the British Neuroptera-Planipennia. 217 



Head : vertex castaneous^ blackish in front; back of the 

 head yellow ; front and rostrum reddish, with scarcely 

 darker lines; antennce blackish, the basal joint reddish. 



Prothorax blackish, yellowish at the sides. Meso- and 

 oueta-thorax blackish at the sides, yellow in the middle. 

 Breast grajrish yellow. 



Abdomen blackish, the lateral sutures and the hinder 

 margins of the segments yellow ; in the ? the fifth seg- 

 ment (as well as the three terminal ones) is reddish ; in 

 the $ the second segment is not visibly produced in the 

 middle above ; the fifth a little longer than the fourth, 

 scarcely narrowed posteriorly, the sides of the posterior 

 margins deeply excavated ; the sixth cylindrical, not nar- 

 rowed at the base, above somewhat fuscescent in the 

 middle, and with the upper posterior margin elevated ; the 

 seventh cone-shaped, scarcely shorter than the sixth ; the 

 eighth (terminal) strongly dilated, the branches of the 

 forceps short; appendices long and slender, not dilated, 

 reaching to the base of the forceps, straight, diverging 

 (PL XI. figs. 8, 8a); in the ? , the terminal segments are 

 gradually narrower. 



Legs grayish yellow, or reddish ; tihm with few blackish 

 spines ; spurs testaceous ; tarsi fuscescent ; ungues with 

 few teeth. 



Wings with few grayish or blackish markings, and with 

 the membrane slightly tinted ; the markings are, as a 

 rule, reduced to a broad apical margination and one 

 or two spots beyond the middle, whereof that at the 

 pterostigma is conspicuous ; neuration fuscescent, with a 

 few pale transverse veinlets. 



Size of P. gerrnaniea, and much resembling pale forms 

 of that species. May always be separated by the form of 

 the terminal abdominal segments and appendices of the 

 male. 



Local ; appears to be most frequent in the New Forest. 



Hagen (Ent. Ann. 1858) gives P. apicalis of Stephens 

 as distinct ; the types are not separable from his P. ger- 

 rnaniea. 



It is scarcely probable that we have more species of 

 Panorpa in Britain ; though P. variabilis may occur on 

 some of the higher mountains, and P. meridionalis should 

 be looked for in the south-west of Ireland.
