following year two species, H. phthisica and jyrasina, were described 

 by Saussure and Pictet."^ 



In 1900, Scudder described H. elegans^'^ and but little later in the 

 same year Arethaea consuetipes,-^ which latter species we have found 

 through previous examination of the type and present study of the 

 paratype to be a geographic race of /. elegans. Scudder referred 

 this species to Arethaea through failure to compare his material 

 with I. elegans, apparently basing his decision solely on Brunner's 

 incorrect key character regarding the presence or absence of styles 

 on the male subgenital plate as separating Insara (Hormilia) from 

 Arethaea. 



Rehn, in 1907, described a single species as H. apache}^ 



Material Examined. — 239; 124 males, 99 females, 1 gynandro- 

 morph and 15 nymphs. 



Nearly half of these specimens (111) were taken by the authors 

 on recent trips and are located in the Hebard Collection and that of 

 the Academy of Natural Sciences of Philadelphia. Of the remain- 

 ing specimens we find 65 in the Hebard Collection; 33 in the Acad- 

 emy of Natural Sciences of Philadelphia and 12, the entire series 

 of the genus in the United States National IMuseum, were loaned 

 to us through the kindness of Mr. A. N. Caudell. The remaining 

 18 specimens we have been able to examine through the kindness 

 of the authorities in charge of the British Museum, Scudder Col- 

 lection, American Museum of Natural History, Brooklyn Insti- 

 tute of Arts and Sciences, and the University of Kansas. To those 

 who have so kindly assisted us we wish to express our hearty 

 thanks. 



In the preparation of the present paper the t3^{)es of the follow- 

 ing species have been examined by us.
