236 HETEROCERA. 
This species appears to come nearest to E. packardi, Morrison, a bad specimen of which 
is contained in the Grote collection now in the National Museum. 
LEPTOSPHETTA. 
Leptosphetta, Butler, Trans. Ent. Soc. Lond. 1878, p. 67. 
Leptosphetta is stated by its author to be allied to the eastern genus Sphetta and to 
have the antenne minutely pectinated as in Calledema. A single species only, L. rab- 
dina, from the Amazons, was included in the genus by its describer; this insect appears 
to be widely distributed and to extend northwards to Costa Rica. 
1. Leptosphetta rabdina, 
Leptosphetia rabdina, Butl. Trans. Ent. Soc. Lond. 1878, p. 67 '. 
Hab. Costa Rica, Irazu 6000 to 7000 feet (Rogers)—Cotomsia, Bogota; Ecuapor ; 
Amazons, Rio Jutahi (Trail 1). 
A single example of this insect was captured in Costa Rica by Mr. Rogers. I have 
a good series of specimens of both sexes obtained by the late Mr. Buckley in Ecuador ; 
these are considerably brighter in colour than the individual from Costa Rica.
