OF NEW ZEALAND. 385 



elytron with eight rows of punctured striae which are greenish, the spaces 

 between are somewhat raised and divided into oblong tubercles by 

 short transverse grooves, which are green but not punctured like the 

 striae. 



New Zealand (Captain Parry). 



OBS. I found three or four specimens at Whangarei Heads ; they 

 measure six lines in length; the head is remotely punctured, particularly 

 between the eyes, the thorax more closely ; the scutellum is punctulate. 



This is identical with Redtenbacher's subsequently-described Titcena 

 interrupts 



685. A. wakefleldi, Bates; Ann. Mag. Nat. Hist. Readily 

 to be distinguished from A. erichsonii 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 tuberculiform. 



Length, 5 lines. 



New Zealand. 



NOTE. In my unique example, which was received from Mr. Wake- 

 field, the size is less than four lines, and the prothorax is smaller and 

 more transverse than in the preceding species. In all three species the 

 elytral tubercles are very obtuse, in fact they might be more correctly 

 designated oblong-obtuse elevations. 



686. A. mgiceps, Bates ; Ann. Mag. Nat. Hist. 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 the upper margin (which is entire) and the 

 antennary orbits ; these latter very convex, sub-angulately rounded ; 

 head much more strongly rugosely punctured ; the punctures larger, 

 rounder, and deeper ; punctures on prothorax not more numerous than 

 in A. wakefieldi, but larger, rounder, and deeper ; the interstices not at 

 all rugulose ; elytra sculptured as in the preceding, but the form is 

 elongate-oval. 



Length, 3-4j lines. 



New Zealand. 



I have a mutilated example from Mr. Wakefield ; the prothorax is 

 small and transverse. 



OBS. Mr. F. Bates adds, " Examples of A. wakefieldi in Doue's 

 collection were labelled Strongylium volvulum, Klug. The A. rugiceps 

 is the species dispensed by Dr. Schaufuss under the name of Helops (?) 

 porcatus. 



Group HELOPID^E. 



Ligula prominent, its feelers rather distant at the base. Internal 

 lobe of the maxillce unarmed. Last joint of the maxillary/^/ strongly 

 securiform. Mandibles fissile (or not) at apex. Labrum more or less 

 prominent. Head generally prolonged posteriorly from the eyes,
