208 Mr. R. MacLachlan's Monograph 0/ 



Appears in summer ; scarce, but more frequently met 

 with than the preceding" species. 



According to Schneider, both species are of rare oc- 

 curence on the continent, though widely distributed. I 

 have never seen either of them alive. In fulviceps the 

 lower half of the third cubital cellule is frequently divided 

 by a transverse veinlet. 



The following South-European and exotic species, 

 should be placed in Nothochrysa. — Chrysopa italica, Rossi 

 (S.Europe); C. sfo'(/mai'ica, Rambur (S. Europe); C. Cor- 

 sica, Hagen (Corsica); G. cequalis, Walker (uncertain 

 locality); C variegata, Burmeister (Comoro Islands); C. 

 rufostigma, M'Lachlan (S. Africa) ; G. gigantea, M^Lach- 

 lan (S. Africa) ; G. neurocles, Rambur (S. Africa ; the 

 third cubital cellule is not correctly delineated by 

 Schneider); G. tripunctata,* M^Lachlan (Australia); G. 

 insignis, Walker (Australia); G. infecta, Newman (Mala- 

 bar); and perhaps others with which I am unacquainted. 



A group of species, chiefly from tropical America, of 

 which G. varia of Schneider may be taken as the type, 

 distinguished by an excised labrum, very long antennae, 

 broad wdngs, graceful form, and generally pale colour, 

 (often with rich markings) , will form another genus, to 

 which the name Leucochrysa may be applied. 



Division III. PANORPINA. 



Aoitennce sub-setiform or filiform. Head small ; front 

 produced into a rostrum, which is deflexed vertically ; 

 ocelli present (Panorpa) or absent (Boreus) ; mandibles 

 usually toothed internally. Prothorax narrow and trans- 

 verse. Meso- and ineta-thorax large. Ahdomen sub- 

 cylindrical, the male with the three terminal segments 

 usually modified. 



Legs long and slender ; tihioe cylindrical ; tarsi with the 

 first joint very long ; ungues usually serrated internally f 



* In describing C. tripunctata (Journ. Linn. Soc. ix. 250), I placed it 

 in the section " labrum antice rotimdatum." The true detiuition of this 

 part in the type was difficult, o^ving to the position the palpi had assu- 

 med. Further examination induces me to believe that the labrum is in 

 reaUty slightly emarginate, as from analogy it should be. 



f The genus Bittacus (which does not occur in the British Isles) has 

 only one claw.
