coidal veins are close together; the third obsolete at base, emits the 
fork about midway its length (counting to the imaginary point of in¬ 
sertion). No honey-tubes; the abdomen expanding near the tip.

The wingless individuals are very short, broadly ovate, and very 
convex; olive green, covered slightly with a w T hite powder; antennae 
and legs very short. 
Mr. Mon ell calls attention to the errors in the bibliography of this 
species, in his article in the Canadian Entomologist , as foilow r s: “The 
bibliography of this species really seem, like a ‘Comedy of Errors. 
Dr. Fitch placed it in a wrong genus; Mr. Walsh removed it to 
Thelaxes , and refers to N. Y. Rep., I, 257, instead of I, 357, I he 
American Entomologist omits to index it for p. 224. Mr. Packard 
(Guide, p. 525), mentions Thelaxes ulmicola' Walsh, while on the next, 
page he speaks of Pemphigus ulmicola , (Fitch), and refers to figure 
525, which is from an electrotype of the identical woodcut first pub¬ 
lished by Messrs. Walsh and‘Riley, in the American Entomologist , 
under the name Thelaxes ulmicola , Fitch. Mr. Packard’s figure 525 is, 
therefore, my C r . ulmicola , and, indeed, I have so far failed to find 
any other mention of Pemphigus ulmicola, Fitch. ’ But the writer is 
mistaken, in saying that it is not indexed for page 224, in the Amer¬ 
ican Entomologist , as it is indexed for this page, under “Cockscomb 
elm-aall.” and “ Thelaxes ulmicola.” t
