the posterior segments; four basal segments finely transversely 

 corrugated at apex; apical segment with a strong acute spine on 

 each side. Posterior tibioi with a comb-like series of setae at the 

 outer apex; joints of the front tarsi greatly inflated. Length 4|, 

 to apex of elytra If mm. 



^a6.— Upper Ord River, N.W.A. (R. Helms). 



A small apterous species in build resembling (E. Andersoni, 

 but the head narrower, prothorax with rather larger and more 

 regular punctures, and the abdomen differently coloured. The 

 punctures at the base of the four basal segments of the abdomen 

 (on both surfaces) and less noticeably on the 5th, become more or 

 less confluent, so that these segments appear to be supplied with 

 numerous short regular longitudinal ridges. A somewhat similar 

 appearance (but less pronounced) is to be seen in ffi". Andersoni. 

 The prothoracic punctures show scarcely any trace of a seriate 

 arrangement, except on each side of a scarcely traceable median 



space. 



CEdichirus Andeksoni, Blackb. 



Two specimens from the Swan River. W.A., agree with the 

 description of this species, except that the}' are somewhat 

 smaller (7 mm. only). 



CEdichirus p^deroides, Macl. 



This species has ample wings; a character not noted in the 

 original description. I have taken specimens on the Clarence 

 River, N.S.W. 



P.EDERUS sparsus, Fvl. IIab.— K.iiima, N.S.W. 



P. ANGULicoLLis, Macl. Hah. — Clarence River, N S.W. 



P. ANGULATUS, Macl."^ ffab. — Tasmania, New South Wales. 



P. SiMSONi, Blackb. Ilab. — Tasmania (widely distributed). 



P. TwEEDENSis, Blackb. Hab. — Tweed, Clarence and Hawkes- 

 bury Rivers, Sydney, N.S.W. 



* I prefer to regard this species as a good one, rather than as a variety of 

 cruenticollis.
