268 HETEROCERA. 
This is a common species, and has a very extended range over Tropical America 
and the Antilles. It varies to some extent in colour, some specimens being much 
darker than others; the palest individuals in the large series before me are those from 
San Pedro. 
Xylina inquieta, Walk. (Cat. xi. p. 632), the locality of which is unknown, is possibly 
a synonym of L. orbicularis. 
3. Laphygma eridania.

BRAZIL. 
This species is quite distinct from the one represented by Cramer on his tab. 358. f. E; 
the latter resembles Phalana phytolaccew, Abbot & Smith, but is doubtfully synonymous 
with it. The present insect is labelled Laphygma externa, Walker, in the Oxford 
Museum; this name, however, so far as I am aware, is an unpublished one. 
4, Laphygma triplex. 
Laphygma triplex, Walk. Cat. xi. p. 721°. 
Hab. Mexico, Presidio (Forrer), Tierra Colorada in Guerrero 2000 feet (H. H. Sinith, 
Oct. 1888); Guatemala, Champerico (Champion); Honpuras!; Panama, Volcan de 
Chiriqui (fibbe, in mus. Staudinger). 
This small species is not uncommon in Mexico. It differs from typical Laphygma in 
its smaller size and more slender body, and it may have to be placed eventually in the 
genus Galgula, Guén.; but I have no specimens of the latter before me for com- 
parison. 
PRODENIA. 
Prodenia, Guénée, Sp. gén. des Lép. v. p. 159 (1852) ; Walker, Cat. ix. p. 191. 
The members of this genus are cosmopolitan, and they are found in most parts of 
the globe. Walker in his Catalogues enumerates twenty-five species, and many others 
have since been described. Prodenia is represented in Central America by four species, 
and we have received many examples of three of them. 
1. Prodenia commeline. 
Phalena commeline, Abbot & Smith, Lep. Ins. Georgia, ii. p. 189, t. 95°. 
Trigonophora commeline, Hiibn. Verz. bek. Schmett. p. 217. 
Prodenia commeline, Guén. Sp. gén. des Lép. v. p. 162°; Walk. Cat. ix. p. 192°, and xi. p. 722°; 
Druce, P. Z.S. 1884, p. 322’.
