doubt, a different epecica (I should judge Westwood's figure to 

 represent a female). The only locality indicated for the specimen 

 of P. rohusta was " AVest Austi'alia."

" This remarkable insect is from Australia, and appears to be a 

 "genus intermediate between Olapliyr.us and Chasmatopterus.^'

Castanea, nitida, capita pedibusque piceis ; prothoracis lateribus et 

 parte anteriore fortiter punctatis, lioc etiam hirsuto ; tibiis poster io rib us

Head pitchy, rather coarsely and closely punctured, with a space in the middle 

 leas punctured. Thorax shining, coarsely and rather closely punctured, except a 

 largo space behind, which is nearly impunctate ; the front part is clothed with rather 

 long and scanty hairs. Elytra chestnut-yellow, very shining, and very nearly im- 

 punctate. Pygidium extremely finely punctured. Under-side densely clothed with 

 woolly pubescence, except that the three or four apicul segments of the abdomen are 

 bare. Legs pitchy, the teeth of the front tibim much developed, hinder libi© strongly 

 dUated at the extremity. 



Of this species I have before me three specimens from Free- 

 mantlo ; they present no evident sexual distinctions, and I suspect them 

 to be all females. I have also another specimen, coming, I believe, 

 from the more northern parts of Australia, which is considerably 

 smaller and narrower than the Freemantlc individuals, and has the 

 tibia) not quite so stout : whether it be the male of P. tecta, or only a 

 small individual of the female sex thereof, I am unable to say.
