EMBIOPTERA OF THE NEW WORLD — ROSS 487 



orange; 10 LP yellow. Length 7.5 mm.; forewing length 5.0 mm., 

 breadth 1.2 mm. 



Head (fig. 148) elongate, with eyes relatively small, not strongly 

 inflated, separated by interspace equal to two and one-half eye widths : 

 sides behind eyes two eye lengths long, scarcely convergent, subparal- 

 lel, feebly arcuate ; caudal margin abrupt, arcuate medially. Mandi- 

 bles with apical teeth broad, blunt; inner medial angles very sharp, 

 prominent. 



Wings well pigmented ; with four cross veins present between R^ and 

 R2+3 in forewing and seven between Ri and costal margin; R2+,'!, the 

 only pigmented vein behind R^, nearly attaining terminus. Hind- 

 wing with two cross veins between Ri and R2+3 and five between R2+3 

 and costal margin. Ri very closely paralleling costa in both wings. 

 Hyaline lines sharply defined, nearly equal in width throughout both 

 wings. 



Terminalia (figs. 149, 150) similar to giganfea but darker, with basal 

 projection of tenth tergite more acute and extending partially beneath 

 eighth tergite; left tergal process (10 LP) broader and with minor 

 differences in form; right tergal process (10 RPi) narrower, longer 

 and more sharply pointed apically. Process of hypandrium (HP) 

 and left paraproct (LPPT) longer and narrower, the latter longer 

 than HP rather than subequal as in gigantea. Left cercus-basipodite 

 (LCB) with ventral inner lobe narrower, shape irregular; dorsal lobe 

 with "claws" distinctly separated, its basal lobe large, but not clearly 

 delimited. Inner margin of basal segment of left cercus (LCi) more 

 deeply emarginated, apical inner lobe acute. Inner margin of right 

 cercus also more deeply emarginated, 



Femule. — Unknown .
