54 HETEROCERA. 
3. Myrmecopsis crabronis, sp.n. (Tab. VIII. fig. 9.) 
Primaries and secondaries brownish hyaline, darkest along the costal margin: head, thorax, abdomen, and 
legs greasy black ; antenne reddish brown. Expanse 13 inch. 
Hab. Guatemata (mus. Staudinger); Panama, Volcan de Chiriqui (Champion). 
This species is allied to MW. polistes, Hiibner, but differs from it by being considerably 
larger, and by having a black head, thorax, and abdomen, instead of yellowish brown, 
as in that species. 
SPHECOSOMA. 
Sphecosoma, Butler, Journ. Linn. Soc., Zool. xii. p. 381 (1876). 
This genus has three species placed in it by Mr. Butler, two of which occur pretty 
commonly in our country. 
1. Sphecosoma fasciolatum. (Tab. VI. fig. 26.) 
Sphecosoma fasciolatum, Butl. Journ. Linn. Soc., Zool. xii. p. 881°. 
Hab. Guatema.a, Panzos, Teleman; Panama, Bugaba (Champion).—Co.omBiA, Santa 
Marta!; Braziu. 
This wasp-like insect was pretty common at Teleman, but I have only received a 
single example from Bugaba. 
2. Sphecosoma testaceum. (Tab. VI. fig. 27.) 
Glaucopis (Pseudosphex) testacea, Walk. Cat. i. p. 1967. 
Sphecosoma testaceum, Butl. Journ. Linn. Soc., Zool. xii. p. 381. 
Hab. GuateMaa, Panzos, Teleman (Champion).—Brazit 1. 
This species closely resembles Myrmecopsis polistes, Hiibn. 
GYMNELIA. 
Gymnelia, Walker, Cat. i. p. 152 (1854). 
The genus Gymnelia, as now restricted, forms a very natural little group of species, 
in form resembling Homeocera, two species as yet only occurring in our country. 
1. Gymnelia gigantea, sp.n. (Tab. VIII. fig. 5.) 
Primaries hyaline, the base, costal, outer and inner margins, and a band at the end of the cell black; secon- 
daries, the base and inner margin broadly black, the outer slightly bordered with black: the head, thorax, 
and abdomen black ; the collar dark blue and the abdomen banded with the same colour; antenne black ; 
legs bright scarlet. Expanse 2} inches, 
Hab. Costa Rica (Van Patten). 
This very fine species is closely allied to G. torguata, from which it differs in having 
the abdomen all black banded with blue, instead of half red, as in that species, also in 
the legs being scarlet instead of black. It is the largest species known to me.
