CALLICARUS.—MASTIGOCERA. 49 
1. Callicarus plumipes. 
Sphinx plumipes, Drury, Ill. Exot. Ins. ii. t. 27. f. 3. 
Euchromia (Horamia) plumipes, Walk. Cat. i. p. 252. 
Callicarus plumipes, Butl. Journ. Linn. Soc., Zool. xii. p. 372; Ill. Lep. Het. i. p. 25, t. 8. f. 2. 
Hab. Mexico, Valladolid in Yucatan (Gaumer); GuatumaLa, San Gerdénimo (Cham- 
pion); Nicaracua, Chontales (Belt). 
2. Callicarus laconia, sp. n. (Tab. VI. fig. 18.) 
Primaries and secondaries uniform brownish black, much the same colour as C. plumipes, several very minute 
blue dots at the base of the primaries: head black, with the front blue; thorax black, with three bluish- 
white spots on each side; abdomen black, with two blue spots close to the base, and a row of bluish-white 
dots on either side; antenne and palpi black, not tipped with white as they are in C. plumipes; legs all 
black, the hind legs thickly covered with long hairs. Expanse 1 inch. 
Hab. Mexico, Valladolid in Yucatan (Gawmer). 
Of this pretty little species I have only received a single example in poor condition ; 
it is easily distinguished from C. plumipes by its smaller size, black abdomen spotted 
with blue, shorter and black hind legs. 
3. Callicarus texanus. 
Callicarus texanus, Grote, Proc. Ent. Soc. Phil. vi. p. 1847. 
Hab. Norta America, Texas! —Mexico, Milpas (Forrer), Jalapa (Hoge). 
This species closely resembles Mastigocera edipus. It isa smaller and much slighter- 
looking insect. 
MASTIGOCERA. | 
Mastigocera, Boisduval, Lép. Guatemala, p. 81 (1870). 
This genus is very closely allied to Callicarus, from which it differs as follows :—the 
antenne are longer, the palpi more erect, and the second joint much longer than in 
Callicarus ; the neuration is very much the same, but the tuft of hair on the hind legs 
is much larger, and more in the shape of a ball. Mr. Champion tells me that he 
always found these insects beneath the leaves of certain trees when in flower. 
1. Mastigocera calvipes. (Tab. VI. fig. 20.) 
Mastigocera calvipes, Boisd. Lép. Guat. p. 81*; Butl. Journ. Linn. Soc., Zool. xii. p. 373 *, 
Hab. Mexico!; Costa Rica, Irazu (Rogers).— VENEZUELA?. 
I have examined the type of this species; the specimen before me agrees with it in 
all respects. The figure is taken from the Costa-Rican example. 
2, Mastigocera cedipus. (Tab. VI. fig. 19.) 
Mastigocera edipus, Boisd. Lép. Guat. p. 81; Butl. Journ. Linn. Soc., Zool. xii. p. 373. 
Hab. Mexico, Valladolid in Yucatan (Gawmer); GuatEMALA, San Gerdnimo (Cham- 
pion).
