REVISION OF ELEODTINI BLAISDELL. 361 



abruptly terminating where the a})ical margin of the dorsal plate 

 should be. Pencil of hairs at tip of appendage quite long. Other- 

 wise as in yarvieoUis. 



Tlahitat. — California (Eussian settlement, Fort Ross, Eschscholtz). 

 My series is without definite locality data and were probably collected 

 by Mr. G. W. Dunn. 



Number of specimens studied, 61. 



Type in the Eschscholtz collection ? 



Tyfe-locality. — Russian settlement. Fort Ross, California. 



Salient type-characters. — Thorax transyerse, densely punctate ; sides 

 rounded ; base coarctate. Elytra depressed on the dorsum and fove- 

 olato-punctate. Antennae subfiliform (Eschscholtz). 



Diagnostic characters. — Eschscholtz says that the thorax is nnich 

 broader than long, strongly rounded on the sides and Avith the nar- 

 row margins more or less strongly reflexed. Elytra Avith the dorsum 

 distinctly flattened (but convex) and not tnarkedly declivous hehind; 

 side margins of the humeri very distinct; coarsely punctured at mid- 

 dle, seriate and granulate laterally. 



The type must have been a male. My series, although not exactly 

 typical, consists of both sexes. Mr. Blanchard has kindly made the 

 necessary comparisons in Cambridge, and writes that a male (now 

 before me) " is not quite typical, being less ronvex." It must l)e 

 noted, in order that the above descriptive remarks be not considered 

 inconsistent, that the elytra are depressed and at the same time moder- 

 iitely convex. 



Typical parricoIlJs resembles scahrosa more than it does planata; 

 the latter has the sides of the pronotum impressed, the elytra are more 

 distinctly oval, and more gradually declivous behind in the male, 

 and not as roughly sculptured ; there is more or less evidence of a 

 serial arrangement of the punctures on the dorsum; there the punc- 

 tures are simple and the strial punctures are arranged in a straight 

 line as usual, but greatly obsciu-ed by the very irregularly ditl'used in- 

 terstitial punctures, both being of the same size. 



I can not discover any signs of a serial arrangement in the typical 

 parvicollis.^ where the sculpturing is coarser and more scabrous. 



Producta is distinctly oblong, with the sides of the elytra parallel, 

 the dorsum distinctly flattened and with the hiuneri \qv\ prominent 

 in both sexes. 



Of course the extremes are more difficult to separate, but I consider 

 them no more so than in some parts of the subgenus Melaneleodes. 



Two males before me are very coarsely and densely sculptured. 

 One from Trinity Count}^ is especially so; the elytral punctures on 

 the dorsum show evidence of serial arrangement of the interstitial 

 punctures; both vseries are of the same size and submuricate, laterally 

 the punctures are muricato-tuberculate, approaching eonsohrtna and
