the British Neuroptera-Planipennia, 153 



The transverse nervule in the sub-costal area of the 

 anterior wings placed in the middle of the first cellule 

 between the radius and sector, or more towards the 

 broad apical end of that cellule (PL VIII. fig. 2, indi- 

 cated at a) . 



Apex of the abdomen of the $ above with a smaller 

 fleshy lobe, with an oval concave space in the centre ; 

 the appendices proceeding from this lobe thicker at the 

 apex ; ventral valve very much smaller, triangular, the 

 apex somewhat acute (PI. YIII. fig. 2 c) . A reference 

 to the figures will render these difi'erences in the apex 

 of the c? abdomen more intelligible. 



The slight difi'erences in the neuration, above noted, 

 appear to be constant ; but I can see no other certain 

 neural characters ; indeed, the arrangement of the veins 

 differs greatly in individuals, and in the opposite wings 

 of the same specimen; hence the figures on Plate VIII. 

 must only be regarded as representing the one character 

 of the nervule in the sub-costal area. 



This species is overlooked ; it probably appears when 

 8. lutaria is nearly over. I have taken it at Eannoch 

 (Perthshire) ; on the banks of the Mole, near Box Hill ; 

 and in the neighbourhood of Haslemere. Mr. Dale has 

 found it in Dorsetshire. 



Family II. RAPHIDIID^. 



The characters of the family are those of the genus as 

 given below. 



Genus I. Raphidia, Linne. 



Head elongate, contracted behind ; vertex nearly plane ; 

 ocelli present ; * antennm slender, short ; clypeus very 

 narrowly transverse ; labrimt small, nearly quadrate ; 

 maxillce with two short and thick end-lobes (PL VIII. 

 fig. 3e) ; maxillary palpi with the joints short, the ter- 

 minal one obtuse ; mandibles strongly toothed within ; 

 labium longer than broad ; labial palpi with three short 

 joints, the terminal one the smallest. 



Prothorax long and slender, sub-cylindrical, dilated 

 posteriorly ; the sides closing over the prosternum, and 

 leaving the latter free in a limited space at the posterior 

 end, where are attached the anterior legs. Meso- and 

 tneta-thorax nearly equal, transverse, much broader than 

 the prothorax. 



* In Inocellia, a very closely allied genus, the ocelli are absent.
