the Mexican line runs, and I believe that this will be the southern record 

 of this species in our fauna for all time. Lceta has been recorded from 

 Mt. Graham, in Graham County, and has also been found in the 

 Chiricahua Mountains. It doubtless occurs in all the ranges of Southern 

 Arizona. Though it is well distributed, ranging from Quebec south to 

 West Virginia, and west to Montana, from whence it comes south to 

 Sonera, it seems to be everywhere local and scarce. Arizona Theclas 

 have been very much not in evidence this year. The first broods of 

 bienina Hewitson, iceta Edwards and spinetoriiin Boisduval have been 

 unduly scanty. Apama Edwards and tiielituis Hubner, however, were 

 quite common. Of hies Edwards, usually an abundant species, I have 

 only taken four or five examples. But two specimens of halesiis have 

 been seen, both in the Santa Rita Mountain?. Dr. Holland (Butt. Book, 

 p. 239) states that the larva of halesus is said to feed on various oaks. 

 The food-plant, however, is mistletoe, upon which I have found eggs. 

 T. crysalus Edwards has not appeared as yet (July). I can see no need 

 of retaining r//mrt! Hy. Edwards in our catalogues as a variety oi crysalus, 

 since it is only an individual variant. What Mr. W. G. Wright, in his 

 Butterflies of the West Coast, PI. XXVII, figs. 322, b and c, figures as T. 

 spi7ietorum is certainly not that species, but one of the Incisaiias, a group 

 that badly needs thorough revising. T. chalcis Behr. seems to be a pure 

 synonym oi scepium Boisduval. — [Karl R. Coolidge, Pasadena, Cal. 



CORRECTIONS TO MY PAPER ON THE TYPE-SPECIES OF 

 THE NORTH AMERICAN GENERA OF DIPTERA. 



BY D. W. COQUILLETT, WASHINGTON, D. C. 



The paper referred to in the above heading was submitted for publi- 

 cation on May 11, 1909. During the long interval that elapsed before its 

 publication on August 4, 19 10, several articles bearing more or less on 

 this subject appeared in print, necessitating several changes. Some of 

 these, of minor importance, were made in the proof-sheets, but others were 

 too extended to permit of being incorporated in this manner. These and 

 a few others to which my attention has been called, are brought together 

 in the following notes. I desire to express my thanks to Messrs. C. W. 

 Johnson and O. A. Johannsen for calling my attention to several of these 

 errors and omissions.
