tympanal coverings are ochraceons, sometimes with black sharlinKs ; the opercnla are wholly ochraceous, 

 and the fuscous markings to the tegmina much fainter in hue. 



Hal). — China : Chia Kou Ho, 1700 feet (Pratt — coll. Dist.) ; Shantung (coll. Dist.). Japan (coll. 

 Sign.) ; Yokohama (Brass. Mus.) ; Tokei (coll. Dist.). 



Varx. a. and b. are from China ; car. a. was sent home by Mr. Pratt from Chia Kou Ho, 

 and I am indebted to Mr. J. H. Leech for the possession of the same ; car. b. I received some 

 years ago from Shantung, in North China, and also a single Japanese specimen from the 

 collection of the late Mr. H. J. S. Pryer. Most of the specimens I have either examined or 

 received from Japan, exhibit the typical appearance here described. 



24. Pomponia obnubila. (Tab. VI., fig. 10, a, h.) 



Pomjionid ohnnhild, Distant, Ann. & Mag. Nat. Hist. ser. 6, vol. i. p. 296 (1888). 



Allied to P. maculaticollis, Motsch., but differing from that species by the darker and more obscure 

 hue of the body, the distinctly pale fuscous tegmina and wings, and by the length of the rostrum, which 

 considerably passes the posterior coxne and terminates on the overlapping opercula. 



The head is also much narrower than in P. macidaticollis, and the opercula are unicolorous and more 

 broadly and regularly convex posteriorly. 



Long. excl. tegm. 30 millim. Exp. tegm. 110 millim.

Genus PSITHYRISTEIA. 



Psithyristria, Stal, Ofv. Vet.-Ak. Forh. 1870, p. 712. 



This genus is quite unknown to the writer, and Stal's descriptions and figures of both 

 genus and species can therefore alone be reproduced.
