132 LEPIDOPTERA OF NORTH AMERICA.

 and unsatisfactory diagnoses of the imago an almost futile task. 



CLEMENS. 



FAM. IY. ZYGAENIDAE. 



Front squamose. Palpi cylindrical, barbate, or hirsute ; 

 third article very distinct, sometimes naked. Antennas fusi-

 Tongue long, convolute. Tibias armed at the apex with four 

 more or less distinct spurs. Wings deflected, longer than 

 the body; primaries more narrow; secondaries rounded, very 

 rarely angular. Flight diurnal. Larva rather contracted, 

 sluggish; head small, pubescent or pilose. Pupa folliculate. 



ALYPIA KIRBY. 



Body short, rather robust. Head small ; eyes moderate. Pro-

 antennae thicker in the middle than at the apex, nearly as long as 

 the body; thorax thick; abdomen more slender. Wings rather 

 wide, not elongate, rounded on the margins. Feet robust, rather

 Larva cylindrical, elongated, yellow, with transverse rows of black 

 points, slightly hairy, without a caudal horn. Lives on the grape-
