198 REVISION OF THE AUSTRALIAN CURCULIONIDiE, 



Decilaus memnonius, Pasc; Mast. Cat. Sp. No. 5473. 



(Acalles inemnonius, Pasc.) 



Glabrous except for a few indistinct pale yellow scales. Legs 

 sparsely, pectoral canal not squamose. 



Head large, with large round punctures, smaller (but still large) 

 on vertex than between eyes. Rostrum feebly increasing from 

 base to apex, moderately strongly but not densely punctate, 

 punctures not confluent. Scape short, very slightly longer than 

 two basal joints of funicle, inserted slightly nearer base than apex 

 of rostrum and not extending to apex. /^ro^Aoracc rather strongly 

 transverse; with large round punctures very uniform in size, 

 except that at apex they are smaller. Elytra subcordate, widest 

 about the middle, thence arcuate to apex ; striate-punctate, 

 punctures large, round or almost round, feebly or not at all open 

 posteriorly; interstices at suture the width of, towards the sides 

 slightly wider than punctures, convex, with scattered minute 

 punctures and without granules. Metasternum with a distinct 

 transverse impression on each side. Basal segment of abdomen 

 with moderately large punctures, intercoxal process with a distinct 

 transverse sulcus on each side, separated by an impunctate ridge; 

 2nd segment with very large punctures or fove?e, the suture 

 between 1st and 2nd marked with large punctures; intermediates 

 each with a row of about eight small but distinct punctures 

 across the middle. Length 2>\, rostrum 1 (vix); width 2; varia- 

 tion in length 3J-5 mm. 



Hab. — W.A. : "King George's Sound" (Pascoe); Bridgetown, 

 Donnybrook (Lea). 



May be readily distinguised from any of the preceding species 

 by the shortness of its scape and the position of its insertion. 

 One of the following species [D. cribricollis), however, resembles 

 it in this respect. 



Decilaus moluris, n.sp. 



Upper surface, head, and pectoral canal glabrous. Under 

 surface and legs with rather long white setose scales.
