4 THE ENTOMOLOGIST. 



In all three countries there occur of the Acridiidge, Meco- 

 stethus grossus, Stenohothrus viridulus, S. rujipes, S. bicolor, S. 

 elegans, Gomphocerus maculatus, OEcUpoda ccerulescens (only as a 

 very casual visitor in Britain), Tettix hipunctatiis, and T. suhidatus, 

 while Pachytylus migratorius is a casual visitor to each. Steno- 

 bothi'us lineatus, S. parallelus, and Gomjjhocerus rufus are com- 

 mon to Britain and Belgium ; while Stenohothrus higuttulus, 

 Pachytylus danicus {cinerascens), and Psophus strididus are 

 common to Belgium and Holland. Gomphocerus sibh'icus, 

 Acridium (egypticum {tartaricum), and Schistocerca peregrina 

 have occurred casually in Britain alone ; Stenohothrus stig- 

 maticus, S. hamorrhoidalis, S. vagans, and S. dorsatus are found 

 in Belgium only ; Holland possesses none that are peculiar to 

 itself. 



One specimen only of Gomphocerus sihiricus was captured 

 some years since " on the hills at Netley " ; it is difficult to 

 imagine how a single specimen could have got there. 



Of the fifteen Locustidse enumerated by De Selys-Long- 

 champs, Leptophyes punctatisswia, Meconema varium, Xiphidium 

 dorsale, Locusta viridissima, Platycleis grisea, P. hrachyptera, and 

 Decticus verrucivorus are found in all three countries. Thamno- 

 trizon cinereus and Platycleis roeselii are found in Britain and 

 Belgium ; Ephippigera vitiuin occurs in Belgium and Holland. 

 Barhitistes serricauda, Gampsocleis glabra, and Platycleis bicolor 

 are peculiar to Belgium ; while Phaneroptera falcata has occurred 

 casually once and Decticus alhifrons very rarely, in Britain 

 alone. 



Four species of the Gryllidse — Nemobius sylvestris, Gryllus 

 campestris, G. domesticus, and Gryllotalpa vidgar is -occur in all 

 three countries. Gryllus capensis is found in Holland only, 

 while G bimaculatus, G. hrunneri, and Gryllotalpa didactyla are 

 casuals in Belgium alone. 



To sum up as far as Britain is concerned, there are twenty- 

 nine (or twenty-eight if Decticus verrucivorus is omitted) Ortho- 

 ptera that appear to be natives ; * seven (two earwigs, with but 

 a slight foothold, four cockroaches, and the common cricket), 

 which breed here in warm houses ; three earwigs that are more 

 or less historic ; the rest are casuals. These last might no doubt 

 be added to considerably. Burr states that some species of the 

 Conocephalides, especially of the genera Cojnophora and Cono- 

 cephalus, have been taken in London. A specimen of Phane- 

 roptera privata has been found at Merton Hall, in Norfolk. I 

 have in my own possession five Orthoptera from Kew Gardens 

 not included in the list. One of them is probably Copiophora 

 hrevirostris ; the others are not yet identified, but the presence 

 of all is of a most casual nature. 



'''- Burr considers D. verrucivorus, A. albipennis, and L. riparia to be 

 indigenous.
