Eyes large, widely and rather shallowly notched in front. 

 Antennae long and thin, eleventh joint slightly shorter than 

 tenth and conspicuously semidouble. Apical joint of maxillary 

 palpi long, rather thin, and subreniform. Prothorax much 

 longer than wide, sides rather suddenly inflated near apex, 

 base narrowly upturned; with crowded and sharply-defined 

 but rather small punctures. Elytra much wider than pro- 

 thorax; each with four conspicuous discal costae, of which 

 the third is shorter than the others; densely and finely 

 granulate-punctate or shagreened. First segment of abdomen 

 small, the fifth strongly bisinuate at apex. Legs long and 

 thin. Length ( d , 9), 11-19 mm. 



9 . Differs in being rather more robust, legs and 

 antennae somewhat shorter, apical joint of palpi somewhat 

 stouter, and apical segment of abdomen not bisinuate. 



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

 Mackay (National Museum), Port Alma (H. J. Carter), 

 Brisbane (H. Hacker's No. 281, and Dr. A. J. Turner). 

 Type, I. 6748. 



Structurally fairly close to nigronotata, but the average 

 size considerably larger (it is the largest known Australian 

 species of the genus) and with very conspicuous markings. 

 The infuscated parts are the space between and in front of 

 the eyes, the labrum, tips of mandibles, parts of palpi, apical 

 portion of each antennal joint, three conspicuous lines on 

 pronotum (occupying most of its surface), most of elytra, 

 parts of abdomen, knees, and parts of tibiae and tarsi; the 

 elytra have a striped appearance owing to the elevated lines 

 being paler (sometimes very conspicuously so) than the 

 adjacent parts; they also have two (or three) sutural spaces 

 that are paler than the other parts, and are bounded in front 

 and behind by conspicuously dark parts (the surface there hav- 

 ing a curiously interrupted appearance), one of the pale spaces 

 is median, subquadrate, and terminated by the first discal 

 elevation ; there is a somewhat similar space between it and 

 the apex, and the occasional third spot is half-way between 

 the median one and the base; but on some specimens the 

 subsutural markings are ill-defined ; on an occasional specimen 

 the infuscation extends to the metasternum. The surface of 

 the pronotum is gently undulating rather than with distinct 

 impressions ; in the male at its narrowest it is only about 

 half its length. 



COPIDITA ILLOTA, n. Sp. 



9 . Of a dingy pale flavous : head between eyes, 

 antennae, palpi, pronotum, a lateral vitta on each elytron, 

 knees, and parts of tibiae and of tarsi more or less infuscated. 

 Densely clothed with short, pale, depressed pubescence.
