3.04 mm, width of abdomen 3.92 mm. 
Houoryrpr.—Male, collected in Hoboken, New Jersey, on Orchids

Remarks.—Mezira crenulata, in my key (1960, p. 260) for American 
Mezira species runs to M. mexicana Kormilev but looks more lke 
M. boliviana Kormilev from which it differs by spiracles VIII sub- 
lateral and not visible from above (lateral and visible in M. boliviana); 
head as long as wide; lateral borders of pronotum distinctly crenu- 
late; hypopygium different: its upper surface produced as far as 
its lower portion (in M. boliviana the upper portion is distinctly 
shorter than its lower portion).

ments I to IV: 10:9:11:10; pronotum 21:51; scutellum 19.5:28; 
abdomen 80:58 across segment V; hemelytra reaching to foreborder 
of tergum VII; hypopygium 20:24. 
Total length 6.0 mm, width of pronotum 2.04 mm, width of abdomen 
2.32 mm. 
Hotoryrr.—Male, Hugural Rd., Puerto Rico, J. R. Johnston,

ParatyPes.—T'wo males and four nymphs of different instars, 
collected with holotype; in the same collection and collection of the

Remarks.—This species is based on a series of specimens from 
Puerto Rico and one series from Haiti. The Puerto Rico series has 
one specimen with a label ‘‘Mezira n.sp., det. H. G. Barber,” and the
