GNAPHALORYX PERFORATUS. 41 



terior tibiae are armed in the middle on the outside with 

 a spine which is very distinct on the middle legs , but almost 

 not noticeable on the hind pair. 



Hab. Sumatra. — A single male specimen, kindly pre- 

 sented in exchange to the Leyden Museum by Mr. J. R. 

 H, Neervoort van de Poll. 



This is the third horned species described in the genus 

 Gnaphaloryx. The two others are : miles v. Voll. from Hal- 

 maheira and Gebeh, and tricuspis Rits. from Sumatra. 



Cetoniidae, 



Argyripa subfasciata , n. sp. 9* 

 (Plate 3, fig. 2). 



Length 25 mm. , width of the shoulders of the elytra 

 12,5 ram. — Above partially covered with a yellow crust, 

 partially velvety. Beneath brilliant metallic green shading 

 into blue, with a golden lustre, the mesosternal appendage , 

 a line along the middle of the mesosternum , a semicircular 

 spot at the middle of the base of the 2nd — 5th abdominal 

 segment, and numerous points on the thighs and on the 

 sides of the breast and abdomen black ; the tibiae and tarsi 

 are also black. 



The clypeus pale golden green with a beautiful metallic 

 hue , the raised margins black ; the remaining part of the 

 uppersurface of the head covered with a yellow crust. — 

 The uppersurface of the thorax covered with a similar yellow 

 crust, with the exception of the central region where a 

 large velvety black spot occurs , which has (at least in the 

 single specimen before me) the shape of the head (with 

 exerted antennae) and thorax of a large clavicorn beetle, 

 viz. a Necrophorus '). Moreover a few black points are 

 present on the anterior half near to the lateral margins. — 



1) Perhaps the shape of this spot will prove to be variable, as the presumed 

 antennae are formed by a conglomeration of black points.
