I have before me male specimens of the following species 
which I expect to characterize more fully in the third part of my 
‘Synopsis of the Neotropical Tipulide.’’ 
Pachyrhina nigrolutea Bellardi. 
Macromastix chilensis Philippi. 
Tipula albifasciata Macquart. 
Tipula craveri Bellardi. 
Tipula edwardsi Bellardi. 
Tipula microcephala v. d. Wulp (which seems to belong to Holorusia Lw.). 
This name is preoccupied by T. microcephala Big. (1858), and I rename the 
South American species, 7ipula vanderwulpi n. n. 
Tipula monilifera Loew. 
Tipula moniliformis Roder. 
Tipula subandina Philippi. 
Tipula apterogyne Philippi. 
Tipula rufostigmosa Macquart. 
Tipula variinervis Bigot. (= picti-pennis Walker.) 
Pachyrhina macrosterna, sp. n. 
Thoracic stripes not complete, represented, when at all evident, 
only by spots at the margins of the preescutum; dorsal apical appendage 
of the & genitalia prolonged, stylet-like. 
oS Length, 10.8—10.8 mm.; wing, 11.4—11.8 mm. 
Middle leg, femur, 8 mm.; tibia, 8.9 mm. 
@ Length, 12.8 mm.; wing, 13.2 mm. 
Fore leg, femur, 8.9 mm.; tibia, 10.7 mm. 
Hind leg, femur, 9.8 mm.; tibia, 10.6 mm. 
& Head: Anterior prolongation of the front brownish-yellow, 
clearer yellow beneath and on the sides; palpi brownish; antennz, basal 
segments orange-yellow; 3d segment brownish-yellow; remaining seg- 
ments dark brown basally, gradually fading into the yellowish-brown 
apical portion of the segment; terminal three or four segments uniform 
brown. Front, vertex and occiput yellow, more brownish in the middle 
of the vertex, very broadly shiny, this mark not clearly delimited but 
embracing most of the space between the eyes. 
Thorax: Pronotum dull pale yellow; mesonotum, prescutum 
shiny, brownish-yellow, without clearly defined stripes; pleure dull 
with a pale yellowish bloom. MHalteres, stem pale, knob brownish. 
Legs: coxee and trochanters yellow; femora brownish-yellow, the 
extreme tip dark brown; tibiz yellowish-brown, extreme tip indis- 
tinctly darker; tarsi brown. Wings hyaline or nearly so, cells C and Sc 
yellow, stigma pale. Venation: Rs short, a little longer than Re»; petiole 
of cell M, long, as long as the basal deflection of R445. 
Abdomen: Tergum, segments shiny, segment 1 yellow, narrowly 
margined with brown behind; segment 2, yellow, brown on the caudal 
half, a large rounded brown spot on the lateral margin; segments 3 and 
4 mostly brown, more yellow basally, with a gradually smaller brown 
spot on the lateral margin of each of the sclerites; segments 5 and 6, 
brighter, more yellowish; segment 7 dark, almost black, margined with 
pale; hypopygium orange-yellow; sternum, yellowish. Hypopygium: 
7th tergite, short, shorter than the tergites immediately preceding; Sth
