NORTH AMERICAN ACROLOPHIDAE — HASBROUCK 599 



Source of material. — American Museum of Natural History 

 (3 cTcf, 1 9). 

 Specimens examined. — 4 (3 d^cf, 1 9), from 2 localities: 



Florida: Lake Placid, ? (Archbold Biological Station, July 1&-31, 1948, 

 A. B. Klots); Winter Park, cf (June 1946, A. B. Klots), & (July 1946, Klots), 

 cf (Sept. 1946, Klots). 



Remarks. — This species undoubtedly ranges southward and west- 

 ward into Alexico and is closely related to vanduzeei, the two com- 

 prising a small species group. The piger-vanduzeei species group 

 consists of small moths having shortened labial palpi, eyes rather 

 densely clothed mth erect setae, simple antennae with segments 

 encircled by rings of large scales, bifid uncus, and paired gnathos. 

 The vesica of the aedeagus is armed with cornuti in these two species. 

 A. piger may be distinguished from its close relative, as well as from 

 all the other species treated here, by its characteristic harpe and 

 aedeagus. In the latter structure, the armature of the vesica is quite 

 distinctive for this species. Although piger superficially resembles 

 forbesi in general habitus, the two are not closely related. 



I have examined the type cf specimen at the U.S. National Museum. 

 It is labeled "Ortholophus piger Dyar, type no. 5348, San Diego, 

 Texas, May 26, 1895, Coll. E. A. Schwarz." Dr. Clarke removed the 

 genitaha of the type for me and the identity of this species was thus 

 further confu-med. 



It is interesting to note that Dyar's type series of three cf specimens 

 representing piger actually represents thi-ee entirely different species. 

 The first specimen, set aside as the holotype or "type," properly repre- 

 sents piger as a valid species. The second specimen, set aside as a 

 paratype or "cotype," is equivalent to my new species, vanduzeei. 

 The third specimen, also designated as a paratype or "cotype," repre- 

 sents a third but already described species.

Male. — Similar to piger in general habitus. Head luteous suffused 

 with white. Labial palpi intermediate in length, recurved back over 

 head and extending to anterior margin of thorax, weakly to strongly 

 diverging from each other distad, moderately diverging from head dis- 

 tad, inner surfaces luteous but heavily fringed with white, outer sur- 

 faces ochreous suffused with fuscous, apical segments fuscous fringed 

 with white. Eyes large, protruding, weakly lashed; rather densely 

 clothed with short, erect setae. Antennae simple, luteous, each seg- 

 ment completely encircled by ring of large scales. Thorax luteous 

 suffused with white. Forewings ashy-gray marked with brown and
