22,5 Alexander: Crane Flies from Formosa and Luzon 475 



Venation : r very short, less than the tip of R x beyond it ; petiole 

 of cell R 5 a little longer than the basal section of M 1+2 . 



Abdomen dark brown, the basal sternites and the hypo- 

 pygium obscure brownish yellow. Ovipositor with the valves 

 conspicuously yellow. 



Habitat. — Formosa. 



Holotype, male, Musha, altitude about 3,500 feet (about 1,050 

 meters), August 15, 1921 (T. Esaki). Allotype, female, Su- 

 maan, altitude about 2,500 feet (about 760 meters), August 21, 

 1921 (T. Esaki). 



Trentepohlia pulchripennis is related to T. ornatipennis Bru- 

 netti, of southwestern India, and T. pictipennis Bezzi, of Luzon, 

 in the general character of the wing pattern, but is distinct 

 from any described species. 

 Trentepohlia (Mongoma) esakii sp. nov. 



Female.— Length, 9 millimeters; wing, 7.7. Allied to T. (M.) 

 pennipes (Osten Sacken) , differing as follows : Head dark gray, 

 the occiput obscure yellow. Mesonotal praescutum brown, the 

 lateral margins and humeral angles narrowly obscure yellow. 

 Legs with the femora pale brown, the tips rather narrowly 

 (1 millimeter) white; tibiae dark brown, the tips broadly white, 

 on the middle legs occupying about the distal third of the seg- 

 ment; tarsi white. The white distal third of the midtibia is 

 distinctly fringed with conspicuous white setse as in the pen- 

 nipes group. Midfemur with about nine stout spines near the 

 base, with other additional spines arranged in a row, these 

 becoming more elongate and more distant from one another 

 toward the outer end of the sclerite, the apical ones appearing 

 bristlelike. Wings whitish subhyaline; veins brown. Vena- 

 tion: Sc x about equal to R 2 ; r a little more than its length 

 before the fork of R 2+s ; R 2 gently sinuous. 



Habitat. — Formosa. 



Holotype, female, Musha, altitude about 3,500 feet (about 

 1,060 meters), August 15, 1921 (T. Esaki). 



Trentepohlia esakii is named in honor of the collector. It is 

 related to T. pennipes (Osten Sacken) and T. tarsalis Alexander 

 in the feathered midtibial apices, but is very distinct in the 

 conspicuous white femoral tips. 

 Ceratocheilus taiwanicola sp. nov. 



General coloration dark brown ; mesonotal praescutum yellow- 

 ish gray with three dark brown stripes; legs dark brown;
