SOME APHIDID.^ OF THE GENUS NECTAROPHORA FROM 



NEW MEXICO. 



BY T. D. A COCKERELL, EAST LAS VEGAS, N. U. 



Nedarophora rudbeckice. (Fitch). 



Hab. — Beulah, N. M., alt. 8,000 ft., very abundant on Rtidbcckia 

 ampla, A. Nelson. It is preyed upon by Hippodamia conver\^cns. This 

 species is easily known by its bright scarlet colour. Monell reports A^. 

 rudbeckia from many genera of CompositcC at St. Louis, Mo. ; in New- 

 Mexico I have found it only on one species of Rudbeckia ; even the 

 species on Rudbeckia hirta is quite different. 



Nedarophora solidaginis (Fabr.). 



ffab. — Beulah, N. M., July 26, numerous on Solidago. Blackish- 

 red, some almost black ; nectaries black ; cauda light yellowish ; stigma 

 pale greenish (yellowish in N. rudbeckice) ; femora with basal two-thirds 

 pale yellowish, distal third blackish. The very young may be slightly 

 tuberculate dorsally. Many of the young are bright red. In the winged 

 female the cauda is just half the length of the nectaries ; the latter are 

 imbricated. 



This species is very near to N. rudbeckice, but evidently distinct. 

 It agrees with Buckton's account of European JV. solidaginis in all 

 essential particulars ; Buckton's description and figure indicate a black 

 cauda, but in his table on p. 102 he says it is yellow. The species is 

 new to America, but is evidently native ; a member of the circumpolar 

 fauna. 

 Nedarophora corailorhizce, sp. n. 



Hab.— Bt\\\ah, N. M., July, 1902 {IV. P. Cockerel!). Numerous on 

 Corallorhiza imcltiflora. 



Apterous %. — Green (pale yellow mounted in balsam), without 

 markings; length 2^ to nearly 3 mm.; eyes scarlet; cauda pallid; 

 nectaries very long, colourless at base, blackish in middle, paler beyond, 

 but blackish again at the extreme tip ; antenna; pale, dusky at ends and 

 at the joints ; legs pale, apical portion of femora dusky ; tarsi black or 

 nearly so. Antennae over 3 mm. ; cauda ensiform, about 630 //. ; nec- 

 taries 1400 \t.; antennal joints measuring in //. ; (r.) prox. 150, (2 ) 100, 

 (3-) 1 130, (4-) 920, (5.), 730, (6a.) 150, (6b.) 1020. 



Nectaries slender, often curved outwards towards the end. Sensoria 

 few, on under side of basal half of third joint. 



N. lutea, Buckton, found on greenhouse orchids, is yellow, with a 

 large dorsal dark brown spot, and has much shorter nectaries. N.
