monest in June and July. Nymphs were common at Dubois in August, 
1917. 
GALGUPHA ATERRIMA, Sp. 0. 
Male and Female—Similar in color to nitiduloides. 
Structurally similar to nitiduloides, differing as stated in key, and 
also in having the tylus more distinctly beaded at apex above, and the 
upper margin of the hypopygial plate of male decidedly reflexed. 
Length, 4.25—5 mm. 
Type, Odin, Ill., May 12, 1902. Paratypes: Havana, IIl., August 15, 
1907; Dongola, May 10, 1917; Normal, June 14, 1882; and one male with- 
out data. Allotypes: White Heath, June 18, 1906; Grand Tower, June 
27, 1906; Urbana, June 30, 1888; Cobden, April 12, 1883; one labeled 
Southern IIl.; one labeled N. Ill.; and two without data. All the foregoing 
specimefis with data are from Illinois. I have also before me a male and 
female from Beltsville, Md., April 30, 1916, and June 15, 1913 (W. I 
McAtee). 
This is very probably the species referred to by Van Duzee as nitid- 
uloides var. in his Annotated List of the Pentatomidae, page 5.* 
4. CoRIMELAENA White 
In addition to the characters listed in the key for the separation of 
Corimelaena from its allies, the chitinized portions of the wings present 
venational characters that are valuable. The costal region lacks the linear 
depressions that are so evident in the species of the other genera and only 
two distinct sutures are present, as indicated in Figure 56, Plate XIX. 
The scutellum differs from thatyof allied genera in having an impressed 
line on basal half near to lateral margins, and the pronotum is distinctly 
impressed near posterior lateral angle, causing its margin here to be 
nearly vertical. 
Key To SPECIES 
Chitinized portion of wing entirely black, ‘punctate to lateral margin; basal geni- 
tal plate of female about twice as wide as its greatest length; median trans- 
verse depression of pronotum very faint; fore tibia with 5 postero-dorsal

Chitinized portion of wing partly yellow or white, or species not as above. 
Hind tibia with 3 or 4 postero-dorsal spines, the basal one very small, close to 
base; if all spines are very small or absent the chitinized portion of 
wing is rounded at apex, and the pale color extends mesad of cubitus. 
Large species, averaging 4 mm. in length; pale border of wing not broadened 
near base, or if so the apex of elytra is acute. 
Pale border of wing not broadened near base; dorsum of pronotum with 
sparse large punctures and numerous very small interspersed punc- 
tures on disc. 
Basal genital plates of female much wider than long (PI. XIX, Fig 65); 
penultimate segment before genital plates without a lateral carina...
