longer than the petiole, which is alutaceous. The abdo- 

 men is covered (especially the apex) with a pale pube- 

 scence. Wings hyaline ; nervures and stigma pallid 

 testaceous; areolet complete, scarcely petiolated. Length, 

 5 mm., with terebra. 



Hab. Haleakala, Maui, at an elevation of about 

 4000 feet (No. 101). 



Limneria blackbumi, n. s. 

 Black ; the mandibles, palpi, trochanters, knees and 

 tibiae (except at base and apex), and spurs, yellowish 

 white ; femora and base and apex of anterior tibiae, 

 reddish ; base of four posterior femora, base and apex of 

 posterior tibial, blackish ; coxse and base of trochanters 

 black ; anterior tarsi fuscous ; the base of the tarsal 

 joints pale. Abdominal segments at junction white ; 

 ventral surface at base yellowish. Head, thorax, and 

 coxa? almost opaque, faintly punctured, covered with a 

 white pubescence, which is especially long on the face. 

 Abdomen semiopaque, very finely punctured ; terebra as

 smooth, almost shining. The three basal areolae of meta- 

 notum are less strongly punctured than the rest ; the 

 superior median areola small, distinct, semicircular, 

 broader than long ; posterior median triangular at base ; 

 from that it contracts slightly, and ends about the 

 middle of the metanotum, where there is another field 

 longer and somewhat oval in form, which occupies the 

 rest of the middle space ; the posterior intermedian area 

 is semiobsolete, small ; spiracular, large, wider at base 

 than at apex ; at the base it becomes rounded and en- 

 larged. Wings hyaline ; areolet shortly stalked ; stigma 

 fuscous. Length, 6 mm. 



Hab. Mauna Kea, Hawaii, at an elevation of at least 

 13,000 feet, on the snow near the summit. 



The metathoracic fields are much more clearly defined 

 in this species than usual.
