NOMENCLATIEE. 



Lord Walsingham, in the paragraph cited above, states that 

 Packard's species geminaiella undoubtedly belongs to the genus 

 Ornix, and that the type specimens then before him were proba- 

 bly the same as O. prunivorella, — a probability which would have 

 doubtless been greatly strengthened in his mind had he not been 

 under the erroneous impression that the latter species had never 

 been bred from apple. Dr. Packard's figures agree very well with 

 ■Chambers's description and with the excellent descriptions and 

 figures of Mr. Brunn, as well as with specimens collected and bred 

 by the writer. 



In order to be as certain as possible of the identity of the two 

 species I sent specimens of larvae which, without doubt, belonged 

 to the species described by Chambers as prunivorella to Dr. 

 Packard with the request that he examine them to see if they 

 were similar to the ones from which he bred L. geminaiella. In 

 response he writes as follows, under date of December 15, 1886: 

 "I have examined the Ornix prunivorella — two larvae — white, ex- 

 actly of the size and shape of my geminaiella, which I have not 

 :seen for nearly twenty years. Mine was a uniformly brown cater- 

 pillar, but the spots on prothoracic segment were not as distinct 

 as appears in your specimen, yet in my figure I see they are 

 represented I suppose the alcohol brings out the tubercles more 

 distinctly than in life. It may be safe to regard the two species 

 as the same, since Chambers bred it from the apple. On turning 

 to Emerton's original drawing I see the spots on the thorax are 

 represented just 'as in your specimen. My description on the 

 sketch says: 'Color pale livid reddish, suspended by a thread to 

 the tree.' On the whole, then, I conclude that the larvae you send 

 Are those I described as L. geminaiella.'' 



The difference in the colors of these different larvae may easily 

 be accounted for on the supposition that Dr. Packard's specimen 

 was not full grown, for, as has been remarked by Mr. Brunn, 

 these larvae are flesh-colored wlien young. 



In the light of these various observations, the writer believes 

 that he is justified in treating these supposed species as the 

 same; and, as Dr. Packard's name has priority, in calling the in- 

 sect Ornix geminaiella^ Packard. 



DESCRIPTION. 



Mr. Brunn has so carefully described the two earlier stages of 

 ihis insect that I cannot do better than to quote his description in 

 full. 



"Larva.— When full grown 6. 8 mm. (.27 in.) in length. Color 

 grayish; when young flesh colored. Head light brown and about 

 •one half as broad as the first thoi-acic segment, which is light yel- 

 low. Form cylindrical with the last three or four segments of
