240 Records of the Indian Museum, [VoL“xae 
nepalensis), and Sibu, Sarawak, 2-vii-ro [Beebe], three females, 
that is seven specimens altogether. 
All these appear to come within the range of a single species 
possessing the following variations of character. The frons in the 
female from shining black to rich blue black; the antennal 3rd 
joint may be black on upperside or unicolorous; the dorsal tho- 
racic stripes vary in intensity and the 3rd pair of abdominal spots 
are wanting in one specimen; the wing tip varies from quite 
clear to distinctly and broadly brown infuscated; the hind tarsi 
vary from white to brownish yellow, the upper side of the meta- 
tarsus (and sometimes also the basal half of the succeeding joint) 
may be wholly or partly brown. 
Taking all things into consideration the chances are in favour 
of aurifrons, W., being the species at present referred to. 
A description of the specimen from Borneo is added, simply 
as such, as an augmentation of that of my nepalensis. In the o 
of the species under discussion, whatever it may be, the frons 
is two to three times as broad on the vertex as at the point of 
nearest contiguity of the eyes. There was an error in my descrip- 
tion, the frons not being black but brilliantly shining blue black. 
Eumerus aurifrons, Wied. 
Dr. Meijere makes sflendens, W., a synonym of this and redes- 
cribes the o , recording the species from Batavia, Semarang, Cey- 
lon and the Dammer Is. (Tijd. v. Ent. li, 218). This may be the 
species described by me as nepalensis (infra). 
Eumerus nepalensis, Brun. 
(Description of a specimen from Borneo). 
2 Borneo. Long. 5—6 mm. 
Head.—Frons distinctly narrowed at vertex, measuring at 
the greatest width, just above the antennae, one-fourth of the 
head; shining black, with a grey-dusted spot each side about the 
middle of the eyes and contiguous to these latter, the spots nearly 
meeting one another in the middle of the frons. Vertex with 
brown hairs. Back of head behind vertex and upper part of 
eyes, shining black, narrow, occipital margin imperceptible below 
middle of eyes, occiput dark grey or blackish. The margins of 
the face from opposite the base of the antennae, a little grey- 
dusted, and the face itself with a little yellowish hair. Antennae 
bright brownish yellow, upper margin of 3rd joint blackish, arista 
black, base a little pale. 
Thovax.—Shining black, with two well separated narrow 
whitish median stripes from anterior margin to behind transverse 
suture. Anterior part of dorsum a little aeneous in certain lights.
