226 The Irish Nattiralist. [Sept., 



and received by me from many Irish localities, and apparently 

 generally distributed. There were two species of Didyiiidce. 

 — Didyna u7icinata, Thor., and D. latens, Bl. ; I do not think 

 that the latter has'ever been recorded from Ireland, though Mr. 

 Freeman first took it near Dublin several years ago. No 

 representative of the AgelaiidcE was secured. 



The small Theridiidcs, which comprise the majority of our 

 spiders, are not numerous in June. Theridion sisyphium, CI., 

 was common, as might have been expected. Linyphia mon- 

 tana, CI., — a species that with us seems to be found in parks 

 and gardens — was taken in the demesne, together with L. 

 pusilla, Sund., L. horte?isis, Sund., Labulla thoracica, Wid., 

 Leptyphantcs tenuis, Bl., and L. Blackzvallii, Kulcz. The com- 

 mon species Erigone atra, Bl., and Go7iatiiim bituberculatum, 

 Wid., were also secured, as well as the tiny Maso Sundevallii, 

 Westr. The only other theridiid taken was one of the prizes 

 of the expedition — Coriiicularia vigilax, BL, a ver}' rare species 

 in the British Isles, found only in Dorsetshire and North 

 Wales\ with a wide but discontinuous continental range from 

 France to Galicia-, and occurring also in the United States. 

 Both sexes of this species were secured by Halbert, a male at 

 Doon and a female in the demesne. 



Six species of the EpeiridcB or orb-weavers were collected. 

 Besides the common Tetragnatha extciisa, ly., Halbert secured, 

 by sweeping heather on Sheep-pool Bog, a female of T. obtusa, 

 C. Koch, a species with less elongate abdomen, hitherto 

 unknown as Irish. Since determining this spider, I have 

 found another female in a collection sent me last year from 

 Skibbereen, Co. Cork, by Mr. J. J. Wolfe. As might be 

 expected, Ilfeta segmcntata, CL, Epeira diadcmata, CI., and E. 

 cormcta, Cl.> were common. The other epeirid taken, Singa 

 sangidnea, C Koch, is a valuable addition to the Irish list; 

 being rare in Great Britain, and apparently confined to the 

 southern counties^. 



Th-ere were three Thomisidce or crab-spiders: — Philodromus 

 aureolus, CI, and Xysticus cristatus, CI. — both common species 

 everywhere — together with another addition to the Irish 

 fauna, also found by Halbert on Sheep-pool Bog — X. sabulosus,
