SUBFAMILY I. — PENTATOMIN.-E. 151 



101 (148). Neottiglossa cavifrons Stal, 1872, 18. 



Oblong-oval, convex above and beneath. Above black or piceous- 

 black, shining; elytra and sometimes the basal portion of pronotum dull 

 brownish-yellow; usually two small spots on occiput, two near middle 

 of pronotum and a feebly curved short line each side of base of scu- 

 tellum, calloused and ivory-white; basal joints of antenna? reddish- 

 yellow, fourth and fifth fuscous; under surface black, faintly bronzed; 

 legs yellow, the narrow edge of abdomen and sometimes of pronotum 

 ivory-white. Head very broad, densely and finely punctate, its apex 

 broadly rounded, the entire deflexed front hollowed out to form a deep 

 regular almost circular concavity; tylus flat, surpassed by cheeks, which 

 are contiguous before it. Pronotum and scutellum evenly, densely and 

 shallowly punctate, the side margins of former a little concave. Under 

 surface finely and evenly punctate. Genital plate of male rather narrow, 

 its middle feebly depressed, its apex truncate, entire. Length, 4 — 5.2 

 mm.; width, 2.5 — 3 mm. 



Dubois and Knox counties, Ind. (W.S.B.). Dubois, 111., 

 May 23 (Hart). The Indiana specimens were taken May 14, 

 by sifting debris at the base of stumps and July 7 by sweeping 

 bush clover, Lespedesa, on the top of a high sandy knoll. Stal's 

 types were from Texas and it is listed by Van Duzee only from 

 that State, Utah and California. East of the Mississippi it is 

 known only from the southern fourth of Illinois and southern 

 Indiana. Hart (1919, 187) states that it "is not uncommon in 

 southern Illinois from April 28 to July 21, with nymphs on 

 June 20 and July 9. One of the nymphs was taken on Pycnan- 

 themum" Van Duzee (1904, 50) says that cavifrons and sulcifrons 

 "are close and possibly should be considered but varieties of a 

 single form." The structure and shape of the head in the two 

 is entirely different and there is no doubt but that they are 

 very distinct. 



XIV. Cosmopepla Stal, 1867, 525. 



Species of small size and oval convex form having the head 

 moderately declivent, as long as or longer than broad, cheeks 

 equalling the tylus ; antennae slender, pubescent, reaching base 

 of pronotum, second and third joints subequal, fourth and fifth 

 stouter, the fifth the longest; beak reaching base of second 

 ventral, its first segment one-half longer than bucculaa, second 

 a little shorter than third and fourth united; pronotum 

 with front portion strongly declivent, its side margins almost 

 straight, humeral angles obtusely rounded; scutellum broad, 

 reaching or a little surpassing tip of corium, its apex broadly
