266 REVISION OF THE AUSTRALIAN CURCULIONID^E, 



applies to the two specimens which I think are females of P. 

 a-ffiuens. 



PsYDESTis AFFLUENS, Pasc; l.c. No. 5404. 



Reddish-castaneous ; head, scutellum and suture of elytra 

 piceous, a few elytra! punctures stained with piceous ; under 

 surface piceous, legs paler; antennte pale red, club slightly darker. 

 Head with scales at base, rostrum glabrous. Prothorax with 

 ochreous scales leaving five dark spots across the middle; of these 

 the three median are connected across middle, the median also 

 with apex and the two others with base. Elytra with numerous 

 small patches of yellowish scales. Under surface with ochreous 

 scales, moderately dense at sides of middle of basal segment of 

 abdomen, apical segment glabrous on apical half. Legs moder- 

 ately densely clothed. 



Head densely punctate. Rostrum parallel-sided to antennae, 

 feebly incurved between antennae and apex ; densely punctate, 

 punctures not much smaller near apex than at base. Punicle 

 with the 1st joint slightly longer than 2nd. Protliorax densely 

 punctate, punctures more or less concealed. Elytra striate- 

 punctate, punctures rather large but shallow; interstices raised 

 and all acutely ridged in middle. Under surface rather densely 

 and strongly punctate; a depression on metasternum and Ijasal 

 segment of abdomen, the depression bordered by rather large 

 scales; the three intermediate segments slightly curved at sides. 

 Length 4, rostrum 1 J; width 2f mm. 



Hah. — "Western Australia" (Pascoe), Geraldton (Lea). 



I have described the clothing as I found it, but it is probably 

 not at all constant. 



Two specimens under examination are probably females. They 

 differ in having the rostrum more rounded and less coarsely 

 punctate; thinner antennse with a shorter scape (but inserted at 

 the same place); the prothorax is feebly clothed with ochreous 

 scales and with a few sooty spots; the elytra are feebly clothed 

 with ochreous scales and with two very feeble transverse sooty 

 fasciae; the metasternum and basal segment of abdomen are not 

 depressed in middle and the scales are larger there than else-
