3. Platy pleura yayeyamana n- sp. 



Allied also to P. kacmpferi F., but differs from it as follows : — 

 Pronotal angles much produced and nearly at right angles, central spots to 

 the mesonotum connected with each other and nearly of a rectangular form, from 

 the middle of which posteriorly sending a black stripe; opercula fuscous at the 

 extreme margin, and a spot near the base, ochraceous ; subapical fasciate fuscous 

 spot to the tegmina nearly parallel to the double row of the apical spots, those of 

 the second and third longitudinal veins connected with each other, and those of 

 the third, fourth and fifth much smaller, marginal membrane being much broader ; 

 hyaline marginal membrane to the wings much broader. 



Leegth — excl. tegm. 20 mm.; exp. tegm. 68 n^m.; breadth of the pronotal 



angles 13 mm. 

 Hab. — Yayeyama (Ishigakijima) ; 4 % specimen collected by Messrs. K. 



Kuroiwa and T. Iwasaki. 

 Nom. Jap. — Yayeyaina-Ni-ni. 



2. Gen. Pycna Am. Serv. 



4. Pycna miyakona "• sp. 



Allied to P. repanda " F., from which it differs in the following points : — 



1. Operacula pale ochraceous, on its inner margin narrowly fuscous, at the 

 apex a little more rounded. 



2. A large subapical fasciate fuscous spot to the tegmina independent, inner 

 row of the apical spots triangular, becoming smaller towards the hind margin, 

 each being accompanied by a double spot on each apex of the longitudinal vein ; 

 inner spot at the apex of the 7th longitudinal vein roundish. 



3. Wings velvety black, apex of each apical area narrowly and outer margin 

 broadly hyaline, apex of the anal' area being white and opaque. 



Length — excl. tegm. 23-26 mm.; exp. tegm. 70-80 mm.; breadth between 



the pronotal angles 13-15 mm. 

 Hab. — Miyakojima, Riukiu, 8 (5 J, 3 %) specimens collected by Mr. K. 



Kuroiwa. 



') Pyona rapanda K. was reported from Japan and China, Imt according to my present know- 

 ledge it is known only from E, India and Burma. The species identified as P. rej>anda were mostly 

 Platypteura kaempferi F. or its varieties.
