IQgI5 | EK. BRUNETTI: Notes on Ortental Syrphidae. 215 
Abdomen with Ist segment shining aeneous, often appearing 
like a prominent triangle on each side of the base of the 2nd 
segment. The 2nd segment black, with a broad, clear cut, bright 
yellow transverse uninterrupted band forming about one-third of 
the segment; remainder of abdomen normally orange yellow, 
unmarked, and though there are generally a few irregular obscure 
markings there is nothing in the nature of transverse black 
bands or pairs of spots. Abdomen distinctly shorter than the 
wings. Coxae all yellow (in only one specimen the hind pair show 
a slight darkening); remainder of legs wholly yellow, the hind 
tarsi a little deeper orange. 
Long. 6—7 mm. 
Baluchistan, Bushire, Katmandu (Nepal), Dharampur (Simla 
Hills), 5000 ft., 6—8-v-07 [Annandale] ; Agra, 4-iv-05; Ferozepore 
(Punjab), 28-iv-05 [Brunett?]. 
? Differing from the ~ only as follows. Vertex shining black 
or dark aeneous, with a concolorous stripe, narrowing considerably 
and approximately reaching the antennae. 
Abdomen about as long as the wings, 3rd and 4th segments 
with a wide black band on posterior margin. 
I took this form in abundance at both Agra and Ferozepore, 
in company with the ¢ ~ reterred to, during April, 1905 in fields 
of dry grass, stubble and general vegetation. : 
One @ from Purneah (Bengal), 8—g-iiiog [Paiva] agrees 
technically, but the wings and abdomen are equally long, and it is 
a little more robust. Long. 7 mm. 
It is difficult to differentiate this form from scriptus, L., yet it 
seems quite a distinct local race. Verrall notes the partiality of 
this species to form local races. Apart from size the ~ in the pre- 
sent form is exactly like scviftus with all yellow abdomen after the 
2nd segment, a form that species very often takes in European 
specimens, but on the other hand the ¢ does not so closely 
resemble the @ scriptus, the abdomen being mainly yellow, with 
black bands, instead of mainly black, with interrupted narrow 
yellow bands. 
B) 
Form ‘277, mihi. 
@ @ Shanghai, Simla, Nepal, Bengal. 
@ This differs from Form 1 only in the 3rd and 4th ab- 
dominal segments in the ~ having a narrow black band at the base 
and a broad one at the tip of each. The wings are as long as the 
abdomen. 
Long.6 mm. Shanghai, 17-iv-06 [Brunetti]; Songara, Bengal, 
3—5-ili-07. 
2 Agreeing with but the scutellum sometimes has some black 
hairs on the hinder part. ‘The abdominal black bands are broader. 
Vertex shining aeneous black, frons with a broad black stripe to 
the antennae, this stripe sometimes of uniform width, sometimes 
narrowing anteriorly.
