the last ventral and genital plate of male paler. Head with hind lobe 

 strongly declivent, attached to the thorax by a short, very slender neck. 

 Joint 1 of antennas reaching base of pronotum; 2 more slender, slightly 

 shorter; 3 only one-fourth the length of 2, half as long as 4. Meso- and 

 metanotal spines slender, subequal, the front one erect, the hind one more 

 tapering and curved slightly forward. Ventrals 3 — 5 each with a pair 

 of short submedian spines hear hind margin. Front femora armed be- 

 neath with two stout spines and numerous short seta?, the spines white 

 with black tips. Genital plate of male short, scoop-shaped. Length, 

 9.5 — 10 mm. 



Dunedin, Fla., Feb. 7 ; one male beaten from buttonwood, 

 Conocarpus erecta L. (W.S.B.). Raleigh, N. Car., June (Brim- 

 Icy) . The only other recorded specimen from Florida is one 

 taken September 24 by Davis at Miami. Known also from 

 South Carolina and Mississippi. This is the species usually 

 listed and recorded as 5". spiniventris Sign., originally described 

 from Mexico and recorded from Cuba and Arizona, and it is 

 very possible will prove to be that species. McAtee & Malloch, 

 not having seen Signoret's type of spiniventris, do not include 

 it in the U. S. fauna, stating that the figure of Signoret shows 

 the "mesonotal spine as erect and acute and the metanotal 

 swollen at tip and curved so as to extend forward past the 

 mesonotal spine." Uhler's remark regarding S. spiniventris 

 (1884, 277) will well apply to the species at hand. Of it he 

 wrote : "This is an extremely curious insect, built in the most 

 intangible manner." The short, wide head, very large eyes, 

 slender neck, lobes of pronotum so formed as to resemble a 

 dumb-bell, and slender antennae and legs, densely clothed with 

 long fine silky erect hairs, make a combination unique in our 

 Heteropterous fauna. 



II. Empicoris Wolff, 1811, IV. 



Slender-bodied species of medium length, having the head 

 porrect, bilobed by a deep sulcus between the eyes, the front 

 lobe subquadrate, the hind one subglobose ; antennae much 

 longer than body, they, as well as legs, annulate with pale and 

 dark rings ; pronotum extending over mesonotum to base of 

 wings, its front lobe shorter than head, subquadrate, with sides 

 rounded, hind lobe oblong, nearly twice as long as front one ; 

 meso- and metanota and usually the first dorsal, each with a 

 short spine on middle of hind margin ; venation of elytra as in 

 figs. 6 and 8 ; front femora either with bristly hairs or spinose
