GRYLLOBLATTODEA 107
collected on Sulphur Mountain, Banff, Alberta, Canada, at an altitude of
6,500 ft. The adults arc amber-yellow and whitish, being covered with a fine
pubescence, and measure 16-30 mm. in length. The antennre are 28- or 29segmented
and the cerci eight-segmented. They occur in the soil or under debris,
moss, or stones in moist or wet places that are covered with snow for a
considerable part of the year. Specimens are therefore taken during the summer
period. The insects are apparently nocturnal or negatively phototropic,
rather slow of movement. In confinement they eat both plants and dead insects
and only rarely attack living insects. In nature they may subsist on
quantities of dead insects deposited by the melting snow and ice. Their black
eggs are deposited in the soil or moss by means of the ovipositor. This species
has also been taken at Lake Louise, Lake Agnes, and on Rundle Mountain in
the Canadian Rockies.
A variety. occidentalis Silvestri, collected at 4,200 to 5,000 ft. alt.itudes on
Mt. Baker, Wash., on June 21, 1922, by Silvestri differs from the above in having
30 to 32 segments to the antennre. Grylloblatta barberi Caudell is similar to
the preceding but has 40-segmented antennre and is 20 mm. in length. It was
taken on the North Fork of the Feather River, Plumas County, Calif., Jan. 23,
1923.
Grylloblatta nipponetzsis (Caudell and King) (Galloisia, Galloisiana), is a.
yellowish species 21 mm. long, with about 40-segmented antennre and ninesegmented
cerci. In the adult males there are paired membranous lobes on tarsal
segments I to IV and a single lobe on segment V. The claws have a minute
basal tooth. A Japanese illustration shows the abdomen to be much shorter
than the head and thorax (Esaki et a1., 1932). The specimens were taken under
and in decayed logs at elevations of 4,500 to 4,600 ft. on the slopes of the mountain
Nantai San, near Chezenji, Nikko, Japan, in August and September. The
insect is described as being very active, like a cockroach.
GryUoblatta notabilis Silvestri (Ishiana) is straw-colored, 13.4 mm. long, and
has the antennre 37-segmented. It was taken on a mountain near Michino-o,
Nagasaki, Japan, by Silvestri in June. 1925.
