Sprague.] 376 [January 27, 



Agrilus vittaticollis Band. This species is now known, a 



specimen being in Dr. Harris's cabinet. 



[Found occasionally in various parts of this State, and seems ot 

 live on the shadberry (Amelanchier canadensis), e. p. a.] 



Elater subrufa Rand, is doubtless Nematodes simplex LeC. 

 (Proc. Acad. Nat. Sci. Phila., 1866,388). Only a single specimen 

 known in Mr. Ulke's collection. 



Elater filius Rand., Cardiophorus, of LeConte's list, unknown. 



Elater basalis Rand, may be, as suggested by Dr. LeConte, 

 Limonius stigma. Yet I consider it doubtful, because Dr. Harris had 

 a male of the species in his cabinet at that time, No. 531, and sup- 

 posed to be a variety of scapularius, so named in Harris's Insects of 

 Mass., 1835. 



Elater macilentus Randall, unknown. 



Elater graciliformis and tenuicollis Rand, are varieties of 

 one species, the former with elytra black, the latter testaceous; they 

 belong to the genus Oestodes. 



Elater honestus Rand, is, without doubt, the Sericosomus fiusi- 

 formis LeC, which must be put as a synonym. 



Elater serarius Rand. This species was described in Europe be- 

 fore Randall's paper appeared as E. resplendens Esch., (Jide Horn) 

 and belongs to Corymbites. 



Elater anchorago Rand., Kendalli Kirby, was described by 

 Olivier in Europe as ceneicollis (fide Horn), and belongs to the 

 genus Corymbites. 



Omalisus fraternus Rand, is now known, and belongs to the 

 genus Eros. 



Malachius cseruleus Rand, is probably a variety of Anthocomus 

 flavilabris Say (fide Horn). 



Tomicus gulosus Rand, is Xyloterus bivittatus Kb. 



Dircsea decolorata Rand, is Xylita laevigata Hellen (fide 

 Horn). 



Lixus rubellus Rand., unknown. 



Lixus calandroides Rand. I have been able to recognize; it is 

 found during July on Nantucket Beach. 



Rhynchites viridi-seneus Rand., unknown. 



Galeruca salicis Rand. Found in Dr. Harris's collection, 

 No. 1564, determined by Dr. Harris as sagittaria Gyll, which being 

 previously described takes the precedence.
