PSYLLIODKS BALYI. 31 



eyes. Carina narrow, strongly raised. Labrum obscure 

 piceous. Antennae slender , half the length of the body , 

 first and second joints of equal length and longer than 

 the third joint, the first three joints fulvous, the rest 

 black. Thorax scarcely twice as broad as long, the sides 

 straight , angulate in front of the middle , from there to 

 the apex obliquely shaped, the angle itself produced into 

 a small tooth , surface very closely and strongly punctu- 

 red , the interstices slightly rugose. Elytra strongly and 

 very regularly punctate-striate , the interstices towards the 

 sides and apex slightly convex. Posterior femora very 

 robust, greenish black, the other legs piceous; posterior 

 tarsi more or less distinctly fulvous, its apex finely dentate 

 at the edges. 



Ten specimens from Ajer Boesoek, Koetoer, Mesauw and 

 Soeroelangoen (Sumatra-Expedition). 



In its sculpturing of the upper surface , this species 

 agrees very nearly with P. Chapuisii Baly. It is however 

 much smaller and of a dark green colour, and the an- 

 tennae have only the first 3 joints fulvous. The present 

 insect is also much narrower and of more parallel shape. 



Nisotra gemella , Ericlis. 



The description of this author agrees so perfectly with the 

 numerous specimens from various localities of this collection , 

 that I should not be justified in considering the latter to repre- 

 sent another form , although the shape varies greatly in the 

 insects before me, and Erichson describes the type from 

 the Philippine Islands. All the insects before me are black 

 or piceous below, with the first 5 joints of the antennae, 

 the head, thorax and legs rufous. The elytra are gemi- 

 nate punctate-striate anteriorly , the punctuation varying 

 however in depth and intensity. The thorax has the usual 

 longitudinal groove at each side of the anterior margin.
