Psyche 
[April 
Female genital segments pale yellowish brown, posterior margin 
of the penultimate segment and the whole of the last segment 
black above. 
Length of body: cf 3 mm., 9 3.5 mm. 
Holotype, d', allotopotype, 9; and many paratopotypes; 
Ampin near Tainan, South Formosa, Sept. 9, 1921, (Teiso Esaki). 
This species is one of the smallest in the genus and is most 
readily distinguished from other species by the characteristic 
markings of the head, and by the absence of the fringe of long 
hairs on the first intermediate tarsal joint. It is somewhat 
allied to the species of the Genus Metrocoris in respect to the 
structure of anterior femur and tarsus, but the presence of the 
fringe of long hairs on the intermediate tibia, coloration and 
general aspect, as well as the marine habitat, make the species 
more rationally referable to Halohates than to Metrocoris. 
This species is found on a small stream of salt water con- 
necting a pond to the sea, and a large number of specimens 
swarm in a shaded surface of the stream. 
Halobates shiranui sp. nov. (Fig. C). 
Body ashy gray, short and broad. Head black with brown 
pubescence on lateral sides, vertex without markings; eye brown. 
Antenna black, first joint about as long as the third and fourth 
joints put together, third and fourth joints nearly equal in 
length. Rostrum black, reaching the anterior coxa. Pronotum 
black, anterior margin moderately sinuate, posterior margin 
very slightly so, distinct transverse impression at the middle of 
pronotum. Meso- and metanotum together almost as long as 
broad, swollen and black. Anterior leg black with brown coxa 
and trochanter; tibia nearly as long as femur; first tarsal joint 
joint very short, almost as long as thick, about one-fifth the 
length of the second joint; claws arising at the middle of the 
second joint. Intermediate and posterior legs black, femora 
tapering toward the apex; intermediate tibia a little shorter 
than femur; first tarsal joint about twice the length of the second;
