Australian and Tasmanian Malacodermidae. 61 



Metriorrhynchus femoralis, Macl., Trans. Ent. Soc, 

 N.S.W., II, p. 262. 



Mr. Rainbow informs me that the rostrum (not men- 

 tioned in the original description) of this species is as 

 long as in rliipidms (a specimen of Avhich I sent to the 

 Australian Museum for comparison), and that the elytra 

 of the male (as implied in the description) are unicolorous.

Metriorrhynchus nigripes, Macl., /. c, p. 262. 



Porrostoma clegans, Wat., Trans. Ent. Soc. Lond., 1877, 

 p. 75, PI. I, figs. 23-27 ; 111. Typ. Col, p. 44, PI. XI, figs. 

 6-6te. 



The original description of this species is simply a com- 

 parison with the preceding one and is very unsatisfactory ; 

 but there are two co-types before me and these agree 

 exactly with Waterhouse's description of degans. 



The species is variable to a slight extent, the dark 

 markings in the three posterior areolets being variable in 

 size and intensity, and in one specimen before me are 

 entirely absent ; the scutellum is occasionally entirely 

 black, but usually its sides are reddish.

Metriorrhynchus ampliatus, Macl. {Xylobanus), 

 P. L. S., N.S.W., 1887, p. 233. {Fig. 80.) 



The elytra of the type were described as being of the 

 " usual quadricostate sculpture " and the prothorax as 

 having "the discal areolet narrow and extendino^ to the 

 apex." These remarks are quoted, as on examination of 

 the Macleay Museum types I noticed that Macleay had 

 confused two species under the name ampliatus. Of these 

 species one specimen agrees with the quoted remarks ; its 

 elytra have the usual four strong costae which on the 

 basal two-thirds separate two double rows of punctures, 

 towards the apex, however, the punctures become irregular. 

 The other specimen has the elytral punctures in single 

 series and the median areolet of the prothorax connected 

 with the apex by a carina, but in colour it exactly agrees 

 with the type ; this sj)ecies appears to be the more common
