July, 1918.) Type No. 1005. I name this species after the ill- 

 fated naturalist of the Astrolabe who lost his life at Tutuila 

 in 1788. 



Austroloma baumanensis sp. n. Figs. 7, 7a. 



Male. Length 2.6 mm., tegmen 3.8 mm. In the tegmina MS + i 

 bent at nearly right angle, forcing the apical portions of Cul and Cula * 

 together. * 



Medio-ventral edge of pygofer produced into a small process, lateral 

 edges roundly produced; anal segment short and broad, apex slightly 

 rounded, broad, with a short, angular projection near each corner, anus 

 slightly distad of middle; genital styles flat, slightly curved, slightly 

 broadest at apex, which is subtruncate and slightly oblique; aedeagus 

 large and complex, basal two-thirds tubular, flexed at one-third from 

 apex, a small spine just basad of the joint, apex with a strong, curved 

 spine at the apex of which the functional oriflce ajjpears to be situated ; 

 basad of this there is a membraneous lobe on each side. 



Light brown, outer angles of mesothorax laterad of outer carinae 

 dark brown ; a series of small, brown spots on temples and sides of 

 clypeus; legs with small brown bands; abdomen yellow or light brown, 

 pygofer dark. Tegmina hyaline, fuscous at base, in middle of cla^iis, 

 from stigma to middle of tegmen, over cross veins spreading out to 

 apex; veins mostly lighter with brown tubercles. 



Female. Length 2.7 mm., tegmen 4.2 mm. Ovipositor not projecting 

 beyond apex of abdomen; inclined to be darker than the males, especially 

 the abdomen, which is brown. 



Described from twenty-six males and thirty-seven females 

 from Tutuila, from 700 to 1200 feet elevation. (Kellers, April 

 to December, 1918. ) Type No. 1006. This insect is named 

 after the islands called Bauman islands by Roggewein in 1721, 

 and supposed to be the same as the Samoan islands. 



Austroloma wilkesi. sp. n. Fig. IG. 



This species differs from A. iaumanensis in being uniformly light 

 !)rown \vith no dark marks on legs, few or no dark tubercles on tegmina 

 and the lateral portions of mesonotum not darker than middle. 



The male genitalia are very distinct. There is no projection from 

 the edge of the anal segment and the genital styles are not quite 

 so curved. From the apex arises on the right side a long, sinuate 

 process nearly as long as the aedeagus, from the left side of apex a 

 thin, wider process with a small spine near base and a larger one about 



* I agree with Tillyard in considering Cu2 as forming the claval 

 suture.
