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 monilijera in my previous paper. ^^ 

 The other specimen is here described as T. armillatus n. sp. 

 and so monilijera is not yet definitely known from Colombia. 



Tipula armillatus sp. n. 



Monilijera 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. monilijera Loew and T. milua 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 light 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 speciaUzed members of this 

 group, the latero-caudal angles prominent, slightly 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 monilijera 

 Loew in plate III, fig. 5. 



Habitat. — Colombia. Holotype, cf, La Cumbre, 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 hj^popygium in the male 

 serves to distinguish armillatus from the related species with brown 

 and white wings {monilijera Loew, mitua sp. n.) ; monilijormis 

 Roder has the wings diversified yellow and hyaline. 



The paratype was previously determined as T. monilijera in 

 an earlier paper by the author, as mentioned und(^r the descrip- 

 tion of T. mitua.
