OF NEW ZEALAND. 393 



their margins most distinct near the shoulders ; their sculpture in front 

 consists of rows of fine distant punctures, but towards the sides and 

 apices of rather deep striae ; the first and second interstices attain the 

 apex ; the third and seventh are united at the end, thus insulating the 

 intermediate ones ; the two outer rows or striae are abbreviated, and the 

 marginal channels are coarsely (but not at all deeply) punctured. The 

 antenna extend backwards to the base of the thorax, are stout, with the 

 five last joints obviously dilated, the eleventh being larger than the 

 tenth and obtusely rounded ; the second is as long as the exposed part 

 of the first ; the third longer than fourth, which is about equal to the 

 fifth ; the basal joints are almost nude, the five terminal ones are pubes- 

 cent. The prosternal process projects into the cavity of the meso- 

 sternum, and is impressed. The femora are not clavate, the tibia are 

 somewhat arcuated and pubescent towards the extremity, and the last 

 joint of the hind tarsus is nearly as long as the rest. Under-side 

 shining, punctulated. 



Length, 4 lines ; greatest breadth, nearly 2 lines. 



I found two examples at Whangarei Heads ; but, for my first speci- 

 men, I am indebted to Miss Alice Aubrey. It may, I think, be con- 

 sidered an aberrant form. 



Group-AMARYGMID^E. 



The labial palpi moderately separated at the base. Inner lobe of 

 the maxilla unarmed. Mandibles entire at their extremity. Head ver- 

 tical when in repose, immersed in the thorax as far as the middle of the 

 eyes, their orbits prominent. Eyes more or less large, strongly emargi- 

 nate, more or less separated above. Antenna variable. Scutellum 

 large. Elytra feebly embracing the body. Legs more or less long, 

 unarmed. Projecting intercoocal process of variable width. Metasternum 

 elongated ; its episterna parallel. Prosternum very short in front of the 

 anterior coxae, forming a more or less distinct chin-piece. Body winged. 



Amarygmus. 



Dalm.; Lacord. Hist, des Ins. Coleop.^ Tom. v.,/. 473. 



Mentum almost trapezeiform, margined laterally. Ligula cordiform, 

 its anterior lobes widely rounded. Last joint of the labial jtajdf like an 

 equilateral triangle ; that almost transversal, subsecuriform. Labrum 

 truncated or rounded in front. Head immersed in the prothorax up to 

 the eyes, not at all (or very slightly) concave in front. Antennal orbits 

 in general small. Antenna distinctly longer than thorax, slender, first 

 three joints very elongate, four to ten obconical, decreasing in length 

 and gradually but slightly thickening, eleventh oblong-oval. Prothorax 

 transversal, narrowed, and scarcely (or not at all) emarginated in front, 

 rounded laterally, with a wide but slight basal lobe. Scutellum almost 

 curvilinearly triangular, acute at the end. Elytra oval or elliptically 

 oval, more or less convex, a little wider than the thorax, widely hol-
