base, not conspicuously 

 condensed on either the 

 sutuial or third interval. 

 Subapical sutural spot 

 conspicuous. 



fine sculpture scai-cely 

 evident, except near the 

 base; surface polished 

 and shining; 

 color reddish brown; base 

 and extreme tip darker. 

 Slightly variable, first 

 joint nearly but never 

 quite reaching the eye. 

 Prothorax n)ore trans- 

 verse ; apical constric- 

 tion distinct; sides well 

 rounded and narrowed 

 before the base, which 

 is not wider, if as wide, 

 as near the middle. 

 Basal fovea as in puri- 

 tanum. 



Elytra less elongate. 

 Pubescence most notice- 

 ably condensed at base 

 along the suture. 



Subapical sutural spot 

 conspicuous. 



Posterior callus promi- Posterior callus feeble, 

 nent. Claws more strongly 



Claws feebly toothed. toothed. 



The color is, in some degree, variable in all, but puritannm is, as 

 a rule, darker than the other two. I am well aware that the cre- 

 ating of two new species at the expense of hercuianum will seem to 

 some of doubtful propriety, and I must confess that I hesitated lono-
