shade spot ; the markings are continuous over hind wings at 

 base ; the large white subterminal field is sprinkled with brown 

 scales; the terminal band is velvety black enclosing four or five 

 gilt points ; the edge of the wing is ochery, obtaining at apices; 

 black scales extend from the terminal band beyond the gilt 

 points, interrupting the ochre edging of the wing ; beneath with 

 the markings more faintly repeated ; tegulae striped with white. 

 Expanse 12 mil., Carbondale, Illinois, Prof. French, in July. 

 Smaller than Lederer's opidentalis, with very different second- 

 aries. The ocelli are present. 



Cataclysta HELOPALIS, Clemens, P. A. N. S. Phil., 217, 

 i860. 



I have identified this species from specimens (N. Y.) in my 

 collection. As stated by Clemens it differs from C. Fiilicalis in 

 having ocelli. In ornamentation and general appearance it is 

 very like that species. It is a little larger, paler, with narrower 

 inner line on secondaries, and there are a few obscure metallic 

 points on the lower half of the external border on primaries. 

 With this the small form C. Medicinalis agrees in having ocelli ; 

 but I can refer neither to the allied genera having ocelli. I have 

 examined C. Fiilicalis Clem., C. Angulatalis Led.(?) and C. Bifas- 

 cialis Rob., in my collection, in all of which the ocelli are absent. 

 These species may be arranged as follows. The neuration ap- 

 pears to differ in all the species.

Group B, without ocelli, Cataclysta Hub.

Angulatalis Led., Kaden in lit., 486, No. 132. 



Bifascialis Robinson, Ann., N. Y. Lye. N. H. Vol. ix. 154, PI. i, 

 fig. 4. 

 I have not yet met with specimens of C. Opulentalis Led. 

 Taf. 18, fig. 7 (which cannot be Fulicalis) or Moniligeralis Led., 

 Taf. 18, fig 10. It is also not known to me under what names 

 our species stand in the British Museum collection. The genera 

 Dicymolomia {Decora Zell., from Texas, and either the same or an 

 allied form from California) and Chalcoela {Aurifera Zell., and 

 Robinsonii Gr.) belonging to our fauna, have also gilded dots on 

 external margin of secondaries, but are structurally quite distinct 

 from Cataclysta. 



The following three described species of Hydrocainpa are 

 in my collection ; the ocelli are present in all three forms.
