with small punctures scattered about, and a few moderately 

 large ones on sides. Elytra rather elongate, scarcely wider 

 than base of prothorax ; with fairly dense punctures, not 

 arranged in regular rows, and of almost even size throughout. 

 Flanks of 'prosfernum impunctate. Front femora strongly 

 dentate. Length, 5 mm.

The elytral punctures are not arranged in regular rows,, 

 but a few feeble longitudinal elevations (about four on each 

 elytron) appear to divide them off into certain feebly-defined 

 areas : on the apical slope, however, the striation is sharply 

 pronounced, and the punctures in each stria are distinct. The 

 middle tibiae appear to be very feebly notched near the outer 

 apex, but the notch is much less distinct than on any species of 

 llhyijarida ; the antennae, front legs, and elytral striation are 

 also different to those of any species of that genus. The tip 

 of the antennae is but lightly infuscated. The type is prob- 

 ably a male, as the fourth segment of its abdomen is decidedly^ 

 longer than the third, the fifth is widely incurved at the apex, 

 but not distinctly impressed; the basal joint of the four front 

 tarsi is moderately large.

d . Reddish-brown with a metallic-green gloss, appen- 

 dages (tips of antennae and claws excepted) paler. 



Read depressed and with rather numerous distinct punc- 

 tures between eyes, much smaller and sparser elsewhere, with 

 a feeble median line. Antennae elongate, second joint almost 

 as long as third, the latter scarcely half the length of fourth, 

 fourth and fifth subequal in length and wider than the follow- 

 ing ones. Frotliorax with rather large irregularly distributed 

 punctures, nowhere very dense, but larger on sides than on 

 disc. Eh/fixi with dense and rather large punctures, becoming 

 smaller and in regular striae posteriorly, and frequently con- 

 fluent behind shoulders. Flanks of prostermim with punctures 

 on basal half only. Fourth segment of ahdomen with a wide, 

 shallow median impression and a smaller one on each side; 

 fifth about half the length of fourth and irregularly trans- 

 versely impressed. Front femora acutely dentate; hind tibiae 

 with apical two-fifths dilated on lower-surface; basal joint of 

 four front tarsi strongly inflated. Length, 6^-7^ mm. 



9 . Differs in having evenly convex abdomen, with fifth 

 segment scarcely shorter than fourth, simple hind tibiae, and 

 basal joint of four front tarsi much smaller.
