apical dot. The last of these meets a similar black streak pro- 

 jecting into the cilia below the apex The oblique triangular 

 costal streak meets in the middle of the wing the apex of a grayish 

 V-shaped mark placed at the tornus. The space between the arrrs 

 of this mark is sometimes suffused with gray. A yellow patch 

 occupies the apex of the wing and is margined along the termen 

 by blackish scales. A black streak projecting out into the apical 

 cilia from the apical dot is crossed at right angles by a nearly 

 straight black line. Hind wings and cilia gray. 



Abdomen gray, white beneath. Legs whitish, tarsal segments 

 tipped with black. 



Expanse: 9-10.5 mm. 



Three specimens, Santa Cruz Big Trees, Calif., the larva? 

 mining leaves of Azalea, Rhododendron occidentale Gray, July 21; 

 one specimen, Mt. Rainier, Wash., mining leaves of the white 

 Rhododendron, Rhododendrojt alhiflorum Hook., August 15. The 

 imagos appeared August 4-7 and August 28. 



The early long very narrow linear mine (3-4.5 mm.) abruptly 

 enlarges into an irregular blotch. The pupa is enclosed in a slight 

 white cocoon. 



This species is nearest to L. latistrigella Wlsm., also a Rhodo- 

 dendron miner; but differs strikingly from it in the absence of the 

 conspicuous curved black streak from the middle of the dorsum.

 Notes on Some Miscellaneous Economic Insects Found in 



New Jersey. 

 Callopistria floridensis Guen. (Lep.). This insect, known as 

 the Florida Fern-Cutworm, which has already been recorded by 

 me as occurring in New Jersey (Canad, Ent., Jan. 1915), and 

 doing considerable damage to ferns in greenhouses, was found to 

 be effectively controlled by spraying with fresh pyrethrum, one 

 ounce to one gallon of water, plus one half ounce of soap. One 

 large fern grower in New Jersey applied the above spray once a 

 week for five or six weeks and gained complete relief. Pyrethrum 

 was also applied with a bellows, and similar results obtained. 

 Mf. J. J. Davis, in the 27th Report of the State Entomologist of 

 Illinois, advocates the use of this material, which is undoubtedly 

 the best insecticide to use against this pest.
