(4 x 5 mm.) not greatly widened, but obtusely subangulate on sides, 

 postorbital sinuosity moderately well developed, lobes feeble; an 

 irregular, feeble collar-impression present ; median line not 

 impressed, but without granules ; with small hemispherical 

 granules, not contiguous and slightly irregular in size ; sides 

 granulate. Elytra (11x7 mm.) subovate, apex moderately 

 abruptly rounded, base arcuate; humeral angles tuberculiform, 

 projecting laterally; sculpture rough and confused, with small 

 rounded granules hardly in striae, interstices not raised but with 

 rather strong nitid tubercles, sutural with three or four small 

 granules at base, second with three distant tubercles in middle, 

 and three more conical on declivity, extending to apex; third 

 with five smaller rounded ones extending from base to middle, 

 and two more posteriorly; fourth with two near middle, fifth 

 with three spaced out ones near shoulder, and four or five more 

 conical and more closely placed posteriorly ; sixth with four 

 conical distantly placed tubercles, seventh with six smaller ones; 

 sides transversely rugose, not granulate. Beneath, with a few 

 scattered setae; intermediates long, fifth rather deeply subquad- 

 rately excavate, edges ending abruptly in tuberculiform pro- 

 jections, middle of segment thickly clothed with black, hirsute, 

 setse. Apical tergite rugosely punctured at apex. Legs rather 

 long and slender; anterior femora with a prominent ridge beneath 

 in outer half. 



Q. More robustly ovate, with elytral tubercles rather larger, 

 and about six in all on third interstice, larger and more conical; 

 beneath, convex; fifth with a feeble impression at extreme apex. 

 Dimensions : (J. 17 x 7; 9. 18 x 8 mm. 



Hab. — North Queensland (received from F. P. Dodd, per T. G. 

 Sloane, collected in the Atherton District). 



Mr. Dodd has forwarded one male and four females belonging 

 to this species; the females show a good deal of variation both in 

 size, and in the number and position of the elytral tubercles. 



It appears to be most closely allied to the common New South 

 Wales species, T. bucephalus; but the clothing and the sculpture 

 of the anal excavation of the male prohibit my regarding it as a 

 variety. One of the females before me measures 21x9 mm.
