54 IOWA STUDIES IN NATURAL HISTORY 
Pronotum thickly, uniformly punctured, the three pale lines which are 
continuous with those of tylus and juga diverging from before back- 
wards; antero-lateral margins smooth, somewhat sinuate; humeral angles 
rounded, not prominent; callosities pale yellow, distinct, sometimes en- 
closing a small punctured area. Scutellum long, narrow, the punctures 
gradually diminishing in size from base to apex which is very sharp and 
slightly depressed; a median, longitudinal, smooth, pale calloused ruga 
extends from base to apex. Hemelytra pale yellow, uniformly punctured 
with fuscous, a little narrower than abdomen; costal margin pale clay 
yellow with much finer reddish or fuscous punctures; membrane hyaline, 
undotted. Venter pale clay yellow, smooth at the middle; at the sides the 
series of fuscous punctures is confined to the conspicuous longitudinal 
line above mentioned; a series of irregularly arranged red dots along the 
margin outside this line; stigmata black; an elongate and semi-trans- 
versely striate stridulating area extends on either side of the first, second 
and third visible ventral segments. Legs slender, pale yellow, the bases 
of the femora unspotted, the apical two-thirds dotted with red, the 
tibiae darker and more thickly dotted. Length, 11.0-13.0 mm. Width 
across pronotum, 3.0-3.5 mm. 
The extremely slender and elongate form together with the 
inflated, triangular second antennal segment and the peculiar 
abdominal stridulatory apparatus will at once distinguish this 
insect from any of our other pentatomids. 
Professor Osborn records a single specimen taken from the 
erest of a hill near Sioux City and remarks: ‘‘I know of no 
previous record for this species above the lower austral zone, 
but the Missouri valley doubtless furnishes conditions more 
nearly like the south and provides for the northern extension 
of such species. ..°. .’’ «(Proc:-ta.- Acad saeey ao: 
1898.) This record stands alone for the state. The type local- 
ity was Texas and the species has also been recorded from Colo- 
rado and New Mexico. My own material is all from Texas. 
Tribe HatyiIni (Stal) 
This tribe, comprising about 225 forms, is best represented in 
the Australian and Ethiopian regions. Thirteen species are 
recorded from North America, three of which have been taken 
in Iowa. All belong to the genus Brochymena. The diagnostic 
characters of the tribe may be thus briefly stated: 
Head elongate, the sides not distinctly sinuate in front of eyes. An- 
tennae of from three to five segments (The North American forms all have 
five antennal segments); antennal tubercles visible from above. Rostrum 
long, slender, usually reaching abdomen. Eyes very prominent. Tibiae 
unarmed. Abdomen with a more or less distinct longitudinal furrow.
