76 FAUNA HAWAIIENSIS 



base of the costa, the tips of the first, second and third longitudinal veins, the origins of 

 the second and third veins, and on the first vein opposite the origin of the third ; second 

 and third sections of the costa sub-equal, last section of the second vein twice as long as 

 the first and second sections of the third which are equal ; last section of the third vein 

 distinctly curved upwards. 



Hab. Hawaii. — Lanai. — Maui. — Oahu. 



This remarkably coloured species is said to be a native of Africa, but is also 

 recorded from Cuba, St Vincent, and Brazil. It is represented in the collection before 

 me by thirty-seven specimens, including both sexes, of which twenty-nine are from 

 Mauna Loa, Hawaii, obtained at a height of 3500 ft. in June 1892. The remaining 

 eight examples are from Kona, Hawaii (4000 ft., September 1892) ; Kilauea, Hawaii, 

 December 1896; lao Valley, West Maui Mts., March 1894 ; Lanai, 2000 ft., February 

 1894; and Kawailoa Gulch, Oahu, April 1893. Osten-Sacken and Williston both place 

 this species in the genus Borborns. On account of the extreme tenuity of the last 

 section of the third vein (rendering it almost invisible), the length of the arista and 

 nature of the face, it seems to me to be a true Limosina. 



(2) Limosma aequalis, sp. no v. 



$ $. Long. Corp. 2\ mm. ; al. 2 mm. Front deep black, with the orbits and a 

 central stripe somewhat lighter, face black, rather shining, with a double groove 

 down the centre, proboscis, palpi and antennae entirely black, the latter porrect, 

 with the third joint large, hairy and hemispherical, arista pubescent. Thorax and 

 scutellum shining black, pleurae dull black. Abdomen black. Legs black, bases of the 

 femora and the tarsi a little lighter. Wings greyish, the three sections of the costa 

 equal in length, the first section with a few longer bristles, first two sections of the third 

 vein equal, together shorter than the last section of the second vein, last section of the 

 third vein straight, terminating at the tip of the wing. 



Hab. Oahu, Kawailoa Gulch, one male and one female, April 1893. 



Closely allied to L. pnniila, Williston, from the island of St Vincent, but differs in 

 the entirely black front and face. 



Note : — Half-a-dozen specimens of Acalyptrate Muscidae, gummed on card and in 

 bad condition, have been left undetermined. 



Fam. PHORIDAE. 



Phora Latreille.

A single specimen belonging to this genus, but without head, is in the present 

 collection, from Kona, Hawaii, taken at a height of 2000 ft. in September 1892,
