SCUTELLEROIDEA OF IOWA 95 
more sparsely punctate than scutellum, the basal half of costal margin pale 
yellowish and impunctate, the apex more distinctly sinuate than in WN. 
undata; membrane whitish. Tergum black, densely punctured, with a 
narrow, pale yellowish, impunctate margin of uniform width. Venter 
black, deeply, coarsely, rather regularly punctured, the margin pale yellow, 
impunctate. Ventral plates of thorax black sometimes with faint yellowish 
maculations; more coarsely and irregularly punctate than venter. Legs 
yellowish with irregular brownish maculations; tarsal claws and apex of 
last tarsal segment infuscate. Length, 4.0-4.5 mm. Width across pro- 
notum, 2.0-3.0 mm. 
This is our smallest representative of the subfamily Penta- 
tominae and in addition to the characters above given it may be 
distinguished from its congener in our fauna by the fact that 
the ostiolar canal is prolonged outward in a fine though distinet 
wrinkle. In N. undata the wrinkle is merely a faint slender ridge 
extending outward for a short distance from the ostiolar opening. 
Neottiglossa sulcifrons is typically a southern species, occur- 
ring more commonly in the southwest and has also been. re- 
corded from Nebraska. It was first recorded from Iowa by the 
writer in 1915 (I. c.). While apparently more common in 
southern Iowa several specimens are at hand from the north- 
western part of the state. The localities represented are, Bur- 
lington, Chariton, Emmetsburg, Ft. Madison, Glenwood, Lake 
Okoboji, Shenandoah and Sioux City. 
Half grown nymphs have been taken in late June and in July 
at Burlington, Ft. Madison and Glenwood. MHibernating indi- 
viduals have not been discovered and practically all the speci- 
mens have been swept from sparsely growing blue grass and 
timothy. At Burlington on June 29, this insect was found in 
considerable numbers on the short blue grass growing in an 
orchard; and at Sioux City on July 20, several specimens wera 
taken in a somewhat similar situation although at the latter 
place the orchard was not pastured as at Burlington and the 
long blue grass was intermingled with more or less timothy. 
More than fifty specimens are at hand from the localities men- 
tioned above. This species affords a good illustration of the 
encroachment of a typical southern species upon our fauna.
