348 FAUNA HAWAIIENSIS 



(3) Enicospihis ivaiineae, sp. nov. 



$. Length 15 to 16 mm. Resembles E. niaiiicola, but smaller, the abdomen 

 slenderer, seen from the side, not so wide dorso-ventrally ; the face below the antennae 

 is obscure rufous or brownish ; the antennae and the abdomen, except segments i and 

 2, are brown ; the anterior trochanters, the second joint of the middle and hind tro- 

 chanters and all tibiae and tarsi are pale ferruginous. Otherwise it is quite similar 

 to E. mauicola, except that the blister-like spot in the disco-cubital cell is larger and of 

 a triangular or oblong-oval shape, while the enclosure at base of the metanotum is 

 punctate. 



Hab. Kauai : Mts. of Waimea (4000 feet), in June. — Hawaii : Olaa, in December. 



(4) Enicospihis variegatus, sp. nov. 



%. Length 20 to 22 mm. Brown or castaneous ; the disk of the mesonotum 

 more or less, a stripe on the scutellum, the mesosternum, the metathorax, except at 

 base above, the apical two-thirds or more of the femora and abdominal segments i and 

 2, black ; the orbits and the face are dirty white, the antennae are brown, longer than 

 the body ; while the legs, except as noted, are pale ferruginous, the last joints of the 

 tarsi being fuscous. The metathorax is without the basal transverse carina. 



Hab. Hawaii : Hilo (H. \V. Henshaw) ; Olaa, in December (Perkins). 



(5) Enicospilus nigrolineatus , sp. nov. 



?, t- Length 15 to 18 mm. Brownish-yellow, the antennae and the legs some- 

 what paler ; a median line on the mesonotum, a large spot on the mesosternum and 

 the disk of the metathorax from the basal transverse carina, and a more or less distinct 

 line on the sides of the abdomen, dark fuscous or black. 



The antennae are much longer than the body, yellowish, in both sexes, the first 

 joint of the flagellum being scarcely so long as the second and third joints united. The 

 basal transverse carina of the metathorax is distinct in both sexes, and the space 

 enclosed by it is much smoother than that beyond. The wings are hyaline, the stigma 

 and the veins, except the second abscissa of the median vein and the second abscissa 

 of the radius, which are brown, being yellowish.

 June. — Hawaii: Hilo (H. W. Henshaw), in May; Kona (4000 feet), in August,
