50 HETEROCERA. 
This fine species is most nearly allied to M. calvipes, but it is a very much larger 
insect. In Guatemala it appears to be rare, where Mr. Champion only obtained two 
examples. The type of this insect was kindly sent to me by Mons. C. Oberthiir for 
examination; it only consists of the wings and hind legs gummed on to a card, but 
still quite sufficient to identify the species with certainty. 
ISANTHRENE. 
Isanthrene, Hiibn. Verz. bek. Schmett. p. 125; Walker, Cat. i. p. 154 (1854). 
This genus has had about eleven species placed init. All these insects are of a very 
hornet-like appearance. Five species are found in our country. 
1. Isanthrene pompiloides. | 
Glaucopis (Isanthrene) pompiloides, Walk. Cat. i. p. 1567. 
Isanthrene pompiloides, Butl. Journ. Linn. Soc., Zool. xii. p. 874; Tll. Lep. Het. pt. i. p. 26, t. 12. 
f. 10. 
Hab. Mexico, Valladolid in Yucatan (Gaumer); GuateMaLa (mus. Brit.1). 
This species seems to be a Mexican insect, the only authority for its occurrence in 
Guatemala being the specimen in the British Museum. Mr. Champion did not meet 
with it. 
2. Isanthrene echemon, sp. n. (Tab. VI. fig. 22.) 
Primaries yellowish hyaline, darker along the costal margin, the inner and outer margins narrowly banded 
with black, rather wider at the apex; secondaries yellowish hyaline, the inner and outer margins bordered 
with black: the palpi, head, thorax, and abdomen deep black; antenne deep orange-yellow, almost scarlet 
at the base; the legs brownish black. Expanse 2 inches. 
Hab. Guatemaua, San Juan in Vera Paz (Champion). 
Mr. Champion only obtained a single specimen of this fine species; it is quite unlike 
any other described Jsanthrene with which I am acquainted, its nearest ally being the 
Mexican I. pompiloides, Walker, a species that is perhaps peculiar to that country. | 
3. Isanthrene championi, sp.n. (Tab. VIII. fig. 6.) 
Primaries and secondaries reddish-brown hyaline, the outer and inner margins of both the primaries and 
secondaries narrowly bordered with black: the head, thorax, and abdomen black, with two minute yellow 
spots at the base; antenne pale yellow at the tips, almost red at the base; legs black, the veins on the 
upperside are black, on the underside they are bright scarlet. Expanse 23 inches. 
Hab. Panama, Bugaba 800 to 1500 feet (Champion). 
I have named this very fine insect after Mr. Champion, who obtained a single | 
example of it in the neighbourhood of Bugaba. It is a very distinct species, its nearest 
ally being L. echemon from Guatemala. 
4, Isanthrene incendiaria. 
Glaucopis incendiaria, Hiibn. Samml. exot. Schmett. t. 165.
