punctured. Lateral reflexed margins of the elytra distinctly 

 terminating at the humeral angle ; the punctuation of the 

 surface of the elytra is in rows of fine punctures, the intervals 

 being convex, interrupted, and forming, especially at apex, 

 series of oblong tubercles. Legs longer and (especially the 

 tarsi) more slender. Body not pilose. 



Artystona Erichsoni, Y^hite [Titcena). 



The TitcBna interrupta^ Redtenb., must be referred to this 

 species, the type specimens of which are in my collection. 



The head is remotely punctui'ed ; the prothorax more closely 

 punctured, with the interstices quite smooth. 



Hah. New Zealand. Three examples in my collection. 



Artystona WaJceJieldi, n. sp. 



Readily to be distinguished from A. EricTisoni by the colour 

 entirely of a dark shining brown ; the head and prothorax 

 much more closely and rugosely punctured ; and, as a secondary 

 character, the intervals on the elytra (especially at sides and 

 apex) are more strongly interrupted and more distinctly tuber- 

 culiform. 



Length 5 lines. 



Hah. New Zealand. Five examples. 



Examples of this species in Doue's collection were labelled 

 ^^ Strongylium volvulunij Klug." 



Artystona rugiceps^ n. sp. 



Of the same colour as the preceding, but smaller ; form 

 decidedly less parallel ; eyes narrower, appearing outwardly 

 conical when viewed from above, a distinct space between 

 their upper margin (which is entire) and the antennary orbits ; 

 these latter very convex, subangulately rounded : head much 

 more strongly rugosely punctured ; the punctures larger, 

 rounder, and deeper ; punctures on prothorax not more 

 numerous than in A. Wahefieldi^ but larger, rounder, and 

 deeper ; the interstices not at all rugulose : elytra sculptured 

 as in the preceding, but the form is elongate-oval. 



Length 3-3—4^ lines. 



Hah. New Zealand. Seven examples. 



This is the species dispensed by Dr. Schaul'uss under the 

 name of ^^Helops ? j^orcatus.^' 



Callismilax, n. g. 

 Differs from Titcena in the prosternura being vertical and
