19211 Surgonopods of Mixoptera and Neuroptera 151 to those of the male, while the secondaries have a terminal pow- dery whitish area, preceded by a broad vague transverse shade and then by a slender median shade, both of which lose their identity toward the costa.
The discal bar is present. Expanse 35 to 45 mm., the sexes similar.
Described from ten specimens in coll. Barnes. Holotype 8, 3 paratypes 8 and one paratype 9, from the Hualapai Mts., Mohave Co., Ariz., May. One paratype
8 from the Planet Mine,
Bill Williams R., Yuma Co., Ariz., and four paratypes 2 from
Mohave Co., Aug.
In addition we have specimens from Yavapai and Cochise Counties, Ariz.
We place this species after zimbrata Wlk. and its forms, though it is not closely related.
Its superficial appearance suggests Fen- tonia miranda Dyar, but it is a true Heferocampa and this resem- blance is only general.
NOTE ON THE SUEGONOPODS OF CERTAIN MECOP- TERA AND NEUROPTERA.
Through the kindness of Mr. A. N. Caudell, I have recently been able to examine a specimen of the interesting Mecopteron Merope tuber, preserved in alcohol. Since the specimen was pre- served in fluid, this permitted the moving of the parts without danger of breaking them, and enabled me to determine that the parts which I formerly considered to be the dorsal penis valves (i. e., the parts labeled "dv" in Fig. 24, Plate 111, of Psyche, Vol. 25, 1918), from an examination of a dried specimen of Merope in the Cambridge museum, are in reality the surgonopods, or lateral appendages of the tenth abdominal segment. It would also appear that certain of the structures called gonopods in the Neuroptera shown in Figs. 14, 12, etc., of the article in question, are likewise homologous with the surgonopods, as I have pointed out in a paper which will later be published, dealing with the terminal structures of insects in general.
