Chalcotaenia castanea, n. sp. 

 PL ix., fig. 1. 



Widely navicular. Above nitid-castaneous, head and 

 pronotum with iridescent, coppery, and violet reflections, 

 apex of elytra with faint greenish reflections; head, depres- 

 sions on pronotum and elytra filled with yellow pubescence, 

 antennae reddish-coppery; underside and legs coppery, with 

 white short pubescence. 



Read, forehead concave, concavity broadened by rugose 

 ridge, sulcate in middle, a small shining nodule on each side 

 of sulcus, finely punctate at base. Pronotum trapeziform, 

 feebly rounded at sides, anterior angles rounded, posterior 

 acute, longitudinally sulcate in middle, and two wide longi- 

 tudinal depressions, rest of surface irregularly rugose-punc- 

 tate with smooth spaces near middle. Scutellum fiery- 

 coppery. Elytra of male of same width as of female, 

 considerably wider than prothorax at base, sides sinuately 

 compressed behind shoulder, strongly serrated towards apex, 

 with five wide and little-raised costae (including the sutural), 

 the first, second, and fifth continuous throughout, the third 

 starting from middle and joining the second towards apex, 

 the fourth abbreviated, extending from humeral callus to 

 halfway; a wide irregular depression extending from base to 

 the starting-point of the third oosta and expanding at base, 

 the depression between the fourth and fifth costae widening 

 at the apical third, the raised parts sparsely punctate. 

 Mttastei\num coarsely rugose-punctate, prosternum and meso- 

 sternum much less so; abdomen with longitudinal nitid space 

 sparsely punctate towards size, besides the nitid central costa, 

 last segment of male with small irregular excision, of female 

 apex produced into two blunt lobes. Dim., $ , 22x8 mm.; 

 9, 29 x 10 mm. 



Hob. — Western Australia: Cue (H. W. Brown). 



Another of Mr. Brown's captures in this prolific region, 

 and strikingly different from all described species in colour 

 alone. The sculpture of the upper-surface is more irregular 

 than in other species of the genus, being without well-defined 

 pubescent spots, the usual position of these being merely 

 indicated by enlargements of the longitudinal depressions, 

 while the costae are only clearly carinate towards the apex. 

 The apical process of the female is unusual. Type in the 

 author's collection. 



PSEUDOTAENIA SPILOTA, 11. Sp.
