In the structure of the anal excavation, closely allied to T. 

 subvittatus, but with the granules or tubercles much smaller, and 

 without the ridge on the undersurface of the anterior femora. 



Talaurinus scaijrosus Macl., loc. cit., p.235. 



(J. Large, elongate-ovate. Black, rather densely clothed with 

 muddy-grey scales, granules subnitid; setae minute, black. 



Head convex, ends of external rostral ridges continued back 

 along forehead. Rostrum moderately long, broad, excavate; 

 external ridges slightly confluent, junction with head marked by 

 a slight constriction; internal ridges obsolete, and median area 

 depressed. Scrobes deep, open posteriorly. Eyes subovate. 

 Prothorax (5*5 x 6*5 mm.) widest in front of middle, obtusely sub- 

 angulate, apex rounded above, ocular lobes well defined, collar- 

 constriction present; granules moderately large, discrete, rounded, 

 widely dispersed, leaving the centre and longitudinal areas near 

 sides free; granules obsolete on sides, except below lateral angle. 

 Elytra (14-5 x 9 mm.) ovate, apex strongly rounded, mucronate, 

 base subtruncate, humeral angle with a single tubercle; disc with 

 depressions obscured by clothing, interstices tuberculate, tubercles 

 unevenly distributed, more strongly developed and conical pos- 

 teriorly, sutural with a row of fine granules; second with six to 

 eight and a few small ones on declivity; third with seven to nine, 

 fourth with two or three, fifth with eight or nine, sixth with six 

 or seven, the last all conical tubercles; sides with rounded sub- 

 depressed granules. Below, each segment with a yellow macule 

 in centre; intermediate segments long; fifth with the anterior 

 portion depressed in centre, posterior portion strongly excavate 

 in middle, the division between the two portions marked with a 

 tubercle at either side. Anterior femora with a double ridge in 

 outer half. Dimensions : g. 2 2 -5 x 9 mm. 



Hab.— Queensland (Mitchell's Expedition). 



Perhaps a strongly tuberculate variety of T. verrucosus, but 

 with rather dense clothing between the tubercles. I am ignorant 

 of its exact habitat, the types, two males, in the Australian 

 Museum, being without exact locality-labels.
