THE CANADIAN ENTOMOLOGIST. 407 



be confounded with it, except by pure perversity. This error on the part 

 of Mr. Leng, which is the most unaccountable that I can recall having 

 seen in print, and, I understand, not typographic, as I had at first sup- 

 posed, naturally engenders a suspicion that this author must needs have a 

 very inconstant and peculiar personal equation in regard to reliability. 



N'eotnysia^ Csy. 

 Although the American and European species are probably con- 

 generic, our European colleagues do not seem to have discovered that the 

 name Mysia was long since preoccupied when imposed by Mulsant. The 

 name Neomysia has therefore to be used for the species of both continents. 

 Crotch, who had probably seen the type, states that siibvittata, Muls., has 

 the elytra broadly dilated at the sides, which makes it very doubtfully a 

 species of N'eoniysia, where it is placed by Leng, but more probably an 

 Anatis, to which genus it is assigned by Crotch. The synonymy proposed 

 by Mr. Leng is therefore erroneous. The assignment of interrupta to 

 Ho7'ni as a variety is, moreover, an error almost as flagrant as that noticed 

 above under Anatis LeContei ; the two are evidently distinct species* 

 Horni being the smaller and much less broadly rounded, irrespective of 

 differences in ornamentation. 



Psyllobora^ Chev. 

 Of the described forms in this genus, 20-maculata, reni/er, borealis, 

 tcedata, deficiens and najia are true and valid species ; obsoleta may be 

 considered a synonym oi 20-maculata and parvinotata as a subspecies; 

 separata may be regarded as a subspecies of tcedata. 



Tribe Exoplectrini. 

 This tribe, including such genera as Rodolia, Vedalia, Novius and 

 Exoplectra^ with rounded form, pubescent surface and wide, externally 

 descending epipleura, should be interpolated in the table of tribes given 

 in my Revision immediately after Epilachnini. 



The genus Neaporia, of Gorham, is certainly composite and, as no 

 type was named, I would propose metallica^ Gorh., as the type. Plagio- 

 derina, Gorh., evidently forms another genus, much more broadly 

 orbicular, for which the name Atieaporia (n. gen.) may be suggested. 

 Indagator, together possibly with compta, probably forms another genus. 

 Some important generic characters doubtless exist in antennal and 

 sternal structure, to which Mr. Gorham makes little or no reference.
