PLATE XXVII. 



Macropsis microcephala. (Page 95.) 



Fig. 1. — Winged form enlarged, and also of the 

 natural size. 



Macropsis lanio. (Page 95.) 



Fig. 2. — Female form, showing the horizontal stria- 

 tions on the pronotum. 



Fig. '2 a. — The same with expanded wings. 



Fig. 2&. — Head, showing the frons and clypens. 



Fig. 2 c. — The front view of the head, showing the 

 overhanging vertex and the insertions of the antennae. 



Fig. 2fZ. — The elytron and wing. The former is 

 inconstant as to the numher of apical cells. 



Fig. 2c. — Part of the saw {s), the outer sheaths {h), 

 and the lower plate at k. 



N.B. — Although it has been shown by the details on 

 many plates of this Monograph that all the Tettigidae 

 are, as to their tarsi, trimerous, it has not been easy so 

 to show them on the representations of the coloured 

 complete insects. It happens in many cases, that 

 unless the foot be viewed in profile and with a deep 

 lens, on account of the mergence of joints, the insect 

 may appear under the camera lucida to have only 

 two, instead of three, tarsal joints. Therefore in all 

 cases of detail of wing-veining, or of antennal or 

 pedal significance, the highest authority must be given 

 to such details, for as a rule distortions will not here 

 occur through perspective, or the errors liable to stone 

 colouring be so marked. Details for tarsi may be seen 

 in almost all of my former plates.
