This strikingly beautiful shell, tlioug-li havin.s; points of 

 resemblance, may be very readily distin.<>uislied from its 

 congeners. Compared with L. dehurghice, Reeve, it is much 

 more elevated and acute, and the produced scales or spines at 

 the angle are much narrower and more erect. Compared 

 with L. diudeina, A. Adam.^, it lias no second angle or armed 

 heel below the periphery, where it is convexly rounded, and 

 the spines at the angle are not hooked, but obliquely erect 

 and sharp.

A beautifully sculptured species, somewhat resembling 

 C. consors, Lischke, but with a higher, more acute spire; and. 

 while that species is comparatively smooth, this is closely 

 covered with narrow ridges of unequal size, but all densely 

 beaded with sharp prickly scales or nodules. 



L. — A Revision of the Asilidse of Australasia. 

 By Gertrude Ricardo. 



In a collection of Diptera sent me several years ago by 

 Mr. French from the Mclboui;ne Museum, for determination, 

 were a certain number of Asilidse. In attempting to name 

 them I found great confusion in the nomenclature of tiie 

 species, and of their generic place, from Australia. The 

 following paper is an attempt to clear up some of these 

 errors, but no doubt there will still be much to revise when 

 more material is available. The majority of the old species 

 were described by Macquart and Walker, who both woiked 

 at about the same time — Walker from 1849-1856 and 

 jNIacquart from 1838-1855; in consequence there are very
