tibiae and tips of the tarsal joints brown. Wings whitish hyaline, anal angle prominent, 

 transverse vein dark, rest of venation pale.

Plate I. figs. 6 and 7, wing and % antenna. 



Orthocladius V. d. Wulp. 

 ( I ) Orthocladiits, sp. 



Two females belonging to this genus, not in sufficiently good condition for 

 description, were obtained at Haleakala, Maui, 5000 ft., in March 1894. 



Tanvtarsus V. d. Wulp. 



(i) Tany tarsus lacteiclavus, sp. nov. 



^ %. Long. corp. 2 mm. ; al. if mm. 



Antennae light brown. Thorax uniform blackish-brown, halteres pale, almost 

 milky-white. Abdomen dark-brown, genitalia of t conspicuous, light yellowish. Legs 

 light brown, hairy, fore metatarsi not quite half as long again as the fore tibiae, all 

 the tibiae darker at the tip, all the metatarsi ringed with white at the base and apex, 

 remaining joints of the tarsi unicolorous. Wings hyaline and uniformly hairy. 



Hab. Kauai. Koholuamano, six males and two females (all gummed on one card),

Ceratopogon Meigen. 



(1) Ceratopogon, sp. 



Three imperfect specimens of a species belonging to this genus, two of which 

 are males, were beaten from trees, Wainae Mts., Oahu, 3000 ft., in April 1892. 

 Drawings of the wing, the apical joints of the male antennae, and the end of the fore 

 foot in the same sex, are given in Plate I. figs. 8 — 10. In the last joint of the loot 

 there represented I would draw attention to the remarkable excavation on the upper 

 side of the base, a feature which, so far as I am aware, has not hitherto been noticed 

 in members of this genus.
