404 REVISION OF THE AMYCTERIDES, 



apparently situated on tlie exti'i'iial margins; in the two new sjieoies herein 

 flesfribed tliese tubercles are approximated and internal to the margins. It 

 might be que.stioned whether this difference should not be regarded as of generic 

 impoi'tance, but one of the two new species is otherwise ver>' similar to the 

 type species tiioitgh the other differs rather widely in general appearance. 

 The three species may be distinguished by the following table : 



1 (4) Strongly tuberculate species. 



2 (3) Basal rostral tubercles widely separated yl. »it/n\a/i/s Fa,sc. 



3 (2) Basal tubercles approximated A. /asn'ii/us, n.ip. 



4 (1) With obliterate sciUpture, the tubercles obsolescent ... A. ob/i'f grains, n.sp.

Fascoe, Jouru. Linn. Soc, xii., 1873, p. 7, PI. ii., f. (i. 



Elongate, comparatively broad across elytra, small. Black; with dingy 

 brown clothing. 



Head concave in front, not separated from rostrum by a sulcus; with an 

 erect spine on each side above eye. Rosti-um comparatively short and broad, 

 with an erect sjiine or crest on each side of l)ase at lateral margin, slightly out- 

 wardly projecting; dorsal surface concave between crests, then sloping down- 

 wards and forwards to apex; scrobes shoii; ending ojiposite anterior margin of 

 rostral crests. Antennae with scape moderately long, fairly stout. Eyes pro- 

 minent, coarsely faceted. 



Prothorax comjiaratively narrow, the width across base hardly e(|ual to width 

 of el^^tra across the third interstices; lateral margins strongly angulate in front 

 of middle, then sloping to base and apex; apical margin rather strongly pro- 

 duced above, ocular lobes absent; median line depressed throughout, bordered 

 on either side by erect, conjoined tubercles, these forming short jiarallel crests 

 in anterior portion, and ba.sally convergent crests from middle to base; rest of 

 surface non-tubeivulate. 



Elytra very broad, subparallel on sides; base formed by the ]i(irlioii between 

 the projecting ends of the third interstices; fii-st interstice with a raised crest 

 on each side of seutollar region, divergent, forwardly projecting; third and fifth 

 interstices curved with convexity inwards, each with a row of rounded tubercles, 

 becoming larger jjosteriorly and b.asally, not reaching base and not extending 

 down declivity; seventh interstice witii an infra-luinicral tubercle, followed by a 

 row of small tubercles, all contained within the curve of the fifth interstice. 

 Under-surface llattened. Tarsi short.

The above description was drawn up from the type specimen in the British 

 Museum; no measurements were however made, so the length given by Pascoe 

 is quoted. 



No notes were made on t!ie relation of the jiosterior end of the scrobe to 

 tlie eye; Pascoe describes the scrobe as running below the eye, reference to his 

 figure shows that the position is not essentially different from that described for 

 the following species, the interiu-etation of anterior and lower depending on the 

 position of the h'.Md. Ir the generic diagiiosis Pascoe describes tiie rostnim as 

 trituberculate ; this is hardly correct, the three tubercles are shown in the figure 

 but the basal one really represents the supraorbital crest, while the anterior is 

 hardly more than a slight angulation.
