XI. Descriptions of new species of the Syrphid genus Calhicera 
(Diptera). By the late G. H. Verratt, F.ES. 
Edited by J. E. Corin, F.Z.8., F.E.S. 
[Read April 2nd, 1913.] 
THE following descriptions of new species of Callicera (one 
Palaearctic, two from the Oriental Region, and one from 
Central America), together with a detailed description of 
the British C. yerburyi, Verr., and a re-description of C. 
erratica, Walk., were written by the late Mr. Verrall some 
years ago, but were kept in MS. until such time as he could 
complete an elaborate paper upon the whole genus. This 
unfortunately he had not finished at the time of his death, 
and a critical examination of the unfinished MS. showed 
that it was not in a state for publication without so much 
editing as would practically make it cease to be the late 
author’s work, therefore it has been thought best to publish 
only the following descriptions. 
JO Here: 
C. LOEWI, n. sp. &. 
A rather small'species, with no black hairs at tip of abdomen, second 
antennal joint half the length of first, third joint more than twice the 
length of first two together, thorax with 3-5 conspicuous black stripes, 
abdomen with nearly all the first two segments and a large triangle on 
third segment, black. 
Face shining black with abundant golden pubescence, leaving 
bare a broad but not well-margined middle part which becomes 
narrow near the upper mouth edge. Frons all shining black ex- 
tending down the sides to below antennae and across under antennae, 
side-margins of face below this with a tolerably broad line of grey 
dust extending nearly to lower angle of eye, frons and antennal 
prominence all absolutely bare. Jowls shining black and _ bare, 
lower half of back of head with dense yellow conspicuous pubescence, 
but upper part of back of head with a shining aeneous rim narrowed 
at vertex, and with more sparse dark brown pubescence, but all 
upper part with abundant tolerably long orange pubescence. Vertex 
with dense black pubescence almost lost amidst dense dark pubes- 
cence of eyes. Eyes viewed from above with all the middle, ex- 
tending nearly to front, clothed with very dense brownish-black 
pubescence and the hind third apparently bare but really with long
