206 REVISION" OF PTEROHEL.EUS (conlcl.) AND SARAClfS, ETC., 



Head wide, convex on forehead, epistoina depressed, 

 rounded in front, and limited behind by a transverse suture, 

 immersed in the prothorax to the eyes, the latter small. Sur- 

 face of head and prothorax finely, closely punctured. Pro- 

 thorax (1-5 X 3-5 mm.), subtruncate at apex, with anterior 

 angles subrectangular and strongly produced forward, sides 

 a little arcuate anteriorly, then almost parallel to base ; pos- 

 terior angles obtuse, base truncate, with a narrow horizontal 

 margin at sides, base and apex with evident but very narrow 

 border, without central channel. Scutellum round, with a 

 central puncture. Elytra closely fitting prothorax, and of 

 same width at base ; sides subparallel, apex bluntly rounded, 

 striate-punctate, with nine strise on each elytron (three of 

 these on the sides), striae filled by close, rather large punc- 

 tures, intervals a little convex, especially near sides, and 

 apparently impunctate. Under surface finely punctate, 

 prosternum convex, legs short, intermediate and posterior 

 tibiae very thin, fore tibiae a little expanded at apex, all tibiae 

 minutely spined at apex, posterior intercoxal process trian- 

 gular. JJi/iieiisioi/i< : 4-5 x 2-8 mm. 



II ah. — Blue Mountains, New South Wales; and Vic- 

 toria (?). 



Several specimens were taken by the author and Dr. E. W. 

 Ferguson at Mount Wilson, under bark of rotting Eucalyptus 

 logs. I have since taken individual specimens at Medlow 

 (Blue Mountains), and one specimen has been sent to me by 

 Mr. C. French (without locality-label), probably from Vic- 

 toria. It is readily distinguished from Arf/ioftiis by its broad, 

 depressed form, and apparently undenticulate tibice. The 

 mici'oscope, however, sliows minute .spines. One specimen is 

 undoubtedly male, but I cannot detect any decided sexual 

 characters in the structure. 



I am indebted to Mr. F. A. Taylor, of the Technological 

 Museum, Sydney, for the micro-])hotographs reproduced in 

 Plate viii.
