A free translation of the original description of hrennus follows: 



"Wings fuscous-brown almost immaculate; sparsely scattered 

 with yellow scales; anteriors with a hardly paler submarginal 

 l)and, without hyaline spots; palpi below with blackish and 

 yellow scales intermix(;d with the long vestiture." 



The insect was not figured, but the name is fixed by the 

 description and the figure of the genitalia. We figure the geni- 

 talia of both brennus and imbros. 



Tiie uncus of hrennus ends in a single slender projeittion, and 

 itself is incised on each side; the scaphium is scarcely developed; 

 the ventral lobe of the valve terminates in a cordate section 

 overlapping the ventral portion, rounded apically and serrate 

 on its outer ridge; the aedoeagus is slender, carrying internally 

 a few small spines. 



Record: Mexico, Texola, Vera Cruz. 



23. Systasea pulverulenta Fekler (Fig. 23.) 



This species has the costal fold. A fluted or incised margin 

 to the secondaries is characteristic of the genus.

Staph ijlus 'i/«&ras was described by Godman and Salvin, (Biol. Cent.-Anier., 

 Rhopalocera, p. 435, i)l. 89, figs, 27 [o^j 29 [9], (1897)), from a considerable 

 sories from Mexico and Guatemala, the type presumably from Misantla, 

 Mexico (first named locality). A free translation of the original Latin des- 

 crijition follows. 



"Wings deeply fuscous-brown with an obscure band hardly noticeable; 

 anteriors without subapical hyaline spots id')', palpi below ochraceous yellow 

 scales intermixed with blackish. 



" 9 similar, but larger, the obscure band larger, obvious and anteriorly 

 supplied with three subapical hyaline spots." 



They further state it is exceedingly like hrennus, but has rather less prom- 

 inent joints to the palpi. Our specimens further show a greater expanse for 

 imbras namely, 16 mm., from thorax to apex of wing against 14 nun. for 

 hrennus, hayhurstii and ascalaphus. 



The uncus ends in a stout bulbous process, there are incisions on eatsh 

 side of the uncus; the ventral lobe of the valve, rounded apically, projects 

 beyond the discal lobe and where they meet the chitin of both is convoluted; 

 tlie aedoeagus is simple, somewhat bent in the middle.
