NORTH AMERICAN ACROLOPHIDAE — HASBROUCK 567 



this group under Acrolophus, and the combination, Acrolophus con- 

 jusellus Beutenmiiller, is not Hsted in the Zoological Record between 

 the years 1891, when it first appeared in Smith's checklist, and 1886, 

 when Beutenmiiller's name first appeared as an author in the Zoologi- 

 cal Record. 



It is fau-ly obvious from Dyar's "description" of confusellus that 

 it is simply a specimen of popeanellus. The type <f, at the U.S. 

 National Museum, where I was able to examine it, is labeled "Acro- 

 lophus conrfusella (Beut.) Dyar, type no. 405, Georgia, Beutenmueller 

 Collection." The genitalia, removed and mounted on a shde by 

 Busck on Oct. 12, 1933, confu-m the identity of confuselliLS with popea- 

 nellus, and this is further confirmed by several slides of d^ genitalia of 

 "cotypes" of confusellus that also proved to be popeanellus. Thus, 

 confusellus (Dyar) should be considered a new synonym of popeanellus 

 (Clemens), Dyar having changed his original and correct placement. 



12. Acrolophus acanthogonus Meyrick, incertae sedis 



Acrolophus acanthogona Meyrick, 1919, Exotic Microlep., vol. 2, no. 9, p. 279, 

 Nov. — McDunnough, 1939, Check List Lep. Can. & U.S. Amer., p. 103, no. 

 9571. 



Meyrick's original description follows: 



Acrolophus acanthogona — cf . 28 mm. Head, palpi, thorax fuscous; structure of 

 palpi and antennae quite as in popeanella. Abdomen light fuscous; genitalia 

 similar to popeanella, but angle of uncus furnished with a strong acute-triangular 

 projection, points appressed together throughout, valvae with apex broad, slightly 

 rounded. Forewings elongate, posteriorly somewhat dilated, costa gently arched, 

 apex rounded-obtuse, termen rounded, somewhat oblique; fuscous, irregularly 

 sprinkled dark fuscous; some indistinct small cloudy dark fuscous strigulae along 

 costa; some slight whitish suffusion on fold, and two or three dark fuscous strigulae 

 beneath it towards base; submedian and postmedian spots indicated by some irreg- 

 ular dark fuscous irroration; one or two small indistinct spots of dark fuscous 

 irroration towards termen above middle; a terminal series of small mdistinct spots 

 of dark fuscous irroration : cilia fuscous (imperfect) . Hindwings dark grey, rather 

 lighter anteriorly; cilia greyish, a darker subbasal shade. 



Texas; one specimen. Nearly allied to popeanella, but forewings slightly broad- 

 er posteriorly, more uniformly coloured, and easily distinguished by genitalia. 



This species, based on a single cf specimen from Texas, is treated 

 here as incertae sedis, since no specimen is available for study. The 

 name should be spelled acanthogonus to agree grammatically with its 

 genus, Acrolophus. Mr. Tams of the British Museum (Natural His- 

 tor}^, where the type is located, originally sent photographs of both 

 this moth and its genitalia. Later, when Dr. J. F. Gates Clarke of the 

 U.S. National Museum studied Meyrick's types at the British Museum 

 (Natiu-al HistorjO, the genitalia of acan^A 0/7071 ws were remounted and 

 again photographed in clearer detail. Dr. Clarke loaned two photo- 

 gi-aphs of acanthogonus, one showing the genitalia in ventral aspect,
