aedeagi could possibly be used as an argument for placing pseudohir- 

 sutus as a subspecies of kearfotti, a situation discussed in my remarks 

 on the latter species. However, the two are retained here as distinct 

 species. The characters furnished by the cucuUus of the harpe in 

 pseudohirsutus are both distinctive and consistent tliroughout my 

 rather small series of this insect. The name, pseudohirsutus, has been 

 coined from the Greek word, pseudes, meaning "false," applied as a 

 prefix to Busck's old name, hirsutus. 



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

 It is labeled ^'Acrolophus hirsutus Busck, type no. 15123, La Puerta 

 Valley, Calif., July 1911, Geo. H. Field." The specimen readily 

 confirms the identity of this species. 



A. hirsutus, described by Busck in 1912, is still a valid species 

 although its name is preoccupied and must be replaced. 



In his revision of 1887, Walsingham erected a new genus, Thysanos- 

 celis, designating as its genotype the new species, T. hirsutus, from 

 Espirito Santo, Brazil. Following his description of hirsutus, Wal- 

 singham stated: 



I have two males of this curious species, purchased of Deyrolle in Paris many 

 years ago. They obviously belong to the same group as Acrolophus, Anaphora, 

 etc., but cannot, so far as I can determine, be rightly included in any hitherto 

 described genus. 



About the time Busck described his hirsutus from California, a 

 general agreement was developing among the several active describers 

 of acrolophids that most of the genera of the group should be combined 

 and placed under the original genus, Acrolophus. Several years later, 

 Walsingham (1915, pp. 375-380) found it necessary to place most of 

 his previously described genera, including Thysanoscelis , into synon- 

 omy under Acrolophus. Thus, Thysanoscelis hirsutus became Acrol- 

 ophus hirsutus (Walsingham), with the latter preoccupying Acrolophus 

 hirsutus Busck. 



Therefore, hirsutus Busck should be considered a new synonym of 

 pseudohirsutus, the new name here proposed to replace Busck's pre- 

 occupied species name.
