CASUAL SHORT-HORNED GRASSHOPPERS, ETC. 



Gomphocerus sibiricus Linn. One specimen, in the Hope Collection 

 at Oxford, " was captured on the hills near Netley." Being a native 

 of South and Central Europe, and of Asia, it is scarcely likely to have 

 been anything more than a casual. It may be recognized by (i) its 

 swollen fore tibiae, (ii) its unicolorous antennae, and (iii) its being 

 without spots. 



Pachytylus migratorius Linn, and Pachytylus danicus Linn. (= 

 cinerascens Fabr.). These are migratory locusts, which occasionally 

 straggle as far as the British Isles (and of course may also be 

 introduced casually). There is, however, much confusion in the 

 records of the two. In some years 1842, 1846, 1847. 1857, 1876, 

 etc. flights seem to have reached us. Though many have been 

 recorded as P. migratorius, probably most were P. danicus, the former 

 inhabiting Eastern Europe, while the latter is a resident in France, 

 if not in Belgium. The following points may assist in separating the 

 two species : P. migratorius has the pronotum rounded, and not much 

 raised ; hind tibise yellow or livid ; size about the same in both sexes. 

 P. danicus has the pronotum ending, both before and behind, in a 

 blunt point, and more raised than in the other species ; hind tibise 

 reddish ; female considerably larger than the male. Moreover, as
