PSYCHE. 



[October 189S. 



gust 28, on flowers of Eriogonum jatnesii 

 Benth. (det. Tinsley) . 



Length, loj mm. (not incl. antennae). 

 Yellow stripe of cheeks not reaching 

 oral margin. Antennae light yellowish 

 red, except black arista. Yellow spots 

 of frontal triangle subobsolete, pile 

 black. Pile of thoracic dorsum black, 

 of pleura whitish, no yellow on sides 

 of dorsum nor in front of scutellum. 

 Fourth abdominal segment with no trace 

 of a band, wholly greenish black, 

 clothed with white pile. The reddish 

 yellow bands of second and third seg- 

 ments are well separated. Second and 

 third segments of venter yellowish. 

 Proximal half of tibiae yellowish, meta- 

 tarsi more or less reddish. 



This specimen can not be referred to 

 Williston's var. lentum, but may be 

 intermediate between lentum and the 

 normal form. 



8. Cuterebra nitida Qo(\. Two males, 

 Filmore Caiion, about 6,000 ft., Au- 

 gust 27, 1897. These specimens, and 

 others which were seen but not cap- 

 tured, were found flying up and down 

 the bed of the stream at the camp, and 

 alighting on rocks beside or between 

 the pools of running water. 



They agree with Coquillett's de- 

 scription, except that the two opaque 

 pollinose spots contiguous to the eyes 

 are not distinct, and the abdomen shows 

 faint suggestions of pollen in certain 

 lights at extreme base. 



9. Peleteria iterans Walk. Two 

 females. One on flowers of Chrysopsis 

 villosa Nutt. var., top of ridge above 



head of Filmore Caiion, about 8,500 ft., 

 August 28. The other, Filmore Caiion, 

 about 6,000 ft., August 27. 



This is the species which I have 

 always identified as Echinomyia (^Pelete- 

 ria) iterans Walk. According to Mr. 

 D. W. Coquillett's Revision of Tachini- 

 dae of America north of Mexico (Techn. 

 Bull. No. 7 Div. Ent. U. S. Dept. 

 Agric), this species would be known as 

 Peleteria tessellata Fab. From a lack 

 of evidence upholding the synonyms 

 given in this work, I am constrained to 

 continue to call this species P. iterans. 

 There are many reasons which make 

 the synonymy given by Mr. Coquillett 

 under Peleteria and Archyias extremely 

 doubtful. I have followed Williston's 

 conception of P. iterans Walk. (Trans. 

 Am. Ent. Soc. XIII, p. 301), in con- 

 sidering that it possessed the bristles 

 contiguous to lower portion of eyes ; 

 while in the above "Revision" iterans 

 Walk, is placed in Archytas in which 

 these bristles are absent, and is more- 

 over made a synonym of A. lateralis 

 Mcq. (formerly known 2.sjuritiia later- 

 alis) ! Further, we have only the 

 author's dictum that the present species 

 is the same as the European tessellata 

 Fab. ; while both Brauer and Bergen- 

 stamm and van der Wulp, w-ho ought to 

 know the European form, have consid- 

 ered the American different. This is only 

 one of the many examples of incongruity, 

 and lack of substantiating evidence for 

 statements made, to be found in Mr. 

 Coquillett's paper, to which I shall have 

 occasion to refer in detail at another time.
