form Eucnemis amoenicornis, but is readily distinguished both by the 

 generic and specific characters. 



The antenna? are about half the length of the body ; the first joint is rather 

 stout, and reaches to the hind margin of the eyes, the second is small, the 

 third about one-third longer than the fourth ; the joints 4 10 gradually in- 

 crease slightly in length and thickness, and the eleventh is longer than the 

 ninth and tenth united, parallel on the sides, and obtusely rounded at tip ; 

 the inflexed portion of the prothorax is broadly but distinctly concave, midway 

 between the prosternal suture and the side margin, for the reception of the 

 basal portion of the antennae ; the prosternal sutures are deep, and the poste- 

 rior spine rather broad. The hind coxae are gradually but strongly dilated 

 inwards, and broadly truncate behind, almost exactly as in Euc. amoenicor 

 n i s. First joint of middle and hind tarsi as long as the others united ; fourth 

 joint not dilated, claws small, simple. 



The fine carina of the head extends from between the antennas to the occi- 

 put, and might, without careful observation, be regarded as an impressed 

 line. 



Eucnemis frontosus Say seems to be better placed in this genus tban in 

 Nematodes, to which, in the List, I have referred it. The first joint of the 

 antenna? is much stouter than in N. atropos and penetrans; the in- 

 flexed portion of the prothorax is wider, and the prosternal spine is broader 

 and more obtuse. 



Epiphanis comutussc/i. Many specimens of this species were found 

 by Mr. Ulke in the mountains of Central Penneylvania. I have also seen spe- 

 cimens from Canada. 



NEMATODES Latr. 



N. simplex, fusco ferrugineus, elongatus, minus subtiliter helvo-pubes- 

 cens, capite confertim punctato, antice valde convexo, thorace latitudine fere 

 longiore, antrorsum subangustato, lateribus rectis, confertim punctato, postice 

 vage subcanaliculato ; elytris ab humeris subaugustatis, striatis, interstitiis 

 confertim punctatis ; subtus punctatus, propectore haud sulcato, tarsorum 

 articulo 4to simplici ; antennis articulis 3 -10 sequalibus. Long. 7 - 5 mm. 



One specimen from New York in the collection of Mr. Ulke. Resembles in 

 appearance Agriotes oblongicollis. This species differs from those pre- 

 viously described by the entire absence of vague grooves for the reception of 

 part of the antenna?, and by the fourth joint of the tarsi not being dilated or 

 lobed. The first joint of the hind tarsi is as long as the three following. 



CEROPHYTUM Latr. 



C. convexicolle, subcylindricus, niger opacus, tenue pubescens, 

 dense fortiter punctatus, thorace longitudine plus duplo latiore, lateribus valde 

 rotundatis, angulis posticis baud prominulis ; antennarum articulo 3io lato 

 triangulari, 4to et 5to ad medium obtuse ramosis, tibiis tarsisque obscure 

 ferrugineis. Long. 7 mm. 



One male specimen was sent me by my friend the late Dr. Schaum, as found 

 at Sacramento, California. It resembles closely the male of C. pulsator, 

 but the thorax is more rounded on the sides, especially behind the middle, so 

 that the hind angles are much less obvious ; the third joint of the antenna? is 

 also quite different in form, being triangular, with the outer angle obtusely 

 and slightly produced ; the fourth and fifth joints are produced at the middle 

 of the outer margin into obtuse processes ; the processes of the outer 

 joints originate near the base of each joint; in C. pulsator all the 

 processes originate at the base of their respective joints, and the third joint is 

 not different in form from the fourth. The tibia? and tarsi are tinged with 

 ferruginous.
