a remarkable extent in shape, and in the femora. Mr. Pascoe 

 described the three intermediate segments of the abdomen as 

 being subequal, but, in this, he was certainly wrong, the second 

 segment being, in reality, as long as the third and fourth com- 

 bined, as may be distinctly seen in S. iatissimus; but, in S. 

 elevatus, it is excavated along the middle, leaving the posterior 

 half of the same shape and appearance as the two following ones, 

 so that, on a cursory examination, the three segments really do 

 appear to be equal in length. 



In Australia, the genus is confined to Queensland, but several 

 species occur in New Guinea and the Malay Archipelago. 



Femora dentate, elytra without epipleural fold elevatus. 



Femora edentate, elytra with epipleural fold Iatissimus. 



Salcus elevatus Pasc; Mast. Cat., Sp.No.5495. 



Upper surface with moderately long greyish scales, not very 

 densely distributed, and giving the surface a very dingy appear- 

 ance. 



Elliptic, strongly convex. Bead sparsely punctate. Rostrum 

 very feebly incurved to middle : feebly (subseriately behind 

 antennae) punctate, and without scales, except at extreme base 

 and sides. Prothorax not twice as long as wide, with scattered 

 punctures, each of which contains, and is entirely concealed by, 

 a scale. Elytra about once and one-third as long as wide ; 

 seriate-punctate, punctures never very close together, small about 

 suture, but becoming very large towards sides. Basal segment 

 of abdomen coarsely and irregularly punctate; second oblique, 

 across its middle deeply excavated so that (except at sides) it 

 appears to be divided into two parts. Femora distinctly grooved, 

 dentate, teeth of front pair small, of the four hind ones very 

 small. Length, 5 J-8 mm. 



Hah. — Queensland : Port Bowen, Cairns, Barron Falls, Bar- 

 nard Island. 



The elytra are strongly convex and without trace of an epi- 

 pleural fold. 



A specimen from Cooktown is almost entirely abraded on the 

 upper surface. It appears to be rather wider than the specimens
