Similar in size to and densely pubescent like T. cnchsoiri, but without a 

 small red spot on each side of the apex, and hence the pale markings of the elytra 

 in two series only (constant on twenty-eight specimens), the dark median fascia 

 -considerably wider, and not zigzagged, and the j^unctures somewhat stronger. 

 Of the pale fascia^ the first occupies the basal two-fifths of the elytra, except for 

 a large subquadrate patch adjacent to the scutellum (the spot is sometimes rather 

 feebly infuscated), the second is at the apical third, the part on each elytron is 

 convex on its anterior margin, concave on its posterior and narrowed to the 

 suture ; the under surface and legs are somewhat paler than the head and 

 prothorax. Two of the specimens from Derby have the dark parts black; on a 

 few of the Queensland ones they are almost black. 



THALLIS MELANCHOLIC A y.p. n.-v. 



Black; legs, antenna?, and palpi more or less reddish; abdomen obscurely 

 diluted with red. Rather densely clothed with sub-erect, rusty pubescence. 



Head with dense and fairly large punctures. Antenuje with fourth joint 

 about two-thirds the length of third, and slightly longer than fifth. Prothorax 

 about once and two-thirds as wide as long, apex truncated in middle, and notched 

 near each side, sides slightly and irregularly serrated, a rather deep line near 

 each side ; punctures slightly larger than on head, becoming smaller and denser 

 in front. Elytra parallel-sided to near apex, with regular rows of fairly large 

 punctures, becoming smaller posteriorly; interstices with numerous distinct but 

 rather small punctures. Intercoxal process of prosternum moderately wide, 

 obtusely pointed. Abdomen with coxal lines traceable to lieyond middle of basal 

 .segment. Inner edge of front tibue minutely serrated. Length, 7-9 mm.

Although the derm of the majority of the specimens is of a shining black, it 

 appears, to the naked eye, more or less dark rusty brown, owing to the pubescence ; 

 some of the specimens, however, are really rusty brown with the abdomen paler,
