5. Phassus costaricensis, sp.n. (Tab. XXIV. fig. 4.) 
Primaries and secondaries uniform reddish fawn-colour; the primaries thickly marked with darker lines, and 
with a narrow dark reddish-brown line crossing beyond the end of the cell from the costal margin near the 
apex to the inner margin (which it does not quite reach), and an indistinct blackish spot at the end of the 
cell; the underside of both wings reddish fawn-colour: head and the front of the thorax dark reddish 
fawn-colour ; thorax and abdomen black, thickly covered with light brown hairs ; (antenne and legs 
wanting). Expanse 3} inches. 
Hab. Costa Rica (Van Patten). 
The only specimen sent of this species is in very poor condition ; in colour it is very 
distinct from any described species. 
Fam. NOTODONTIDA. 
CECRITA. 
Cecrita, Walker, Cat. v. p. 992. 
Walker founded this genus upon a single species from Nova Scotia. I refer to it 
two species from our country ; both these were placed in other genera by Walker. 
1. Cecrita viridescens. 
Stauropus viridescens, Walk. Cat. xxxii. p. 416}. 
Hab. Mexico, Jalapa (Hége); Guatemata, Volcan de Atitlan 2500 to 3500 feet 
(Champion). 
The two Central-American specimens before me agree well with the type in the 
National collection ; the locality from which the latter was obtained is unknown! I 
do not agree with Messrs. Grote and Robinson in regarding this insect as synonymous 
with C. (Heterocampa) biundata. 
2. Cecrita biundata. 
Heterocampa biundata, Walk. Cat. v. p. 10251. 
Heterocampa obliqua, Packard, Proc. Ent. Soc. Phil. iii. p. 3682; Grote & Robinson, Tr. Am. Ent. 
Soc. 1. p. 178, t. 4. ff. 26 3, 27 23. 
Hab. Norta America, Trenton Falls 1, New York? to Pennsylvania 3.—GUATEMALA, 
San Geronimo (Champion); Panama, Volcan de Chiriqui 2000 to 3000 feet ( Champion). 
The Central-American specimens before me agree well with Walker’s type in the 
National collection. The female example from the State of Panama is more distinctly 
marked with dark brownish spots than any I have seen from North America, but 
specimens from Colombia in my own collection are exactly like those from New York. 
CEDEMASIA. 
Cidemasia, Packard, Proc. Ent. Soc. Phil. iii. p. 359 (1864). 
This genus was founded by Packard upon Phalena concinna, Abbot & Smith, and
