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 Tipulidae. " 



Pachyrhina nigroltilea Bellardi. 



Macromastix chilensis Philippi. 



Tipula albifasciala Macquart. 



Tipula craveri Bellardi. 



Tipula edwardsi Bellardi. 



Tipula microcephala v. d. Wulp (which seems to belong to Holorusia Lw.). 



This name is preoccupied by 7". microcephala Big. (1858) , and I rename the 



South American species, Tipula 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 macrostema, sp. n. 



Thoracic stripes not complete, represented, when at all evident, 

 only by spots at the margins of the prasscutum ; dorsal apical appendage 

 of the d^ genitalia prolonged, stylet-like. 



cf Length, 10.3—10.8 mm.; wing, 11.4— 11. S mm. 

 Middle leg, femtir, 8 mm. ; tibia, 8.9 mm.

cf Head: Anterior prolongation of the front brownish-yellow, 

 clearer yellow beneath and on the sides ; palpi browaiish ; anteima;, 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; tenninal three or four segments uniform 

 browTi. Front, vertex and occiput yellow, more browTiish in the middle 

 of the vertex, very broadly shiny, this mark not clearly delimited but

Abdomen: Tergtun, segments shiny, segment 1 yellow, narrowly
