FAMILY XV. — TINGIDIDjE. 



the wild olive, Osmanthus americanus (L.). Known only from 

 Florida. In this species the elytra are distinctly less widened 

 at middle than in the two preceding, with costal margin very 

 narrow, thus approaching mutica. 



475 (666). Leptoypha mutica (Say), 1832, 27; I, 349. 



Elongate, subparallel. Dark reddish-brown, the head and apical 

 third of pronotum often with a whitish bloom ; thorax with elevations 



behind collar, and often some blotches on disk, 

 fuscous; elytra with veins of membrane and 

 a vague submedian cross-bar fuscous; collar 

 and buccuke dull yellow; antenna? and legs 

 fuscous, the apical portions paler. Antennas 

 much shorter than in preceding species, the 

 third joint scarcely twice as long as first and 

 second united. Pronotum with median third 

 strongly convex; median carina percurrent, 

 traces of the others often visible on posterior 

 « -*"*! , : r 2%^^ third. Elytra but very slightly widened at 



3T*^ middle, the costal margins visible only on 

 apical half. Other characters as in key. 

 Length, 2.7—2.9 mm. (Fig. 121). 



Marshall, Marion and Crawford coun- 

 ties, Ind., June 13 — Oct. 13. Swept 

 from foliage of ash. Ranges from 

 Quebec and New England west to 

 North Dakota and Nebraska, and south 

 to Georgia, Florida and Texas. Known 

 as the fringe tree lace bug and occurs 

 on ash and the fringe tree, Chionanthus virginica L. Varies much 

 in color, some specimens being almost black. Hussey reports 

 it as rather common in southern Michigan on the seedlings of 

 the white ash, Fraxinus americana L., "occurring only on the 

 upper side of the leaves near the midrib." The only Florida 

 record is that of Drake (1918b, 88) without definite station. 



476 ( — ). Leptophya ilicis Drake, 1919, 420. 



Narrowly oblong, subparallel, constricted near base and apex of 

 elytra. Pale to dark reddish-brown, often with small scattered fuscous 

 areas; collar and apex of postmedian process of pronotum sometimes 

 paler; apex of discoidal area and veins of membrane in part fuscous; 

 tarsi fuscous. Antenna? short, stout, cylindrical, joints 1 and 2 sub- 

 equal, united slightly longer than 4, 3 equal to all the others united. 

 Pronotum with median portion very strongly convex, median carina dis- 

 tinct, lateral ones wholly obsolete. Costal area of elytra with only a few
