30 REVISION OF THE AMYCTERIDES, vi., 



(Eiic. calopliylla), but they take to several other trees, uot all Euealypts. I am 

 also of the oijinion that the larvae teed ou the roots of grass-trees, but have so 

 far got no proof. It is mostly in gra.ss-tree country that the whole sub-family 

 abound, although I have got a few far from such country. Dead and living 

 grass-trees attract members of the Family, but for what purpose I do not know. 

 Of all the species I have taken on and in, grass-trees, I have seen no signs of 

 foliage or leaf base having been touched by them; most of the species taken in 

 dead grass-trees are found in small cavities which they seem to have dug in the 

 decaying heart or pith, but 1 do not think they have pupated there, as the cell is 

 clearly the work of the adult, who prefei-s the decaying heart of the grass-tree as 

 food, the larval and pupal stages being passed in the roots?" 



"Of the species under loose bark on trees, they eat the bark from within out- 

 wards, leaving- the sap alone so that they do not interfere with the health of the 

 tree, except that they keep the bark loose and so help other agencies to work on 

 the trees. I have taken over a dozen on one tree on many occasions. Most of 

 the species taken on the ground { all genera) are mostly at the foot of a tree with 

 fresh bark lying around, on which they have been feeding, this particularly applies 

 to Cubicorrlupiehus, and these are sometimes taken under the loose bark on 

 the trees. Several others seem to live in or on decaying timber such as Ae. 

 (Cubi.) maximiw, which is only to be taken under rotting timber or 

 stones, and nowhere else, and always on rough stony or hilly country. Those 

 species taken on the hilly country arc rarely met with on the san<ly plains and 

 vice versa." 



Mr. (lark has also furnished me with a list of Western Australian Am)/cter- 

 ides known to him, with notes as to habits, etc., from which I have taken the fol- 

 lowing entries relating to individual species of Acantholophu>:. 

 "A. gladiator Pasc. — I have taken about a dozen, but always in tussocks or other 



small thick-gi-owth. I tire the dum]) and drive them out. 

 A. transitun Mad. — About 7 specimens taken, all on the ground under bits of 



timber, etc. I can get this species in one place only, it seems somewhat rare. 

 A. amt/cteroides Mael. — Numerous in dead grass trees, iuid under loose l)ark of 



various trees, also a few amongst the foliage of living gra.ss-ti'ces and some- 

 times under logs. 



This and the following species seem to prefer the hilly country, iuid are 



the most commonly met species. 

 A. sutiiralifi Boliem. — Similar to above, but is sometimes talcen on the Uiw sandy 



country. 

 A. spitiosuf: Mad. — Confined to the low sandy country, and usually on the ground 



under timber, bark, etc., but sometimes taken uiuicr loose bark on trees. A 



peculiar feature of this species is that they usually occur in p.iirs, Imt not 



"in cop/' and never numerous. 

 A. aureohis Bohem. — Usually under loose bark or in dcail gra.ss-trees . Mostly 



on the hills. 

 A. nasicornis Pasc. — One specimen, uiidcr timl)er on gnuuid. 

 A. niiieovitlatu-'i Blackb. — Always on the ground, under logs, oic. 

 A. hiipoleucus Bohem. — On the ground, and under loose 1)ark; liilly country. 

 A. dumo^its Bohem. — Same as above. 



A. cra^fidetiti Macl. — One specimen only, under bark of Mai'ri. 

 A. humeralin Mad. — T have never taken this species. 

 ^4. hiistrix Bnlieni. — Not taken by me.
