(more or less dotted between the veins), which is broad above and nar- 

 rows below, and correspond to the light band in P. celtidis-mamnta. 

 The lower margin is black with hyaline interruptions, somewhat as in 

 P. celtidis-mamma. Hind wings milky-hyaline. Head dull, granular, 

 middle of front blackish, sides very broadly dull ochreous, a black dot 

 on each side of the middle; in the middle line, between the antennae, is 

 a dot of scarlet ; antennae with the first two joints thickened, the first 

 fuscous; la-st joint intense black; intermediate joints yellowish-white, 

 white dusty apices; thorax above dull or moderately shining, strongly 

 clouded with brown, with a fine median pale line; legs dull pale grayish- 

 ochreous, the femora slightly marked with darker. Length of anterior 

 wing about 2^4 mm. 



Galls crowded on underside of leaf of Celtis- reticulata Torrey; about 

 6 mm. diameter, elevated, mammiform, with a long nipple-like protu- 

 berance. 



Mr. S. A. Rohwer collected the galls at Boulder, Colorado 

 (where I have also found them), and bred the adults August 

 30, 1907. We both studied them at the time, but lacked some 

 of the necessary literature, which has been kindly supplied by 

 Dr. L. O. Howard. 



The only other Pachypsylla known from Boulder County 

 is P. celtidis-geimna, Riley, determined by Mr. Schwarz. The 

 single specimen was found by my wife squashed in a book bor- 

 rowed from the Boulder public library; it is therefore just pos- 

 sible that it did not come from Boulder. 



MR. HENRY H. LYMAN, of Montreal, Canada, has sent us a copy of 

 the "American Examiner" which contains an article on butterflies and 

 he says it is the biggest thing in Newspaper Entomology he has seen. 

 It begins as follows : "Within the past fifty years over a billion dollars 

 worth of butterflies have been caught by butterfly hunters and sold 

 to collectors. So extensive is this industry at the present time that 

 it may be safely asserted that over twenty million dollars a year are 

 spent on these beautiful insects." It then goes on to tell of species 

 worth from one hundred to a thousand dollars each. No wonder there 

 is a duty on insects in this country. In Canada the late Dr. James 

 Fletcher had the duty removed from specimens that were imported 

 for study by entomologists but we in the United States are not so 

 fortunate. We hope that members of Congress won't see the article 

 mentioned the next time the tariff is revised.
