174 AMERICAN COLEOPTERA. 



105. A. puritan II in n. sp. — Moderately eloHgate, wider behiud, brown ; 

 the suture .slij^htlv darker; vestiture consisting for the most part of grayish hairs, 

 which are coarser and condensed in the basal and apical regions, more especially 

 in a curved line, posteriorly convex on each elytron before the middle, and in a 

 transverse subapical band, between these the hairs are very fine and sparse, pre- 

 senting the apjiearance of a wide median denuded fascia. In some examples the 

 entire region behind the apical band is densely clothed with grayish white pubes- 

 cence, with yellowish and reddish hairs intermixed. The sides of the meso and 

 metasternum, as well as their side pieces, are also densely clothed in well-pre- 

 served examples. The beak is shorter than or equal to the head and prothorax 

 {%), distinctly longer (9 ), parallel, feebly dilated, finely sculptured and rather 

 dull nearly to the tip in both sexes. First antennal joint subeqnal to the next 

 two ( 1 ), or a little longer ( 9 ), second ( "J, ) or third { 9 ) reaching the eye. Front 

 more or less canaliculate; eyes prominent. Prothorax nearly as long as wide, 

 slightly wider behind ; apical constriction feeble; basal almost wanting; surface 

 moderately punctate ; basal fovea small, elongate. Elytra about one-half longer 

 than wide, widest behind the middle; humeri moderate; intervals not wide, 

 somewhat convex. Beneath moderately punctate; tarsi rather stout; claws 

 feebly toothed. Length 2.-2.4 mm. ; .08-.096 inch. {PI. V, fig. 16.) 



Hab. — Massachusetts, Pennsylvania, New Jersey, District of 

 Columbia, Illinois, Wisconsin. 



Tliere seems to be no sexual difference, other than in the length 

 of the rostrum, nor in my experience is the abdomen ever deplexed 

 at the tip in the male. The relation of this species to herculanum 

 is referred to under that species. 



106. A. II 111 bo 11 ire rum n.sp. — Of the same general facies as the preceding, 

 but larger and a little more elongate. The beak is slightly more .shining, the 

 antennae inserted nearer the base, the first joint reaching the eye. The sides of 

 the thorax are a little more arcuate posteriorly, with a larger but shallow basal 

 fovea. The base of the elytra is more diffused ly clothed with pale hairs, which 

 are not so obviously condensed at the base of the third interval, or along the 

 suture, as is respectively the case in the preceding and following species. The 

 sides of the body beneath are less densely pubescent, the elytral intervals are 

 wider, and the fifth bears on the declivity a prominent callus. Length 3.-3.1 

 mm. ; .12 inch. 



Only five examples seen, and all from Maryland (Odeuton and 

 Harper's Ferry). 



There are no sexual differences observable, though it is probable 

 that both sexes are present. 



107. A. Iierculailiiiil Smith. — Similar to the two preceding in general 

 appearance, but differing from both by the rather strongly rounded sides of the 

 prothorax, the shining beak and more strongly toothed (^laws. There are abso- 

 lutely no external means of distinguishing the sexes. Length 2 5-2.9 mm.; .10- 

 .12 inch. (PI. V, fig. 1.5.)
