separated from both of these by having the antennae long and 
slender and the third and fourth joints subequal. 
Malar space distinct ; clypeus arcuately emarginate (the depth 
of the emargination varies considerably) ; antennal furrows com- 
plete but not strong ; orbitai carina obsolete ; posterior orbits 
narrower than or subequal with cephalo-caudad diameter of the 
eye ; antennae long and slender, pedicellum wider than long, third 
and fourth joints subequal; head and thorax shining, almost 
impunctate ; tarsal claws cleft, inner tooth shorter ; first trans- 
verse cubitus present ; nervulus its length from the basal ; hind 
wings with one discal cell, nervellus at right angles with the anal 
vein ; apical joints of the hind tarsi shorter than the two prece- 
ding. 
Type.—Poectlosoma mgriceps, Cameron. 
Monostegidea nigriceps (Cameron) Rohwer. 
Poecilosoma mgriceps, Cameron, Jn. Bombay Nat. Hist. Soc., Vol. 
TY, 1902) p.442: 
This species is represented in material received from the 
Indian Museum from the following localities :— 
Darjiling, altitude 7,000 feet. Two males collected by C. 
Paiva. Kurseong, altitude 5,000 feet. Two females and three 
males ; collector not given. 
Siliguri, base of the East Himalayas. Three females collected 
by Museum collector. 
Ghumti, altitude 4,000 feet. One female collected by F H. 
Gravely. 
Monostegidea leucomelaena, sp. n. 
This resembles to some extent Zaxonus fulvipes as described 
by Cameron, but itis not in agreement with Cameron’s description 
in many characters. It can readily be separated by the pale spot 
on the scutellum. 
Female.—Length 6mm. Anterior margin of the clypeus deeply, 
narrowly, arcuately emarginate, the lobes broad, obtusely rounded 
apically ; supraclypeal area rectangular in outline, strongly con- 
vex; supraclypeal foveae greatly reduced, below the ontennal 
fovea ; middle fovea crescent-shaped ; antennal furrows uninter- 
rupted, not complete dorsally ; no depression in front of the anterior 
ocellus ; postocellar furrows distinctly defined, angulate anteriorly ; 
postocellar line less than one half as long as the ocellocular line, 
shorter than the ocelloccipital line ; third, fourth and fifth anten- 
nal ioints subequal ; stigma gently rounded on the lower margin ; 
transverse radius joining the radius slightly beyond the middle of 
the third cubital cell ; sheath straight above, obtuse at apex and 
obliquely rounded below. Black with white markings ; head 
black ; mouth parts except the apices of the mandibles, face 
below the antennae, inner orbits to the top of the eye, posterior 
orbits to above the upper margin of the eye, white ; pronotum
