the apical edge is broadly excised ; it seems to bear a considerable resemblance to the 

 so-called mask of the dragon-fly ; the labium and ligula are concealed behind the 

 mentum, and only the points of the labial palpi and ligula are visible. 



The labnim (fig. 5) is very large, rounded, and convex, with a few small teeth 

 on each side, and a row of fine sCtte about half way from the base. 



The insect always carries its formidable mandibles wide open, and is evidently 

 carnivorous.

NOTES ON THE NEUROPTERA OF LANGDALE. 

 BY J. J. KING. 



On August 3r(l, 1881, I left London for a holiday at the English 

 lakes, having selected Skehvith Bridge, which is about three miles 

 from Ambleside, as my head quarters. 



During the month of my sojourn I found the English lake dis- 

 trict to have rather a depressing effect on the spirits of the anxious 

 collector who is eager to be at his work, owing, in a great measure, to 

 the abundant supply of rain, which at times continues without inter- 

 mission for four days (my experience), and causes the river to rise 

 many feet above its usual level, covering up the bushes and herbage 

 along its banks, so that all collecting along the margins of the river 

 has to be suspended for a few days, until the ground gets into a fit 

 state to walk upon. 



In a moderately dry season I should think that the district would 

 turn out well for Neiiroptera, as there is a very great variety of land 

 surface, &c., but my captures were not very extensive, owing to the 

 wet season. 



On the afternoon following my ari'ival, I went down to "Winder- 

 mere lake to search for Setodes argentijnmcieUa, McL., the type 

 specimens of which had been taken by Mr. Hodgkinson, near 

 Windermere lake, but I was unsuccessful in obtaining it near the 

 lake ; Mr. McLachlan having shewn me a number of specimens of 

 this species that he had captured in Belgium, during July, along the 

 banks of a small river, I thought I might obtain it if I made a 

 search along the Brathay river, and towards evening I was rewarded 

 ■with a number of this beautiful little creature, which abounds near 

 Brathay Church. 



I only captured some 84 species, excluding the PerJidas and 

 EphemcridcB (which are not worked up yet), most of them being more 

 or less common ; but among the Triclioptera one novelty fell to my 

 net, namely, a new Hydroptila. 



Below will be found a list of the species taken.
