CRYPTOLECHIA. 



In the Can. Ent. iv. 120, I have attempted to define a new genus 

 under the name of Hagno, and in that connection have alluded to its 

 resemblance to Psilocorsis Clem., which was known to me only by Dr. 

 Clemeus's writings, not having seen any of his species. The wings of 

 Psilocorsis, as described by Dr. Clemens, seemed to me to differ mate- 

 rially from those of Hagno. 1 also suggested the probability that both 

 might prove to be equivalent to Cryptolechia, which was then known to 

 me only by scattered notices in various books. I find that Hagno is 

 equivalent to Psilocorsis, and both are equivalent to a section of Cryp- 

 tolechia. 



C. CRYPTOLECIIIiEELLA. 



Depressaria? cryptoIecMceella, Cham. Can. Eut. iv. 91. 

 Hagno crijptohdnmtUa, Cham. ibid. 132. 



Smaller and prettier thau any of the allied species known to me. The 

 wings have a faint pinkish or roseate lustre, and have the lustre also of 

 "watered silk". The transverse blackish lines are not visible to the 

 naked eye ; and the base of the wings is orange-yellow. If my recol- 

 lection is not at fault, the larva feeds on leaves of the Holly {Ilex). 



C. FAGINELLA. 



Hagno fayinella, Cham. Can. Ent. iv. 131. 



The close resemblance of some allied species makes a more detailed 

 description of this species than that heretofore given necessary. 



The palpi are ochreous, with a blackish line along the under surface 

 of the second joint, continued on to the apex of the third, and another 

 on the outer aud one on the inner surface of the third joint. Cryptolechia 

 (Psilocorsis) quercicella Clem., according to Dr. Clemens, has the third 

 joint black, with two yellowish-white stripes in front. I, however, have 

 not seen the species, and I know from experience how easy it is to 

 make a mistake as to the number aud position of these lines. A species 

 from Texas which I formerly (Can. Ent. vi. 231) identified with fagi 

 nella, but which 1 now consider distinct (vid. post), and an undescribed 

 species, of which a single specimen is before me, have the palpi exactly 

 as I have described them in faginella — that is, the upper surface of the 

 third joint is ochreous instead of black, as Dr. Clemens's account would 

 make it. C. faginella has the head ochreous-yellow, and the thorax of the 

 same color, only darker, as if tinged with fuscous. In this, the Texan 

 species agrees with it. The undescribed species above mentioned, which 

 is from Missouri, and has been bred by Professor Eiley and Miss Murt- 

 feldt from a larva feeding on Ambrosia has the head darker than in fagi- 

 nella, and of the same color with the thorax. C. quercicella, according to 

 Dr. Clemens, has the head and thorax yellowish-brown (as in the Mis- 

 souri specimen). P. reflexa, as described by Dr. Clemens, has the palpi 

 as in faginella as to ornamentation; but from the fact that Dr. Clemens
