March, I9i6.] LenG : NOTES ON CyCHRINI. 41 



Canada, West Virginia, Virginia (Roeschke), and Indiana? (Leconte 

 coll. fide Blanchard) are plausible; but the "Washington, D. C," 

 locality is contrary to probability and to all the information I can 

 gather, and is possibly also based on the " Charleroi " confusion men- 

 tioned above. 



It is useless to repeat here the minute descriptions of these three 

 forms, which have been well written by their respective authors; 

 but briefly it may be said that brevoorti is a comparatively small 

 (about 12 mm.) dark aeneous insect, while nitidicollis and schaumii 

 are both larger (about i8 mm.) and more brilliantly colored, differ- 

 ing between themselves in form of thorax and in punctuation. The 

 main object of these notes is to point out that brevoorti is not a 

 synonym of nitidicollis; and that no one of the three forms under 

 discussion is an Atlantic coastal plain insect or ordinarily liable to 

 be found at Washington, D. C. 



There are other criticisms on Dr. Roeschke's paper which are, 

 however, more matters of opinion than of fact, and may therefore 

 be merely mentioned for the guidance of future students of the tribe. 

 In the subgenus Irichroa; for instance, germari is more nearly re- 

 lated to guyoti than to andrczvsii; in Sphccroderiis, bicarinatus, steiio- 

 stomus and Iccontei are valid species; the. former varies indeed in 

 the development of the elytral carinre and is in that character ap- 

 proached by some examples of Iccontei, but it never loses the peculiar 

 parallel sided form, of which no examples of Iccontei present any 

 suggestion; the two latter are separable by any number of characters, 

 and, since their range is in part the same territory, it is impossible 

 to regard them as geographical races one of the other. 



In regard to Sphceroderus canadensis, it may be mentioned that 

 Mr. Blanchard in his letters points out that this species is repre- 

 sented in the White Mts. of New Hampshire as well as in the locali- 

 ties given by Dr. Roeschke, but by a race not identical with the typ- 

 ical form; the interstitial erect setce noted in the typical form are 

 lacking and the elytral striae are impunctate. This race was called 

 blanchardi in our correspondence and may be described as follows: 



Sphaeroderus canadensis subsp. blanchardi n. subsp. 



Similar to canadensis in size, form and color, but with the margins less 

 blue, the marginal and epipleural punctures less deep and coarse, the elytral 

 margin less strongly reflexed, the elytral striae almost impunctate, the first
