PSELLIOPHORA COMPEDITA Wiedemann. 

 Ctenophora compedita Wiedemann, Dipt, exot., vol. 1, 1821, p. 21. 



One male, one broken female, Depok, Java, March, 1909 (Bryant 

 and Palmer). The wing is shown in plate 45, fig. 32. 



PSELLIOPHORA RUBRA Osten Sacken. 



Pselliophora rubra Osten Sacken, Berlin. Entom. Zeitschr., vol 30, 1886, p. 171. 



Buitenzorg, Java, male, April 4, 1909; female, March, 1909 (Bryant 

 and Palmer), The material offers the following measurements: 



Male. — Length, 13 mm.; wing, 11 mm. 



Female. — Length, 16 mm.; wing, 12.5 mm. The species having 

 never been figured, is shown in plate 45, fig. 33. This material agrees 

 very well with Osten Sacken's brief description of this form. His 

 type, in the British Museum, came from Mouhot, Laos. In my 

 material the black color includes only segments 7 and 8 of the abdo- 

 men, 9 being reddish orange like the base of the abdomen; front 

 brown, not blackish, etc. 



Tribe TIPTTLINI. 



The question concerning the various groups of species that make 

 up the Tipulini should be again considered. The three genera, 

 Tipula Linnaeus, Holorusla Loew, and Ctenacroscelis Enderlein, are 

 all very closely related to one another and the slight differences that 

 are offered for their separation are scarcely equivalent to those that 

 distinguish genera in the Limnobinoe. 



Holorusia Loew^ has the cell ^3 of the wings very narrow at its 

 middle so that the cell is broad at both ends and shaped somewhat 

 like an hourglass; the antennae are entirely without bristle-Uke hairs; 

 femora with a semi-ctenidium of stout hairs at its tip. All of the 

 species known to me are American (grandis Bergroth (Western U. 

 S.) the genotype; maya Alexander (Guatemala); Jiavicornis Alex- 

 ander (Venezuela) ; peruviana Alexander (Peru) ; oropMla Alexander 

 (Colombia); laevis Alexander (Paraguay), etc). 



Ctenacroscelis Enderlein- has the cell R^ of the wings very narrow 

 as in Holorusia; the antennae with scattered hairs; the femora with 

 a ctenidium near the tip. All of the species known to me are Old 

 World forms {praepotens Wiedemann (East Indies, Japan); mono- 

 chrous Wiedemann (Java) ; umhrinus Wiedemann (East Indies) ; con- 

 spicabilis Skuse (Australia); dolirnianus Enderlein (Sumatra), the 

 genotype; silcMmensis Enderlein (India); rex Alexander (Burma), 

 etc.).
