244 REVISION OF THE AMYCTERIDES, iii., 



After tlie above des(Ti]itioii of tlie male was drawn up, I received 

 from Mr. Spry, of the National Museum, jNIelbourne, two speci- 

 mens which, though differing considerably from the type, T never- 

 lludess believe are females of this species. 



9. Large, robust, convex. Moderately densely clothed with 

 very minute, broAvnish, subsetose scales, giving the insect a dingy 

 appearance, elytral tubercles not clothed. 



Head and rostrum as in the male. Prothorax (6 x 9 mm.) 

 similar to that of male, slightly more convex, derm not rugulose 

 between the groups of tubercles, lateral group in single series, 

 about seven in number, less promment than in the male, mesial 

 groups similar, flattened, obscure, but about twice as numerous — 

 fifteen to sixteen on each side; the median area broader. Elytra 

 (20 X 12 mm.) convex, ovate, apex with a flange composed of a 

 few granules, and with a strong uuicroniform projection on each 

 side of suture, this latter not granulate; tubercles of hiterstices 

 long, narrow, depressed, the second interstice extending practi- 

 cally to the base, with eleven to fourteen tubercles, almost con- 

 tinuous basally; tliird with ten similar tubercles ending at edge of 

 declivity; fourth with three; fifth with a small humeral tubercle, 

 and with a row^ of four isolated ones from behind shoulder to 

 about the middle: sixth with six, rounded, hardly subconical 

 tubercles, extending from near the middle down the declivity, 

 slightly overlapping fifth; seventh with eight flattened ones, from 

 base to beyond middle. Beneath convex, fifth segment with a 

 transverse apical impression. Prosternal tubercles strongly 

 developed. DimPiidona : 9, 33 x 1 2 mm. 



//a5. — AVest Australia, Nangeran (Enderbee, per F. P. >Spry). 



The differences between these specimens are all of the nature of 

 sexual variation, which exists to a considera])le extent in this genus. 

 The structure points strongly to the relation of these to 3/. ohfio- 

 Jetus. I have descril)ed the tubercles according to the interstices, 

 not according to the rows, as, in these specimens, the arrangement 

 of the seriate punctures can l)e fairly definitely determined, where- 

 as in most species the punctures are crowded out and brokeji u]"»
