498 FAMILY XV. — TINGIDID^E. 



Known elsewhere only from New Orleans, La., where it was 

 taken from camphor trees. 



X. Leptoypha Stal, 1878, 121. 



Small elongate-oval or subparallel species having the sternal 

 sulcus closed in front, uninterrupted behind; hood wanting; 

 head with short tubercles or obtuse spines ; antennae short, 

 cylindrical, the two basal joints short, subequal, the third 

 longer than the others united ; margins of paranota, and often 

 the costal margin, not flattened or reflexed ; pronotal carina 

 single, usually with traces of the other two; tip of pronotum 

 acute ; elytra surpassing abdomen, their discoidal areas slightly 

 elevated above the costal ones, reaching to or slightly beyond 

 middle, bounded by acute carina-like margins. Five of the six 

 known North American species occur in the eastern states. 



KEY TO EASTERN SPECIES OF LEPTOYPHA. 



a. Costal margin of elytra flattened and reflexed, distinct for its whole 

 length ; elytra widest across discoidal area, than narrowed to- 

 ward apex. 

 b. Costal margin with two rows of areolae throughout part of its 

 length. 

 c. The two rows of areolae present only on basal third; third anten- 

 nal slightly less than twice as long as 1 and 2 united. 



472. COSTATA. 



cc. The two rows of areola? extending to apical fourth ; third antennal 

 more than three times as long as 1 and 2 united. 



473. ELLIPTICA. 

 bb. Costal margin with a single row of areola? throughout its length. 



474. MCATEEI. 



aa. Costal margin not flattened but very narrow and deflexed, replaced 



by subcostal margin along basal third; elytra subparallel, but 



little widened across discoidal area. 



d. Larger, length more than 2.5 mm. ; third joint of antenna? nearly 



four times as long as basal joint. 475. mutica. 



dd. Smaller, length not over 2.2 mm.; third joint of antenna? less than 



three times as long as first. 476. ilicis. 



472 (666%). Leptophya costata Parshley, 1917b, 16. 



Elongate-oval, widest at middle of elytra. Above dull brownish- 

 yellow, the antenna? and legs concolorous ; callosities of front lobe of 

 pronotum, some irregular lines on discoidal area of corium and veins of 

 of membrane, fuscous ; carina? on apical fourth of pronotum sometimes 

 whitish; under surface chestnut-brown. Head with two long, appressed 

 yellowish spines. First and second antennals subequal in length, united 

 about half as long as third; fourth nearly twice longer than first. Prono- 

 tum with median portion strong';/ convex, twice as wide as apical margin;
