Phacusa, Stal, Stett. ent. Zeit. 1864, p. 72; Ofv. Kongl. Vet.-Ak. Férh. xxvi. p. 247 (1869). 
This genus was formed by Stal to inciude one or two species closely allied to 
Acutalis, but larger and more elongate than the average representatives of the latter 
genus, and chiefly distinguished by the fact that the tegmina have one discoidal area ; 
as in Acutalis, the tegmina and the wings have five and four apical areas respectively. 
Stal has described two species, and three more are here added, all being from Central 
America. 
1. Phacusa flavo-marginata. (Tab. VII. figg. 19, 19a.) 
Phacusa flavo-marginata, Stal, Stett. ent. Zeit. 1864, p. 72°. 
Hab. Mexico (coll. Signoret}, in Mus. Vind. Ces.). 
One very imperfect example. This species appears to be a well-marked and distinct 
one, and may be easily known by the colour of the pronotum and the black base of 
the tegmina. | 
2. Phacusa pallescens. 
Phacusa pallescens, Stal, Ofy. Kongl. Vet.-Ak. Férh. xxvi. p. 2471. 
Hab. Mexico (coll. Signoret!, in Mus. Vind. Ces.). 
This is a small pale testaceous species, of about the same size and appearance as a 
pale specimen of Acutalis fusco-nervosa, from which it may at once be distinguished 
by the neuration of the teg mina. 
8. Phacusa major, sp.n. (Tab. VII. figg. 20, 20a.) 
Elongata, nitida, unicolor, olivacea vel testacea: P. pallescenti maxime affinis, sed multo major, antice latior, 
humerisque magis prominulis. 
Much larger and broader than P. pallescens, to which it is closely allied, and with the shoulders more promi- 
nent ; the tegmina are entirely hyaline or slightly infuscate towards the apex. 
Long. 9 millim.; lat. int. hum. 4 millim. . 
Hab. GuatEMALA, Volcan de Agua 8500 to 10,500 feet, San Gerdénimo 3000 feet 
(Champion). . 
The two specimens from San Gerdénimo are more distinctly punctured and have the 
tegmina slightly infuscate towards the apex; they can hardly, however, be regarded as 
distinct, and may perhaps be a connecting-link between P. major and P. pallescens. 
We figure a specimen from the Volcan de Agua. 
4. Phacusa variata, sp. n. 
Preecedenti affinis, sed minor, dilute testacea, capite pallido notis quibusdam obscurioribus nonnunquam 
ornato, pronoto antice et apice ejusdem vel spatio ante apicem late castaneo; pedibus rufo-testaceis ; 
tegminibus hyalinis, vitté ante apicem plus minusve distincta, interdum fere deficiente, notatis.
