34 UKVISIOX OF THE AMYCTERIDES, vi., 



lateral borders raised, angiilate in front, posteriorly miming into base o£ supra- 

 orbital crests; internal ridges strongly convergent, only evident at base; basal 

 loveae deep. Antennae rather stout, first joint of funicle shorter than second, 

 club stout, briefly pedunculate. Prothorax flattened; median area with an irre- 

 gular, impressed, median line, set with flattened, little raised granules of varying 

 size; submedian tubercles similarly flattened, noduliform. varying in size and 

 shape, irregularly set ; lateral tubercles broadly triangulifonn, the anterior almost 

 completely conjoined with median, and the posterior as large as median. Elytra 

 moderately elongate, shorter than in ^4. hroicni; punctures small and indistinct; 

 granules small, but regailarly an-anged; first row of tubercles 8 — 9 in number. 

 basal ones small and granuliform, the last 3 — 4 becoming larger and more conical, 

 ending on edge of declivity ; second row with 6 — 7, all conical, but smaller at base, 

 ending at a lower level onj declivity, with a small spicule beyond last tubercle; 

 humeral tubercle large and conical ; third row with 4, conical outwardly projecting 

 tubercles, the first the largest. Ventral surface set with large, rather shallow 

 punctures, the intervals sliglitly raised or strigose, punctures filled with large sub- 

 squamose setae. Intermediate tibiae with a rather shallow subapical notch. 



?. Very large, with broad elytra; first row of tubercles granuliform, the last 

 2 — 3 small conical tubercles; second with 10, all small, but larger than first row. 

 and conical posteriorly; third with 6. Venter convex, obsoletely punctate, with 

 small subsquamose setae in the punctures. Dimensions : <S. 1% ^ 7 mm. ; S. 23 X 

 9.5 mm. 



Hab. — Western Australia: King George Sound, Coreongenup, Swan River. 



A male from Swan River has the ventral segments all coarsely punctate with 

 the interstices raised and strigiform. 



On the name label in the Macleay Museiun are two males from Swan River; 

 one hiis the ventral sculpture almost obsolete as in the c? described above, the other 

 is coarsely strigose as in the Swan R. male; the tubercles are 8 — 9, 7 — &, 3 — 4 in 

 the one male, and 8 — 9, 7 — 9, 4 — 5 in the second. The difference in the sculp- 

 ture of the ventral segments I cannot regard as of specific value; it seems more 

 probably an individual variation. 



Apart from the following species, ^4. browni Ferg., the present one is most 

 closely related to A. amycteroid-es Macl., but differs, inter alia, in the flattened 

 prothoracic tubercles.

Ferguson, Trans. Roy. Soc. S. Australia, xxxix., 1915, p. (Hi. 



This species is closely allied to ^4. transitus Macl., but may be readily dis- 

 tinguished by its much more elongate form, with more numerous and smaller 

 elytral tubercles.
