1921] Surgonopod.s of Mccoptera and Neuroptera 151 



to those of the male, while the secondaries have a terminal po\v- 

 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 $ , 

 3 paratypes S and one paratype ? , from the Hualapai Mts., 

 Mohave Co., Ariz,, May. One paratype $ from the Planet Mine, 

 Bill "Williams E., Yuma Co,, Ariz., and four paratypes 9 from 

 Mohave Co., Aug. In addition we have specimens from Yavapai 

 and Cochise Counties, Ariz. 



We place this species after umhrata Wlk. and its forms, though 

 it is not closely related. Its superficial appearance suggests Fen- 

 tonia miranda Dyar, l)ut it is a true Ileferocainpa and this resem- 

 blance is only general. 



NOTE ON" THE SURGOXOPODS OF CEETAIX MECOP- 

 TERA AND NEUROPTERA. 



By G. C. Cramptox. 



Through the kindness of Mr. A, N. Caudell, I have recently 

 been able to examine a specimen of the interesting Mecopteron 

 Merope tuher, 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 III, 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 

 sho\\'n 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.
