not identical insects. They have, of course, nothing to do with the genus Metagansta, 

 and agree with none of the present genera of Agaristidae, and will require a genus of 

 their own. Thev differ structurally from Copidryas G. & R., to which' genus they 

 come nearest, in the forehead bearing a short conical processus with circular ridge 

 and being narrower than the eyes are high (when viewed from front side), and in the 

 second partition of the median nervuro to the hindwings being shorter than the lower 

 discocellular veinlet. In the male of sahidosa Feld. and noctidfoi-mia ^loschl. the 

 forehead is narrowed behind as in Aegocera trimeni Feld. and allies. K. J.

We have two fenvde specimens (from ^'enezuela and Hiitish Guiana) of an 

 Agaristid which is ajjparently the same as Diamuna severa (StoU), Pajj. Ex. IV. 

 p. 2:10. t. 398. f. I (1782) (Surinam^, though they have not the peculiar patch on the 

 forewings as shown in HtoU's figure. They exhibit the following structural characters 

 which I think necessary to point out, as N\'alker's diagnosis of Diamiina is a very 

 vague one : — 



? . I'ront of the head a half narrower than the large eye (when viewed from the 

 front side) is high, conically produced, with a sharp sulicircular ridge. Palpi stronglv 

 hairy, terminal joint scarcely longer than broad. Antennae almost filiform, not 

 reaching apex of cell to forewings ; dilatation towards apex scarcely noticeable. All 

 the tibiae strongly hairy. 



Neuration : similar to that of Phasis \\'lk., but second partition, of median 

 nervure to forewings half as long again as the respective portion of the outer margin ; 

 same partition to hindwings longer than lower discocellular veinlet. A^ein 7 to hind- 

 wings, though touching 8, distinctly separate from 8 bv a furrow, its basal partition 

 thicker than in Pliusis Wlk. and most other Agaristids. 



Differs from Phasis Wlk., to which Diamuna Wlk. comes nearest, in the thin 

 antennae, the narrower forehead, the larger ey-es, the longer second partition of the 

 median nervure to either wing, the hairv middle and hind tibiae, and in vein 7 to 

 the hindwings being thicker at base and being separate from 8 by a furrow when 

 touching it. K. J.

A (J specimen without locality in the Felder collection agrees fairly well with 

 St oil's figure of Clilis proserphm {HoW), Pap. Ex. IV. p. 239. t. 399. f i (1782) 

 (Surinam). It has the short and thin antennae of Diamuna Wlk., and is similar to 

 that genus in the form of head and eyes, and in the long second partition of the 

 median nervuro : but vein 7 of the hindwings is confluent for about 1 millimetre 

 with vein 8 beyond the basal third of the cell; thebasal partition of vein 7 is well 

 developed. 



In the narrow forewings and broad hindwings Clitis proserpina (Stoll) reminds 

 one of Hecatesia falcata Druce. Tlie underside of the abdomen is in our cJ specimen 

 clothed along either .side with long hairlike scales, which are broadest at the tips, 

 and being turned over the middle of the abdomen give the underside of the latter a 

 strongly woolly appearance. The hindwings are furnished above at the basal portion 

 of the costal margin with long hairs, covered l>y the abdnniinal margin of the
