408 REVISION OF THE GENUS SEIROTRANA, ETC., 



strongly bisinuate. The whole pronotum margined by a raised 

 shining border, thickest near anterior angles, thinnest at base. 

 Disc slightly raised in middle, depressed towards sides, glabrous, 

 but under a lens seen to be closely and finely punctate. At 

 posterior angles are small subfoveate depressions. Scutellum 

 large, forming an equilateral triangle with sides a little curved; 

 minutely punctate. Elytra 25 x 16 mm. Oval and very convex. 

 At base the same width as prothorax, soon widening in a regular 

 curve to the greatest width behind middle, near apex rather 

 suddenly and sinuately incurved, each elytron separately rounded 

 at apex. This subapical sinuation emphasised by the raised 

 shining border being discontinuous, the border from the shoulder 

 backwards ending abruptly at three-quarters the length, a second 

 more prominently raised border beginning inside this, and con- 

 tinued to apex. Disc very convex, with the greatest height in 

 front of middle, gradually curved to apex. Glabrous, closely, 

 finely, punctate, except sutural region and two smooth longitudinal 

 lines on each elytron. Abdomen and whole underside smooth and 

 very minutely punctate, the punctures becoming more evident 

 (but requiring a strong lens to be seen) towards apex. Legs : 

 femora and tibiae smooth, the latter straight, very little thickened 

 at apex, with small spine on inside.* Posterior tarsi with basal 

 joint not as long as the rest combined. Dimensions — 34-35 x 

 16 mm. 



Hab. — Kuranda, N.Q. (Messrs. C. Dodd and H. Brown). 



I have two specimens, the female from Mr. Dodd, the male 

 from Mr. P. Shaw, who received it from Mr. H. Brown. I have 

 seen one other specimen in the collection of Mr. C. French. It 

 is by far the largest species of the group, but I have little doubt 

 in placing it in this genus. The male has the prothorax slightly 

 more widely rounded, the fore tarsi more transverse, the elytra 

 more convex, and the abdomen thicker. 



* Pascoe in his tabulation of Cyphaleinse (Ann. Mag. Nat. Hist. April 

 1869, p. 288) gives ''basal joint of posterior tarsi as long as the rest together;" 

 but in C. childreni Westw., and O. victorienm Blackb., the proportions are 

 much as in the above species.
