50 ON THE PSELAPHIDiE OF AUSTRALIA, 



et capitis longitudine, stria suturali nulla discoidali ; abdom- 



ine sub lente setoso, elytris angustiori, marginato. 



Long. -Y%o po]l- Common under stones in grass. Parramatta. 



The head and thorax are free from setse, and the thorax is also 



free from the impressions so common in this genus. The large 



size of the elytra at once distinguish this species from all the 



preceding ; the antennoB are of the ordinary form. The tibia of 



the fore-legs of the males are thickened at about the middle. 



After death this species becomes almost black in many specimens.

 Pallida castaneus, capite polita non impresso ; collo brevi ; 

 thorace breviter obcordato ; elytris magnis, capitis et thoracis 

 longitudine ; abdomine setoso. 

 Long. -j^. Under stones. Parramatta. 

 This species closely approaches B. polita ; its small size, light 

 colour, and the absence of the characteristic impressions on the 

 head, together with the shortness of the thorax and of the antennee, 

 clearly distinguish it. The antennJB have the first joint long ; 

 second globose ; the five following (3-8) very short ; the ninth is 

 transverse ; tenth also transverse and large, nearly as wide as the 

 eleventh, which is large and oval truncate ; the three last forming 

 the club, are longer than the five preceding. I have found but a 

 single specimen, under a stone in the grass.
