OF WASHINGTON. 83 
FEBRUARY 2, 1905. 
The 1 93d regular meeting was held at the residence of Dr. 
L- O. Howard, 2026 Hillyer Place, N.W., Vice- President 
Hopkins in the chair and Messrs. Alwood, Ashmead, Barber, 
Benton, Burke, Cook, Currie, Doolittle, Dyar, Fairchild, 
Fiske, Girault, Hinds, Howard, Hunter, Marlatt, Morrill, 
Morris, Pierce, Quaintance, Schwarz, Scott, Titus, and Webb, 
members, and Messrs. Beattie, Crawford, Hooker, Norton, 
Rankin, Sanders, and Sasscer, visitors, present. 
Dr. Dyar showed a specimen of the larva of Castnia licus 
Drury which has been received at the Bureau of Entomology 
as injurious to sugar cane in British Guiana, by boring in 
the stems. Very little is known about the larvae of the Cast- 
nidge except that they are borers. This has led some to 
infer that there is a relationship between them and the boring 
Hesperiidae such as Megatkymus yuccas, but such should not 
be the case, as the venation is entirely different in these groups. 
The larva before us bears out this conclusion, as it is a true 
Tineoid form, not related to the Butterflies, but to the Cossidae 
and Sesiidae. 
LARVA OF CASTNIA LICUS Drury. 
BY HARRISON G. DYAR. 
Larva. Head large, rounded, full, somewhat flattened, apex retracted 
in joint 2; clypeus small, shield-shaped, but with large paraclypeal pieces 
which touch the vertical membrane; antennae very small, rudimentary, 
shorter than the palpi; ocelli, nearly obsolete, two small ones seen near 
the antennae; brownish luteous, darker around the mouth, the mandibles 
and articulations black. Body robust, cylindrical; thorax enlarged, 
especially the dorsal parts of joints 3 and 4; joint 5 small, both dorsally 
and laterally; joints 6 to 10 about equal, 1 1 and 12 a little smaller. Spira- 
cles large, narrowly elliptical, the one on joint 12 largest and directed 
obliquely backward. Thoracic feet very short, almost rudimentary, 
projecting laterally. Abdominal feet on joints 7 to 10 distinctly elevated 
but without the ordinary hooks. They are covered .with numerous 
minute spicules, not in rows but in a large patch which narrowly runs 
across between the feet. These spicules are present also on the ventral 
side of joints 3 and 4 and dorsally on joints 3 to 11. On joints 7 to
