OF NEW ZEALAND. 1457 



consists of series of moderate punctures and minute tubercles, and 

 the interstices are more or less irregularly and obtusely elevated 

 longitudinally ; a bare, transverse, slightly shining space is bounded 

 behind by concentrated setie and two nodosities ; there are two 

 nodosities near the apex, and the third interstices are a little raised 

 at the base. Legs sparsely clothed with very small setae ; the an- 

 terior tibice on the inside, near the middle, somewhat swollen or 

 curved ; the others have a sort of swelling just above the middle, 

 and another near the extremity, on the outside. The aiitennce are 

 gradually thickened, and become darker and more pubescent, 

 towards the extremity ; their third joint is not twice the length of 

 the second, and it is longer than the fourth. 



Underside variegate, rufo-fuscous, with slender yellow setae ; it 

 is irregularly and, except on the presternum, rather finely sculp- 

 tured ; the fourth and tifth segments are smooth and shining at the 

 base ; the pseudepipleurae bear some coarse, distant granules or 

 punctures, and are nearly nude, the upper part is clothed and sculp- 

 tured in nearly the same way as the breast. 



A glance at the tibite will lead to its identification. 



Length, 3J-3-J- ; breadth, l|-li lines. 



Maketu, Humia Eange. A dozen specimens. The insect lives 

 on the ground amongst fallen leaves. 



Syrphetodes (Gen., p. 351). 



2528. _S. COrdipennis, "-s. Subovate, opaque, variegate, fus- 

 cous, tarsi obscure-red, palpi piceous ; densely clothed with small, 

 depressed, almost hair-like scales, yellowish, rufo-fuscous, dark, and 

 red, these last most apparent on the sides of the thorax. 



Head broadly depressed. Aiiteniue with yellow sette on the two 

 basal joints, the three terminal joints dull-fuscous and finely pubes- 

 cent, seventh and eighth reddish, third twice the length of the 

 second, one-third longer than the fourth. Thorax broader than long, 

 widest behind the middle, the sides nearly straight in front, sinuously 

 narrowed posteriorly ; anterior angles acutely prominent, distant 

 from, but extending as far as the front of, the eyes, basal angles 

 rectangular ; apex sinuously emarginate, with a small emargination 

 in the middle which is a little raised at each side ; there is a large 

 obtuse elevation behind the centre of the disc. Scutelhim trans- 

 verse, raised, blackish. Elytra broader than the thorax at the base, 

 which is curved towards the shoulders, from thence gradually 

 curvedly narrowed posteriorly, with a small sutural notch between 

 the apices ; their surface uneven, with irregular series of compara- 

 tively small punctures, the explanate sides with large fossae ; not far 

 from the suture there are six nodosities, two near the base, two 

 larger ones on top of the hind slope, and two near the middle, there 

 are two more on each side of the dorsum, and sonae small ones on 

 other parts. Legs long ; tibiae straight, variegated. 



This species may be known at once by its large size, and pecu- 

 liarly-shaped, cordiform elytra. The hind slope is very gradual, and
