THE LEAF BUGS. 663 



reaching the front angles; joint 1 of tarsi much longer than 

 and equal in thickness to joint 2; tarsal segments scarcely over- 

 lapping at joints and thus very flexible (straw climbers). 



Subfamily I. Miring, p. 665. 

 cc. Pronotum constricted near apex to form a distinct collar, the con- 

 striction sometimes interrupted above, but always extending 

 over the sides; lateral margins of pronotum frequently carinate, 

 but the carina? never reaching the front angles; joint 1 of tarsi 

 short, rarely longer than joint 2, if longer (Tribe Resthenini) 

 then much thicker than 2; tarsal segments with tips overlapping 

 the joints, thus practically inflexible (leaf walkers). 



Subfamily II. Capsin^e, p. 681. 

 bb. Arolia not divergent or divaricate, but converging toward tips 

 (figs. 33 — 54) ; pronotum without a collar. 



Subfamily III. Orthotylin^e, p. 796. 

 («. Arolia absent, or present but bristle-like in form (figs. 25 — 32) ; 

 sometimes difficult to distinguish from hairs on the tarsus. 

 d. Last tarsal joint swollen, always thicker than the one preceding 

 (fig. 22) ; tibiae destitute of spines; lorse confluent with the gena?; 

 pseudarolia very large, united to the claws along their inner 

 curve (figs. 22 — 24). Subfamily IV. Bryocorin.-e, p. 866. 



dd. Last tarsal joint slender; tibia? usually finely but distinctly spinose; 

 lora? usually distinct from genas; pseudarolia not as above. 

 e. Pronotum with apical third convex, rounded in front and pro- 

 longed forward as a hood-like projection above the base of the 

 vertex; stricture of the usual collar visible only at the sides 

 from which an impressed line extends inward to behind the 

 calli. Subfamily V. Clivinemin..e, p. 876. 



ee. Pronotum without an apical hood above the base of vertex. 



/. Pronotum constricted near apex to form a collar, this some- 

 times vague above at middle, but distinct on sides. 

 g. Tarsal claws simple and slender, rarely widely spread (figs. 25, 

 26) ; tibia? weakly spinose, usually long and tapering apically, 

 sometimes greatly shortened in which case the basal joint 

 of tarsi is unusually long, the head ti'ansverse and eyes 

 strongly protruding. Subfamily VI. Cylapin.e, p. 876. 



gg. Tarsal claws thick, either sharply bent (fig. 21) or broadly 

 curved (fig. 27), or more sharply curved and cleft or lobed 

 within near base (figs. 28 — 32). 

 h. Body not elongated; claws usually cleft near base (figs. 28 — 

 32) ; arolia bristle-like; e'ytra not hyaline or glassy. 



Subfamily VII. Der^eocorin^e, p. 882. 



hh. Body usuaUy elongated, often linear; claws usually sharply 



bent, not cleft near base (figs. 18 — 21) ; elytra often hyaline 



or glassy, sometimes with a sharply defined inverted Y- 



shaped red or fuscous mark. 



Subfamily VIII. Dicyphin/E, p. 905. 



//. Pronotum not constricted to form a coHar; sometimes with a 



somewhat flattened apical collar, then the abdomen constricted 



at base and the claws curved only at extreme tips (figs. 1— jl7). 



Subfamily IX. Phylin^e, p. 914.
