HEMEROBID.E.— CHRYSOPA. 101 



a fuscous dot towards the base, and two oblique somewhat repanded 

 streaks towards the apex, the first terminating on the inner edge with a 

 small triangular white spot; the inner and hinder margins are umbre- 

 coloured, on the latter interrupted with whitish ; posterior wings rather 

 pale, especially towards the base. 



Also a local insect : I am indebted to Mr. Little for the first 

 communication thereof; he found it at Raehills in Scotland, and 

 Mr. AValker has taken it near New Lanark. 



GexXus XIX.— CHRYSOPA, Leach. 



Antennm as long as, or longer than, the body, filiform, the articulations oblong 

 and cylindric, the basal one very large : labium very large, orbicular, entire : 

 labrum transverse, with a central marginal notch: head short: eyes very 

 globose, prominent (brilliant during life) : ocelli wanting : collar somewhat 

 quadrate, nearly as wide as the head : thorax broad, rounded in front : wings 

 deflexed during repose, iridescent, glabrous, long and narrowish, somewhat 

 elliptical: costa with transverse simple nervures only; inner portion with 

 numerous reticulations, forming three rows of areolets on the disc, and the 

 transverse nervures mostly bifid on the margins : legs short, slender, and 

 simple. 



The insects of this genus may be known by the extreme brilhancy 

 of their beautiful globose eyes, which are of rich golden tints during 

 life, thence called golden-eyes, but which fade after death to a 

 greenish- or purplish brown ; but, exclusively of this distinction, the 

 very different neuration of the wings, the structure of the antennse 

 and trophi, well distinguish them : they have very delicate wings, 

 upon the surface of which the most brilliant iridescent tints are pro- 

 duced by varying the direction of the light ; though these fine out- 

 ward blandishments are sadly contrasted with the fetid odour that is 

 evolved from the insects when handled.

Ch. fulviceps. Steph. Catal. 310. No. 3449. 



Head bright fulvous ; eyes black ; collar ochreous, with a faint black spot on 

 each side ; thorax also ochreous, irregularly spotted, or varied with black 

 on the sides ; abdomen fuscous, with a lateral line, and the apex beneath 

 ochreous ; legs pale ; wings with pale fuscescent nervures, and a very faint, 

 fuscescent, and elongated stigma towards the apex of the costa. 



The outer longitudinal nervure is sometimes pale yellowish-green.
