52 HETEROCERA. 
allied to H. gansonis and H. beatriz, but differs from both, the most marked difference 
being that the extremity of the abdomen is greenish black instead of red, as itis in 
the above-mentioned species. 
4. Homeocera beata. 
Homeocera beata, Butl. Journ. Linn. Soc., Zool. xii. p. 376+. 
Hab. Panama (Ribbe, mus. Staudinger).—Co.omsia (Bouchard 1); Braziu. 
The example in Dr. Staudinger’s collection agrees well in all respects with Mr. Butler’s 
type. 
5. Homeocera salvini. 
Homeocera salvini, Butl. Journ. Linn. Soc., Zool. xii. p. 376; Ill. Lep. Het. pt.i. p. 27, t. 17.8. 4. 
Hab. Panama, Obispo (Salvin). 
The only example of this insect with which I am acquainted was taken by Mr. Salvin 
some years ago near Obispo, and presented by him to the British Museum; it is very 
distinct, and the largest species of this genus found in our country. 
SAROSA. 
Sarosa, Walker, Cat. i. p. 151 (1854). 
Three species only are placed in this genus by Mr. Butler, one of them being found 
in our country. It is allied to Krruca, from which it chiefly differs by its longer and 
narrower primaries and more deeply pectinated antenne. 
1. Sarosa pompilina. (Tab. VI. fig. 24.) 
Sarosa pompilina, Butl. Journ. Linn. Soc., Zool. xii. p. 3777. 
Hab. Panama, Volcan de Chiriqui (Ribbe).—Ecuapor (mus. D.); Brazit, Espiritu 
Santo 1, 
The specimen from Chiriqui agrees well with the type. I have only seen a single 
example from our country. Mr. Champion did not meet with this species. 
ERRUCA. 
Erruca, Walker, Cat. i. p. 165 (1854). 
Walker founded this genus for the reception of a single insect. Mr. Butler, in his 
revision of the Zygeenide in the British Museum, has placed about thirteen species in 
it, mostly from the Neotropical Region. I have lately described three others from 
Ecuador, making about sixteen known species, only one of them having been previously 
recorded from our country. I now add the description of another species.
