1120 COLEOPTEEA 



is obscure -yellowish, but there are numerous patches of dark colour 

 arranged in a serial manner ; these patches are of irregular outline, 

 and those in each series tend to be connected with one another; seen 

 in a certain light the elytra assume, in consequence of these patches, 

 a brilliant appearance. The sides of the breast are rather closely 

 punctate. I have five individuals before me, but can detect no 

 sexual distinctions. 



Greymouth : Helms. Henry Edwards, Esq., New Zealand. 



Group EUCNEMID^E. 



Agalba. 



Nov. gen. 



Allied to Talerax, but exhibiting some important structural 

 differences. 



Antenna rather less approximate, thick, sometimes serrate ; their 

 cavities large, oblique, quite visible from above, and extending in- 

 wards in line with the front and inner margin of the eyes ; the head 

 itself more or less evidently carinate along the middle ; the forehead 

 is angularly dilated in front ; the labrum I cannot see ; the mandibles 

 are much exposed. Prosternum with simple, oblique sutures, with- 

 out any frontal transverse groove; it is sinuous in front, and is so 

 shortened that the flanks project forwards a good deal beyond its 

 central portion ; the small saltatorial mucro is deflected, so as to 

 be on a lower plane than the sternal process. Mesosternal cavity 

 with slightly- thickened borders, not, however, raised, and reaching 

 the intercoxal suture. Coxal lamina almost quite straight behind, 

 the fine frontal suture continued obliquely and curvedly forwards, 

 so that, at the side, the lamina is about twice as long as it is near 

 the trochanter. Eyes smaller than in Talerax, and not so pro- 

 minent, 



1988. A. ruficorne, n.s. Convex, subcylindric, not narrow ; 

 sparingly clothed with very fine, short, yellowish hairs ; glossy, 

 dark rich brown ; the apex and hind angles of thorax, the scutellum, 

 and base of elytra rufescent ; legs f ulvescent ; antennae red. 



Head rather broad, with a slender frontal carina, moderately 

 finely and closely punctured. Antenna with yellow pubescence, 

 thick, not serrate ; basal joint curvate, nearly as long as the next 

 three ; second not abbreviated, third a little shorter than it ; 4-10 

 almost transversely quadrate. Thorax broader than long, convex, 

 but much depressed at the base, apex subtruncate ; front angles 

 deflected, the posterior rather short, not acute, directed almost 

 straight backwards; its surface finely and distantly punctured. 

 Scutellum smooth. Elytra slightly narrowed behind, with raised 

 shoulders; they bear numerous series of rather fine punctures, 

 which, however, do not form striae. 



$ . Length, 2 lines; breadth, nearly f line.
