on them point in all directions. The other verrucae are mostly 

 elliptical with a long horizontal axis. The setae are arranged more 

 or less in one line, the middle seta is mostly the longest and the 

 others get symmetrically smaller in regard to this one. The longest 

 setae are born by the v. suprastigmales. The setae are not plumed. 



Prothorax. There is a small v. dorsalis, a very large v. suh- 

 dorsalis which is connected with the corresponding verruca of the 

 other side by a black coloured prothoracic shield. By this the 

 small 4). dorsales get united. Moreover, there is a rather large 

 V. suj>rastigmaliH which projects a good deal, a v. infrastignialis, 

 which has an offshoot pointing towards the dorsum, which per- 

 haps corresponds to the missing r. prostigmalis and a v. basalts 

 just over the beginning of the leg. 



Mesothorax and metathorax. There occur: v. dorsalis, v. dorso- 

 latemlis, a little larger than the v. dorsalis, v. supmsfigmalis, 

 V. infrastigmalis and a small v. basalts. The setae on these seg- 

 ments are shorter than those on the other. One might be inclined 

 to think that v. dorsolateralis owed its origin to the shifting of 

 r. subdorsalis. This verruca on the mesothorax and metathorax 

 is placed in front of v. dorsalis and on all the abdominal segments 

 V. subdorsalis lies behind it. Besides in other families the same 

 arrangement occurs as in this one, but then there is also a ver- 

 ruca or seta in the place where v. subdorsalis lies. For these 

 two reasons I think that the name of v. dorsolateralis deserves 

 the preference. (See Chapter IV). 



Abdomen 1, 2, 3, 4. There are a small v. dorsalis, a large 

 V. subdorsalis which is prolonged in a triangle towards the oral 

 side, beneath the v. dorsalis a v. siiprastigrnalis which has the 

 longest setae, a v. infrastigmalis and a small v. basalis. 

 Segm. 5. V. dorsalis is very small in some individuals and totally 

 absent in others, for the rest as on the abdomen 1. 



„ 6. V. dorsalis is very small and generally bears only one 

 short seta, for the rest = 1 . 



„ 7 = 1, In some individuals v. dorsalis has been partly 

 split into separate setae.
