NOTES ON A FEW ORTHOPTERA. 22? 



distinction, but these are the most noticeable. E. tcrifi'ntivn, Muhlf., 

 is quite a distinct species ; the bhie posterior tibire, with a black ring 

 at the apex and base at once distuiguish it from E. strepenH and 

 E. thalasxina, in which the posterior tibife are red. E. taiindua, 

 Fabr., perhaps better known under the synonym, tricoloripes, Burm., 

 is one of the most widely distributed species in Asia and Australia.] 

 In two of these specimens from Cannes the wings are tessellated 

 with yellow : this is not noticed in the descriptions given by Brunner 

 and by Finot. 



Oedipodid^. — Avrotijlua insnbricus, Scop. — One male, one female, 

 Cannes, March, 1897. One female, Digne, April 26th, 1897. This 

 extremely pretty little species is common enough in the south of 

 Europe, round the shores of the Mediterranean Sea, the north 

 of Greece, Provence, Pesth, Volga, and also in Asia Minor and 

 Algeria, In the south of France it seems to be fairly common, and 

 was observed by Dubrony to hybernate, and appear in the following 

 spring, which these specimens had evidently done. As in other 

 Oedipudidai', the colour of the wings varies. Brunner records 

 specimens from Aleppo, in which the red of the wings fades into 

 yellow ((•/(/(', Proc. Ent. Soc. Loud., 1897, p. xv.). [There are two other 

 European species: (1) A. lomjipefi, Charp., in which the wings are 

 yellow hyaline at the apex, and there is no black fascia. (2) A. 

 patrudis, Sturm., is closer to A. inmbricn^, but differs by its smoother 

 pronotum, which is constricted in front and rounded behind. In 

 A. insuhricus the pronotum is not constricted, and is pointed behind, 

 and the dorsal aspect is rugose ; the antennje are much longer in 

 A. patnicUs than in A. insubricus.~\ 



Pcir/ii/ti/lns cint'i-ascciis, Fabr. — One female, Cannes. This species 

 is an inhabitant of western and northern Europe ; it is connnon in 

 the south of France, and by reason of its large size and comparative 

 al)undance, sometimes causes some mischief in gardens. It is also 

 found in Spain, Italy, Dalmatia and Greece, but has further an 

 extraordinarily wide distribution, no doubt caused by its great powers 

 of flight. Outside Europe it is found in the Canary Islands, all North 

 Africa, Egypt, Asia Minor, Syria, Mauritius, Java, Japan, Philippine 

 Islands and New Zealand. It is often mistaken for P. luif/ratoriiis, 

 L., from which it dift'ers as follows : the pronotum is produced to a 

 blunt point anteriorly and posteriorly, whereas it is rounded in P. 

 iiiiliraturiun ; the posterior tibiae are reddish (livid or yellow in P. 

 iiuiiratnrim) ; the pronotum is more raised in this species than in 

 mii/ratormfi', in cvwrasci'iis the male is considerably smaller than the 

 female, but the sexes are about the same size in P. miijratoriux. 

 P. mi;iiatorius is an Eastern species, and very rarely straggles as far 

 westward even as France. P. cineraacens has even been confounded 

 with Scliistocerca pert'iirinn, Oliv., a very distinct species, that may be 

 at once distinguished from the Oedipodidac by having a distinct 

 tubercle on the prosternum. In the south of France, P. cincrascenH 

 often hybernates and appears in the spring ; the eggs that are laid in 

 the beginning of the year soon hatch, and the insect is adult in 

 autumn. 



AcRiDHD.E. — Acridiu))! iu'iniptinm, L. — One male and two females, 

 Cannes, March, 1897. This tine species is common in the Medi- 

 terranean region, and, like the last species, has straggled to England,
