GUIDE TO THE 
Next follow the 
Rhynchota. 
Some of these, like the Flatinae and several of the 
“ Lantern-Flies,” Fulgora, rival the Butterflies in the 
brilliancy of their colours, while others, the Cicadidae, 
are famous for the noise they produce, which in a 
Venezuelan species is as loud as and as similar to 
the whistle of a railway engine as it can possibly be. 
The males only produce the “ song,” the females 
being without the sound-producing apparatus. The 
Fulgora or Lantern-Flies were believed formerly to 
possess luminous properties, but modern observers 
have not conflrmed this. To this order of insects 
belongs also our European Water-Scorpion, Nepa 
cinerea, and a number of gigantic American Nepae. 
These fly well and are often attracted by the light, 
a fact from which they have received the name 
“ Electric-light Bug.” Other more objectionable 
members of this order are the Bed-Bug, Cimex 
lectularius, and the Phylloxera of the vine. 
The order 
Oirthoptera 
includes the Pseudoneuroptera, i.e. the Dragon-Flies, 
May-Flies, White Ants {Termes), and the true 
Oi'thoptera, i.e. the Grasshoppers, Locusts, Crickets, 
Cockroaches, and allies.
