own do not coincide, showing how dangerous it is to generalize on the 

 capabilities of any district from one flying visit. The discrepancy 

 may probably be accounted for in more than one direction. July and 

 the beginning of August are too early for Psocidce generally ; the 

 season of 1901 may have been damper (these insects like a, certain 

 amount of moisture, as favouring the growth of the minute fungi on 

 which they principally feed) ; and, Anally, the localities were not in all 

 respects identical. Mr. Eaton brought from the district precisely 

 double the number of species that 1 found, in at least 35 specimens, 

 and it is fair to assume that he made no very special search for them. 

 The species he found are as follows : — 



Psocus (Amphigerontia) bifasciatus, Ltr. (1), Brassus, August 16th. 

 Ps. nebulosus, Steph. (4), Yallorbe, August 13lh, and Brassus, August 17th. 

 Ps. longicoknis, L, (0), " Source de l'Orbe," August 13th. 

 Ps. sexpunctatus, L. (4), Cascade du Bay, August 12th, and Brassus, 

 August 17th. 



Stenopsocus immaculatus, Steph. (1), " Source de l'Orbe," August 13th. 



Elipsocus (Mesopsocus) unipunctatus, Mull. (1), Brassus, August 17th. 



E. iirALiNcrs, Steph. (1), Brassus, August 10th. 



E. (Philotaesus) flaviceps, Steph. (many), Brassus, August 16th and 17th. 



Cecilius Bubmeisteki, Brauer (2), " Source de l'Orbe," August 13th. 



C. peklatus, Kolbe (1), Brassus, August 17th. 



Of the foregoing only Ps. longicornis and M. unipunctatus were 

 found by me ; Ps.fasciatus, St. cruciatus, and E. abietis were found by 

 me and not by Mr. Eaton. It may be taken for granted that many 

 more species will be discovered in the district when it is systematically 

 worked. 



A Swiss entomologist, Herr Eric Mory, of Basel, visited the 

 district in August, 1898. He made important captures in Odonata, 

 but does not appear to have found any Psocidce (cf. Mitth. schw. 

 Entomol. Gesellschaft, x, pp. 187—197). 



Lewisham, London :

Coleoptera caught in Ireland during Mag and June, 1902. — On May 19th I 

 visited Greystones, near Bray, but did not secure many beetles worth mentioning : 

 Chrysomela Banksi was common under stones, and a short series of Barypeithes 

 sulcifrons and a single specimen of Barynutus ISch'6 nheri were obtained by sweeping. 



On the advice of Mr. J. N. Halbert, to whom 1 am much indebted for his 

 kindness in showing me the best localities, I worked the North Bull, a sand bank 

 near Dollymount, where 1 succeeded in capturing several nice species ; Aepus 

 marinus occurred in abundance under the stones of the breakwater, and with them
