SUBFAMILY I. — PENTATOMIN^E. 163 



number of specimens have been taken in August. We have 

 collected them on hazel, wild black cherry and often on wild 

 grape growing along the edges of woods and in more or less 

 shaded and moist situations. On Aug. 24 we once found the 

 nymphs common on basswood trees, and I have in my collec- 

 tion both nymphs and eggs taken on basswood Aug. 15." 



110 (180). Acrosternum marginatum ( Palisot de Beauvois) , 1805, 147. 



Close to hilare. Slightly smaller and less narrowed behind. Edges 

 of upper surface more reddish; apex of scutellum less produced apically, 

 its tip more broadly rounded. Ventral spine longer and more slender. 

 Paired basal plates of female genitalia with their hind margin concave; 

 in hilare broadly obliquely rounded. Male genital plate differing as 

 shown in key. Length, 14 — 15 mm.; width, 8 — 8.5 mm. 



Cape Sable, Fla., Feb. 23 — April 5, two specimens beaten 

 from foliage in dense hammocks (W.S.B.). Vera Cruz, Mexico, 

 March 20 {0 shorn) . Although mentioned by Uhler as occur- 

 ring in Florida, the Cape Sable record is the first one from a 

 definite station. It is a neotropical species recorded so far in 

 the United States only from Florida, Texas, Arizona and Cali- 

 fornia. Van Duzee (1907, 10) wrote of its occurrence in Ja- 

 maica as follows : "Abundant everywhere on bushes, especially 

 in the dry hot fields about Kingston. They fairly swarmed on 

 weeds and low bushes along the river bank south of Hope Bay." 



This species is very close to hilare, but differs especially in 

 the secondary sexual characters. Stal evidently overlooked the 

 differences in the genital plates of both sexes of the two 

 species, as he says of marginatum (1872, 42) : "A r . hilari maxime 

 affmis, spina basali ventris nonnihil longiore, staturaque paullo 

 breviore differt." 



XX. Banasa Stal, 1860, 24. 



Small or medium oval or elongate-oval species having the 

 sides subparallel, not dilated behind ; head porrect or feebly 

 declivent, scarcely longer than its width across the eyes, its 

 apex rounded ; cheeks usually flat, equalling tylus, their mar- 

 gins sinuate in front of eyes ; beak usually reaching or sur- 

 passing base of second ventral, its first joint slightly shorten 

 than bucculag, second about as long as third and fourth united ; 

 antennas slender, first joint shorter than head, second about 

 half the length of fifth, 3 — 5 subequal, the fifth slightly the
