BRITISH ORTHOPTERA. 175 



and eggs as well as the imago. Easily distinguished by its 

 large size and long unspotted green elytra ; it is usually found 

 on trees and bushes, and is not uncommon in many localities 

 during August and September. Omnivorous. Collectors should 

 be careful not to allow this species to bite them (as it will 

 certainly do if they put their fingers too near) ; it will, however, 

 be an interesting experiment for any one seeking information. 

 This insect is said to be excellent when boiled in water for half- 

 an-hour (having thrown away the head, wings, and legs), then 

 sprinkled with salt and pepper and fried, adding a little butter.

1. T. cinerens, L., 1789. = griseo-ajJtera, DeGeer; aptera, 

 Charp. ; dypeata, Panz. — Eesembles Odontiira in having extremely 

 short elytra, but may be distinguished from it by the very long 

 thorax ; it should be looked for among herbage during September. 

 The males are much rarer than the females. Fig. 6.

1. D. griseus, Fab., 1793. = denticulata , Panz. ; falcata, 

 Zett. ; intermedius, Serv., var. ; krynickii, Fisch., var. — Very 

 local and rare, preferring chalky maritime districts ; it occurs 

 from July to September. 



2. D. hrevipennis, Charp. — Found amongst herbage, &c., in 

 July and August. Local, but not uncommon. Fig. 7. 



8. D. brachypterus, L., 1745. = kirbii. Dale. — In this species 

 the ovipositor is more than half the length of the abnomen, 

 whereas in D. hrevipennis it is less. Occurs on herbage from 

 July to September. 



4. D. verrucivorus, L., 1761. = hinglei, Curt. — This insect 

 is figured in Curtis's 'British Entomology,' ii. 82. Bare and 

 very local; it occurs during August and September, usually 

 amongst grass near the sea-coast. The Swedish peasants are 

 said to make this insect bite the warts on their hands in order 

 to cure them. D. verrucivorus can be distinguished from 

 Phasgonura by its more robust form, spotted elytra, and the curved 

 ovipositor of the female (which in Phasgonura is nearly straight).
