4™™. curtantes, 5" 4°. paullo longior ; ungues et pulvilli minuti: 
alz ample; nervus ulnaris humerali multo brevior, radialis sat

Sp. 1. Euch. Volusus. Mas. Cuprea viridi varia, abdo- 
men viridi-eneum, antenne nigre, pedes ferruginei, femora 
viridia, ale limpide. 
Mas.—Cuprea: capitis vertex viridis: oculi et ocelli obscure rufi : 
antenne nigra; articuli 1". et 2", nigro-cuprei: thorax utrinque 
et subtus viridi-varius: abdomen viridi-aneum: pedes ferru- 
ginei; coxee virides; femora viridia, apice ferruginea; protarsi 
obscuriores; ungues et pulvilli fusci: ale limpide; squamule 
ferruginex ; nervi fulvi; stigma fuscum. (Corp. long. lin. 23; 
alar. lin. 3}.) 
Antenne 13-jointed, 1". joint linear; 2%. very short, cup-shaped, 
3". obconic, longer than the 1*., 4". very short, producing above 
towards the outside a long arched subclavate pilose branch, the 
following joints to the 12". inclusive becoming gradually longer 
and producing a similar branch from the apex, and the exterior 
ones also a shorter branch towards the inner side; the last five 
branches of this series are sufficiently distinct, but that of the 8. 
joint is reduced to a short tooth. The 18", joint is as long as the 
longer branch of the preceding, and like it, subclavate and pilose.”
