32 REVISION OF THE AMVCTERIDES, vi., 



rence of thi^ species and of A. kiimeralis Mael., in western Victoria furnish in- 

 stances of disconnected distribution which are ahnost unparalleled among the 

 Ainyeterides. 



ACANTHOLOPHUS APICALIS Macl. 



Macleay, Trans. Ent. Soe. N.S. Wales, i., 1865, p. 276. 



<?. Closely allied to A. dumosus Boh. Black; clothing indistinct, greyish, 

 somewhat denser on sides. 



Head rather deeply concave in front, with three indistinct impressions above, 

 converging on concavity; Lntercristal ridge well developed, more strongly curved 

 backwards at ends; supraorbital crests simple, arising to a gi-eat extent from 

 behind the ends of ridge. Kostrum somewhat longer and narrower than in A. 

 dumosus, lateral margins slightly sinuate in middle, obtusely angulate anteriorly; 

 internal ridges distinct, strongly convergent; basal foveae large and deep. An- 

 tennae with second joint of funicle hardly longer than firet, club large, not 

 pedunculate. Prothoras with median area free from granules, submedian 

 tubercles distinctly lai-ger and obtusely conical, not in single series, the central 

 ones more outwardly placed; lateral tubercles as in ^4. dumosus. Elytra narrower 

 and considerably longer than in A. dumosus; granules larger, more distinct and 

 more regularly set; tubercles smaller, conical but less acutely spiniform; first row 

 with 11 — 13, the basal tubercles small and rounded, the last 2 — 3 becoming larger 

 and more conical and acute, ending on edge of declivity; second row with eight, 

 rather closely set, conical tubercles, larger posteriorly, and reaching a lower level 

 on declivity than first row; humeral tubercle lai'ge and conical; third row with 5, 

 the first large and conical, the others becoming progi-essively smaller; a pair of 

 strong subapieal tubercles pre-sent. Ventral surface not strigose, rather closely 

 set with fine decumbent setae arising from small, shallow punctures, somewhat 

 more evident on apical segment. Legs with intermediate tiliiae notched. 



$. Larger, more ovate; elytra broader, witii tubercles ledueed to mere 

 granules, hardly larger than the other granules, only the last two of first, and the 

 last three or four of second row at all larger and conical, though smaller than cor- 

 responding ones in c?; humeral tubercle and fii-st tubercle of third row moderately 

 large, followed by a row of (5 granules ; subajjieal tubercles large a-< in male. Vcntci- 

 convex. Legs simple. Dimmsioiis: d' 18 >< fl mm. 



Hah. — South Australia: Mt. Lofty. 



Closely allied to -1. dumosus Bohem., the present species may l)e distinguisiied 

 by its more elongate form, with the presence of large subapieal tubercles, and by 

 the differently sculptured ventral surface. 



On the name label of this species in the Macleay Museum there are two males; 

 as is usual neither is marked as type. 



ACANTHOLOPHUS AJIYCTEUOIDES Macl. 



Macleay, Trans. Ent. Soc. N.S. AVales, i., 1865, p. 271. 



J. Large. Black; moderately densely clothed with brown subpubescence; 

 elytra with a gi-eyish vitta posteriorly between the fii'st and second rows of 

 tubercles, extending down and most marked on declivity, with another, somewhat 

 interrupted, between second and third rows; sides with a grey vitta running 

 along middle of sides of prothorax aiid idmig luwcr margin of elytra, with m lew 

 macules above on elytra.
