182 A. R. Grote's Notes on the Zygsenidse of Cuba. 



CALLICARTJS, n. g. 



The antennae are sub-serrate, gradually swelled towards their tips, 

 which are slenderer and flexuous. The labial palpi are held freer and 

 more greatly exceed the "front" than in Horama. The head is small- 

 er and the prothoracic pieces are narrower than in Horama. Wings, 

 narrow, proportionally shorter than in its ally ; primaries widening rather 

 suddenly towards their external margin, which latter is rounded and 

 less oblique than usual. Nervules short; 3rd and 4th median nervules 

 more widely separated at base than in Horama. Legs, long and finely 

 scaled; middle tibiae with minute apical spurs; posterior pair largely 

 developed, with a thick brush of long hair fringing either side of the 

 lower half of the tibiae and upper part of the tarsi. 



C. plumipes {Sphinx plumipes, Drury, Exot. Vol. IT, Plate 27, fig. 

 3,) belongs to this genus, which may be distinguished from Horama 

 by the differing antennae, reduced prothoracic pieces and the differently 

 shaped primaries. The neuration seems to me to be quite distinct, 

 but I have only a single individual before me, and cannot fully enter 

 into the comparative details, owing to my desire to keep the specimen 

 intact. 



The beautiful species of this genus are black or blackish, with ex- 

 aggeratedly tufted posterior legs, reminding us of the antennal orna- 

 mentations of certain Coleopterous insects belonging to the Family 

 Cerambycidae. 



Callicarus pennipes, n. s. 



Black. Wings, obscure blackish, immaculate. Primaries with a 

 few basal whitish scales; longitudinally, along the centre of the wing 

 from the base to the fourth median nervule, the wings are narrowly 

 sub-diaphanous ; beyond, above the median nervure, the tegument is 

 for a narrow space entirely deprived of scales, and similarly and 

 more prominently so at the base of the interspaces between the second 

 and fourth m. nervules; the veins being covered with blackish scales. 

 Secondaries, obscure black, with a central, longitudinal, sub-diaphanous 

 streak. Under surface, resembling upper; the primaries show a nar- 

 row sub-costal whitish line, extending from the base of the wing for 

 about half of its length, and becoming gradually obsolete. Secondaries 

 with two or three faint, parallel, sub-costal, whitish lines ; the very nar- 

 row fringes are whitish. 



Head, blackish. The eyes are narrowly bordered on the front with 

 white scales, which expand before the antennal insertion into lateral 

 white dots, and there is a third, centrally covering the space between
