Ringe, über der Mitte der letzteren, eine seichte, mehr oder weniger 

 deutliche, kurze Längsfurche wahrnehmbar ist. Die Unterschiede ent- 

 sprechen der verschiedenen Lage der Fortpflanzungsorgane bei den 

 beiden Geschlechtern«. It is sufficient to say that Wilde like E.atze- 

 burg did not recognise the proper number of abdominal somites, and 

 the position of the male aperture in the penultimate somite; and judg- 

 ing from his words alone, he appears to have known and that not in 

 its full detail, only the Heteroceran type in which the two female aper- 

 tures are usually confluent. 



I may be permitted, perhaps, to make a slight correction in the 

 account given in my previous paper, of the azygos oviduct so far as 

 relates to one particular point. A renewed examination of the speci- 

 mens has convinced me that the second pair of larval vesicles, the pair 

 that is to say, which developes in the ninth somite, has a twofold 

 fate. The dorsal portion of the vesicles is converted into the sebaceous 

 apparatus, the ventral portion constitutes the posterior extremity of 

 the azygos oviduct itself, and where the ventral portion closes by the 

 fusion of the opposing lips of the aperture, the future oviducal aper- 

 ture is left at a spot which corresponds to the anterior extremity of the 

 second pair of vesicles, where they pass over into the primitive ovi- 

 ducal furrow.

On p. 622, No. 322 of the Anzeiger, Prof. Jackson states that 

 the fact that the sex of a given chrysalis can be determined has appa- 

 rently escaped the notice of all observers. 



This statement is not quite correct, for in a paper »Die Weiß- 

 tann entrieb wickler etc.« by Fritz A. Wachtl, published in 1882 at 

 Vienna by Georg Paul F a es y , colored drawings of the pupae of both 

 sexes of several species of Tortricidae are given. I am certain that the 

 fact of the diff"erences in the pupae has been noted by other writers 

 also, but I am unable to give the references, at this writing.
