Galifornia CPalm Springs, Colorado Desert). 



A single specimen of this interesting species was taken by Mr. 

 H. C. Fall under a stone ; its sex is not apparent. There is another 

 species of this genus still undescribed in the cabinet of Mr. 

 Schwarz ; it is larger and stouter than macer. 



Notes — The S. hicoJor, referred to by Schaufuss in suppressing the name 

 itcofor Lee. , is evidently the Antliicus Mcolor oi Fabricius, from South Amer- 

 ica, and not the S. bicolor of Denny, as I surmised (ante, p. 371). Anthieus 

 Mcolor is said by Erichson to be allied to clavipes Say (Schaum, Mon., p. 18), 

 but there seems to be too much doubt connected with the subject to warrant a 

 ■change of name for the present, and I would therefore advocate the retention 

 of the name given by LeConte. 



The species placed in Euconnus by Dr. Sharp (Biologia Cent.-Amer. ) will, 

 I think, be forced ultimately into several distinct genera. On looking over 

 the admirable figures on the plate, it seems natural to place giraffa, mutandus 

 and guatemalenus, for example, in one genus, and dieriquensis and germanus in 

 another, the latter distinguished by peculiarities of pronotal sculpture and an 

 unusually elongate antennal club. Calmis, as before remarked, will probably 

 enter the genus Pycnophus, although the third joint of the maxillary palpus, 

 as figured, is different from that of P. rasus, the type of the genus; it is pos- 

 sible, however, that this may be an oversight on the part of the artist. Gra- 

 cilicomis, incultus and some others appear to form each the type of a distinct 

 genus. 



. The genus Napochus of Thomson, is in all probability closely allied to Con- 

 nophron, but differs apparently in the more prominenb tempora and trans- 

 verse eyes, and also in having a distinct plica at the sides of the thoracic base. 



ADDENDA. 



There are several described species in this family within our 

 faunal limits, which I have not been able to place satisfactorily in 

 the tables previously given ; these are added as follows for the 

 sake of completeness : — 



Scydmaenus consobrinus Lee. — Proc. Acad. Nat. Sci., Phila., 1852, p. 154. 

 — Piceous-black, the head glabrous; prothorax rather long, pilose, rounded 

 and narrowed anteriorly, transversely impressed at the base; elytra sparsely 

 pilose, foveate at the base; antennae clavate, with the penultimate joints 

 rounded. Length .05 inch. New York. 



Precisely similar to clavipes but differing in the antennae, these being some- 

 what longer than the head and prothorax, with joints three to six equal, 

 closely connected and not longer than wide; seven a little larger and slightly 

 conical, eight to ten rounded, not longer than wide; eleven about }4 longer 

 and subacute. 



This species may be placed immediately after Euconnus clavipes 

 in the table.
