COXINA.—XYLIS. 34] 
COXINA. 
Coxina, Guénée, Sp. gén. des Lép. vi. p. 297 (1852) ; Walker, Cat. xii. p. 867. 
Walker followed Guénée in placing Covina in the Eriopine; but it appears to me 
to be very much more closely allied to the genus Homoptera, and I therefore include 
it in the Homopterine. Coxina contains three representatives, all from Mexico or 
Central America. 
1. Coxina ensipalpis. 
Coxina ensipalpis, Guén. Sp. gén. des Lép. vi. p. 298, Noct. t. 14. f.5*; Walk. Cat. xii. p. 868°. 
Hab. Mexico! ?, Presidio (Forrer), Mexico city (Hége), Coatepec (Brooks), Atoyac in 
Vera Cruz, Teapa in Tabasco (H. H. Smith); Britisa Honpuras, Belize (Blancaneaua) ; 
GuaTEMALA, Volcan de Atitlan 2500 to 3500 feet, Pantaleon 1700 feet, Zapote, Capetillo, 
Panima in Vera Paz (Champion); Panama, near the city (J. J. Walker), Taboga Island 
(Mathew, mus. D.). 
This species is extremely variable in Mexico and Guatemala, where it is very 
common. Mr. Smith’s examples were captured between the months of February and 
April. 
2. Coxina minax. 
Corina minax, Guén. Sp. gén. des Lép. vi. p. 298°; Walk. Cat. xii, p. 868”. 
Hab. Mexico, Yucatan ! 2. 
3. Coxina hadenoides. 
Corina hadenoides, Guén. Sp. gén. des Lép. vi. p. 299’; Walk. Cat. xii. p. 868 *. 
Hab. Mexico 1 2, 
Mons. Oberthiir informs me that Guénée’s type of this and of the preceding species 
cannot be found. It is most probable that they are only varieties of C. ensipalpis. 
XYLIS. 
Xylis, Guénée, Sp. gén. des Lép. vii. p. 7 (1852) ; Walker, Cat. xii. p. 1051. 
A single species only, from Brazil, was included by Guénée in this genus ; it appears 
to me to be very closely allied to Homoptera, but to have the primaries slightly longer. 
Homoptera ustipennis, Walk., from an unknown locality, as noted by Butler (cf. Trans. 
Ent. Soc. Lond. 1879, p. 41), isa Xylis; this insect, as well as X. setipes, is now known 
to inhabit Central America. 
1. Xylis setipes. 
Xylis setipes, Guén. Sp. gén. des Lép. vii. p. 7, Noct. t. 15. f. 61; Walk. Cat. xiii. p. 1052’; 
Herr.-Schiff. Corr.-Blatt zool.-min. Ver. Regensb. 1868, p. 191 (sep. copy, p. 29) °*.
