INSECTS OF SAMOA. 



7. Homoneura (Homoneura) hawaiiensis Mallocli. 



Distinguishable at once from any other species represented in the collection 

 before me owing to the thorax being densely covered with grey dust. As its 

 name implies, the present species was originally described from material from 

 Hawaii, where, so far as my existing knowledge goes, there is only one other 

 representative of the genus. 



Tutuila : Pago Pago, 14.xii.l925. Upolu : Apia, 18.ii.l924 (Buxton and 

 Hopkins), and 27.V.1924 (Bryan). Savaii : Safune, 5.V.1924 (Bryan). Manua : 

 Tau, 20.ii.l926 (Judd). 



I have seen examples of this species from no other localities than Samoa 

 and Hawaii.

 cheeks, antennae, trochanters, tibiae, and tarsi, testaceous yellow ; palpi, 

 antennae, and face, sometimes brown or fuscous. Wings greyish-hyaline, not 

 blackened at bases. Calyptrae and knobs of halteres fuscous.

 entiated, orbital bristles moderately strong, anterior pair a little shorter than 

 posterior pair, ocellars and postverticals shorter than anterior orbitals, sub- 

 equal, outer verticals over half as long as inner pair ; longest hairs on arista 

 about equal in length to its basal diameter ; third antennal segment over 1-5 

 as long as wide ; face shining. Thorax with usual three pairs of postsutural 

 dorsocentral bristles ; intradorsocentral hairs in about ten series, and at least 

 one pair of outstanding acrostichal bristles about midway between suture and 

 hind pair ; sternopleurals 2. Abdomen ovate ; male hypopygium as in text- 

 fig. 3. Fore femur with series of short setulae on apical half of antero ventral 

 surface quite well developed ; middle tibia without posterior bristles ; liind 

 femur without an anteroventral preapical bristle ; preapical dorsal bristle
