Sprague.J 382 [January 27, 



pyriform, last joint somewhat acute: rostrum carinate to the tip, 

 rather depressed, but very slightly arcuated ; together with the head 

 a little longer than the thorax : eyes small and black : thorax of 

 about the same width at base with the base of the elytra, gradually 

 and very considerably narrowing before ; above, somewhat elevated 

 on each side, the middle punctures unequal, mostly rather large, but 

 not very profoundly impressed: scutel not perceptible: elytra with 

 moderately regular striae of punctures, very slightly truncated at tip 

 upon the inner side, and terminating in a considerably produced, 

 though somewhat obtuse point, curving slightly outward : legs brown : 

 abdomen beneath with little canescent cirri. 



" Length from the tip of the rostrum nine twentieths of an inch. 



" A somewhat narrow and elongated species, and occurred in Cam- 

 bridge, Mass." 



Rhynchites viridi-seneus Rand. (Bost. Journ. Nat. Hist., 

 Vol. ii, p. 23.) 



" R.' corpore elongato viridi-seneo ; capite sub-nigro, dense punctulato; rostro 

 dilatato, supra utrinque sulcata; thorace aeneo, dense et profunde punctulato; 

 elytris viridi-»neis, seriebus vagis punctulatis; pedibus piceis. 



" Body elongated, brassy: head darker, profoundly punctured: front 

 somewhat depressed: rostrum dilated, especially at tip which pre- 

 sents a tubercle on each side ; an impressed line nearly the whole 

 length on each side: thorax brassy, densely and profoundly punc- 

 tured: elytra greenish brassy, with profound punctures, disposed in 

 irregular lines ; feet inclining to piceous. 



" Length about three twentieths of an inch. 



" Occurred at Augusta, June. 



" Perhaps allied to the R. ceratus of Say; but the elytra of that in- 

 sect are described as ' crenato-striate.' " 



[Suggested by Dr. LeConte, to be a species of Rhinosimus. e.p. a.] 



The preceding paper was written by Mr. Sprague several years 

 ago, and his later investigations required some changes, which he 

 was prevented from making by his sickness and death. I have there- 

 fore indicated in notes to each species the corrections required in the 

 original paper, and as many changes have been made in the synon- 

 omy of the species, I have prepared the following list, which gives 

 the latest adopted names of all the species described by Randall, 

 together with the name given by him, and the number of Crotch's
