FAMILY COSSIDAE 
** Bright insect, ere thy filmy wing, 
Expanding on the breath of spring, 
Quivered with brief enjoyment, 
’T was thine for years immured to dwell 
Within a lone and gloomy cell, 
To eat,—thy sole employment .”—Acheta Domestica. 
The Cossidce, “ Goat-moths,” or “Carpenter-worms,” as they 
are familiarly called, have sorely puzzled systematists. Some 
writers have been inclined to regard them as allied to the Tortri- 
cidce. We assign them the position in the linear series which is 
accorded them by Hampson and also by Dyar. They form a very 
distinctly defined group, whatever their relationships may be. 
They are succinctly described by Hampson in “The Moths of 
India,” Vol. I, p. 304, as follows: “Proboscis absent; palpi usu¬ 
ally minute or absent; antennae bipectinated to tip or with distal 
half simple in both sexes, or wholly simple in female. Tibiae with 
spurs absent or minute. Fore wing with vein 1 b forked at base; 
1 c present; an areole formed by veins 7 and 10; veins 7 and 8 
forking after the areole; the inner margins usually more or less 
lobed. Hind wing with three internal veins; vein 8 free from 
the base or connected with 7 by an erect bar at end of cell. Both 
wings with forked veinlets in cell. The female may have as 
many as nine bristles to the frenulum.
