differ in form ; the fringes are unicolorous, and the abdomen is 

 narrower. The figure more nearly represents in fact a species 

 which I have received from Bahia, Brazil, and which differs from 

 xylina, though the larva (also quite different) feeds on cotton. 



We are all inclined to follow determinations of those who make 

 a specialty of any group, but after due allowance for faulty color- 

 ing in Hiibner's figure, I am constrained to believe that in this 

 instance Mr. Grote has been in fault. 



Pempelia GROSSULARL-^ Packard (Rep. I, p. 140) — The 

 European ZopJiodia convolutella Hiibn. {Phycis grossulariclla 

 Treitschke), which has precisely similar habits, closely resembles 

 this species. In 1871 I compared it with this last in Mr. Stain- 

 ton's collection and with specimens received from Prof. Zeller and 

 could detect no essential differences. The Luropean specimens 

 are slightly larger, with broader wings and usually clearer, paler 

 gray coloring. Colorational markings are, however, very variable 

 in specimens from both sides of the Atlantic. 



P. grossularice Packard was subsequently described by Grote 

 as Dakruma turbatella (Bull. U. S. Geol.-Geog. Survey, IV, No. 

 3, p. 702 ; 1878). Dakruma seems to differ from ZopJwdia in noth- 

 ing but the absence of the basal portion of the subcostal vein and 

 possibly, although this character is not mentioned by Grote, in 

 the recurved palpi. According to the synoptical table given by 

 Yi€vci&v(\zxiVL, grossiilaricB would fall in the genus Stcnoptycha, dis- 

 tinguished from ZopJiodia by the recurved palpi. We may well 

 question the generic value of this character, for different authors 

 describe it quite differently: thus, Heineman describes the palpi 

 of Stenoptycha and Hoineosonia as recurved, whereas Grote de- 

 scribes them as porrect in these two genera, if we accept his state- 

 ment tiiat Hoiiora Grote is to be considered a section of Stenop- 

 tycha : there appears also to be a difference in position in speci- 

 mens of the same species, according as the palpi are heavily 

 scaled or have lost the scales. From the known individual variation 

 in the venation of these and other moths, especially in the hind 

 wings, we cannot attach any specific, much less any generic, value 

 to the slight difference in the subcostal vein of Dakruma noted 

 above. Moreover, authentic specimens o{ grossularia; do not ap- 

 pear to possess this character of Dakruma. I am, therefore, of 

 opinion that a study of sufficient material from both continents 

 will prove the two specifically identical, or at the most that our 

 American insect is a variety, and that Dakruma will not obtain. 

 Packard is of this opinion, as in the later editions of his Guide 

 the species is called Myelois convohitella. 



Penthina VITIVORANA Packard (Rep. I, p. 133). — This is 

 identical with a European insect having the same habits. It was 

 first described over a century since by Schiffermiller & Denis as 

 Tortrix botrana, and has been referred to various genera since, 

 and finally to Eudemis Hiibn., so that the insect should be known
