 Clem, removed to Part>rn/'.r Spuler, on ( 'lemens description of the 

 venation. In regard to l>>,i-c(i*rll<i a word of explanation is re- 

 quired. ( 'lemens described the species from a single specimen 

 without a head and much mutilated, basing his determination 

 upon the neuration, as he says, almost exclusively. Although 

 he says it differs somewhat from the venation of species of Put or 

 sp. (Or nix Tr) then known to him, he was undoubtedly correct 

 in his determination. I would direct particular attention to his 

 description of the venation of the hindwings, which is as follows : 

 "In the hindwings the venation is the same as in other mem- 

 bers of the genus, except that the inosculation of the bifid sub- 

 costal vein with the tip of the costal, and of the lower branch of 

 the former with the furcate discal nervule, is almost obsolete and 

 very indistinct." 1 It will be noted that Clemens here has called 

 attention to the three branches of the costa, shown in the species 

 having the extra vein in the hindwing, mentioned at the begin- 

 ning of this paper. Dietz 2 the last one to revise the North 

 American species of Paronrix Spl. (Ornix Tr) says that he be- 

 lieves it to be? a true Ornix Tr. 



Spuler's genus Eutrichocnemis 3 was erected without a de- 

 scription of the> neuration and he places under it the two species 

 simploniella V. Rosl, and scalariella Zell. but does not specify 

 the type. As Walsingham made scalariella Zell. the type of his 

 genus Dialectica, I would propose, in order to simplify matters, to 

 consider scalariella Zell, as the type species and list Eutrichoc- 

 nemis as a synonym of Dialect ica. The genus represented by 

 these two names is placed provisionally under Acrocercops. One 

 species, onosmodiella Busck, corresponds more closely to Din- 

 led ica in venation than it does to Acrocercops, dii'feiing from the 

 former genus chiefly in that vein 2 of the forcwing is absent. 



It was believed that texanella Busck should be transferred from 

 Parectopa Clemens, to Parornix Spuler, which it most resembles 

 in venation. The venation is quite close to that of guitea Haw. 

 but in some respects it is an interesting species quite; different 

 from any other listed under this genus. The species axtericola 

 Frcy and Boll, quinquestrigella ('ham. and rhombiferellum Frev 

 and Boll, were transferred from Parectopa to Acroc< /<<>/>* on 

 external characters, following Meyrick's scheme. The species 

 salicifoliella Cham., was found to correspond closely with the
