354' 



(4 J mm.), clothing entirely ashen, and elytral setae rather 

 more conspicuous. 



POLYPHRADES PLANIPENNIS, U. Sp. 



Black, parts of appendages very obscurely diluted with 

 red. Densely clothed with ashen scales, darker on the upper- 

 surface than on the under-surface; with dense setae. 



Rostrum short and wide, on an even plane with front of 

 head, with a narrow median line, inter-antennary space very 

 wide and obliquely dilated to eyes; apical plate triangular 

 and densely punctate. Scape stout; first joint of funicle 

 as long as second and third combined, third to seventh trans- 

 verse. Prothorax moderately transverse, sides strongly and 

 evenly rounded ; with small dense granules almost concealed 

 before abrasion. Elytra very wide, more than half of their 

 surface flat, base conjointly rather lightly arcuate, shoulders 

 strongly rounded, widest near base; with rows of large, 

 quadrate punctures, appearing much smaller, but in distinct 

 striae, before abrasion. Tibiae finely denticulate; claws 

 almost equal, separated for about half their length. Length, 

 6f-7 mm. 



Bab. — Northern Territory: Tennant Creek (J. F. Field). 

 Type, I. 5809. 



The very wide rostrum, not distinctly separated at base 

 from head and very wide between the scrobes, strongly and 

 evenly rounded sides of prothorax, and very wide elytra, will 

 in combination readily distinguish this species from the other 

 Northern Territory ones. Its general appearance is some- 

 what like that of latus, but the rostrum is very different. 

 Tumidulas, which also has the rostrum and front of head on 

 an .even plane, is a strikingly different species. The setae are 

 everywhere dense, on the prothorax they are mostly directed 

 towards the middle, on the elytra, in conjunction with the 

 dense clothing on the interstices, they give the surface a 

 striped appearance. The discal portion of the elytra is 

 unusually wide and flat. 



POLYPHRADES DURIUSCULUS, 11. Sp. 



Black, tarsi obscurely diluted with red. Densely clothed 

 with muddy-brown scales, feebly variegated in places, and 

 mixed with numerous stout setae. 



Eyes almost circular and rather prominent. Rostrum 

 rather short and wide, feebly depressed along middle, inter- 

 antennary space conspicuously narrowed to middle, where 

 the width is about equal to that of an eye; apical triangle 

 distinctly elevated and punctate. Scape rather short, lightly 

 curved ; basal joint -of funicle not very long, slightly longer
