 the margin. Subterminal line even, pale, near the margin. On s. t. 

 field two or three costal black dots and a black line above internal 

 angle. A black dash on internal margin near the base. Hind wings 

 fuscous gray, with two exterior pale lines. Body gray. The median

 median black patches are unequal in size and shape. 



Pyrrhia Hubner. 



Dr. Speyer is with myself of opinion that this is a valid genus, the 

 species differing decidedly from Chariclea, in vestiture and armature. 

 While there is but one European species, we have three from the terri- 

 ritory east of the Eocky Mountains. These are: Uxprimens Walker 

 (Bull. B. S. ]Sr. S. II, pi. Ill, fig. 5), which seems to stand nearest the 

 European form; Angulata Grote {id. loc. fig. 6), which has been com- 

 paratively described by Dr. Speyer under the name of "ExiJrimens"; 

 and Sticla Grote (ISTorth American Entomologist I, 45), which is the 

 largest, handsomest, and most intensely colored. The pattern of orna- 

 mentation is the same in all four forms, while our two species of 

 Chariclea, Triangulifera, and Peruana, have a very different style of 

 marking and exactly follow the European type of the genus, DelpMnii. 



EXJLINTNERIA n. g. 



The neuration is given. Trans. Am. Ent. Soc, 1872, 106. Male with 

 a cut in the primary wing on outer margin; female with entire wings. 

 Male antennse simple, ciliate; palpi three times as long as the "front," 

 curved upwards. Ocelli present. ''Front" flat. Eyes naked and legs 

 unarmed, as always in the Deltoids. Professor Lintner suggests that 

 our species does not belong to Tortricodes, and, in this opinion, I name 

 the genus for him. Type : Tortricodes bifidalis Grote. 



Geometridw. 



EUCATERVA VARIARIA GrotC. 



This geometrid genus and species, which I have elsewhere character- 

 ized, I again call attention to on account of the difference in the length 

 of the male and female labial x)alpi. In both sexes they are longer than 

 usual in the group, in the male, longer, curved, projecting upwards and 

 forwards, linear, closely scaled, ringed black and white. In the female, 

 similar in appearance, shorter, pointed, and perhaps slenderer. The 

 body is rather stout ; the female abdomen thick and vermiform. The 

 species seems to be allied to Caterva catenaria, a species I am unwilling 

 to refer to Zerene, but which Dr. Packard has characterized under this
