collection, without indication of its original source, and I am by no 

 means ready to vouch for the locality ; and yet Long Island might 

 not be an improbable point of occurrence, and southern New Jersey 

 is still more likely to produce it. 



There is very little range of variation in the examples before me. 

 There is a little difference in tlie shade of brown, due somewhat to 

 age and condition and some difference in the distinctness of the me- 

 dian lines; but otlierwise they all look very much alike. 



In the secondary characters of the male the species is in general 

 accord with the others of its section, save that the wing tufts of the 

 under side are much less marked than described for incusalis, which 

 in this respect is selected to illustrate the character; that on vein 5 

 of the secondaries is practically absent, and on the primaries the 

 clothing is scarcely more prominent than in some species of the later 

 section. The tuft from the costal area of secondaries is distinct and 

 like that of incusalis, but smaller. The structure of the median 

 tibiae is like incusalis, though when examined on the set specimen 

 they seem only a little thickened and set with flat covering scales, 

 which in fact conceal the tuft and excavation. 



The abdominal tufting is characteristic and is figured for the 

 series from this species. There is really a typical stalked pencil tuft 

 concealed in an abdominal groove and a covering tuft attached at 

 the sides of the first abdominal segment, and bent over so as to 

 shield as well as conceal the groove containing the hair pencil. The 

 covering tuft is re in forced by a membraneous shield inwardly, and 

 it is completely to be moved aside to give freedom to the hair pen- 

 cil. The first ventral (second actual) segment of the abdomen is a 

 shield-like plate, and under its edges the stalk which carries the 

 pencil is inserted. 



Tlie antennse of the male are ciliated, and the several joints have 

 lateral, longer cilise. 



Pleoneotyptera reversalis u. sp. 



Ground color greenish-gray ; of primaries a little paler than of head and thorax. 

 Maculation olivaceous. T. a. line rigid, inwardly oblique, well defined toward 

 base, broad, outwardly diffuse. T. p. line yellowish, obscure, preceded by an 

 olivaceous shade line which is inwardly diffuse; in course a little outcurved over 

 cell, and very slightly incurved below. S. t. line broken, but scarcely puncti- 

 form ; there are two dusky spots below the apex and then from vein 7 the line 

 is continuous, bisinuate, hardly relieved against the s. t. space which is dusky to 

 vein 6 from inner margin, but clearly defined against the terminal space which
