ing (or rather including) the middle line, the anterior of these 

 elongate, the basal round, two on each side (occupying a large 

 portion of disc) ; surface rather closely punctate, the scarcely 

 concave explanate margins with much larger punctures. Scutel- 

 lum oval. Elytra ovate, subparallel at the middle, very convex 

 (gibbous in humeral region), of same width as prothorax at base, 

 humeri obtuse, widest at middle, strongly bispinose at apex, nar- 

 rowly bordered, and, with the epipleurae, closely irregularly fove- 

 ate-punctate, intervals smooth, vermiculate, sometimes showing a 

 longitudinal arrangement, foveae sometimes confluent, with smaller 

 bronze punctures within them ; of varied size, but larger and more 

 confluent towards sides. Abdomen nearly smooth, and with the 

 sternum brilliantly metallic, the last segment with a large central 

 depression, narrowed and curved at base, widened into a circular 

 excavation at apex; intercoxal process moderately wide, sides of 

 metasternum rugose-punctate, epimera with large round punc- 

 tures, prosternum punctured on sides, its process saddle-shaped, 

 not carinate, produced acutely forward, fitting into a widely tri- 

 angular cavity of the mesosternum behind ; legs long, tibiae pitted, 

 anterior tarsi enlarged, posterior tarsi with basal joint longer than 

 2 and 3 combined, claw- joint not as long as the rest combined, 

 clothed with reddish tomentum. Dimensions, 20-21 x 10J-1 lmm. 

 Hab. — North Queensland (F. P. Dodd), Upper Herbert River 

 (per C. French, F.L.S.). 



Two specimens, I believe Q, of this fine species under ex- 

 amination. A specimen sent also from the British Museum ; 

 there is one in the Macleay Museum. The curious abdominal 

 excavation, though unnoticed in other descriptions, occurs 

 also in P. Master si Pasc, and in P. cupricollis Macl., and 

 is possibly a sexual distinction, the obvious males having a 

 less regular depression. It occurs as an irregular depression 

 also in Cyphaleus ruyosus Gray, C. rerewsWaterh., C. fulgidipennis 

 Boisd., and C. insiynitus Pasc. P. ducalis is nearest to, though 

 very distinct from, P. Masteri Pasc, and P. aculeatus Westw.,(the 

 latter only known to me by description). From the former, it is 

 distinguished by the less closely punctate head, eyes larger and less
