mental, with fringed tarsus ; palp large ; both wings broad. 

 7. Morphince fore-leg small, not fringed ; palp small ; wings 

 broad. 8. Satyrincu fore-leg small; antenna? delicate; 

 palps closely approximated ; wings ocellated. 9. Liby- 

 theino? palp as long as, or longer than thorax, thick, 

 straight ; fore-limb small in male, perfect in female. 10. Ery- 

 cininae palp small, with naked end-joint; fore-leg pefect. 

 ii. Lycaenince fore-leg small ; palps long; caterpillars 

 flat, short and broad ; eyes of imago, hairy (Thecla), or 

 naked. 



Order 13. Coleoptera : Metabolous four-winged, with a 

 free large prothorax ; and the anterior pair of wings (elytrnc) 

 hard, fully chitinizcd, and covering the succeeding pair; 

 head mostly recept, with two compound, and rarely any sim- 

 ple, eyes ; antennae, variable, 6-30 jointed ; mandibles chiti- 

 nous ; maxillae often leathery, with an aborted inner lamella; 

 maxillary palp four-jointed ; labial three-jointed ; ligula un- 

 divided ; mentum overlaps the labrum proper; mesothorax 

 weak, with a scutellum, and bearing the elytra? ; metathorax 

 strong, bearing the functional wings. The elytra? have three 

 margins ; the inner is usually straight (except in Meloe, &c.) 

 Where they touch medio-dorsally they form a suture, along 

 which they may be adherent, when the hind pair of wings 

 are functionless (cfy/t\r conna/a}. The hinder edge may 

 form an apex, or may be shortened (e. breviatd], so as 

 not to cover the posterior abdominal rings, when they are 

 called c. truncata; when their inner edges do not touch they 

 are e. dehisccntia, or, if they overlap, e. complicantia. The 

 hind-wing has its costa? mostly longitudinal, and it is folded 

 longitudinally, and once or twice transversely, so as to lie 

 at n-st completely under the elytron. The cOStX
