between the clypeus and the eye. The yellow 
colouring does not extend as far backwards on the 
head as to the base of the antennse. The front side 
of the front tibise is yellow ; the tarsi are testaceous 
at the base, becoming fuscous towards the apex; the 
. rest of the insect is black. I find no very noticeable 
difference between this species and facilis^ Sm. in 
respect of punctuation except that the head is rather 
more roughly punctured behind the antennae. The 
head is very short, the distance from eye to eye 
across the front of the base of the antennae being 
very considerably greater than from the base of the 
antennae to the base of the clypeus. The portion of 
the head behind the antennae is tumid, so that the 
ocelli seem to be placed on a rounded swelling. The 
apex of the clypeus is rounded. The underside of the 
hind body is sparingly and not strongly punctured. 
The basal joint of the antennae is rather strongly 
dilated in the male, its length being hardly twice 
its width. 
A single specimen occurred on Mauna Kea, Hawaii, at an 
elevation of about 7,000 feet, in February. A female 
taken in the same neighbourhood probably belongs 
to this species, as its head is similarly formed, though 
it is less roughly punctured. It is quite black, except 
the legs which are dark pitchy, and the wings are 
much clouded with fuscous.
