368 DIPTERA 
I. GeNus BURMITEMPIS, COCKERELL 
Burmitempis, Cockerell, Amer. Journ. Sc. Vol. 44. p 367 (1917). 
Characters. — Head broad, dichoptic, third antennal joint very large, oblong-oval, hairy; 
with very long simple arista; wings large and broad, first basal cell long, emitting three veins from apex, 
and one from lower side, second posterior cell somewhat contracted apically, no discal cell, second 
basal small, narrow and nearly vertical, anal cell large and apically truncate, anal angle of wing 
rectangular; halteres enormous, with long thick knob; legs long, ordinary; genitalia small and simple. 
Dr. Cockerell located this genus in the Empididz, apparently nearest to Microsamia, but 
suggestive of the Tachydromiinz in some of its characters, — The removal of Microsania to the 
Platypezidae may carry with it this genus. If the vein arising from the lower side of the first basal cell 
is the anterior branch of the media and the lower outer side of the basal the long and longitudinally 
placed anterior crossvein then the homologies of the neuration are clear though strangely aberrent. 1f, 
however, the small vein at the apex of the first basal cell is the anterior crossvein then the radius has 
two branches and the media three, a condition not in conformity with expectations among the Diptera. 
From the data at hand the systematic position of this fossil can not be definitely stated,

2. GeNus DRAPETIELLA, MEUNIER 
Drapetiella, Meunier, Ann. Sc. Nat. (Zool.) 9 ser. Vol. 7, p. 86, note 3, p. 97 (1908). 
Characters. — This genus was located with Drafetis, differing by the ovate style-bearing third 
joint of the antennze and the greatly inclined second basal cell. Asa short style is anomalous in the 
entire subfamily Tachydromiinz and as the figure shows an impossible veination this genus is far from 
being certain. 1t possibly is an Ocydromiinz, with open discal cell, such as is shown by Eufhyneura 
aferta to-day.

3. GeNUS ELECTROCYRTOMA, COCKERELL 
Electrocyrtoma, Cockerell, Ann. Ent. Soc. Amer. Vol. 10, p. 22 (1917). 
Characters. — Resembling Bicellaría, but with lengthened arista, slender tibie and tarsi, no 
intercalary vein, and with the fork of second and third veins much before anterior crossvein. — Thorax 
gibbous, finely hairy; discal cell open but with a slight bend in fourth vein at two-fifths of its last 
section ; base of front femora about two times as thick as apex.
