8o FAUNA HAWAIIENSIS 



Fam. DOLICHOPODIDAE (p. ii). 

 Gnamptopsilopus Aldrich (p. ii). 

 (i) Gnamptopsilopus pate I lifer, Thomson (p. ii). 

 An additional female from S. Kona was obtained in F"ebruary 1899. 



DoLiCHOPUs Latreille. 



This genus, not hitherto recorded from the Sandwich Islands, is represented in the 

 present collection by five specimens obtained in the island of Oahu in 1901. Three 

 males and one female are from the Waialua Mts. (May), and the other specimen, 

 a male, from N.W. Koolau (July). I have not been able to identify the species, but it 

 comes very near the European griseipennis Stann. The antennae, however, are 

 shorter, the fore coxae quite yellow, without silvery sheen, the hind tibiae dark in at 

 least their apical half, and the fourth longitudinal vein not so abruptly broken.
