the Australian Longicornia. 561 



this genus between Agapete and Ischnotes. It differs very much 

 from both in habit, those two being very remarkable, although in 

 quite a different way, while Clceadne has a very commonplace 

 look. Of all the Australian forms, perhaps, it comes nearest to 

 Amphirho'e in outline, but that genus, owing to its longer muzzle, 

 belongs to another category of the family. I received my speci- 

 men from Mr. Macleay ; a second in Mr. Bakewell's collection is 

 supposed to be from Adelaide. 



1. Clceadne melanaria. (PI. XXIII. fig. 5.) 

 C. nigra ; elytris singulis lineis duabus elevatis basi griseo- 



hirtis instructis. 

 New South Wales. 



Black, opaque ; head coarsely and closely punctured, very short, 

 and transversely quadrate in front ; eyes reniform ; antennae longer 

 than the body, setaceous, 11-jointed, distant at the base, the first 

 joint short, obcoilic, the third longest, the fourth much shorter, 

 the fifth nearly as long as the third, the remainder nearly equal to 

 the fifth, the last scarcely distinguishable from the preceding one ; 

 palpi short, with the terminal joint ovate ; prothorax ovate, with 

 coarse, crowded punctures, and a few scattered, erect hairs ; scu- 

 tellum triangular ; elytra narrow, parallel, two elevated lines on 

 each, the inner not extending to half the length of the elytron, 

 the outer continued to the apex, the base and both lines clothed 

 with greyish-white hairs ; body beneath and base of the femora 

 chesnut-brown ; abdomen short, gradually tapering from the 

 base. 



Length 5 lines. 



Genus Typhocesis. 

 Caput fronte brevi, quadrata. Oculi reniformes. AntenncB dis- 

 tantes, elongates, setaceoe, articulo basali subpyriformi, tertio 

 quarto longiore, cseteris plus minusve subajqualibus, vel gra- 

 datim brevioribus. Palpi apice subtriangulares. Prothorax 

 rotundatus, disco subdepresso, lateribus dentatis. Elytra 

 brevia, subparallela. Pedes elongati, femora clavata, tars'is 

 intermediis et posticis angustatis, articulo basali elongato. 

 Prosterniim elevatum, subacutum. 

 Uhis genus belongs to the group of which Hemesthocera, Homa- 

 lomelas, Prothema, and Euryarthron are members, differing from 

 all in the form of the prothorax and clavate femora. The angle 

 formed by the depression of the prothorax creates a sort of ridge 

 on each side.
