appears to consist only of chitinous remains of insects, per- 

 haps mostly beetles. The intestine is arranged in short coils 

 aloiig a very simple mesentery as approximately is sketched 

 on the accompanying figure (fig. 6), in which, however, the 

 duodenum (to the left) is covered by other coils and not 

 visible. The last part of the intestine runs quite straight 

 and is attached with a very short mesentery. On that 

 straight portion not quite 2 cm from the opening of the

duodenal tract is not, however, visible and 



a part of rectiim is cut avvay. 



cloaca sits on the left side a small and simple caecum. It 

 has its blind end directed forwards and measures 4—5 mm 

 in length. By means of microscopical sections it has been 

 stated, that it is rather thickwalled, and that the walls con- 

 tain rather muoh fatty tissue. This accounts also for the 

 somewhat whitish colour of this organ. 



The shape of the spleen is shown by the figure (fig. 7). 

 It is elongate, almost tongue-like with the cardiac (left) end 

 rounded off. and the duodenal end broader and more trun- 

 cate and with the dorsal corner somewhat produced in a lobe.
