because of the unarmed fore tibiae. The species was heretofore very 

 rare in collections, which helps to account for its misplacement. There 

 were only two specimens in the Barnes Collection and none in the U. S. 

 National and British Museums. Last season Mr. O. C. Poling sent 

 the authors nineteen specimens from the Baboquivari Mts., Pima Co., 

 Ariz., 15-30 Aug., and 1-15 Sept. 



OsLARiA Dyar. 



Type viridifera Grt. 



1904, Dyar, Jour. N. Y. Ent. Soc, XII, 41, viridifera sole species and 

 designated type. 



1910, Hampson, Cat. Lep. Phal. B. M., IX, 257, viridifera designated type. 



Hampson's diagnosis is in error in that viridifera possesses a 

 small spreading prothoracic crest ; and the tongue is not aborted, being 

 over twice the length of the eye. 



OSLARIA PURA B. & McD. 



1911, B. & McD., Can. Ent., XLIII, 319, Oslaria. 

 Seems to be a true Oslaria. 



Thurberiphaga Dyar. 



Type catalina Dyar. 



1920, Dyar, Ins. Insc. Menst., VII, 188, catalina sole species and therefore 

 type. 



Thurberiphaga diffusa Barnes. 



1904, Barnes, Can. Ent., XXXVI, 238, Alaria. 



1912, B. & McD., Contr. N. H. Lep. N. A., I, (4), 27, pi. XII, f. 1, Alaria. 

 1912, B. & McD., Contr. N. H. Lep. N. A., I, (4), 55, pi. XXVI, f. 3, 



"Alaria", "near Nocloa". 

 1917, B. & McD., Check List, p. 72, No. 2781, Oslaria. 

 1923, Dyar, Ins. Insc. Menst., XI, 18, Thurberiphaga. 



catalina Dyar. 



1920, Dyar. Ins. Insc. Menst., VII, 188, Thurberiphaga. 

 1923, Dyar. Ins. Insc. Menst., XI, 18, diffusa, Thurberiphaga. 



Dr. Dyar (1923) is correct; a specimen agreeing with the type 

 of catalina (compared by Mr. Schaus) also agrees with the type of 

 diffusa. 



Perfect specimens agree with the genotype of Oslaria, viridifera, 

 in possessing a small spreading thoracic crest and a divided metathor-
