but having the inner portion yellowish-brown and the outer pale. Then comes a 

 pale greyish area, and then a third band, the zigzag band seen in other members of 

 the genus ; this is yellowish-brown, bordered with whitish internally, and having a 

 broader but somewhat indistinct grey external border. Between this and the outer 

 margin is a greyish-brown area. On the outer margin are eight dark grey spots, the 

 first three being enclosed in the dark area of the upper part of the wing, and the 

 last two being almost obsolete. Fringe pale greyish-brown. 



Secondaries plumbeous-grey, slightly lutescent. Eyes grey. Palpi, head and 

 thorax yellowish-grey. Abdomen grey, with the lower border of each segment pale 

 yellowish-brown. 



Under-side of wings pale grey, with a brownish tinge on the costal margin of 

 primaries. Legs pale yollowish-grey. 



Hal. : near Ula, Custer Co., Colorado, U. S. A., 1887. 



Among the other Lepidopterous captures of the past year are a 

 probably new Alucita, and undetermined species of Agrotis, Gidnria, 

 and Eupitliecia, as well as several interesting known forms. On 

 August 4th I took Nomopliila noctuella in Cottonwood Gulch, Saguache 

 Co., adding another locality for this cosmopolitan insect. 



The Chrysomelid beetle mentioned in connection with a case of 

 mimicry on p. 214, has been submitted to Prof. C. V. Eiley, and proves 

 to be Disonycha punctigera, Le Conte.

Cecidomyia nigra, Meigen. — For some years past my Marie Louise pears have 

 been much infested by Dipterous larvse, which destroyed a great portion of the crop 

 soon after the pears had set. On sending some of the little infested pears to 

 Mr. E. Fitch, he informed me that they were inhabited by the larva; of C. nigra, Mg., 

 but that they had not been reared of late years, and that it was not known to which 

 division of the genus Cecidomyia the insect belonged. The next year, 1886, I sent 

 a supply of the pears to Mr. P. Inchbald, of Fulwith Grange, who is usually very 

 successful in rearing Cecids and other Dipterous parasites. These infested pears are 

 mentioned by him, Ent., Feb., 1887, p. 35, but he did not rear a single specimen the 

 following spring. I therefore, last June, sent specimens to Mr. Inchbald, Dr. Meade, 

 Mr. E. Fitch, and Miss Ormerod, hoping that one or more would be able io rear 

 them. We had been much perplexed by Mr. Inchbald having reared a number of a 

 species of Sciara and no Cecidomyia, and began to think that the larvre must be a 

 Sciara. But Miss Ormerod, on seeing the little larvae, at once gave her opinion that 

 they were undoubtedly the larvse of a Cecidomyia. Seeing Mr. Inchbald's notice in the 

 Entomologist, Professor Kiley wrote to him from Washington and expressed a great 

 interest in the subject, since a pear orchard in America had been suffering from what 

 he had every reason to believe was the same insect. He also sent the " Report of 

 the Entomologist for 1885," in which the insect is carefully described and figured in 

 the larva, pupa and imago states. I therefore sent some of the pears infested with 

 these larvce to America, which the Professor found agreed mobt closely with those
