NO. 1208. :^E W SPECIES OF TIN EI D MO TIIS—B USCK. '245 



Venation. — Fore winj^s: veins, 3 and 4 absent, (> and 7 stalked, 

 7 to costa, 11 absent, 1 simple. Hind wing-s: 4 veins, 7 to apex, 6 out 

 of 7; median s^^stem represented by a single vein. Cilia 5. 



Position at rest more like Tisheria than Gracilaria, body obliquely 

 raised in front and forelegs applied to l)od3^ Antenna? are laid alontr 

 and over the forewings. Before settling down to rest th(», moth whirls 

 the antennas in rotary motion and raises the body up and down with 

 an impatient motion, alternately bending and stretching forelegs. 

 The genus is allied to Ornix, but reminds one much of Tisheria and 

 Bedell ia. 



METRIOCHROA PSYCHOTRIELLA, new species. 



(Plate I, fig. 13.) 



Antennse bluish black annulated with white, last joint white. Labial 

 palpi light yellow, with a ring around the middle of terminal joint 

 l)lack. Maxillary palpi white. Face white, vertex white with 1)luish 

 scales intermixed; sides of head, thorax, and anterior wings dark 

 brown, nearly black, with a bluish metallic ].uster and with sparse 

 l)luish-Avhite scales uniformly intermixed. Cilia dark gray with two 

 apical transverse lines black. Hindwings light purplish grey, cilia 

 darker. Abdomen of the general hue, with the anterior margin of 

 each segment light yellow. Legs yellow; tarsi annulated with bluish 

 black. 



Alar expanse, 5.5 to 5.8 mm. 



Described from six specimens bred from mines on PHijchotria 'undata^ 

 collected by Dr. Dyar at Palm Beach, Florida. 



Type.^'^o. 4955, U.S.N.M. 



Egg is laid on upper surface of the leaf; mine is a long (15 mm.), 

 winding, narrow serpentine on upper side of leaf, with the black 

 f rass deposited in quite regular transverse lines. Gradually it becomes 

 broader (2 to 3 mm.) and ends in a small, oblong (5 to 6 mm.), broad 

 blotch, drawn together longitudinally into one or more ridges, beneath 

 which the larva pupates without forming any cocoon, the mine being- 

 simply slightly silk lined. The pupa protrudes when the moth issues. 



Larva is most singular; cylindrical, soyiewhat flattened, with no 

 trace of thoracic feet; in their place three pairs of polished circular 

 plates; five pairs of well-developed abdominal feet, one pair on each 

 of joints 6, 7, 8, 9, 10, counting the head as first joint; no anal feet. 



MARMARA Clemens. 



MARMARA GUILANDINELLA, new species. 



Antennae f , rather thick, with large pecten beneath basal joint, and 

 sparsely ciliated throughout; metalli(! ])lack. Lalfial palpi slightly 

 curved, in the living insect reaching vertex, in dead specimens por-
