piloso, alls hyalinis infuscatis ; ahclomine nitido, in medio 
latOy vix evidenter punctato. 
Long. 9 mm. 
The yellow markings are as follows : — The basal two 
thirds of the upper surface of the mandibles, the' 
anterior face of the basal joint of the antennae, the 
sides of the prothorax and a spot near the tegulae, 
the post scutellum, an interrupted band on the second 
dorsal segment of the hind body, a band on the 
fourth segment, and a spot on the fifth. The eyes 
are moderately facetted and not strongly separated 
(as compared with other species), and the forehead 
is strongly concave. The head is closely, finely, and 
smoothly punctate. The punctuation of the meso- 
thorax is obscure, that of the scutellum and meta- 
thorax extremely fine, these parts, being, however, 
rather strongly strigose longitudinally. The pubes- 
cence is whitish, but there is not much of it in my 
specimen, which is possibly abraded. 
Though this insect is closely allied to G. affinis, Smith, 
the much smoother punctuation of the head, on 
which there is no distinct strigosity, the evidently 
coarser facets of the eyes, and the more strongly 
concave forehead indicate, I think, that it is a 
distinct species. 
A single female occurred on Maui, near Wailuku, flying 
over flowers.

Crahro distinctus, Smith, Cat. of Hymen., IV., p. 422. 
This seems to be different from any of the species 
described by Mr. Blackburn. The following is 
Smith’s description (P.C.) : — 
Female; length three lines ; black; the head and thorax 
opaque; the stemmata in a curve on the vertex; 
the face canaliculated ; the inner orbit of the eye
