30 SOUTH AMERICAN TIPULIDAE 
sternite of the male hypopygium. This species is based on a 
member of the Lloyd collection and is described from one of the 
two specimens referred to monilifera in my previous paper. ^ 
The other specimen is here described as T. armillatus n. sp. 
and so monilifera is not yet definitely known from Colombia. 
Tipula armillatus sp. n. 
Monilifera group ; antennae of the male very long, nearly as long as the wing 
(antenna, 12.8 mm.; wing, 14 to 15 mm.). 
Male. — Length, 13 to 14 mm.; wing, 14.2 to 15.2 mm.; antennae, 12.8 to 
12.9 mm. 
Similar to T. vionilifera Loew and T. mitua sp. n., differing as follows: anten- 
nae very long and slender, the longest for any member of this group of species, 
being some four-fifths the length of the wing (see plate IV, fig. 8) ; segment one is 
quite normal, segment two with a dense brush of black hairs on the dorsal inner 
surface; remainder of the organ light yellow, the last ten flagellar segments 
with the brownish black basal swelling, the slender stem passing into dark 
brown at about mid-length of the organ. 
Thoracic dorsum fight brown, the lateral stripes quite lacking, the brown 
setigerous punctures on the interspaces scanty. Abdomen mostly dark brown 
except on the basal segments. Hypopygium with the ninth tergite having 
the median furrow reduced to a mere line as in the specialized members of this 
group, the latero-caudal angles prominent, sfightly incurved; ninth pleurite 
very small, reduced to an elongate-oval lobe on the caudal face of the ninth 
sternite; eighth sternite (see plate V, fig. 8) prominent, the caudal margin 
gently concave, medially bearing a small lobe which is provided with a tiny 
tuft of silvery hairs. 
The wing-pattern is shown in plate III, fig. 6; that of Tipula vionilifera 
Loew in plate III, fig. 5. 
Habitat. — Colombia. Holotype, cf, La Cnmbre, Colombia, 
altitude 6600 feet, May 16, 1914 (Parish coll.). Paratype, d^ , 
Popayan, Colombia, altitude 6590 feet, March 1, 1912 (Lloyd 
coll.). 
The longer antennae and the different hypopygium in the male 
serves to distinguish armillatus from the related species with brown 
and white wings {^nonilifera Loew, mitua sp. n.) ; moniliformis 
Roder has the wings diversified yellow and hyaline. 
The paratype was previously determined as T. monilifera in 
an earlier paper by the author, as mentioned under the descrip- 
tion of T. mitua.
