SUBFAMILY I. — PENTATOMIN^. 119 



band as described in key; scutellum tipped with dull reddish; membrane 

 hyaline, without spots; connexivum and ends of ventral plates with a 

 small black point on the incisures; under surface yellow or greenish-yel- 

 low, the tip of beak fuscous. Head narrowed toward apex which is 

 broadly rounded ; cheeks as long as tylus. Basal half of scutellum with 

 a few narrow, pale transverse rugae, the punctures intervening; connexi- 

 vum narrowly exposed. Genital plate of male with hind margin subtrun- 

 cate or very broadLy emarginate. Other characters as in key. Length,

Mission, Tex., Dec. 5 (///. Nat. Hist. Surv. Coll.). A neotropi- 

 cal species which, according to Barber (1914, 523), has been 

 taken by Mrs. Slosson in southern Florida. Recorded also by 

 Van Duzee (1917, 53) from Florida, Arizona, Texas and Cali- 

 fornia. The Pentatoma tceniola Dallas (1851, 250), described 

 from Central America, is a synonym. The pronotal band be- 

 tween the humeral angles is testaceous, scalloped and margined 

 behind with brown or crimson. It was found by Van Duzee 

 (1907, 9) in Jamaica "On a low whitish succulent weed, allied 

 to Chenopodium, growing along the roadside." 



77 (163). Thyanta rugulosa (Say), 1831, 7; I, 319. 



Broadly oval, subconvex, small for the genus. Above pale green 

 fading to dull greenish-yellow, marked, especially on scutellum, with 

 small brownish punctures, tip of scutellum yellow; tergum black at base, 

 the last three segments and the connexivum green or greenish-yellow; 

 under surface green or greenish-yellow, thickly marked with small green 

 punctures. Head broadly sinuate in front of eyes, the apex bluntly 

 rounded; cheeks slightly surpassing tip of tylus; antenna? short, second 

 joint longest, fourth and fifth subequal, third one-half the length of 

 second. Pronotum with front portion strongly declivent, side margins 

 broadly but evidently concave, hind angles obtusely rounded; disk with 

 several narrow, transverse rugae, the most distinct of which is on the 

 front portion and ends in the callosities each side. Connexivum rather 

 broadly exposed ; osteole with tube nearly as long as canal, the support- 

 ing plate very rugose. Length, 6 — 7 mm. ; width, 4 — 4.5 mm. 



Cape Sable, Fla., Feb. 23 (IT. S. B.) ; beaten from foliage of 

 the saffron plum, Bumelia angustifolia Nutt. This is a western 

 and southwestern species, ranging from Nebraska to Utah, 

 California, Texas and Arizona, and has not before been re- 

 corded from east of the Mississippi, though Uhler (1872, 399; 

 1876, 290) mentions it as occurring in Cuba. Of its local habi- 

 tat in the west Uhler (1877, 403) states that in Clear Creek 

 Canyon, Colo., it was moderately common "on wild gooseberry 

 and several kinds of bushes which grew near the running
