S. parallelus (Zett.). *Common in several localities in the

Gomphocerus maculatus, Thnb. (biguttatus, Charp).

 and rocks of Dovedale and Lathkill Dale, September, 

 1903 and 1904 (F.J.). 



OZdIPODIDjE. 



[Records of the two following species must be accepted with 

 some reserve, as in many cases locusts have been 

 recorded as P. migratorius without any attempt having 

 been made to determine the species. There appears 

 to be some question, too, as to the species figured 

 by Curtis. See article in the Naturalist, 1877, p. 129, 

 for further information.] 



Pachytylus migratorius (L.). One at Elton Moor, near 

 Youlgreave (Zoologist, 1848, p. 2001); three taken 

 and another seen recently in the neighbourhood of 

 Burton, Sept., 1857 (Zool., 1858, p. 5919); has been 

 captured in the winged state many times in this dis- 

 trict within the last twenty years (E.B.). 



P. cinerascens (Fb.). A male of Locusta christii on 

 Aug. 27th, 1842, near Derby (R. J. Bell, Zool., 1843, 

 p. 123). If this is correctly identified, probably the 

 locusts recorded as " Gryllus migratorius " in the 

 Zoologist for 1844, p. 478, from Stonegravels, near 

 Chesterfield (about the beginning of January, 1843) 

 and Burton-on-Trent (about mid-September, 1842) 

 also belong to this species. " I have one specimen 

 [perhaps the individual mentioned above] 

 taken near Burton " (E.B.)
