CYMID.E. 235 



base ; their course is at first straight and parallel ; they then turn 

 suddenly outwards for a short distance, and again resume their course 

 to the posterior margin ; at the angle thus formed in the centre of 

 the membrane, the other 3 nerves arise from a common point 

 and radiate outwards. Sternum; Mesosternum with a rounded 

 rostral channel, which is also continued, but more narrowly, across 

 the metasternum. Legs short ; ihiglis a little thicker in the middle ; 

 tarsi ; last joint thickest, as long as the 1st. 



Abdomen beyond the 5th segment gradually narrower ; in the $ 

 the posterior margin of all the segments is straight ; in the ? , the 

 4th is from the connexivuin inwards gradually shorter, so that in the 

 centre it is just visible ; the 5th is similarly shortened, and in the 

 centre passes under the 4th segment ; the 6th segment long, sloping 

 flatly outwards from a ridge in the centre; the anterior and posterior 

 margins parallel. Connexivum broad. Genital segments ; in the 

 , beneath, 2 are visible, of which the 1st is only perceptible in the 

 centre ; the 2nd much narrower than the last abdominal segment, 

 but globose and prominent, forming a rounded end to the abdomen ; 

 in the $ , above, 2 are visible ; beneath 3, deflected to the apex with a 

 ridge down the centre ; the 1st placed in the centre of the angle of 

 the last abdominal segment, is posteriorly angulated, and reaches 

 over on the large convex 3rd segment which has a slight fissure in 

 the centre, is posteriorly constricted at the sides and ends in an ob- 

 tuse point ; the 2nd appears at the anterior margin of the 3rd as a 

 narrow, long, angulated plate, of which the apex goes under the 1st.
