Psocidx at Wolclng. — In September, 1903, tlie late Mr. McLachlan asked me 

 to collect Psocids for hiin when I was at Margate, and gave a list of the few species 

 I captured in the October number of this Magazine for that year. This gave me 

 an interest in these minute creatures, and I have continued to collect them since. 

 In the neighbourhood of Woking I have found several interesting species, so I give 

 below a list of those that have occurred so far: — 



Psoctis morio, Ltr., not uncommon on poplar trunks, very shy, and runs quickly 

 and hides in the crevices, refusing to jump, and is most difficult to catch. July — 

 August. 



Psocus quadrimaculatus, Ltr., very common on palings beneath trees, and also 

 on spruce firs. July -October. 



Psocus bipunctatus, L., four females on poplar trunks, 12.viii.04. I am 

 indebted to Mr. Morton and Mr. King for assistance in identifying this species, 

 which puzzled me. 



Psocus bifasciatus, Ltr., on spruce and other firs. July — August. 



Psocus fasciatus, F., on poplar trunks. June. This species jumps backwards 

 if the ends of its wings are touched. 



Psocus variegatus, F., in the same localities as the preceding, but occurs later 

 in the season. July — October. It is now fairly common in my garden, August 1st, 

 whereas I have not seen a fasciatus since June. 



Stenopsocus immaculatus, Steph.,on various trees and shrubs, common. June — 

 September. 



Stenopsocus cruciatus. L., common on various trees and shrubs. June — 

 September. 



Cxci/ius flavidus, Steph., common by beating, occurs on various trees through 

 the season. 



Cxcilius {ohsoletiis group), two or three species? on firs, &c., but so far 

 I have not mastered the characters of this obscure section, and want more fresh 

 examples to help me in so doing. 



Cxcilius pedicularius, L., not uncommon on various trees. 



Cxcilius dalii, McL, Holly near Chobham, ll.vii.04. 



Peripsocus alhoguttatus, Dhlb., on mint in my garden, lS.viii.04. 



Peripsocus phceopterus, Steph., common on all sorts of trees and shrubs 

 throughout the season. 



Ectopsocus briggsi, McL., common in many localities by beating, and among 

 dead leaves, &c. 



Elipsocus unipunctatus, Miill., common on various trees. July —October. 

 Elipsocus westwoodii, McL., not uncommon on firs, &c. 



Elipsocus hyalinus, Steph., not uncommon on firs, &c. 



Elipsocus fiaviceps, Steph., not uncommon on firs, &c. 



Elipsocus cyanops, Host., not uncommon on larclies. July — August. 



Clothilla picea, Motsch., I have seen this species once or twice in my house. 

 Atropos divinatoria, Miill., common in old insect boxes, &c.
