any poiut so far north as Pliiladelphia, from wliicli one of Mr. Grote's 

 specimens is credited. 



The male auteuua^ have the pectinations well marked and laterally 

 ciliated, furnished near tip with a long bristle, and toward the apex the 

 branches become clavate or somewhat enlarged, clnblike. At one-third 

 from base a single joint is inwardly furnished with a single corneous 

 X)rocess, accompanied by a stiff bristle, and in all essentials the member 

 agrees with the genus to which it is referred. 



The anterior leg of the male is hke tliat of Litophora., save that there 

 are no tuftings. The sensitive space on the under side of the femur is 

 more protuberant, rounded, and fits quite closely against the tibial 

 epiphysis, which in turn fits into the greatly developed tibial process, 

 forming an oval mass beyond which the four rudimentary tarsal joints 

 project. In this oval mass are concealed the s])ecialized scales which 

 nowhere develop into pencils of hair. 



Except for the wing form, this sjjecies agrees in all its essential fea- 

 tures with the other species of the genus to which I have referred it. 

 The apices here are usually as distinctly rounded as they are pointed, 

 or at least rectangular, in the other forms; but the difference is hardly 

 greater than that found among the species of ZancJofpiatlia, and I have 

 not deemed it well to disassociate it. The palpi show a tendency to 

 an ui)right scaling of the upper edge; but not more marked than in 

 some specimens of H. absorptalis. 



Professor French's type of Pallachira hart'n I have seen by the 

 courtesy of Professor Forbes. It is typical //. orciferalis and agrees 

 fully with Mr. Grote's description ot'mi\\elI.piii)iU((ri.s. Professor French 

 allowed the obvious resemblance to FnUachlra bivittata to delude him 

 into the belief that it could not have been described under another 

 generic name. 



Genus PHILOMETRA, Grote. 



1872. Grotc, Traus. Am. Eutomological Soc, IV, 99. 

 Eyes naked, large, globose. Front smooth, in perfect specimens with 

 a pointed tuft between the antenna\ Tongue moderate. Antennae 

 long, arising from the vertex close to the compound eye, the basal joint 

 somewhat enlarged m the male. In the male the antcniub are lengthily 

 bipectinated in their entire extent, the branches slender and setose, and 

 there is no special modification. In the female the anteuuic are shorter, 

 simple or sparsely ciliated. Oc^elli distinct, close to the compound eye, 

 well removed from the base of the antenn.e in F. ctivteliisalis, (]uite 

 closely approximated in i'. metonalis. Palpi long, the second joint much 

 ,the longest, clothed with upright scales above and on the side, forming 

 a sharp ridge which m P. metonalis is equal and continuous, l)ut in 

 P. cHmt'IusdJis IS more prominent centrally. In the former the palpi 

 are directed straight lorward, the terminal joints diverging at tip, 

 while in the latter they diverge from the base and aie curved obli(iuely
