^SERNIA AUSTRAUCA. 301 



The species of yEsernia described here, and of which more 

 thau 30 specimens are before me which have beea kindly 

 sent to me for examination by Mr. Neervoort van de Poll , 

 seems to be intermediate between A. Whitei Baly and A. 

 splendens Guer. It differs from the first in the shorter an- 

 tennae , the smaller greenish spot at the vertex of the head 

 and in the pattern of the elytra , which , instead of having 

 a narrow transverse fulvous band as in A. Whitei have 

 their entire apices and part of the sides flavous; this co- 

 lour forms a broad lateral band, extending upwards to 

 the first third of the elytra , the anterior edge of this band 

 is straight and acutely separated from the metallic portion 

 which extends posteriorly along the suture in a broadly 

 rounded angle, causing the inner margin of the flavous 

 band to assume a concave shape; the two small lateral 

 greenish spots of the thorax are as often absent as pre- 

 sent, and the femora 'are either entirely metallic or with 

 a fulvous upper or lower margin. The colour of the thorax 

 and the shape of the elytral flavous band separates A. au- 

 stralica from A. splendens. 



Of the present genus , no species was previously known 

 from Australia. I give here the description of another ap- 

 parently new species contained in my collection , and of 

 which a variety has also been received by Mr. van de Poll 

 from Australia.
