and species of FseJaphidce and Sc^dmamdce. 513 



The antennae are not compressed, but are slender at 

 their base and gradually thickened to the abruptly trun- 

 cate extremity The ejes are placed at a distance from 

 the back of the head. The thorax is transverse, beino- 

 distinct y broader than long, slightly narrower in froift 

 than behind, and it has a large fovea-like impression in 

 front of the base. The elytra are reddish, their punctua- 

 tion well marked only at the base. The hind body is 

 furnished Avith rather numerous and long erect setse. 



West Australia ; one specimen of each sex collected by 

 Mr. Du Boulay. I have named this species after Mi\ 11. 

 L. King of Paramatta, who has described a considerable 

 number of species of Australian Pselaplndce.

 versim quadrato, ante basin impresso ; elytris flavescentibus, 

 nitidulis, basi summo solo evidenter punctato. Long. 

 Corp. 2 mm. 



Mas, tibiis intermediis apice intus unco acuminato 

 armatis; projiygidio magno transverso, pygidio valde 

 inflexo, nitidulo, impresso ; metasterno valde acuminato- 

 prominulo.

The antenna? are moderately long, distinctly longer than 

 the head, slender at the base, rather stout at the abrii])tly 

 truncate extremity. The head is long, the eyes placed at 

 a considerable distance from its hind part. The thorax 

 is a little broader than long, very slightly narroAved and 

 rounded at the front angles. The seta? of the up]icr 

 surface are very short and fine and sparing, and the 

 surface is therefore more shining than in the other species 

 here described. The extremely prominent metasternum 

 is remarkable.
