REVISION OF ELEODIINI BLATSDELL. 493 



SPECIES ]\OT RECOGNIZED. 



I have not been able to recognize nor to correlate the followinij^ 

 species in the ample material at hand: 



ELEODES VICINA LeConte. 



Ni.cra, nititla, tliorace sublilittn- puiictiilato, latitudine hand louf^iore, lateribiis 

 luodicc rotuiulatis, i»o.stice subaiijiustati), olytris discrete iiiimis suhtiliter seria- 

 tum piinctatis punctis paiicis iuterjectis, femoribiis mutieis. Long. .7. 



Habitat ad tinmen Gila. 



E. qiiadricoUis attinis, at elytris punetis majoribns niagis diseretis distinctins 

 seriatis differt. Mas, snbcylindricns, elytris dorso convexis, postice attennatis. 

 Feuiina, olytris latioribns, dorso minus convexis, postice vix attennatis. 



The type is from Soaora, which is the same as that of Arizona. 

 Mr. Blancharcl writes me that the two males in the LeConte collec- 

 tion are more like ca)'hon(ui(( than quadricolli)^^ the side margins of 

 the elytra being stronger and the pnnctures at the sides more 

 substriate. 



Colonel Casey, who has no doubt seen the types, writes : '* 



Vicina is distinct from (jiKidricoUis in having mnoli finer pnnctnres. which 

 are sparser and much less asperate towards the sides, and also in several other 

 characters, among which may be mentioned the form of the prothorax, widest 

 at anterior third in quadricollis and just before the middle in vivirms, the much 

 longer posterior tarsi in the male of vicmus. Vicinus is peculiar to the Gila 

 Valley of Arizona. 



A male from M. L. Linell's collection, bearing a label with r/ehinn 

 written upon it, evidently in his handwriting, corresponds to Le- 

 Conte's description, and very closely to two males in my ow^n col- 

 lection from Arizona and without definite locality. 



Linell was considered a careful student and his lal)el bears some 

 weight. His specimen is quite dift'erent from one which Fall ques- 

 tionably refers to ricwa. 



I do not believe oicina to be distinct, and it must be a race or form 

 of rarhoixiria, or qiiadrico/Iis near the varieties anfhracuui and 

 hfsfrati.s: the form of the [)r()tibial spurs in the female must decide 

 which. 



ELEODES NITIDUS Casey. 

 The following is Colonel Casey's description : 



Rather slender, convex and snbcyllndrical, black throughout and strongly 

 shining, glabrous. 



Head rather sparsely punctate, moderately coarsely so toward apex; an- 

 tennae robust, nearly as long as the head and prothorax. the third .joint four
