the LeConte series, and there is, I think, sufficient individual 

 variability in the lengths of the funicular joints to cover the 

 differences given by Dietz, which do not look as important 

 in the specimens themselves as they appear on paper. 



A. rubidus Lee. 



The accessory cusp on the front thighs of which Dietz 

 speaks in his table, is faintly indicated in the type, and is 

 rather more pronounced in some examples of prohindus, in 

 which both LeConte and Dietz say it is absent. The two 

 species are, of course, quite distinct, but the accessory cusp 

 is not to be relied upon as a distinguishing character. 



A. haeinatopus Boh. 



Both LeConte and Dietz have expressed themselves as 

 pretty well satisfied that this is the same as sycophanta Walsh., 

 and I am myself convinced of it. Bolteri Dietz and corifusus 

 Dietz are exceedingly close to and, perhaps, only varieties of 

 the above ; but of this I do not yet feel assured. 



A. bruiinipeniiis Mann. 



There is no very good reason for believing that the single 

 example so identified by LeConte is the true brunnipennis. 

 Mannerheim's description is very brief, but calls for an insect 

 two lines long excluding the rostrum, finely pubescent, pitchy 

 black with brown elytra. LeConte's specimen is a 9 , con- 

 siderably smaller, uniform in color, and rather sparsely but 

 truly squamose. 



Specimens taken by Mr. H. S. Barber at Blair's Ranch, 

 Humboldt County, California, are apparently identical with 

 the LeConte specimen, which was taken by Crotch at Geysers, 

 California. This species should be placed near rmu^iniis of 

 the squamos2is group, differing from the latter by its more 

 coarsely punctured thorax, more unevenly disposed vestiture 

 which is condensed on the median line and at the sides of the 

 prothorax, and more or less at the middle of the fourth and 

 toward the base of the sixth elytral intervals. 



I have seen a number of examples of the Californian moru- 

 lus with brown elytra, and here the vestiture would fit Man- 

 nerheim's expression " tenuiter pubescens," but the pro- 

 thorax is not conspicuously " profunde rugoso-punctate,"
