338 FAUNA HAUAIIENSIS 



series of specimens may prove that E. fiavo-orbitalis is only a variety of E. mac2tlipennis. 

 (Cameron.) 



$. Length 9 to i6 mm. Differs from female of E. viaculipennis in having the 

 scape of the antennae, the apex of the clypeus, the anterior and middle legs, except 

 coxae, and the abdominal segments 7 to 8 rufous. 



Hab. Hawaii : Hilo in July (H. W. Henshaw). — Molokai, in mountains (4500 to 

 5000 feet), in June (Perkins).

( 1 ) Glyptogastra haiuaiiensis, sp. nov. 



$, ^. Length 7 to 13 mm. Entirely black, except that the anterior femora and 

 tibiae beneath are ferruginous. The head and thorax are coriaceous and finely punctate; 

 ocelli transparent, pale amber coloured ; wings smoky black, with a faint violaceous tinge 

 in certain lights. The head is transverse, with the temples very flat, not developed, the 

 face above the insertion of the antennae concave, with some fine transverse striae in the 

 basin. The clypeus is distinctly separated from the face, nearly smooth, subopaque, 

 with a few punctures toward the base, the anterior margin being slightly arcuate, not 

 impressed. The antennae are nearly as long as the body, in female 31-jointed, in male 

 32-jointed, the first joint of the flagellum being much the longest, nearly eight times as 

 long as thick, the following to the last gradually shortening, the last joint about twice as 

 long as the antepenultimate. The scutellum and the postscutellum have deep, broad 

 furrows at the sides, the former being connected with the mesonotum by strong, elevated 

 carinae at the sides anteriorly and has a furrow or depression across the base. The 

 metathorax has a shallow median furrow which broadens into a triangular depression at 

 apex, the triangular space thus formed with some faint, oblique lines. The abdomen is 

 elongate, shaped as in Pimpla, the surface finely, microscopically reticulated, the first 

 segment with a hump-like elevation at its apical third, segments 2 to 5 with oblique 

 impressed lines laterally, and segments 2 to 4 with also indications of a transverse line 

 at or near their apices, the line more distinctly impressed laterally. Ovipositor promi- 

 nent, about half the length of the abdomen. The venation of the wings is similar to 

 Echthromorpha, only the discoidal nervure is not quite interstitial with the median vein. 



Hab. Hawaii : Kilauea, in August ; Kona (4000 feet), in September.
