its occurrence at Llanberis. 1 find I look a male there several years ago, probablj 

 from the wet moss ill the river noar the watorfall. Tliis sex can readily be rlistin- 

 guishcd by tlic very distinct angular diliitatioii of the posterior tibise ; the female I 

 should imagine it would be rather difficult to separate from some forms of H. 

 riparia, Kug. — W. E. Sharp, South Norwood : October Qth, 1007. 



Coleoptera in Surrey and iTart^?. —Among my captures during the past spring 

 and summei — and to some extent making up for a very poor season's work — are : 

 Odontitis mobiliccrnis, F. ; this specimen caused groat consternation at a tennis 

 party a( Woking by alighting on a fair player ; luckily for me a friend (who knows my 

 " eccentricity ") captured the insect and presented it to me. HaUomenus humeralis, 

 Panz., this I took as it was running on a cement path in my garden. Csenopns 

 fixsirostris, Walt., this I obtained by sweeping at Lyndhurst in June. When at 

 Lyndhurst Mr. Tate, Jun., gave me a specimen of Pissodes notatus, F., in splendid 

 condition, which he had taken in the Forest. Callidinm variabile, L., a very small 

 ppecimen was obtained at Petersfield.— Lewis F. Barton, The Retreat, Guildford 

 Road, Woking : September 26th, 1907. 



Peritrechiis gracilicornis, Put., and other Hemipfera and Coleoptera in the Isle 

 of Wiffht. —Whiht collecting Tlemiptera in the Isle of Wight during the first 

 fortnight in August, I had the good fortune to find a specimen of Peritrechus graci- 

 licornis. Put., on Pan Down, near Newport. The insect might easily be passed 

 over in the field as P. geniculatus, as the differences are mainly comparative, the 

 chief being the somewhat larger size and the thinner antennae of _5rrae«7Jco.-»«. This 

 capture is interesting as being the second British record of the species, the only 

 other being by the late Mr. Douglas many years ago at Hastings. Other interesting 

 species which occurred to me were Sehirus morio, L., several larvse in a gravel pit 

 on St. George's Down, near Newport ; Neides tipularius, L., in the same place ; 

 Nabis boops, Schiodto, under heath in Parkliurst Forest ; Brachi/steles parincornis, 

 Cost., running on the damp ground amongst scantily growing rushes at Totland 

 Bay ; Calocoris seticornis, F., several by sweeping long grass, &c., on the cliffs of 

 Sandown Bay ; C. ticinensis, Mey., in Rookley Wilderness. On examining a num- 

 ber of specimens of Orthotylus marginalis, Rent., chiefly from the neighbourhood of 

 Freshwater, I find that the g of this species has the basal joint of the antennae 

 dark at the base, and sometimes almost entirely infuscate. Mr. Edward Saundei*s, 

 whose attention I called to this, has asked me to point out the necessary modification 

 that must be made in the description of this species in his " Hemipt.-IIeteropt. of 

 Brit. Is.," where it is stated that the basal joint is pale in both sexes : this should 

 apply only to the ? . 



Amongst the Homoptera the most interesting were Oliarus leporinus, L., in a 

 salt marsh at Yarmouth ; Cixius scofti, Edw., Sandown Bay ; Ledra aurita, L., a 

 very young larva in Parkhurst Forest ; Pediopsis nanus, H.-S., and Stictocoris 

 pretfssleri, H.-S., on Freshwater Down ; Deltocephalus strii/rons, Kb., on Pan 

 Down. In the salt marshes at Yarmouth I also found a number of specimens of a 

 doubtful Athysanus, which is near obsoletiis, Kb., but differs from inland examples 

 of that species in having a longer and more pointed crown, and a differently marked 

 frons. This form is ill under investigation by Mr. Jas. Edwards.
