CHARLES P. ALEXANDER 29 
Tipula mitua sp. n. 
MoniUfera group; antennae tslender, moderately long (cf , 8.5 mm.); thorax 
brown without apparent stripes; wings variegated brown and white; male 
genitalia with the caudal margin of the ninth tergite deeply rounded, eighth 
sternite with a prominent median lobe that is directed caudad. 
Male. — Length, 15.5 mm.; wing, 19 mm.; antennae, 8.5. mm. 
Frontal prolongation of the head rather long and slender, light brown; palpi 
black, paler at the joints. Antennae moderately long (see plate IV, fig. 7) 
but with the segments slender as in monilifera; the antennae are less than 
one-half the length of the wings; the two basal segments are dull yellow, the 
remaining segments with the basal enlargement black, the stem dark brown, 
on the terminal segments almost black. Head light brownish yellow with a 
narrow dark brown median vitta. 
Thoracic praescutum brown without apparent darker stripes; on the inter- 
spaces between the usual stripes are numerous brown spots surrounding setiger- 
ous punctures; scutum and postnotum brown, narrowly edged around with 
dark browai; scutellum yellowish brown. Pleura dull yellow. Halteres 
moderately long, duU yellow, darkened toward the knob. Legs with the coxae 
and trochanters yellowish brown, broadly tipped with dark brown ; tibiae and 
tarsi dark bro^vTi. Wings brown and white, the shade of the brown a little 
paler than that of monilifera; venation and pattern as in plate III, fig. 4. 
Abdomen dull brownish yellow with the lateral margins broadly dark brown; 
terminal segments dark brown; sternites dull yellow. Hypopygium as in the 
monilifera group; ninth tergite (plate V, fig. 4) with the inedian furrow of the 
more generalized forms {exilis, et al.) reduced to a mei'e line; caudal margin of 
the segment broadly and evenly rounded. Ninth pleurite rather prominent, 
subrounded. Eighth sternite (plate V, fig. 7) prominent, with the caudal 
margin very convex, bearing an elongate fleshy median lolse, this lol^e directed 
caudad. 
Habitat. — Colombia. Holotype, 6^, Valle de las Papas, 
Colombia, altitude 10,000 feet, March 29, 1913, collected by Mr. 
John Thomas Lloyd. 
The specific name is that of a native Indian tribe occupying 
the same region as the species. 
This species is similar to monilifera Loew and armiUatus 
n. sp. in the dark brown and whitish wing-pattern, but differs in 
the shortness of the antennae in the male sex (8.5 mm., with a 
wing of 19 mm.) as opposed to monilifera with an antennal 
length of 10 mm. and armiUatus with the antennae over 12.5 
mm. in length. From T. carizona Alex, it differs in the diversified 
brown and white wings; from T. ornaticornis V. d. Wulp, by the 
color-pattern of the thorax and abdomen. It agrees with these 
two last species in the slender median appendage to the eighth 
TRAXS. AM. ENT. SOC, XLII.
