TEN NEW SPECIES OF EMPIDIDCE (DIPTERA) 
By A. L. Melander 
Riverside, California 
In collecting any group of insects some species are rarely en- 
countered while others are common. In the Empididae species 
of Empis , Hilara , Rhamphomyia and Platypalpus are numerous 
and are frequently taken, but it is a fortunate day when the 
collector can find a Ragas, a Gloma, or an Anomalempis. These 
last three represent archaic genera, and perhaps in their con- 
servative characters they are handicapped in competition with 
those genera where speciation runs rife. 
In the following pages are presented descriptions of ten new 
Empididae, selected because of rarity or other noteworthy in- 
terest. Unless otherwise mentioned the specimens were collected 
by myself and the types are in my extensive collection of this 
family. 
Anomalempis archon, n.sp. 
Female. Length 3.75 mm. Entirely black, the halteres, pul- 
villi, abdominal hairs and terminal fringe of abdomen alone 
whitish. Sides of front coarctate, at middle one-fifth the length 
between antennae and front ocellus, hairs of occiput conspicuous. 
Dorsum of thorax and abdomen polished, pleurae and coxae gray 
pruinose, dorsocentrals in more than single row, acrostichals 
biseriate, notal hairs long and thin. Hairs of middle coxae longer 
than trochanters, all femora with setae underneath, each tibia 
with about six extensor setae. Wings hyaline, stigma narrow, 
pale brown. 
Holotype: Katmai, Alaska, August, 1917, received from Pro- 
fessor J. S. Hine. 
A larger and more bristly species than A. tacomce Melander 
from Mount Rainier, Washington, but in structure and neura- 
tion exactly resembling the figure in Genera Insectorum, fasc. 
185, pi. 5, f. 39 (not f. 38, which is Syndyas polita Loew). In 
the Washington species the sides of the front are much less
