COLEOPTERA. 281 



OLEOPTERA. 



Trogophl(eus suetilis, Er., in Durham. — In May last, when staying 

 with my friend Mr. Bagnall, I took a specimen of this rare species on 

 the banks of the Derwent at Winlaton Mill. During the same visit 

 Honialiinn (jracilicorne was taken under bark, and several Agathidiinii 

 hadium occurred. — Horace Donisthorpe. September 28tli, 1909. 



WicKEN Fen re-visited. — My friend, Professor T. H. Beare, and I 

 went to Wicken on September 14th for a few days, staying to collect 

 in the Fen. Our best capture, which was the chief object of our visit, 

 was of course Trechus rividaris, of which rarity three specimens were 

 taken after much hard work. The late Arthur Chitty is the only other 

 coleopterist who has taken it for many years. It occurred in sedge 

 refuse. In the same way we found Enconus hirticollis, Euthia scyd- 

 viaenoides, not uncommon, Neitraphes carinatus, Agathidiinii laevigatum, 

 Bythinus bulbifer, Conurus pedicularis, common, and inimaculatus, 

 Stilicna fragilis, in numbers, llyobates nigricollis, Eiiplecttis anibigiiiis, 

 Anchomenus livens, Stenus lustrator, binotatus, pabistria common, 

 exiguus, fuscijjes, and pnsillus, Lathrobinm, fovuliim, and filiforme^ 

 Hypocyptiis apicalis, Evestethus scaber, Silpha atrata ab. brimnea, etc., 

 etc. Sweeping in the fen produced Chrysomela grawinis, Stilbus oblongus^ 

 Phalacriis caricis, Galeruca cahnariensis, Longitarsiis castaneus, L. 

 fiavicornis, and Chaetocnema cnnfasa, in some numbers. Cassida vibex 

 was swept off thistles, and Longitarsiis ballotae was beaten off Ballota 

 nigra. With the latter occurred specimens of what must be a 

 curious small form of Psylliodes affinis. They are rather pale, and 

 strongly superficially resembled the Longitarsiis. No Solanum, the 

 proper foodplant of the L-'sylliodes, could be found anywhere near. — 

 Id. 



The Genus Apion. — Having this year taken Apioii stolidum near 

 Oxford in June, and at Ditchling with my friend Mr. Dollman in 

 September, and Apion affine in the latter locality, I have now taken 

 the whole genus myself, excluding, of course, the two doubtful species 

 opeticinn and ryei. As this is probably a record for any one single 

 individual, I propose to write some notes on the subject later on. — Id. 



Coleoptera near Cambridge. — In the neighbourhood of Byron's 

 Pool, Grantchester, two or three nice wood-frequenting species were 

 to the fore. The most productive tree worked was a broken-up and 

 much decayed elm ; this produced Xantholinus glaber, Nord., Quedins 

 scitus, Grav., Symbiotes latns, Eedt., Dendrophilns punctatus, 111., and 

 a fine form of Quedins mesomelinus, Marsh., the thorax, elytra, and 

 abdomen being of a pitchy-red colour. From a dead ash (killed by 

 T>aucus) near Madingly, Llypophloeiis bicolor, 01., Dacne humeralis, F.,. 

 and Mycetophagiis multipunctatas, Hellw., were taken. The Dacne 

 and Mycetophagiis occurred in great profusion among Boleti, within 

 the hollow trunk. Around the margins of a large pond near St. 

 John's College " backs," a very large number of beetles were found. 

 The most interesting of these was undoubtedly the very rare Barpalus 

 obscuriis, F., one specimen of which was shaken out from decayed grass 

 refuse in early May. Other interesting species were Panagaeus crux- 

 maior, L., rarely at grass roots, Stenolophus skrimshiranus, Steph., in 

 large numbers among debris close to the water's edge, Deinopsis erosa, 

 Staph., not uncommon, taken by immersing grass roots, Coccidulascutel-
