[July, 



tarsalis, oculatus, hrunnipcs, fulvicornU, luplifhahnns (novr almost extinct) and 

 cicindeloides, — the last-named in myriads. Evcesthetus Iceviuaculus and ruficapilhis, 

 StilicHs geniculatus and orhiculatus, Tachyporus solutus and scitulus, Myllceno. 

 hrevicornis and minuta (hard to get and harder to set), the common marsh Quedii 

 and Trogoplilcei, Lesteva punctata, fmA VMlonthus varius, var. hipustulatus^ cinerascens 

 and signaticomis, complete the note-worthy Brachelytra. P. signaticornis seems 

 very rare : it occurs in matted grass-roots, and may be known from villosulus by 

 the usually darker base of its antennae, its darker legs, and its duller, because more 

 closely punctured, elytra and abdomen. Of the Geodephaga, Stennlophus Terdonus 

 s.nd Anchonienus atratus are the best ; and of the Rhynchop1iora,Erirhiniis sc^l^rrhos^ls 

 (not uncommon), Pachyrinus comari and the black-necked Cionus verhasci : Hydro- 

 novius, Phytonomus pohjgoni and pollux (as at Hammersmith marshes, accompanied 

 by its plainly striped form), and other vulgarities abounding. Donacia sericea, 

 Telmatophilus caricis, ChcetartJiria and Cyclonotum in swarms, Simplocaria, Praso- 

 curis heccahungcB (also not seen by me so near London before), Cassida ohsoleta, 

 Phyllotreta hrassicce, Corticaria denticulata and Bryaxis juncorum, though all common, 

 will help to swell the list. 



I have also found here what I suppose to be Limnehius papposus, conspicuous 

 for the inflation of the middle joint of its palpi. Of the authorities at my command, 

 I can only find mention in Redtenbacher of this peculiarity ; indeed, the equal size 

 of the joints of the palpi appears to be one of the generic characters of Leach's 

 Limnebius. 



In the Hemiptera I was surprised to find, commonly, the little enigmatic Hehrus. 

 This does not seem to have been observed near London before. Of some species of 

 Salda to be taken here, elegantula, readily to be known by the suddenly incrassated 

 apical joints of the antenna?, is not uncommon, with Monantliia humuli. S. Flori 

 occurs in grass at the edge of the Thames Bank ; the specimens with partially 

 yellow apical joints to their antennae being apparently varieties of the ? . 



On Wimbledon Common I was much pleased to light upon a little colony of 

 the strident Trox salulosus, in and under a very small and desiccated dead lamb. 

 This curious beetle, after foolishly giving notice of its whereabouts by its peculiar 

 squeak, shams death pertinaciously. The grass beneath a very small tuft of wool 

 harboured three specimens. In digging up the roots I found Corymhites hoJosericeiis, 

 just out of pupa, with its larva. The dry carcase above mentioned also contained 

 several of the pretty Nitidula quadripustulata , with other commoner carrion-feeders. 

 On the sallows I found Erirhinus salicis, plentifully; replaced in a week by Elleschus 

 hipunctatus. Apion viinimum and EpiLrcea melina also accompanied these species ; 

 and Oxy stoma genistoi was not uncommon on small spiny broom. In a marshy 

 place, not before examined, I took some Philontlnis nigriia, and P. sanguinolentits 

 with its elytral spots confluent ; and, at the old pond near the Mill, Tachyusa atra, 

 Stenus longitarsis, and a nest of Aleochara hrevipennis. When the small scattered 

 ponds here dry up, many Agabi, Hydropo'n, Hydrochi, &c.,are easily and plentifully 

 to be taken. In this way I have found Agahus nigro-cenexis, i^Iarsh., considered 

 specifically distinct from chalconotus hy continental authors, but not recorded 

 otherwise than as a var. of that insect in our modern lists. Hydropoinis lepidus is 

 particularly abundant here.
