NO. 1208. NEW SPECIES OF TINEID MOTHS— BUSCK. 229 



NEALYDA PISONI.^, new species. 



(Plate I, fig. 5.) 



Antenna? nearl}" |, simple, brown with black annulations. Labial 

 palpi second joint fu.scous, white at apex, teiminal joint black with a 

 white annulation around middle. Maxillary palpi obsolete. Face, 

 head and thorax bright golden brown. Anterior wing very thickly 

 scaled; ground color concolorous with thorax, bright golden brown; 

 one-third from base is a dark, rich, velvety brown, broad fascia, 

 sharply defined on both sides, darkest, nearly black, and somewhat 

 broader at the dor.sal edge, where it terminates in slightly raised scales, 

 projecting outside the edge of wing in a dorsal tooth, and forming in 

 the living insect at rest a curious hump on the back. This fascia is 

 still more thickh^ scaled than the rest of wing. A little more than the 

 apical third of wing is densely dusted with black scales, which con- 

 dense into four, all black, velvety spots, one large costal spot, one- 

 third from apex reaching down to fold, one smaller apical, one moon- 

 shaped at tornus, and a small round dot between the two latter. The 

 last three are internally edged by light silvery scales forming an indis- 

 tinct, thin, open V, with the point toward apex. Cilia very heav}^ and 

 cut olf nearly perpendicular, giving the wing the appearance of being 

 very ))road. This, together with the robust body, gives the moth a cer- 

 tain resemblance to a Tortricid. Hindwings bilobed, three-fifths as 

 wide as forewings, purplish grey with silvery reflections; cilia lighter. 

 Abdomen dark purple with metallic reflections. Legs and underside 

 of thorax straw-yellow with sparse ]:)urple scales intermixed; tarsi 

 black with yellow annulations. Posterior tibite with long 3'ellow hairs 

 above. 



Alar expanse: male, 7 mm,; female, 8.2 mm. 



Descri)>ed from 2 specimens, reared February 2 and Februarj' 18, 

 1900, from mines on Plson'm aculeata., collected by Dr. Dyar at Palm 

 Bea(-h, Florida. 



Type.—^o. 4935, U.S.N.M. 



Egg is laid at the midi'il) on the upper side of the leaf and the mine 

 is a more or less irregular, large, trumpet-formod l)lotch on the upper 

 surface with the black frass s(;attered in the middle of the mine. The 

 larva is, when full grown, cylindrical, somewhat flattened, strongly 

 segmented, and tapering l)ackward, about 7 mm. long. It has three 

 pairs of normal thoracic feet, four pairs of abdominal feet suggesting 

 the toes of a tree frog, being very long and thin with a globular 

 swelling at the end; while in the mine they are pointed ))ackward, flat 

 to the body; no anal legs. Larva is white with light-brown head and 

 thoracic plate; sutures in head darker brown. When mature it cuts 

 its way out of the mine and spins nearby on the leaf a tough, oval, 

 flat, white cocoon, from which the pupa does not protrude, when
