536 Mr. C. O. Waterliouse's Notes on 



Heterocerus Australasice, sp. nov. 



Oblongus, sub-opacus, testaceus, pubescens ; capite 

 fusco, elytris singulis maculis tribus infuscatis ad suturam 

 connexis ornatis. 



Long. 3^ mill. ; lat. 1^ mill. 



Head blackish-brown. Thorax transverse, twice as 

 broad as long, convex, straight in front, much rounded 

 at the sides, rounded behind ; testaceous, with the disk 

 slightly tinged with brown. Elytra as broad as the thorax 

 and three times as long, thickly and very delicately punc- 

 tulate ; testaceous, Avith the posterior half of the suture 

 and three spots on each elytron pale fuscous ; the basal 

 spot commences on the shoulder, extends down the middle 

 of the elytron, and then turns to join the suture ; the 

 second spot is near the margin, and extends to join the 

 basal spot just before it joins the sutm*e ; the third spot 

 is like the lette" z (I'eversed on the left elytron), placed 

 obliquely, and occupying the apical area. 



This species most nearly resembles H. sericans, and is 

 very like it in form. Besides the difference of size and 

 markings above described, it has the elytra more finely 

 punctured, and they are distinctly narrowed immediately 

 below the shoulders.

The characters Avhich separate this genus from tlie 

 American genus Deltochilum are slight, but I think suffi- 

 cient to justify its adoption as a distinct genus. 



The metathoracic episterna are elongate and narrow. 

 Anterior tarsi short, stout. Pygidium small and perpen- 

 dicular. Posterior tibiae straight, except at the extreme 

 base, crenulate on the inner side. Thorax produced 

 behind in the middle in a point over the suture of the 

 elytra. Basal joint of the posterior tarsi very shoi't, shorter 

 than the second.
