HOLCOCERA CONFLUENTELLA Dietz. 



Holcocera confluenteUa Dietz, Trans. Amer. Ent. Soc, vol. 36, p. 36, 1910. 



Two specimens of this species were reared (under Hopk. U. S. No, 

 12170e-3) by the writer from cuttings of Pinus rigida infested by 

 Evetria frustrana and a Recurvaria, species. Moths issued May 14 

 and 15, 1915. Larvae collected at Sharon Heights, Massachusetts, 

 (Heinrich) September 23, 1914. The specimens agree in every detail 

 with Dietz's cotype in the United States National Museum col- 

 lection.

 under sides. Face, head, thorax, antennae, and fore wings a pale, 

 dull, golden yellow. Antennae deeply incised above basal joint. 

 Fore wings shading to a slightly darker yellow near apex; cilia con-

 ing to pale fuscous. Abdomen silvery yellow above; silvery on under 

 side. Legs pale yellow heavily dusted with dark fuscous; the outer

Hahitat. — Ashland, Oregon. (P. D. Sergent and J. E. Patterson.) 



Food plant. — Pseudotsuga taxi^olia. A good series of moths reared 

 (under Hopk. U. S. Nos. 108087(., 10834, 108346-4, 12536A:, 13266e, 

 14280^) from larvae feeding in cones infested by Evetria colfaxiana 

 Kearfort. Moths issued May and August. 



Ti/ve.— Cat. No. 21811, U.S.N.M. 



A fine, pale golden species near inconsjncua Walsingham, but easily 

 distinguished because of the total absence of markings or fuscous 

 scalingson the fore wings. Named in honor of my friend August Busck 

 whose guidance and authority in the study of Microlepidoptera I 

 gratefully acknowledge.
