NO.120S. NEW SPECIES OF TINEID MOTHS— BUSCK. 253 



on account of the following- newly discovered Florida species, wliicli 

 is an intermediate form. 



It has the antennae shorter than the forewing and has a slight indi- 

 cation of an eyecap; also in coloration it comes between the "red'' 

 inKignh and the "white" undoubted Phyllocnistis group, although it 

 is nearest to the former. 



PHYLLOCNISTIS INTERMEDIELLA, new species. 



Antennae nearh' as long as forewnng, silvery yellow, basal joint 

 slightly enlarged and flattened. Labial palpi silver}^ white, pointed, 

 drooping. Maxillary palpi obsolete. Head and thorax light silvery 

 gray, anterior wing, basal two-thirds silvery gray, somewhat lighter 

 than in P. insignis Frey and Boll, but not the pure white as in the 

 grape-feeding species. In the costal part of the wing, beginning at 

 base and reaching to the apical third of the wing is a sharply defined, 

 light-golden, spindle-shaped streak, nearest to the costal margin at 

 base of wing, nearest to the fold at apical third. 



The first part of apical third of the wing is evenly overlaid with 

 dark gray, then follows a large oval bright orange-colored black- 

 centered spot, and just at apex is a large deep black dot emitting into 

 the white cilia five black streaks, three into the costal and two into the 

 dorsal part. The cilia is very long, dorsal and costal part about equally 

 developed, and it has besides these five black streaks one more costal, 

 directed toward the base of wing, and in the dorsal part is a dark fus- 

 cous streak, parallel with the dorsal margin. Hindwing dark gray; 

 cilia 5, silvery white. Abdomen above dark fuscous, below silvery 

 white. Legs silvery white, last joint of tarsi black. Posterior tibiae 

 with long stifi' bristles above. 



Alar expanse, -1.2 mm. 



Tt/pe.—^o. 5189, U.S.N.M. 



Bred during early Februar}" from leaves of Mastic, Sideroxylon 

 {Mast icodendr 071) 'pallidum., collected by Dr. D3^ar, at Palm Beach, 

 Florida. 



The mine is on the underside and of the usual Phyllocnitis tvpe; 

 a long, whitish, irregular serpentine just below the epidermis, confined 

 to one side of the leaf, not crossing the main rib. Total linear length 

 of an average mine about 10 inches; ending at the edge of the leaf, 

 where a little pucker is made, the leaf slightly drawn, and the cocoon 

 formed within the mine. 



In a few cases mines were found on the upper side of the leaf.
