MAMESTRA.—APAMEA. 273 
3. Mamestra dotata, sp. n. (Tab. XXVI. fig. 21.) 
Primaries reddish-fawn-colour, crossed from the costal margin to the inner margin by three very indistinct dark 
brown lines (the second the widest and placed about the middle), with a whitish spot at the end of the 
cell and a submarginal row of very minute white dots extending from the apex to the anal angle, the dot 
close to the anal angle the largest and very distinct ; secondaries of the male semihyaline, whitish, shaded 
with brown on the costal margin and at the apex, those of the female very much darker in colour; the 
underside of both wings very pale in colour and without markings: head, thorax, and abdomen reddish- 
fawn-colour, the latter becoming paler near the anus, the legs and antenne pale brown. Expanse 13 inch. 
Hab. Mexico, Jalapa (Schaus); Guatemata, Las Mercedes 3000 feet, Volcan de 
Atitlan 2500 to 3500 feet (Champion); Panama, Volcan de Chiriqui (Champion, Ribbe). 
This species varies slightly, some specimens being more strongly-marked than others. 
M. dotata may be very readily distinguished from any other species of the genus by 
the white dot at the anal angle of the primaries. 
4. Mamestra hipparion, sp.n. (Tab. XXVI. fig. 24.) 
Primaries pale glossy-brown with a reddish tinge in certain lights, a dark central streak extending from the 
base almost to the outer margin (which it does not quite reach), a pale brown spot at the end of the cell, 
several minute dark markings along the costal margin, and a series of very minute indistinct dots along 
the outer margin; secondaries pale glossy greyish-brown, more obscure in the female, darkest on the 
outer margin from the apex to the anal angle; the underside of both wings considerably paler than the 
upperside: head, thorax, and abdomen of a darker brown than the primaries, the anus pale brown ; 
antennee and legs brown. Expanse 13 inch. 
Hab. Costa Rica, Volcan de Irazu 6000 to 7000 feet, Rio Sucio (Rogers). 
This is a very dull-coloured insect, and it somewhat resembles Perinenia lignosa, 
Butler, from Japan. 
APAMEA. 
Apamea, Ochsenheimer, Schmett. Europ. iv. p. 75 (1816) ; Walker, Cat. ix. p. 248. 
Two species only of this genus are known to us from Central America. 
1. Apamea iaspis. 
Apamea iaspis, Guén. Sp. gén. des Lép. v. p. 209°; Walk. Cat. ix. p. 250°. 
Hab. Norta America, New York!?.—Mexico, Jalapa (Schaus); GuaTemaLa, San 
Gerénimo (Champion); Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 
We have received five specimens only of this species. 
2. Apamea intermittens. 
Apamea intermittens, Walk. Cat. xv. p. 1686°. 
Hab. Mexico, Las Vigas (Schaus); GuatemMata, Senahu (Champion).— ANTILLES, San 
Domingo 1. 
Our Guatemalan specimen agrees well with Walker’s type in the National Collection.
