4. Systasea emorsa. (Tab. LXXXVIL figg. 22, 23.)

Alis albidis ; anticis basi, apice et margine externo late fuseis cano atomatis et fusco indistincte notatis, area 

 mediana lineis angustis irregularibus transfasciata, maculis tribus subapicalibus, tribus ad medium costae, 

 una cellulari et duabus ultra earn semibyalinis ; posticis basi et margine externo fuseis, bujus dimidio 

 anali cano atomato, area mediana transversim lineata : subtus albis extrorsum oehraceo tinctis, lineis

Eab. Mexico, Pinos Altos in Chihuahua (Buchan-Eepbum), Cuernavaca (mus. 

 Felder l ), Chilpancingo (E. E. Smith). 



Mr. Buchan-Hepburn obtained several specimens of this species in Chihuahua, all 

 of them in poor condition ; but a single male captured by Mr. Smith at Chilpancingo 

 in August is uninjured. The latter agrees with Felder's description of the type in his 

 collection, which came from Cuernavaca in Morelos 1 S the bordering State to Guerrero. 



5. Systasea pulverulenta. (Tab. LXXXVIL figg. 24, 25.) 



Leucochitonea pulverulent a, R. Feld. Verh. z.-b. Ges. Wien, ]869, p. 478 \

Alis rufescenti-brunneis, stria anteciliari albida, ciliis canis fusco interruptis ; anticis basi, plaga ultra cellulam, 

 apice et margine externo fusco nebulosis, macula duplici infra ramum medianum ad basin, fascia trans- 

 versa irregulari per cellulam extrorsum indentata et punctis tribus ad apicem hyalinis ; posticis fusco 

 nebulosis, linea albida discali squamis fuseis subobscurata : subtus albicantibus, triente distali ocbracea, 

 bitriente basali fusco irregulariter nebulosa ; palpis (articulo terminali nigro excepto) et corpore toto 

 subtus albis, penicillo tibiali fulvo. 



Eab. Nobth America, Arizona (E. W. Henshaw 2 ). — Mexico, near Durango city 

 (Becker), Venta de Zopilote (H. H. Smith), Orizaba (Hedemann \ II. J. Ulwes), 

 Einconada (W. Schaus), Cordova (Bwneli), Atoyac (H. II. Smith), Valladolid in 

 Yucatan (Gaumer); Guatemala, Duenas, San Geronimo (Champion). 



This species, though very differently coloured to 8. erosa and S. funebris, seems 

 strictly congeneric, and, like them, has a costal fold to the primaries. 



Mr. Smith and Mr. Schaus captured several specimens of this species in Vera Cruz, 

 and these agree with Felder's description, and also with an Arizona specimen sent us 

 by Morrison with the name H. zampa attached to it. 



DI^US, gen. nov. 



A genus containing two or three small species, the affinities of which are rather 

 obscure, but which may for the present be placed here. 



The antennae are much as in the neighbouring genera : the terminal joint of the 

 palpi is rather prominent and porrect, more so than in Onenses, which follows ; and the
