1 70 ENTOMOLOGICAL NEWS. [May, 



in Mrs. Slosson's collection, the Cuban moth is much larger, the body be- 

 ing twice as thick, while the antennae have shorter pectinations ; also the 

 palpi are larger and project farther in front. The shape of the head and 

 front is the same in both. The fore wings are entirely white at base of 

 costa above and beneath, where in E. slossonicz it is brown. There are 

 brown hairs on the breast, as in the other species. The fore legs are 

 nearly white, much more so than in E. slossonics. In its venation E. ni- 

 valis differs from the Floridan species as follows : Fore wings, the second 

 subcostal branch arises much nearer the anterior discal vein, only one- 

 third the way to the origin of the third subcostal branch, the distance be- 

 tween the origin of the second and third being twice as great as in E. 

 slossoniiz. There are also slight differences in the direction of the an- 

 terior discal vein, and in the distance between the origins of the first and 

 second median venules. In the hind wings the first and second subcostal 

 divide at the origin of the upper discal ; in E. slossonia: they divide far 

 beyond the origin of the upper discal and one-third the way out to the apex 

 of the wing. The direction of the two discal venules differ, these being more 

 oblique in the Cuban species. Length of fore wing 14 mm. ; of body 12 mm.

NOTES ON ICHTHYURA Hub. (Melalopha Hiib.) 

 By HARRISON G. DYAR, Roxbury, Mass. 



Mr. Neumoegen and myself have reached conclusions in re- 

 gard to the species of Ichthyura very similar to those set forth by 

 Dr. Packard in the March number of the NEWS. There are several 

 differences in our conclusions, which I would like to notice. Ich- 

 thyura inornata Neum. We give this form specific rank. In 

 markings it does not differ from / van var. ornata, but the large 

 size and absence of the thoracic patch entitle it to more than the 

 rank of a local race. While I believe that Dr. Packard is right 

 in considering such forms as luculenta and ornata as local races, 

 I think he has carried this idea too far in the present instance. 



Ichthyiira jocosa Hy. Edw. We give this specific rank also. 

 Only the types are known and differ from indusa in the absence 

 of the silvery part of the outer line. It may prove to be a race 

 of indusa but it seems premature to so refer it now. 



Ichthyura bifiria Hy. Edw. I cannot at all agree with Dr. 

 Packard in his reference of this form. It is not allied to / brucei 

 but on the contrary is close to /. vau, and is probably the local 

 race of it inhabiting the Sierra Nevada of California. I have 

 bred the larva, and the description appeared in these pages in 

 January, 1892.
