sixth, and eighth distinctly punctulated. Legs simple, bearing greyish 

 hairs.

Mr. S. W. Fulton caught two examples in a pool on Mount 

 Maungatua, Taieri, Otago. 



Group PSEL APHIDES. 



Sagola (P. 134)- 



I 573- S. castanea, n.s. Elongate, sub-depressed, shining, 

 rufo-castaneous, head and thorax dark-red, legs and antennas 

 rufescent, tarsi and palpi fulvous. 



Head large, trigonal, its posterior angles so produced as to be as 

 broad as the middle of the thorax, the back part separated, as it 

 were, from the thorax by a deep incision, with a deep central cavity 

 and two small occipital foveae ; it bears fine yellowish hairs. Antenna 

 hirsute, longer than head and thorax, of nearly equal thickness 

 throughout ; basal articulation stout, cylindric ; joints 2-5 rather 

 longer than broad, oviform, second and fourth nearly equal in bulk, 

 third much smaller than the contiguous ones ; 6-10 become shorter, 

 the tenth being quite transversal and larger than ninth, eleventh 

 ovate, larger than the preceding one. Prothorax cordate, shining; 

 with a large depression behind the middle ; two small punctiform 

 fovese behind it (one near each of its hind angles), and a large cavity 

 at each side extending from the base to the middle ; it is smooth 

 otherwise, and is clothed with some fine hairs. Elytra broader than 

 thorax, widest behind ; sutural striae deep and entire, intra-humeral 

 depressions elongate (when viewed sideways they are seen to consist 

 of a basal puncture and two or more larger confluent ones beyond) ; 

 their surface is apparently impunctate, and bears numerous yellow 

 hairs. Hind-body rather longer than elytra, its second and third 

 dorsal segments broader than they, each larger than the first, all 

 three marginated, the others gradually depressed, the basal portion 

 of the first densely covered with very minute, scale-like hairs. Legs 

 of normal structure, tarsi moderately elongate. 



The form of the head makes a near approach to that of S. genale, 

 but the angles are not so acute as in that species, which is also a 

 good deal smaller and very much lighter in colour. 



Length, nearly i J lines ; breadth, f . 



Mr. S. W. Fulton sent me a specimen which he found at West 

 Taieri bush. 



1574. S. excavata, n.s. Castaneo-rufous, legs and antennas 

 fulvo-rufous, tarsi and palpi fulvous, clothed with yellow hairs. 



Head moderate, its widest part in line with (but including) the 

 eyes, rounded behind; with fhe common median depression, two 

 minute foveae behind, its surface appearing as if minutely punctated. 

 Antenna stout, second and fourth joints sub-globular, third small, 

 the others gradually become transversal, eleventh rounded. Pro- 

 thorax considerably dilated laterally at the middle, its length and 

 breadth about equal ; with the usual post-median depression, two
