248 Mr. Arthur M. Lea's Revision of the 



The pubescence is much like that of heltnsi, but is 

 distinctly shorter and not of the almost snowy whiteness 

 of that species. In appearance it is close to the following 

 species, but is slightly larger and with more distinct 

 punctures on both prothorax and elytra ; in shape it is 

 intermediate between that species and abundans. 



Dasytes coeticarioides, n. sp. 



Black ; the elytra sometimes not quite so dark. Densely clothed 

 with short, whitish pubescence. 



Head minutely punctate ; gently convex. Antennae just passing 

 scutellum. Prothorax twice as wide as long, sides strongly rounded, 

 gently convex throughout ; densely and minutely punctate. Elytra 

 rubovate, closely applied to prothorax, suture narrowly raised on 

 posterior two-thirds ; densely and minute punctate, at base punctures 

 rather larger than on prothorax. 



Length I5-IJ mm. 



Hob. W. Australia : Rottnest Island, Darling Ranges, 

 Swan River; N. S. Wales: Sydney {A. M. Lea). 



Of the short robust form of helmsi, but much smaller, 

 pubescence sparser and darker, etc. The elytra are often 

 quite as dark as the rest of the body, but frequently are of 

 a very dark brown only. Except as to its colour it is 

 not unlike many species of Corticai^ia. I cannot find any 

 distinguishing features between the eastern and western 

 forms. 



Dasytes amplicollis, n. sp. 



Black, the upper surface with a slight greenish gloss. Densely 

 clothed with short whitish pubescence. 



Head indistinctly punctate, gently convex. Antennae short, not 

 extending to scutellum. Prothorax scarcely twice as wide as long ; 

 strongly convex ; sides strongly rounded ; with minute punctures in 

 middle, becoming clearly defined and comparatively large on sides. 

 Elytra rather closely applied to prothorax, but nowhere wider than 

 the greatest width of that segment ; with dense and rather minute 

 punctures; suture scarcely visibly raised posteriorly. 



Length 1 j mm. 



Hah. W. Australia : Swan River {A. 31. lea). 



Of the size and somewhat after the build of the pre- 

 ceding species, but the prothorax considerably larger in 

 proportion to the elytra and with larger punctures, 

 especially at the sides.
