256 the entomologist's record. 



with me one day, and I was able to show him the Chelifer in the 

 nest. I have since taken it, with F. rufa at Buddon Wood. 



Lepidoptera. — Tineina. — I bred two little moths from my Formica 

 exsecta nest from Bournemouth. Mr. Eustace Bankes tells me they are 

 certainly distinct from all our known British species of Gelechiids, 

 and perhaps new to science. 



Polyommatus icarus. — Mr. A. L. Bayward has shown that this 

 species, like Lycaena avion, Agriades corydon, and Agriades bellargns, is 

 possessed of a gland which secretes a fluid very attractive to ants. 

 (ait tea, p. 103). 



Agriades corydon. — Mr. Bayward having kindly sent me two larvae 

 of /'. corydon, I introduced the following ants to them : Formica rufa, 

 L . sanguined, F. e.csecta, F. fusca, and Lasius fidiginosus. The 

 larvae were put into plaster nests with glass tops, and six or eight 

 specimens of an ant put in with them. Most lepidopterous larvae, 

 under these circumstances, are attacked and killed, and I often use 

 them to feed my ants, but such was not the case with these larvae. 

 One Formica sanguinea seized a corydon larva and dragged it along a 

 little way, the caterpillar remaining quite rigid, but soon dropped it, 

 and all the ants mostly sat on the larva at different times, tapping 

 the posterior part of the body with their antennae. I left the 

 caterpillars with a species of ant for a week at a time, and I put one 

 into my F. rufa nest itself, where it crawled about among hundreds of 

 ants without coming to any harm. 



Acarina. — Trachyuropoda laminosa, C. B. — I took this species with 

 Lasius flavus at Whitsand Bay, in April. 



Trachyuropoda boatocki, Mic. — I took this large and rare species in 

 some numbers in nest of Lasius umbratus at Whitsand Bay. 



Urotrachytes formicarius, Lubb. — I took it with Lasius jiacus in 

 June, on Arthur's Seat, Edinburgh. 



Trachyuropoda excavata, Wasm. — I took this species, which is new to 

 Britain, and recorded for the first time here, with Lasius fidiginosus at 

 Sherwood Forest. 



Urodiscelia ricasoliana, Berl., was taken with Lasius fuliginosus in 

 Sherwood Forest. 



Laelaps myrmecophylus, Berl., was taken with Formica ru/ibarbis 

 var. fusco-rupZbarbi-s, in plenty, at Whitsand Bay. 



Laelaps equitans, Mic, was taken in nests of TetramoHum caespitum 

 at Whitsand Bay. The mite rides on the ants, jumping off and on as 

 they run along. 



Laelaps cuneifer, Mic. — I took this species with Formica rufa in 

 some numbers at Weybridge, in May. 



Laelaps oophilus, Wasm., a new species to Britain, was taken on and 

 among the egg-masses of Formica fusca at Porlock, and of F. rutibarbis 

 var. fusco-rufibarbis at Whitsand Bay. 



Antennophorus grandis, Berl. — This interesting species was found 

 in plenty at Porlock, and in Sherwood Forest with Lasius fuliginosus. 



Cillibano comata. — This species, new to Britain, was taken in plenty 

 on the larvae of Lasius flavus at Whitsand Bay. 



Myriapoda. — Blanjulus guttulatus was bred out of my observation 

 nest of Formica exsecta in some numbers this year.
