Fig. 1. Felisacus amhoinae n. sp. Head and pronotum. 
ately raised, smooth, with sparse, longish, 
erect pale hairs; two deep punctures on scuto- 
scutellar suture. 
Hemelytra long; costal margins of corium 
nearly straight and parallel, slightly over twice 
as long as total length of pronotum (48:23); 
outer margin of cuneus rather less than 0.33 
as long as corium (14:45, 15:48). Outer mar- 
gin of inner division of clavus raised and 
thickened, with a row of long, pale, erect 
hairs. 
Length: 3.75 mm. Width across hemelytra: 
Male, 0.8 mm.; female, 0.95 mm. 
COLOUR: Shining above. Head, pronotum, 
and scutellum yellowish brown. Head with 
red markings anteriorly, along inner margins 
of eyes, and narrowly in mid-line. Eyes red- 
dish brown or reddish black. Antennae with 
segment I red or reddish brown, II red or 
reddish black. III and IV black. Rostrum 
yellowish brown. Sides of anterior division 
of pronotum sometimes red. Base of prono- 
tum inside posterolateral angles more or less 
infuscated. Swollen outer part of anterior lobe 
of scent-gland spout red. Legs yellow; apex 
of femora and base of tibiae red, the red 
colouring sometimes extending along entire 
upper surface or even whole of tibiae and as 
a narrower dorsal line on femora; tarsi in- 
fuscated at apex. Whole of cuneus coloured, 
orange or orange-red, with inner margin usu- 
ally widely and costal margin more narrowly 
red. Embolium red at apex and narrowly red 
or reddish brown along costal and inner mar- 
gins. Inner half of clavus red, at least on mar- 
gins; outer half translucent, pale. Inner margin 
of corium along apex of clavus more or less 
widely dark brown or black. Apical margin 
of corium as far as cuneus red, with adjacent 
area more or less infuscated. Membrane with 
margins narrowly infuscated; veins testace- 
ous, more or less tinged with red. Rest of 
hemelytra clear hyaline. Veins of hind wings 
brown. Ventral surface of body yellowish 
brown. Dorsal surface of abdomen red. 
TYPES: Holotype male, allotype female, 1 
paratype male, Amboina (E. Indies), F. Muir. 
Deposited in the California Academy of 
Sciences. 
This is the species noted by Usinger (1946: 
70). 
F. amhoinae belongs to the elegantuhis group 
of species (see below) and is perhaps most 
closely related to ochraceus Usinger, from 
Guam. It is distinguished from the latter, 
however, by marked differences in colour, by 
the less protuberant eyes, by the basal emar- 
gination of the pronotum being less widely 
rounded and more angulated in the middle, 
and by the proportionately somewhat shorter 
cuneus. It differs from filicicola (Kirkaldy) in 
colour, the smaller size, the eye wider in 
proportion to interocular space, the head
