HOMOPTERA, 297 



lows it Heteroptera ; also an order containing insects 

 with thickened wings, and, like Homoptera belonging 

 to the Sucking section, like it possessing an evident 

 beak or rostrum. And here the wings themselves, 

 apart from all considerations of veining (which is 

 very various in both these orders), afford sufficient 

 distinction. 



HOMOPTERA (from ojuotoe, homoios = alike, and TTTC/OOV, 

 a wing] contains Sucking insects in which the fore-wings, 

 whether thickened or membranous, are of a uniform 

 texture throughout .(see PI. XII., figs. 1 to 6). Thus 

 they may be thickened, as in the Frog-hopper (and so 

 differ from the hind- wings, which are clear), or, with 

 the hind-wings clear, and consisting throughout of thin 

 membrane, as in the Aphis. In HETEROPTERA (from 

 2r/30, different, and irrtpov, a wing) a reference to 

 PI. XIII. will at once show that the fore-wing displays 

 two distinct textures. 



This, however, is not the only nor the chief difference 

 between Homoptera and Heteroptera (although the 

 distinctive names are derived from it), and indeed, 

 while this was considered as the chief distinction, the 

 two were combined in one order under the name of 

 Hemiptera.* 



The remaining characters of Homoptera are as fol- 

 lows ; those of Heteroptera will be found in their place 

 farther on : 



The insects are stout-bodied, sometimes with very 

 long, but generally with short, awl-like antennae, from 



* The reader will do well to remember this, as the name Hemiptera 

 frequently occurs in books both old and comparatively new, and might 

 cause some confusion in his mind.
