144 MANDIBULATA. — NEUROPTERA. 



Very glossy, deep black : collar slightly wrinkled ; abdomen pitchy-red ; 



femora pitchy-black ; tibiae pitchy-red; tarsi black; wings brownish, with 



darker nervures, the transverse ones towards the apex bordered with 



dusky. 

 Antennae sometimes pitchy at the base. 



Common at Ripley, in June and July ; also found in Scotland. 



B. Anterior wings destitute of a x-like plexus of nervures ; hinder margin 

 with nine longitudinal nervures. 



Sp. 15. variegata. Plate xxxi. f. 2 — Fusco-nigra, collare pedibusque rufis 

 nigra variis, alis pallide cinereis fasciis 2-bus fuscescentibus. (Long. corp. 

 4lin. ; Exp. Alar. 11 lin.) 



Ne. variegata. Steph. Catal. 316. No. 3558. 



Head and antennae deep black, the former rather small; collar pale red, 

 slightly clouded on the disc with blackish ; meso- and meta- thorax black ; 

 abdomen pitchy above, dusky beneath ; legs pale red; coxae ochreous, tip 

 of the femora black ; apex and tip of the tibiae, and a line on their inner 

 edge, as well as the tarsi, black ; wings long and narrow, with numerous 

 nervures, pale ashy, with two or three transverse fuscous streaks ; nervures 

 also fuscous ; posterior wings fuscescent, especially at the apex. 



I suspect this insect is the true Phryganea nebulosa of Linnaeus. 



Apparently rare : my specimen occurred near Hertford in June. 



Genus XXX.— LEUCTRA, Stephens. 



Antennw placed somewhat remotely in front beneath the eyes, somewhat 



moniliform and pilose, or setaceous and simple, with distinct joints ; in all 



the basal joint robust, the 2nd slightly smaller : labrum transverse, rounded 



in front : palpi with the terminal joint a little acute : htad large and 



depressed, or small and inflexed : eyes moderate, prominent : ocelli 3 : collar 



more or less quadrate, longitudinally sulcate and rugose : wings incumbent 



during repose; anterior elongate, somewhat acuminate, the transverse 



nervures placed rectangularly about the middle of the costa, and not forming 



a x-like mark by the union with the longitudinal ones; posterior pair 



shorter, narrower, acuminated, and incised on the outer margin : abdomen 



somewhat linear-elongate, the apex not furnished with jointed setae: legs 



rather slender, simple : feviora and tibiae slightly compressed and striated : 



tarsi with the intermediate joint slightly produced beneath. 



The great dissimilarity of the neuration of the wings of the insects 



included in this genus from those of the foregoing— as exhibited in 



Plate xxxi. figs. 2 and 3 — sufficiently indicate their distinction; 



these organs are also more elongate and acuminated at the apex, 



the anterior pair are narrower ; the head smaller, the antennae more 



distinctly articulated, &c.
