PLATE XXXVII. 



Tettigonia viridis. (Page 124.) 



Fig. 1. — The female. The elytra show then- 

 Hemipterous character in the semi-membranaceoiis 

 texture of their apices. 



Fig. 2.— The male insect seen in profile. 



Fig. 3. — The head, pronotiim, and scutellum of the 

 female. The tumid cliaracter of the vertex, the pig- 

 mental spots of the eyes, and the situation of the 

 ocelli are here well marked. 



Fig. 4. — Frons and clypeus, the former striated. 



Fig. 5. — An elytron showing the thickened mar- 

 ginal nerve. 



Fig. 6. — The wing. 



Fig. 7. — The trimerous tarsus of the hind leg. 

 By inadvertence the two spurs on the femora, which 

 are noted in the text, have been omitted in fig. 1. 



Fig. 8. — The cleft termination of the male pygofer. 



Fig. 9. — A portion of the complex saw-apparatus of 

 the female. Two horny and serrated laminae have 

 been dissected out. Each lamina is strengthened by 

 two chitinous ridges, and towards the point a portion 

 is roughened, so as to act, probably, like a rasp. 



Fig. 10. — A portion of the saw more highly mag- 

 nified. The ova pass down the channel made by these 

 saws and their sheaths, into the groove excavated.
