154 NOTES ON AUSTRALIAN COLEOPTERA, 



Head flat, punctate, epistoma truncate, labrum prominent, 

 antenna? short, joints moniliform, the last three transverse. 

 Prothorax 2x5 mm , length measured in middle, width at base; 

 apex semicircular, embracing nearly half the head, all angles 

 rounded, the posterior rather narrow ; sides converging and 

 nearly straight, from base to apex; explanate margins wide, sub- 

 horizontal, disc convex, roughly and rather closely granulose, 

 showing smooth spaces along middle line; base bisinuate. Elytra 

 slightly wider than prothorax at base, very convex, widest a 

 little behind middle, without explanate margins, lateral border 

 not seen from above (through convexity), each with three fine, 

 linear, and slightly undulate costa? and a rudimentary fourth 

 costa on side; the first and third extending from base to apical 

 declivity, the second continuous for about two thirds of length, 

 an elongate nodule forming its continuation; the fourth costi- 

 form only for a short distance, thence represented by a few 

 small, distant nodules; a few scattered nodules on apical region; 

 suture quite flat, the whole covered with a pale, squamose meal, 

 with short, upright hairs; underside and legs with close, short, 

 hairy clothing ; anterior tibia? coarsely, intermediate finely 

 serrated on outside. Dimensions : 9x6 mm. 



#a6.-Cambo-Cambo, Northern N.S.W. (S. W. Jackson). 



A single specimen, given me by the late Mr. K. Helms, is 

 nearest *S'. Icevicostatus Macl., in general facies, but the costa; 

 are more continuous; it is without the intermediate rows of 

 nodules, the pronotum is more roughly granulose, inter multa 

 alia. (The pronotum of 6'. laivicostatus Mac)., is more rugose 

 than granulose, showing small granules only near base. The 

 presumed types in the Macleay Museum are larger than as 

 given in the description, and they measure 11-12 x 7-7£mm.). 

 The form of the elytra, without any sign of flange, and the hairy 

 clothing, give it a likeness to Trichosarayus jrilosellus Blackb., 

 but the marginal prothorax and wider form proclaim it a true 

 Sarayus. 



Type in Coll. Carter.
