Afeamirenieiifs ht fnil/iotetres. — Total length 55; width of 

 second segment T*"), of fitth 9. 



Loc. Victoria Mountain, New Guinea. 



In the form of its keels, as in other features, this species 

 would seem to resemble Phityrrhacltis pergranulosxis of 

 iSilvestri (Ann. ^Iiis. Oenova, xxxiv. p. G39, 1895), from 

 j\Iaroka, in New Guinea; but the statement "segmentum 

 prinium angulis anticis rectis, valde productis " does not 

 apply to the first tergite of victorke, in which the lateral 

 angles have the form of a conical triangular tooth. 



The structure of the copulatory feet of Lorice, Silvestri {loc. 

 cit.)j and percjranuhsiis does not seem to be the same as that 

 presented by E. man/aritatus ; E. Lories further differs in 

 colour and peryranulobiis in the form of its keels from 

 marfjaritatus. 



DiODONTODESMUSj gen. nov. 



Allied to EutrachyrhocJiis^ but with the keels larger and 

 liigher, body less convex, the anterior cylindrical portion of 

 the segments smooth ; the area between the tubercles on the 

 dorsum also smooth, and the suture not sculptured. 



Copuh\tory foot of male ending in two simple branches 

 directed inwards. 



Type D. Woodjordi^ sp. n. 



Dioduntodesmus Woodfordi, sp. n. (Fig. 17.) 



$ . — Colour (of dry and probably faded specimen) a 

 tolerably uniform greyish black; the cylindrical half of the 

 segments white above, with a median dark stripe. 



Length of antennce less than width of first tergite. 



First tergite granular, with only the posterior row of 

 tubercles distinct, its anterior border evenly convex from the 

 rounded angular lateral prominence ; second and tiiird 

 segments also granular throughout, with largo depressed 

 keels. The rest of the segments very sparsely granular 

 above, almost entirely smooth on the posterior end of the 

 body, much more coarsely granular on the keels, the anterior 

 lines of tubercles weak, the posterior conspicuous. Keels 

 ■with anterior and posterior borders denticulate, anterior angle 

 rounded, posterior angle acute but not spiniform j lateral 

 margin lightly sinuate ; keels of segments 2 to 13 directed 

 obliquely forwards, keels not shouldered basally.
