202 REVISION OF THE AUSTRALIAN CURCULIONIDyE, 



punctate, and the elytra themselves considerably wider, wider in 

 fact than in any other species of the genus (width 3^; length 

 diagonally 3|, horizontally 24 mm.). 



Dkcilaus hispidus, n.sp. 



Clothed with straggling semi-erect hair or very long setfe, 

 mostly black in colour but the prothorax with several feeble 

 clusters of white hairs; elytra with three feeble but distinct stripes 

 of white hairs, one at base, one at summit of posterior declivity, 

 and one hetween summit and apex. Sterna and two basal 

 segments of abdomen with long white setose hair; less with Ions 

 white setfe. Pectoral canal glabrous. 



fiend with large punctures; eyes prominent. Rostrum rather 

 long, irregularly ])unctate, punctures of moderate size, and denser 

 towards sides than middle. Scape long, the length of funicle, 

 inserted two-fifths fi-om apex of rostrum and passing apex. Pro- 

 thnrax strongly transverse, with dense large round and moderately 

 deep punctures. Elytra briefly subcordate, considerably wider than 

 prothorax at base; punctures large, oblong, interstices shining, 

 feebly raised, flat, with very minute punctures and granules 

 towards apex. Basal segment of abdomen twice the length of 

 2nd, densely and strongly punctate, 2nd depressed below 1st, its 

 suture with that segment marked by a row of large punctures; 

 intermediates minutely punctate, the 3i'd distinctly narrower than 

 the 4th. Length 2, rostrum \; width 11 mm. 



Hab. — W.A. : Rottnest Island. 



A small but very distinct species of which I have seen but one 

 specimen. I believe I am right in referring it to Decilaus, 

 although its clothing is at variance with the other species of the 

 genus. The eyes are a little more prominent than is usual, but 

 the rostrum, antenna?, pectoral canal, abdomen and legs are those 

 of Decilaus. 



Decilaus nucleatus, Pasc; Mast. Cat. Sp. No. 5474. 



(Acalles iiucleatus, Pasc.) — I am unacquainted with this South 

 Australian species, but it appears to be a true Decilaus.
