4i 6 MEMOIRS ON THE COLEOPTERA 



in no sense a variety of any other. The name was misprinted 

 " salicola," but, although noticing the error shortly after publi- 

 cation, I have neglected until the present opportunity, to change 

 it to the correct form salicicola. 



It is possible that Tetraopes vegasensis Csy. (1. c., p. 380), may 

 be the same as collaris Horn. Although an inspection .of the type 

 of the latter some time ago, at any rate shows a rather close gen- 

 eral agreement, I could form no absolutely determinative conclusion 

 except by having the two forms together; meanwhile it might be 

 considered as subspecifically related to collaris. 



Anthophilax viridis Lee., from Eagle Harbor, Lake Superior, is 

 said to have the head and prothorax virescent, the antennae paler 

 toward tip and the tibiae rufescent toward base. The form from 

 the Adirondacks, which we have been calling viridis, has the head 

 and prothorax of a subcupreous chocolate-brown and the elytra 

 bright green as in viridis and similarly sculptured, but the antennae 

 are not paler apically in either sex, being entirely black (cf 1 ), or 

 with the joints beyond the second entirely pale, with black tips 

 (9); the legs in the male are entirely black; in the female they 

 are colored as described of viridis. This Adirondack form seems to 

 be at least varietally distinct from viridis, and I would propose for 

 it the name Anthophilax viridis ssp. viridipennis nov. In the 

 Lake Superior cyanens Hald., the entire upper surface is green, the 

 antennal joints (9) particolored, and the legs in that sex are en- 

 tirely pale, with darker knees and tarsi, the elytral sculpture less 

 dense than in viridis or viridipennis; it is apparently a valid species, 

 differing from malachiticus in its larger size, stouter form and much 

 finer and sparser terminal sculpture of the elytra. 



The Lake Superior form of Centrodera decolorata differs from the 

 eastern form in having more cuneiform and basally broader elytra 

 in both sexes, and a relatively smaller and more densely punctate 

 head. This may be seen very readily in series. The Lake Superior 

 form may be called Centrodera decolorata ssp. lacustris nov.
