Addenda. 



I. 



It is to be regretted that a number of species, described by the 

 older writers, continue to remain unknpwn, and that it will be for- 

 ever impossible to surely identify them, because of the neglect on 

 the part of their several authors to record structural characters, 

 which might enable us to form an opinion concerning their proper 

 generic positions. These species are the following : — 



1 Baridius anthracimis Boh. — Sch. Cure, III, p. 727. 



The depressed form may indicate a close relationship with Limnobaris, as 

 before remarked (p. 554), but I do not know any species with decidedly trans- 

 verse interstitial punctuation ; perhaps, like crenatus, the references to which 

 are similar in the Munich Catalogue, it may be Mexican and not an inhabitant 

 of the United States. 



2 Baridius californicus Mots. — Bull. Mosc, 1845, II, p. 372. 



May possibly be the species subsequently described by LeConte under the 

 name Centrinus nasutus. At any rate it might for the present be appropriately 

 assigned to Limnobaris. 



3 Baridius californicus Boh. — Eug. Res., Ins., 1859, p. 137. 



This is probably a species of Baris, allied to rubripes, but having the beak 

 longer and the elytral intervals smooth, or it may possibly be Onycbfiharis 

 seriata. It is said to have been taken near San Francisco. 



4 Baridius confertus Boh. — Sch. Cure, III, p. 728. 



Described from Florida. It may be assigned at present to. Onychobaris, 

 although I have never seen a representative of that genus from the Atlantic 

 regions. 



5 Centrinus dilectus Harris — Trans. Hart. Soc. Nat. Hist.,. 1836, p. 79. 

 The description enables us to assign this species to Centrinus. without much 



doubt, and it may possibly be a large female example of one of the densely 

 squamose variations of Centrinus salebrosus The locality is. not recorded. 



6 Centrinus pistor Germ. — Sch. Cure, III, p, 170. 



I can add nothing to the remarks made by LeConte (Proc. Am. Phil. Soe, 

 XV, p. 433), except to suggest that this also may be the female of Centrinus 

 salebrosus, or of a species closely allied. 



II. 

 Baris scolopacea Germ. — This species, introduced from Europe, may be 

 known by its elongate-oval, convex form and dense but uneven vestiture 

 of white and brown scales, of which a subsutural white spot at the middle of 

 each elytron is especially conspicuous. I have seen several specimens taken 

 near Philadelphia. 



Scolopacea may be attached provisionally to Baris, but the long 

 beak, separated from the head by a fine deep abrupt groove, and the
