of Mentzelia Eusbyi, Wooton, Au<^. 2, 1898, Ruidoso, 

 N. M., one mile above Big Rock, about 6800 feet {G. H. T. 

 TownsRnd). 



This is hardly more than a geographical race of H. McLeayi. 



Tenthredo palUcoxa, Provancher, 1878. 



One from Ruidoso, N. M., about 8200 feet, foot of divide 

 between Ruidoso and Eagle Creeks, Aug. 12, 1898 [G. H. T. 

 Townsend). 



This species has only been recorded from Canada, but the 

 present specimen agrees so closely with the description, that 

 we must assume it to be the same. It is 9^ millim. long; 

 the hind femora are entirely yellow beneath, the pale markings 

 throughout being a light primrose-yellow. There is a minute 

 light spot above the base of each antenna, and one at the 

 summit of each eye, as in T. mqjera, Cress. 



Lophyrus Townsendij sp. n. 



? . — Length 9^ millim. ; width of thorax A\ millim. 



Antennse ferruginous, blackish only at extreme tip, 22- 

 jointed. Head and thorax ferruginous ; face up to level of 

 antennse almost entirely yellowish ; cheeks yellow ; middle 

 lobe of mesothorax with a suffused yellow stripe along each 

 lateral margin, and a large black blotch occupying its hind 

 angle; a yellow spot beneath tegulse; a black patch, on 

 which is a yellowish spot, making a sort of ocellus, on pleura ; 

 a small black spot on each lateral lobe of the mesothorax 

 near its lateral margin ; scutellum pale yellow, tipped with 

 ferruginous, its suture with the mesothorax black ; legs 

 ferruginous, the anterior knees slightly yellowish ; wings 

 hyaline, stained with ferruginous, especially about the 

 marginal cell ; abdomen cream-colour, the sutures more or 

 less black, apex dark ferruginous. Head and thorax strongly 

 and rather closely punctured ; the large punctures on the 

 vertex have minute ones scattered between them. Claws 

 w^ith a strong denticle on the inner side. Cross-nervure of 

 lanceolate cell oblique, but only moderately so. 



Hab. South Fork, Eagle Creek, White Mountains, N. M., 

 about 8000 feet, found dead under a pine-tree, Aug. 17, 1898 

 (C. H. T. Townsend). 



A distinct and interesting species.
