Black, except the head, which is bright red, the prelabrum, however, shining black ; legs, including the tarsi, 
black ; wings intensely blackish, especially along the costa; auxiliary cell very elongate, the end of the 
first vein being much beyond the small cross-vein ; second vein reaching to near the end of the costa ; 
third basal cell triangular and pointed, but not elongate. .

A single female specimen of this species has been received from Chontales.

Calobata calocephala, Bigot, Ann. Soc. Ent. Fr. 1886, p. 375. 4°. 
Hab. Mexico?*, Omealca, Orizaba (JZ. Trujillo), Atoyac in Vera Cruz (Schumann 
& H. H. Smith); Guatemata, Zapote and Capetillo (Champion); Costa Rica, Caché 
(Rogers). 
Several specimens of both sexes. In its general facies and coloration, and in the 
venation of the wings, this species agrees with C. erythrocephala, but differs from it in 
having the first joint of the fore and hind tarsi white. The hypopygium of the male 
is broad, turned downwards and truncated at the apex; inwards, there are two long 
and two short filiform appendages, which are hairy at the tip. 
Wiedemann (Aussereur. zweifl. Ins. ii, p. 533) mentions a variety of C. erythrocephala, 
F., with white tarsi, this being probably the C. diversa of Schiner. Dr. Giglio-Tos 
(Mem. R. Accad. Scienze di Torino, ser. 2, xlv. (sep.) p. 62) also regards this latter as 
a variety only ; but, as intermediate specimens have not been found, I believe that it 
is a good species.
