ii. Body and appendages linear, extremely slender; antennae 

 elbowed at end of joint 1, the latter clavate; eyes distant 

 from base of head ; apical half of femora clavate. Ter- 

 restrial or thamnophilous ; probably phytophagous. 



Family X. Neidid^e, p. 331. 

 hh. Ocelli absent; membrane with two large cells at base from 

 which extend seven or eight branching veins (fig. 6, d) ; 

 osteola absent; length, 8 — 18 mm. Terrestrial or tham- 

 nophilous; phytophagous. 



Family XII. Pyrrhocorid^e, p. 437. 

 gg. Tarsi 2-jointed; body usually strongly flattened, both above 

 and beneath. 

 k. Elytra not lace-like or closely reticulate to form cells with 

 membranous centers. 

 I. Ocelli absent; body not covered with pile; membrane usual- 

 ly with veins ; claws without arolia ; length, 2.5 — 9 mm. 

 Arboreal, living beneath bark. 



Family IX. Aradid^e, p. 287. 

 //. Ocelli present; antennae 4- or 5-jointed, joints 1 and 2 

 thicker than the others (fig. 6, j) ; body densely clothed 

 with a very short velvety pile; clavus almost similar in 

 texture to the membrane, the latter without veins (fig. 

 6, «) ; head and thorax sulcate beneath; length not more 

 than 2.5 mm. Hygrophilous or semiaquatic; predaceous. 

 Family XXI. N.eogeid,e, p. 605. 

 kk. Elytra lace-like or closely reticulated to form areolae or cells, 

 these usually with a membranous center (fig. 6, g) ; length, 

 less than 5 mm. Terrestrial, thamnophilous or arboreal ; 

 phytophagous. Superfamily TINGIDOIDE^E, p. 445. 



ff. Beak 3-jointed. 

 m. Tarsi 2-jointed; ocelli present, widely separated; membrane 

 without veins; claws (in our species) with arolia; length 

 1.8 — 2.5 mm. Arboreal on foliage of royal palm; phy- 

 tophagous. Family XIII. ThaumastocoridjE, p. 444. 

 mm. Tarsi 3-jointed. 

 n. Ocelli present. 

 o. Membrane, when present, without veins; clavus of same 

 texture as membrane (fig. 6, e) ; corium somewhat thick- 

 ened; elytra often absent; color more or less greenish; 

 length not more than 4 mm. Semiaquatic; predaceous. 



Family XXII. Mesoveliid^e, p. 612. 

 oo. Membrane with distinct veins, these forming three to five 

 long closed cells (fig. 6, /) ; clavus and corium alike in 

 texture; head short and broad; eyes large and promi- 

 nent; length 2.5 — 8 mm. Littoral or hygrophilous; pre- 

 daceous. Family XXXIII. Saldid^e, p. 1002. 

 nn. Ocelli absent; elytra reduced to small pads, without a mem- 

 brane; length less than 6 mm. Parasitic. 



Family XXIII. Cimicid^:, p. 616.
