EMIBTOPTEKA OF THE NEW WORLD ROSS 441 



SCHIZEMBIA GRANDIS, new species 



Plate 19, B ; Figures 67-69 



Male. — Color (in alcohol) : Pterothorax, abdomen, legs, wings, 

 head, palpi, and basal antennal segment dark chocolate brown; pro- 

 thorax reddish yellow ; antennal segments 2-14 tan, terminal segments 

 brown. Length 10 mm.; forewing length 8 mm.; breadth 1.8 mm. 



Head (fig. 67) small but larger than terminalia; sides behind eyes 

 straight, rather strongly convergent caudad, abruptly rounded and 

 somewhat transverse behind. Eyes moderately large, inflated ; inter- 

 space twice as wide as an eye width. Antennae with 23 segments 

 (probably complete). 



Wings (pi. 19, B) very large, broad. Kadius unusually narrow; 

 bordering bands very narrow^ pigment granules small, dull red. 

 Eadial sector forked within basal half of wing; R2+3 pigmented to 

 margin, R^+g pigmented at extreme base only. M and Cuia each 

 rejDresented only by a row of setae. Cuib narrow. Anal vein present 

 as a short basal rudiment, united by a cross vein to common base 

 of cubitus and media. Cross veins absent in remainder of wing except 

 for four between Ri and Ro^.. Color uniform dark brown; hyaline 

 stripes very narrow and sharply defined. 



Terminalia (figs. 68, 69) very small in relation to other body pro- 

 portions. Cleft of tenth tergite complete, very broad, membranous, 

 microreticulate in caudal half. Process of left hemitergite (10 LP) 

 broad, bearing a small hook at outer apical margin. Inner margin 

 of right hemitergite (10 R) irregular, deeply notched at apical third; 

 process (10 RP) complex. Ninth sternite (H) subquadrate, bearing 

 long setae; process (HP) nearly symmetrical, short, broadly rounded, 

 margined apically by an internal narrow flange, surface wrinkled. 

 Composite left paraproct and left cercus-basipodite (LPPT+LCB) 

 represented by a free, heavily sclerotized, narrow sclerite ; right para- 

 proct obsolete. Basal segment of left cercus (LCi) gradually inflated 

 terminally on inner side, bearing numerous echinulations. Basal seg- 

 ment of right cercus cylindrical.^ Terminal segments of both cerci 

 equal. 



Female. — No specimens definitely associated with a male. 



Holotype. — Winged male, on slide, U.S.N.M. No. 56044. 



Type data. — Collected in a shipment of Gattleya from Caracas, Ven- 

 ezuela, in plant quarantine at Washington, D. C, May 4, 1939 (In- 

 spectors Sanford and Adams). 



Othei' records. — Three males, all collected in wild Gattleya in plant 

 quarantine at Washington, D. C. — two of these in shipments from 



8 The inner surface of the basal segment of the right cercus of one of the available 

 specimens bears four distinct peglike echinulations, which are absent in the other speci- 

 mens at hand.
