Eugereon is a remarkable Permian fossil, with jaws that are typically hemipterous except that the second maxillae are not fused and with cockroach-like wings.
He found on the same day on a bud of vetch, specimens of black ants (Camponotus sericeus and C. cosmicus), black ant-like Hemipterous insects (Megapetus atratus) and the antlike Orthopteron (Myrmecophana fallax) (cf.
WATER-BOATMAN, an aquatic hemipterous insect of the family Notonectidae, of which the best known species (Notonecta glauca) is a prominent feature in the pond-life of Great Britain.
Galls are formed also by hemipterous and homopterous insects of the families Tingidae, Psyllidae, Coccidae and Aphidae.
These homologies of the hemipterous jaws were determined by J.
In the Hemipterous group of the Rhynchota ant-mimicry is illustrated by the larva of a British species of Reduviidae (Nabis lativentris) in which the forepart of the abdomen is furnished on each side with a patch of white hairs leaving a central narrow dark portion in imitation of the waist of the ant; and also by an East African species (Myrmoplasta mira) which in its general form exhibits a close resemblance to an ant (Polyrrhacis gagates) which occurs in the same neighbourhood.
