200 Mr. Arthur M. Lea's Revision of the 



surrounded by a-narrow acutely raised continuous carina, 

 almost in the shape of the figure 8, In cristatifrons the 

 median excavation is of very different shape, being large 

 at the base and open in front and seen from behind a 

 much stronger and more acute elevation appears on each 

 side of it. The armature of the elytra is also not sharp 

 pointed and projects more downwards. 



There is another species allied to cristatifrons but with 

 the head crested as in the present species and the armature 

 of elytra smaller. But the only specimens of it I have 

 seen (and which are in the Macleay Museum) are not in 

 condition to be described. 



Carphurus fasciculatus, n. sp. 



^ . Flavous ; middle of base of head, elytra (except suture), tip 

 of abdomen and base of each of tlie other segments (except the 

 penultimate), meso- and metasternum, coxae four hind femora and 

 seven terminal joints of antennae black ; tarsi more or less dark. 

 Head with two fascicles of black hair.'^, the fascicles conjoined at 

 base ; sides with straggling blackish hairs, distinctly denser in front 

 of prothorax than usual. 



Head elongate ; indistinctly punctate, base ti'ansversely strigose ; 

 irregularly excavated between and behind eyes, the hinder excavation 

 deep and quadrilobed, of these the median lobes are smaller but 

 deeper than the others, and partly concealed by the fascicles. 

 Antennae comparatively short and stout, 3rd-10th joints obtusely 

 serrate, 11th the length of 10th and obtusely notched at apex. 

 Prothorax distinctly longer than wide, not much narrower than 

 head, apical two-thirds sub-parallel, thence rather rapidly diminishing 

 in width to base. Elytra not much wider than front of prothorax ; 

 with dense moderately small but sharply defined punctures ; sides at 

 basal third suddenly and strongly incurved, thence gradually 

 dilated towards apex. Basal joint of front tarsi as long as the two 

 following combined, inner margin straight and black rimmed. 



Length to apex of elytra 5, of abdomen 7 mm. 



Hob. N. S. Wales : Richmond River {A. J. Coates). 



Allied to armipennis but readily distinguished by the 

 bifasciculate and differently impressed head and bicoloured 

 abdomen. The bases of the fascicles (which are distinct 

 from all directions) are on the lobe between the two sub- 

 basal excavations. The elytra have a slight purplish gloss 

 and the suture is very narrowly pale.
