/lab. — Western Australia: Lawlers (W. du Boulay). 

 Type (unique) in National Museum. 



In general appearance fairly close to int err upturn, but 

 prothorax without a niedio-apical projection, each projection 

 in front of the subbasal carina semi-double, and not with the 

 appearance as of parts of an interrupted carina, and the 

 elevations on the head very different. The semi-double 

 tubercle on the head is slightly longer than the second tooth 

 on the front tibiae. 



LlPAROCHRTJS DILATATTFRONS, Blackb. 



L. timid-us, Arrow. 

 A specimen of dilatatifrons was sent to Mr. Arrow for 

 his opinion, and in reply he wrote that it was identical with 

 timid us; the former name has priority. 



Pararhopaea. 



In his table of the "True Melolont hides" (ante, 1911, 

 pp. 187, 18S) Blackburn distinguished this genus by "Labrum 

 strongly directed forward, almost horizontal," as against 

 "Labrum vertical or nearly so" of Rhopaea and Pseudo- 

 holophylla. The type of the only previously described species 

 of Pararhopaea (callabonnensis) is in the Museum, and its 

 labrum appears to be quite vertical to the long axis of the 

 body ; in fact, it appears exactly on the same plane as the 

 basal portion of the clypeus, and almost at right angles to the 

 front elevation of that organ. In Rhopaea it is directed at 

 right angles to a straight line continuing the base of the 

 clypeus, and gently diverges from a line continuing its front 

 elevation. 



Pararhopaea gigas, n. sp. 



d" . Bright castaneous, some narrow margining parts 

 black or blackish. Densely clothed with long yellowish hair 

 en sterna, parts of legs, junction of prothcrax and elytra. 

 hind margin of scutellum, and basal joint of antennae; 

 upper-surface with very short, sparse, depressed, whitish 

 setae. 



Head with two feeble elevations between eyes ; the 

 punctures there dense, large, shallow, and reticulate, about 

 base much smaller and sparser; clypeus with elevation high 

 and bilobed, in middle of apex much less elevated than at 

 sides; labrum widely and deeply notched, with numerous 

 setiferous punctures. Antennae with first joint large and 

 obtriangular, second small, third-tenth forming a curved 

 flabellate club. Apical joint of palpi with a wide, shallow 

 depression. Prothorax about twice as wide as long (14 x 7.1 

 mm.), sides crenulate and subangularly dilated near the
