Family IV. Empuside. 



Genus 1. Empusa, Illiger. 



The family is characterised by the lobiform appendages of the legs 



and abdomen. This genus, the only one occurring in Europe, has 



also a conical protuberance l)etween the eyes ; the antennae of the 



male are pectinate and the pronotum long and slender. Only one 



species is found in Western Europe. 



1. Empusa egena, Charpentier. 



Greenish, testaceous ; easily recognised by the peculiar form of the 

 vertex and lobed legs and abdomen. Length of body, 60mm. J , 

 67mm. ? ; of pronotum, 24mm. <? , 26mm. 5 ; of elytra, 4:0mm. 3 , 

 35mm. 2 - , 



Found in moist places in hot districts on shrubs and grass. It is 

 adult in May. Finot remarks that the larvte, which can be easily 

 reared on flies, are commonly kept as pets by invalids, on account of 

 their amusing antics. 



In France it is common in the southern parts; Provence, Toulouse, 

 Cannes, Hyeres, Tarbes, Medoc, Bordeaux, Toulon, Ollioules, Aix, 

 Caraman, Haute Garonne, Draguignan, Bagnols, Valence. In Spain 

 it is widely distributed, occurring as far north as Coimbra in 

 Portugal, and Longroiio, also Granada, Malaga, Madrid, Guadalajara 

 are given as localities. It occurs in Sardinia, and in Italy is recorded 

 from Florence, Sicily, and Serravalle and Scrivia in Liguria. 



Section III. Euorthoptera. 

 Division I : Phasmidea. 

 This group is represented in Europe by but two genera, closely 

 allied to each other, with very few species. 



They are herbivorous, sluggish and harmless insects, familiar on 

 account of their stick-like build ; the European genera are entirely 

 apterous ; the antenna? are somewhat thick and shorter than the 

 anterior femora ; the whole body is slender and cylindrical, and the 

 legs slender. 



Family I. Bacillid.e. 

 Table of Genera. 

 1 . Inteimediate and posterior tibiae with inferior carina 

 forked at the apex ; cerei j straight or slightly 

 curved at the apex ; abdomen ? not notably com- 

 pressed nor attenuated near the apex ; ova almost 

 globose . . . . . . . . . . . . 1. Bacillus, Latr. 



1.1. Carina beneath middle and posterior tibiae simple, 

 not forked at the apex ; cerci ,s dilated and toothed 

 at base, then curved ; abdomen ? notably com- 

 ipressed and attenuated near apex ; ova elongate, 

 oblong .. .. .. .. .. ..2. Leptynia, Pantel. 



Genus 1. Bacillus, Latreille. 

 In this genus the carina under the middle and posterior tibife 

 is forked at the apex, forming a small triangular area. Only two 

 species occur in Western Europe.
