NORTH AMERICAN COLEOPTERA. 143 



AEOIAI.ITES Mann. 



Tlie first appearance of this name is in the Dejean Catalogue, 

 1837, p. 131, where it is ph^ced among the Scydmsenidse. The next 

 notice of the name occurs in Bull. Mosc. 1845, i, p. 33, in the fol- 

 lowing manner : 



Elosomaf Galifornica M. Noire et luisante, les elytres sont striees 

 par sillons, tronquees a 1' extremite et un peu dehiscentes. Les 

 antennes sont comme chez les Scydmaenus. Serait-ce pent etre V 

 Aegialites debilisf. 



The genus Elosoma has never been described. Aegialites was first 

 quite fully described by Mannerheim, Bull. Mosc. 1853, iii, p. 180, 

 and the species debilis. ]\tannerheim remarks: " I have examined 

 three specimens ; one indicated as from California in the cabinet of 

 Motschulsky, another taken at Sitkha by Fred. Sahlberg, and a third 

 collected by Holmberg at Woskresensk bay, peninsula Kenai." 



If we can accept the statement of Mannerheim, it is evident that 

 both he and Motschulsky had the same species before them, and 

 that, bad as the description is, califoniicus will, by Manuerheim's 

 admission, have priority over debilis. 



Recently a species has been collected in California by Mr. Chas. 

 Fuchs differing materially from debilis, and in a manner which could 

 hardly have escaped the notice of Mannerheim. 



Head and thorax comparatively smooth, the punctures indistinct and sparsely 

 placed; elytra "striato-subsulcate" without distinct punctures; underside 

 of body nearly smooth califoriiicus. 



Head and thorax coarsely, moderately deeply and rather closely punctate ; elytra 

 vaguely subsulcate and with rows of moderately coarse punctures; under- 

 side of body coarsely punctate, but sparsely Fiichsii. 



Ae. Fuclisii u. sp. — Oblong, piceous, surface with distinct bluish greeu 

 lustre. Head moderately closely punctate. Thorax a little wider than long, 

 slightly narrower at apex than at base, widest in front of middle, sides slightly 

 arcuate, disc moderately convex, rather coarsely and moderately closely punc- 

 tate, median line finely impi-essed posteriorly. Elytra oval, wider behind, 

 vaguely substriate with coarse punctures moderately closely placed. Body be- 

 neath and legs piceous, sides of body and abdomen sparsely punctate. Length 

 .10 inch. 9 ; 2.5 mm. ; male a little smaller. 



In californicus the hind tibiae are quite abruptly bent near the 

 apex, in the present species feebly so. The two species differ con- 

 siderably in size, californicus being nearly twice as long. 



Occurs in California, Mendocino County ; collected by Mr. Chas. 

 Fuchs, to whom I owe the pair in my cabinet.
