SCUTELLEROIDEA—DOUGLAS LAKE REGION 61 
siderably larger than C. bimaculata, the only other black and 
red representative of the Scutelleroidea mentioned in this paper 
up to this time. The present form averages from 8.0 to 11.5 
- mm. in length. 
Perillus exaptus (Say) 
I have one specimen of this species in my collection, a female 
taken July 24, 1920, by M. H. Hatch, at Big Stone Bay in 
Emmet County. The light markings are reddish yellow with the 
extreme margins of pronotum, hemelytra and connexivum 
palest. The anterior femora are armed with a very low blunt 
tubercle in place of the stout spine characteristic of the pre- 
ceding species. 
Apateticus cynicus (Say) 
This is the largest, although apparently one of the less com- 
mon pentatomids of the region. A female which I have measures 
19.0 mm. in total length; the males average somewhat smaller. 
I have but two specimens, a male and a female. The latter 
was taken in beach drift July 26, 1919, while the male was 
picked from the clothing of a visitor at Grapevine Point, August 
13. Specimens of the species were not taken during the 1920 
season. 
Apateticus bracteatus (Fitch) 
This is the more common of the two larger forms of this 
genus which occur in the region, a series of eight adults repre- 
senting our efforts for the seasons of 1919 and 1920. 
My best haul of this species was made on July 16, 1919, 
when I took four adults, two males and two females, in addition 
to a fourth instar nymph. They were swept from willows 
growing in a low, swampy, uncultivated area about one and 
one-half miles north of North Fishtail Bay. On either side of 
this narrow area a forest fire had burned—indeed, it was still 
smoldering on this date. One of the adults had apparently just 
cast the last nymphal skin for the body integument was still 
soft and a little paler than usual. My other specimens, with 
the exception of two, have been taken on willow. A single 
female was found in beach drift July 22 and, by a curious coin- 
cidence, my only adult specimen taken in 1920 was found in 
a similar situation on the same date in July.
