Co., Ai'iz. However, as I have shown, unistriganus is a synonym 

 of laticapitanus. 



Remarks. — This subspecies very closely resembles both lati- 

 capitanus and clarkei in general appearance and genital structiu-e, 

 but it may be distinguished from the former by its antennae, each 

 segment of which bears only one complete ring of scales, and it may be 

 separated from both by the shape of the cucullus of its harpe. This 

 subspecies is named in honor of Carl Heinrich. 



30e. Acrolophus laticapitanus clarkei, new subspecies 



Figure 149 



Female unknown. 



Male. — Labial palpi ochreous, short, weakly recurved, gradually 

 diverging from head and from each other distad. Eyes large, pro- 

 truding, without setae or lashes. Antennae simple; segments robust, 

 subglobose, each furnished with one complete ring of ochreous scales. 

 Head, thorax, and forewings pale yellow. Forewing with faint, 

 irregular, fuscous, diagonal streak near center; apex and outer margin 

 sparsely and minutely dotted with fuscous. Hindwings and abdomen 

 fuscous. Genitalia as in laticapitanus except for cucullus of harpe 

 (fig. 149); cucullus somewhat constricted at base, major portion 

 considerably and irregularly expanded, apex very broad and with 

 narrowly rounded dorsal portion developed further distad than broadly 

 rounded ventral portion. Expanse: 14-16 mm. 



Five cf cf from Paradise, Cochise Co., Ariz., June and August. 



Holotype cf, U.S. National Museum, type no. 61443, collected in 

 August. Of the four cf paratypes, two are labeled "Aug.," one "Aug. 

 16-23," and one "June." One paratype has been retained by the 

 author and the remaining type material has been returned to the U.S. 

 National Museum. 



Remarks. — This subspecies bears a very close resemblance to both 

 laticapitanus and heinrichi in regard to general appearance and genital 

 structure. However, it may be distinguished from the former by its 

 antennae, each segment of which bears only one complete ring of 

 scales, and it may be separated from both by the shape of the cucullus 

 of its harpe. This subspecies is named in honor of Dr. J. F. Gates 

 Clarke.
