averse to damp spots also. The most striking point in its economy 

 is the fact that it hibernates as an imago and reappears earlj^ in the 

 spring or even on warm bright days in the winter. Its sturdy 

 build, and pronotum reaching to, but scarcely beyond, 'the hind 

 knees, distinguish it from the much scarcer T. suhidatus. The two 

 black spots on the pronotum, from which it derives its specific 

 name, are not at all constant. (Figured in "Entom.," Vol. xxxiv., 

 PL III.) 



Tetrix subulatus, Linn. — In Europe this species appears to 

 have a more southerly distribution than the last. In England I 

 have a few records for the southern halt of the country, and there 

 is a somewhat doubtful one for Ireland. I have seen specimens from 

 the New Forest and Milton in Hants (Lucas) ; near Studland in Dorset 

 (Yerbury); and Padstow (Lamb) and Wildermouth Bay (Bracken) 

 in Cornwall. Other localities are East Grinstead Tind Dormans in 

 Sussex (Burr); Charmouth in Dorset (Shaw) ; Bickleigh Woods in 

 Devon (Bignell's Coll.) ; Burwell, Wicken, and Tuddenham Fens 

 (Morley). A few other records seem to me to need confirmation. 

 Apparently this species likes damp spots and may-be has a preference 

 for the neighbourhood of the sea. Whether it hibernates or not 

 seems not to be known ; presumably it does. It may be known 

 from T. bipitnctatus by (i.) its more slender build, (ii.) the pronotum 

 ■extending much beyond the hind knees. (Figured in " Entom." 

 Vols. X., xxiv., Pi. ill. and xliii., p. 327). 



Several casuals have occurred from time to time : — 



Gomphoceriis sibiriciin, Linn., once near Netley. 



PachijUjlns miiiratorim, Linn., possibly. 



P.danicns, Linn. (==cinerascens), occasionally, 



(J'Jdipoda crrridesccns, Linn., once or twice. 



Acridiinn (eiiyptiiun, Linn., occasionally, imported with vegetables. 



Schistocerca peref/riua, Oliv., occasionally. 



P. wi(/ratorii(s, P. daniciis, and .S\ pen'i/rina are migratorv locusts, 

 and flights may occasionally extend as far as Britain, as one of the 

 last-named did in 1869. P. daniciis is, however, most likely to come, 

 and may occasionally breed here. It is quite possible that P. mir/ra- 

 toriiis should always be P. daniciis, the identification having been at 

 fault.
