PLATYNEMA OLLIFFI. 29 



NOTE V. 



DESCRIPTION OE A NEW SPECIES 

 OF THE NITIDULID GENUS PLATYNEMA, RITS. 

 (ORTHOGRAMMA , MURRAY') nec GUENÉE). 



C. RITSEMA Cz. 



Of this species I have seen three specimens, captured 

 in the Andaman Islands, and of these Mr. A, Sidney 

 Ollifif has been good enough to let the Leyden Museum 

 have two; I therefore propose to call the species 

 Platynema Ollijffi. 



Length 4,5 mm. — Elongate, subparallel, gradually 

 widening a little towards the middle of the abdomen, de- 

 pressed , shining , dark piceous with tinges of purple , 

 green and blue, which are more conspicuous on the tho- 

 rax than on the head , elytra and abdomen ; the part of 

 the head before the eyes, as well as the two basal joints 

 of the antennae rufous; the extreme lateral margins of 

 the thorax narrowly testaceous; the elytra testaceous , pass- 

 ing into dark brown at the sides and into piceous at 

 about two thirds of their length ; the apical margin of 

 the abdominal segments narrowly testaceous ; the legs dark 

 brown , brighter at the knees ; the tarsi pale testaceous. 



1) This generic name, which dates from the year 1864, cannot be retained, 

 as Guenee had already used it in 1852 in the Lepidopterous family Noc- 

 tuidae. I therefore propose to substitute Murray's name by Platynema (from 

 7r?iXTVi; , flat, and vsj//a, a thread).
