Table of Genera. 



1. Elytra lobiform, wings absent Loboptera, Brunner. 



1.1. Elytra and wings fully developed Phyllodromia, Serville. 



Genus 1 : Loboptera, Brunner. 

 This genus has a single European species which is oblong, apterous, 

 dhining black, bordered with whitish. In appearance it resembles 

 some species of Aphlebia, but is distinguished by the form of the anal 

 apparatus of the S ? and of the ootheca, or egg-case, which is rounded 

 and flattened, and not arched and keeled. 



1. Loboptera decipiens, Germar [ = iunbata, Charpentier). 



This species has the length of body, 8mm. <? , 11mm. ? . 



Common under weeds and stones on the coast from Portugal to 

 Asia Minor. In the south of France it is common all the year round, 

 and occurs throughout the Iberian Peninsula. 



Genus 2 : Phyllodromia, Serville. 

 Elytra and wings fully developed ; latter with no clear folded 

 triangular area at the apex ; seventh dorsal segment of abdomen 

 depressed, hollowed ; supraanal plate produced ; subgenital lamina 

 produced, emarginate on the left side, and furnished with a short style. 

 In the $ the abdomen is much broader, the three last dorsal segments 

 narrow, the subgenital plate ample and broad. The oothecae are 

 smooth, long, not keeled, but with rounded edges. 



Phyllodromia germanica, Linn. 



Easily known by its shining tawny colour, and with two longitudinal 

 black stripes on the elytra. Length of body, 18mm. <? , 11mm. ? ;

This species is well known as a household pest ; it occurs in houses, 

 hotels, restaurants, in many towns in Europe. In Russia it is called 

 the "Prussian," and in Prussia it is known as the "Russian." It 

 seems to be commoner in eastern, than in western, Europe, but is now 

 spreading everywhere. In America it is the pest known as the Croton 

 Bug. It occurs in a wild state in north-eastern Europe, as far west 

 as Thuringia and Saxony, the Hartz Mountains, and Westphalia, and 

 also at Kloster Neuburg, near Vienna. 



Family III : BLATTiDiE. 

 Distinguished by the anal parts ; in the <? the supraanal plate is 

 produced, transverse, sometimes bilobed ; the cerci are long, and the
