ACONTIA.—-DACIRA. 309. 
Mr. Smith’s Atoyac specimens are labelled as having been captured in the month of 
April. 
15. Acontia cratina, sp.n. (Tab. XXVIII. fig. 26.) 
Primaries pale greyish-brown, becoming much darker near the outer margin, with a large black mark near 
the apex (like an inverted C), edged with a narrow white line, and a dark brown streak near the base 
extending across the wing from the costal margin, but not reaching the inner margin; secondaries dark 
brown, becoming paler near the base, the fringe very pale brown; the underside of the primaries very 
dark brown, palest along the costal margin and at the apex, that of the secondaries uniform pale fawn- 
colour: head and thorax greyish-brown ; the abdomen pale brown; the antenne and legs brown. Expanse 
14 inch. 
Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith, April 1888). 
This species is allied to 4. dacia, from which it may be at once distinguished by its 
larger size and entirely different colour. 
DIASTEMA. 
Diastema, Guénée, Sp. gén. des Lép. vi. p. 817 (1852) ; Walker, Cat. xii. p. 879. 
Nipista, Walker, Cat. xii. p. 799 (1857). 
Guénée associated Diastema with Placodes in his family Placodide. The genus is, 
without doubt, very closely allied to Acontia. 
1. Diastema tigris. 
Diastema tigris, Guén. Sp. gén. des Lép. vi. p. 317, Noct. t. 15. f. 2°; Walk. Cat. xii. p. 8797. 
Nipista lineata, Walk. Cat. xii. p. 800°. 
Hab. Mexico, Presidio (Forrer), Tierra Colorada in Guerrero 2000 feet, Teapa in 
Tabasco (H. H. Smith) ; Guaremaua, San Gerdnimo (Champion); Costa Rica (Gabé, 
mus. D.); Panama, Volcan de Chiriqui (Arcé, mus. D.), Panama city (J. J. Walker).— 
CoLoMmBIA ! 2; VENEZUELA °. 
This species varies in colour, some specimens being much darker and more strongly 
marked than others. The Mexican examples are the brightest. 
Mr. Smith met with this insect at Tierra Colorada in the month of October, and at 
Teapa in February and March, 1888. 
DACIRA. 
Dacira, Walker, Cat. xii. p. 801 (1857). 
This genus, which was established by Walker upon a single species, D. combusta, 
from the Amazons, seems to me to be extremely close to Acontia ; one species inhabits 
Central America. D. combusta is now known from as far north as Ecuador.. 
1. Dacira forreri, sp.n. (Tab. XXVIII. fig. 27.) 
Primaries brownish-black, a white spot close to the base, and a broad white band much dentated on the outer 
edge crossing the wing from the costal to the inner margin, the fringe white with a black spot on the 
middle of the outer margin ; secondaries pure white, almost hyaline, but slightly dusky at the apex; the
