ZYGMNID^.. 109 



LARViG short, thick, soft and sluggish, usually slightly- 

 hairy ; bearing no resemblance to those of the two preceeding 

 families. 



PuPiG elongated, usually with the leg-cases and wing- 

 sheaths more or less free at the tips ; in a tough silken cocoon 

 on the stems of plants or close to the ground, or even upon 

 rocks or stones. 



Genus 1. PROCRIS. 



Antennae rather short and stout ; in the male with short 

 pectinations, partially so, or slightly toothed, in the female ; 

 wings elongated and rounded, without markings ; thorax and 

 abdomen of moderate thickness, smooth and glossy. 



LARViG short, plump, almost ovate, slightly downy ; mining 

 in the leaves of plants. 



PuPiE in a thin semi-transparent cocoon, concealed close 

 to the ground. 



We have three very similar species, but their distinctions 

 hardly admit of tabulation. 



1. P, globularise. Hub. — Expanse 1| to 1| inch ; fore 

 wings rather broad, bright golden green; antennae somewhat 

 pointed. 



Antennae of the male rather slender, pectinated regularly to 

 the tips, all the pectinations oblique and pointing forward ; 

 of the female much stouter, pectinated equally to, or beyond 

 the middle, then becoming solid, round and thick, with 

 crowded joints ; shaft shining blue-green, pectinations 

 blackish. Head and thorax bronzy green ; abdomen similar, 

 but with a bright golden gloss. Fore wings rather narrow 

 at the base, broader toward the hind margin, with the costal 

 and dorsal margins nearly straight, apex blunt, and hind 

 margin very little rounded ; thinly scaled ; unicolorous, glis- 

 tening bronzy-green or golden-green, with the principal 

 nervures thickened and raised, and longitudinal hollows
