INSECTS 



McLach., are recorded from Addington and Leith Hill, but these species 

 are always confused and their distinction is doubtful. H. subnebulosus, 

 Steph., so frequently found amongst fruit trees, is distributed over the 

 county, and H. nervosus, Fabr., appears chiefly to frequent birch ; it 

 occurs on Esher Common (Lucas). H. concinnus, Steph., the largest of 

 the group, is recorded from Addington (Wormald), and is common at 

 Oxshott Common and Ockham Common. The three species of Conio- 

 pteryx C. aleyrodiformis, Steph., C. psociformis, Curt., and C. tineiformis, 

 Curt. occur freely, but are much overlooked. Cbrysopa Jlava, Scop., 

 has occurred at Leatherhead, and probably throughout the county, but is 

 always with the abundant C. vittata, Wesm. C. alba, Linn., occurs in 

 the Esher Woods ; C. Jtavifrons, Brau., at Box Hill, Weybridge and 

 Merrow Downs ; C. tenella, Schr., at Leatherhead, Ockham, Weybridge 

 and Esher. C. vu/garis, Schr., and its winter condition, carnea, Steph., 

 are commonly distributed. C. septempunctata, Wesm., the ill-savoured 

 stink-fly, is also generally distributed. C. aspersa, Wesm., is in profusion 

 on Ockham Common and generally common in the county. C. ventra/is, 

 Curt., occurs sparingly at Weybridge and Ockham Common, but is 

 frequent on Bookham Common. C. pbyllocbroma, Wesm., is not rare in 

 the neighbourhood of Newark Abbey and has been taken near Byfleet. 

 C. perla, Linn., generally common, is particularly so at Byfleet. C. dor- 

 sa/is, Burm., was recognized in 1900 for the first time as British, being 

 taken by Mr. Beaumont at Oxshott. Nothochrysa capitata, Fabr., is found 

 singly at Leith Hill, Esher, Ockham Common and other fir districts. 

 Of the third division or Panorpina Panorpa communis, Linn., and P. 

 germanica, Linn., are common throughout the county ; but P. cognata, 

 Ramb., common on the downs at Folkestone, has not yet been recorded 

 from Surrey. Boreus hyemalis, Linn., occurred in 1867 at Shirley near 

 Croydon (Douglas and Scott). 



The Trichoptera, the fifth and last of the somewhat ill-assorted 

 groups at present included in our list under the general name Neuroptera, 

 are well represented in Surrey. Few counties indeed are better adapted 

 to this water-loving group. Strong running streams and sluggish brooks, 

 canals and large ponds, woodlands and moor, marsh and bog all con- 

 tribute their quota of species peculiar to the varying nature of the 

 localities. 



The Phryganeidce and many of the Limnophilidfe frequent the more 

 sluggish and even stagnant waters, and may be beaten from bushes about 

 the edge of a pond, or swept from reeds or coarse herbage round its 

 margin, or disturbed from the overhanging banks of a moorland drain. 

 Some wander far from the place of their birth, and may be beaten out 

 in woods, especially fir woods, or even taken at ' light ' in towns or at 

 the lepidopterist's ' sugar.' 



Most of the long-horned Leptoceridce love moving rather than 



stagnant waters, and may be disturbed from the overhanging trees and 



bushes or from reeds, or frequently may be seen in the daytime in 



countless myriads performing their mazy dances over the water, their
