BY E. P. VAN DUZEE, BUFFALO, N, Y. 



Gnathodiis iinpidiis, n. sp. 



Green, or yellowish green in the dried specimen ; scutellum and all 

 beneath quite strongly tinged with yellow. Corium whitish hyaline, ner- 

 vures green and strong, especially in the male. Wings white, iridescent, 

 nervures pale. Eyes blackish. Antennae and legs soiled yellow tinged 

 with green, especially on the posterior tibiae. Otherwise immaculate. 



Genital characters. Male : Valve short, hind edge but feebly 

 arcuated. Plates broad and short, outer edge rounded, with a few short, 

 stout, white spines ; tips abrupt, narrow whitish, about one-half as long 

 as the disc of the plates, placed nearly their own width from the sutural 

 edge and approximated at apex. Pygofers moderately surpassing the 

 plates, their leaf-like apices commencing at the extreme tip of the plates, 

 where they are quite widely separated, and approaching posteriorly. 

 Female : Last ventral segment long, slightly narrowed posteriorly and 

 truncated at apex. Pygofers narrow, scarcely swollen at the middle, 

 equalling in length the stout oviduct, disc armed with stout spines nearly 

 to the base. Length 3^ mm. 



New Jersey. Described from a single pair received from Prof J. B. 

 Smith, and labelled " New Brunswick, July 20." 



Gnathodus abdominalis, n. sp. 



Smaller than the preceding. Green, disc of the tergum brown, venter 

 brownish green. Pronotum with three nearly obsolete longitudinal 

 fulvous bands, continued over the basal field of the scutellum. where 

 the lateral ones appear as fulvous-brown spots within the basal 

 angles. Elytra whitish tinged with smoky on their apex, nervures con- 

 colorous but distinct. Wings slightly enfumed, nervures brown. Tibial 

 spines pale ; claws brown. In faded examples the colour becomes whitish 

 or yellowish green with the fulvous bands obsolete, or nearly so. 



Genital characters. Male : Valve large, as long as the two apical 

 ventral segments taken together ; apex angled, subacute. Plates but little 

 surpassing the valve, narrow and pointed, fringed with stout spines. 

 Pygofers long, their expanded tips slightly separated at base but approxi- 

 mated beyond. Length, 3 mm. 



New Jersey. Described from two male examples received from Prof. 

 Smith,, and taken at New Brunswick, July 20th, and Jamesburgh, July
