joint stout and dilated to near apex, second large, distorted, 

 and lop-sided, convex on lower-surface, irregularly concave 

 on upper, the following joints all short. Prothorax very- 

 little wider than long, sides rounded and distinctly wider at 

 apex than at base, with a transverse depression near base; 

 with dense and small, subrugose punctures, but becoming 

 rather sharply denned on sides. Elytra wider than base of 

 prothorax, sides gently dilated to beyond middle; with dense 

 and small but sharply-defined punctures, quite as distinct on 

 all parts of the black markings as elsewhere. Length 

 (<J, 9), 2-2Jmm. 



9 . Differs in having first joint of antennae smaller, 

 second joint much smaller and not distorted, and in the 

 front tarsi. 



Hab. — Northern Queensland (Blackburn's collection). 

 Type, I. 7569. 



The pattern of the elytral markings is somewhat as on 

 some of the smaller species, but the entirely black prothorax 

 and curious second joint of antennae arc very distinctive; the 

 second joint of the antennae of the female is much larger than 

 is usual on that sex, being almost as long as the third and 

 fourth combined, and considerably stouter. 



Laius flavonotatus, n. sp. 

 PI. xiii., figs. 11, 34, 35. 



<S . Black, with a vague bluish gloss; elytra with seven 

 flavous spots, second joint of antennae and part of abdomen 

 reddish-flavous. Clothed with short, blackish pubescence. 



Head gently convex, with a longitudinal impression in 

 middle, with an impression in front of each eye; with dense 

 and small punctures. Antennae short, first joint stout, with 

 an angular elevation in middle, second large and distorted, 

 convex on the lower-surface, irregularly concave on the upper, 

 and with irregular elevations, appearing different from almost 

 every point of view, the following joints all short. Prothorax 

 strongly transverse and evenly convex, sides strongly rounded ; 

 with small and very dense punctures. Elytra at base not 

 much wider than base of prothorax, but distinctly dilated to 

 near the apex; with dense, fairly large, and sharply-defined 

 punctures, smaller and sparser on the postmedian and apical 

 spots than elsewhere. Second joint of front tarsi rather large 

 and lop-sided. Length ( d , 9)> 2J-2J- mm. 



9 • Differs in having the head scarcely impressed along 

 middle, and not excavated in front of eyes, first joint of 

 antennae smaller and simple, second much smaller and simple 

 (it is, however, much larger and stouter than the third), and 

 in the front tarsi.
