General form elongate oval, narrowed, not contracted much posteriorly. 
Color dull yellowish with pale yellowish markings and fairly regularly 
arranged deep black punctures. Head very convex, coarsely, irregularly 
punctate, the calloused median line more or less impunctate, the punctures 
finer and closer on either side of it; edges of head undulate; anteriorly 
the head is rather abruptly narrower and the juga are much longer than 
the tylus, approaching but usually not uniting, thus leaving a deep, nar- 
row incisure. Antennae with three basal segments yellowish, the two 
apical segments blackish rufous; second segment longer than third. Ros- 
trum dull yellowish, extending between posterior coxae; apical segment 
blackish. Pronotum more coarsely punctate on anterior half, the pale yel- 
lowish median line and lateral margins impunctate, the lateral edges 
straight, blackish; humeri rounded, a little swollen. Scutellum rather 
large, gradually becoming more finely punctate towards apex which is 
broadly rounded and not much narrowed; a median, impunctate, pale 
yellowish calloused line and a similar abbreviated line at each basal angle. 
Hemelytra regularly punctate, as wide as abdomen, the apex broadly 
rounded, somewhat sinuate; membrane whitish. Tergum black, punctured, 
with a pale yellowish impunctate margin. Venter brownish black, slightly 
bronzed, deeply, coarsely, rather regulariy punctate, the margin pale yel- 
low. Ventral plates of thorax brownish maculated with yellowish and 
coarsely, irregularly punctate. Legs yellowish with irregular black points; 
apical tarsal segment and tarsal claws infuscate. Length, 4.5-5.0 mm. 
Width across pronotum, 3.0-3.5 mm. 
Neottiglossa undata is readily distinguishable from any of our 
other pentatomids by its regularly elongate oval outline and 
trim appearance along with the characters mentioned above. 
Osborn listed it as ‘‘Not common.’’ in Iowa (Proce. Ia. Acad. 
Sei., I, Pt. II, 121, 1892), but in our experience it has usually 
been common in suitable situations and in some seasons is even 
abundant under favorable conditions. In a previous note on 
this species by the writer (l. c.), it is recorded as very common
