UNRECOGNIZED SPECIES. 



1. Rhynchitas virdiseneus Randall, Bost. Journ. Nat Hist., ii, 23. 

 R. corpore eloagato virkli-seneo ; capite subnigro, dense punclulato ; 



rostro dilatato, supra utrinque sulcato ; thorace aeneo, dense et profunda 

 punclulato ; elytris viridi-oeneis, seriebus vagis punctulatis ; pedibus piceis. 

 Body elongated, brassy. Head darker, profoundly punctured ; front 

 somewhat depressed ; rostrum dilated, especially at tip, which presents a 

 tubercle on each side, an impressed line nearly the whole length on each 

 side. Thorax brassj', densely and profoundly punctured. Elytra green- 

 ish brassy, with profound punctures disposed in irregular lines ; feet in- 

 clining to piceouo. Length about three-twentieths of an inch. Occured 

 at Augusta (Maine), June. Perhaps allied to the R. ceratus oi Say, but 

 tli3 elj^tra of that insect are described as crenite-striate. 



2. Rhynchites congrua Walker, Nat. in British Columbia by J. K. 

 Lord, ii, 331. 



Nigric.inte cyaiea, aspsre punctata ; rostro thoracis longitudine, thoracis 

 lateribus convexis ; elytris latis, lateribus sub-convexis. 



Blackish blue, roughly punctured. Rostrum as long as the thorax, 

 slightly dilated towards the tip. Thorax narrowed in front, sides convex. 

 Elytra much broader than the thorax and about twice its length ; sides 

 slightly convex. Length 3 lines. 



Rhynchites humeralis Bjh., Eugenics Resa, Ins. 117. 



Oblongo-ovatus, modice convexus, niger tenuiter pubescens ; antennis 

 tibiisque ferrugineis ; prothorace confertissime punclulato, lateribus parum 

 ampliato ; elytris crebre punctato-striatis, macula humerali rufo-testacea 

 ornatis. Long, 2 mm.; lat. l^mm. 



Var. a- elytris rufo- ferrugineis dorso infuscatis. 



If this species properly belongs to our fauna, it will be readily recognized 

 without the aid of the long description which accompanies the above 

 diagnosis. 



3. Polydrosus ainericanus Gyll., Sch. Cure, ii, 136. 



" Oblongus. niger opacus, cinereosquamulosus, fuscoque pubescens ; an- 

 tennis tibiis tarsisque ferrugineis ; thorace pulvinato, confertim punctato ; 

 elytris punctato-striatis, apice acuminatis, in dorso plagiatim nigro-varie- 

 gatis. America borealis, ex musseo Dom. Com. Mannerheim, ad de- 

 scribendum, amice communicatus.
