second, fourth, and sixth intervals costate, the first two costae 

 terminated on the apical declivity and having a ragged sub- 

 crenulate edge, tending to become nodulose and interrupted 

 on apical half, the third costa with a zig-zag outline ; the sides 

 beyond this costa with four rows of deep, large foveate punc- 

 tures. Prosternum coarsely, epipleurae foveately, punctured ; 

 abdomen smooth, with short, sparse red hairs; anterior and 

 middle tibiae slightly curved. Dimensions — 13 x 6 mm. 



Rah. — Queensland: Duaringa (H. W. Brown). 



A very distinct species, easily separated from its allies, S. 

 catenulata, Bois., and S. proxima, Pasc, by its more convex 

 form, the widely upturned flanks of prothorax, with its acute, 

 produced front angles, and especially by the large elongate 

 punctures on elytra (somewhat as in Adelium plicigerum, 

 Pasc.) and the continuous costae. Two specimens were given 

 to Mr. W. du Boulay by Mr. Horace Brown, one of which 

 was generously given to me (female). Type in author's col- 

 lection. 



Seirotkana subcancellata, n. sp. 



Oblong oval ; bronzy-black, nitid above, nitid bronze be- 

 neath; oral organs, antennae, and tarsi reddish-brown, the last 

 clothed with golden pubescence. 



Head and pronotum vermiculate-punctate, the punctures 

 rounded and close, often confluent ; the nitid vermiculate in- 

 tervals less regular and longitudinal than in S. catenulata^ 

 Bois. ; epistoma rounded and arcuate in front, its suture nar- 

 rowly defined ; antennae reaching the base of prothorax, 

 gradually enlarged outwards, joint 3 shorter than 4-5 com- 

 bined, 4-10 subequal in length, obconic, 11 one and a half 

 times longer than 10, ovate. Pi^othorax, 3 x 4'5 mm., widest 

 in front of middle, base and apex of about equal width, 

 bisinuate at apex ; anterior angles slightly blunted and 

 advanced, their margins reflexed ; sides rounded anteriorly ; 

 posterior half gently converging to the undentate subrectan- 

 gular posterior angles, these overlapping the elytra ; foliate 

 margins moderately wide and concave in front, becoming 

 merged in the disc behind ; lateral border raised and crenulate, 

 the posterior crenulation forming a wide feeble sinuatfon ; 

 base slightly arcuate (advanced in the middle). Scutellum 

 transverse, oval, and punctate. Elytra slightly wider than 

 prothorax at base ; shoulders obtusely angled ; with ten rows 

 of large punctures, the first six rows at basal half with reticu- 

 late intervals, the last four rows on sides not reticulate, the 

 alternate intervals with straight catenulate costae ; prosternum, 

 episterna, and epipleurae very coarsely, the abdomen very 

 minutely, punctate. Dimensions — 13*5 x 5 mm.
