232 REVISION OF THE AMYCTERIDRS, iii., 



yours.'' A male in the Maeleay Collection agrees well with Paseoe's 

 description and figure. The elytra have the first, third, and fifth 

 interstices with numerous fine granules in douhle and multiple 

 series, the second and fourth with much fewer (six on one, nine on 

 the other side), and isolated granules. The fifth ventral segment 

 has an extensive, somewhat boat-shaped excavation at apex, occu- 

 pied by dense golden-brown hair or bristles, which are continued 

 forward to form a dense, median vitta. The length of the fifth 

 segment is greater tlian tliat of the two preceding, but hardly as 

 long as the three preceding combined. Corresponding females 

 have the fifth ventral segment not excavate, and the intermediates 

 longer. Another female has somewhat less rugose, elytral sculp- 

 ture, interstices flatter, and tlie granules more numerous on tlie 

 second and fourtli interstices.

Type, Phalidura draco W. S. Maeleay. 



Large or very large species; male elongate, su])parallel ; female 

 elongate, ovate. Head concave in front, centre of forehead sul)- 

 ti'iangularly raised. Rostrum not separated fi-om liead above, 

 external ridges naming backward along head, internal ridges pre- 

 sent, strongly convergent. Scrobes open posteriorly, extending 

 back to or])it. Eyes subovate, ratlier deeply set, overhung by 

 lateral ridge of foreliead (in M. Boi>idurali, eyes rounded, strongly 

 ]ii-o,iecting). Protliorax strongly transverse, tuberculate or granu- 

 late. Elytra strongly tuberculate on second, third, sixtli, and 

 seventh interstices. Prosternum with a tubercle on eacli side, in 

 front of anterior coxa*. No median ventral vitta present. 



While in tlie ]iast, accepting the name Ami/cferns for the genus 

 under consideration, I have done so with considerable hesitation.
