NORTH AMERICAN ACROLOPHIDAE — HASBROUCK 627 



W. S. Wright on the following dates: June 19 and 22, 1909; June 30, 

 July 1, 3, 24, 30, and August 21, 1911; July 3 (two specimens), 1913. 

 Busck described leopardus immediately after occidens in the same 

 article. As it has been shown above, the two are not sufficiently dis- 

 tinct to be considered as separate species. Thus, since leopardus occurs 

 in the same area as occidens, it should be considered as a form of the 

 latter, rather than a direct subspecies of laticapitanus. Contrary to 

 Busck's comment, a comparison of the genitalia indicates that leopar- 

 dus is not especially closely related to Acrolophus puncteUus (Busck), 



30d. Acrolophus laticapitanus heinrichif new subspecies 



Figure 148 



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

 from head and from each other distad. Eyes large, protruding, with- 

 out setae or lashes. Antennae simple; segments robust, subglobose, 

 each furnished %vith one complete ring of ochreous scales. Head, 

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

 minute, fuscous spots scattered in apical third. Hindwings and abdo- 

 men fuscous. Genitalia as in laticapitanus except for cucullus of 

 harpe (fig. 148); cucullus somewhat variable but distinctive, only 

 sHghtly constricted at base, major portion sublinear and rather slender, 

 dorsal and ventral margins weakly sinuate and subparallel, apex sub- 

 truncate and with dorsal portion developed slightly to considerably 

 further distad than ventral portion. Expanse: 17-18 mm. 



Female. — Labial palpi ochreous, slightly shorter than in cf, 

 porrect, closely subparallel. Elyes similar to those of cf , but slightly 

 smaller. Antennae simple; segments more elongate and slender than 

 those of cf, each almost completely covered by ring of scales. Colora- 

 tion of head, thorax, wings, and abdomen same as in cf. Expanse: 

 20-22 mm. 



Holotype cf, allotype 9, paratype cT and 9, U.S. National 

 Museum, type no. 61442, all from Baboquivari Mountains, Pima 

 County, Ariz. The holotype cf is labeled "Aug." The allotype 9 

 has nine, variously sized, pale orange mites attached to its abdomen. 

 In the paratype cf , the labial palpi are very widely divergent and 

 partially cover the eyes. These four specimens were found in the 

 laticapitanus series at the U.S. National Museum. I am also desig- 

 nating as paratypes of heinrichi three cf cf received on loan from the 

 American Museum of Natural History through the com'tesy of Dr. 

 Alexander B. Klots. These were collected by Dr. Klots at Boyce 

 Thompson Arboretum, Superior, Pinal Co., Ariz., August 1-2, 1937. 

 Dr. Klots' specimens agree remarkably well with Dyar's original 

 description of unistriganus from Williams and FlagstaflF, Coconino
