9 •• — Black : front coriaceous, convex, with a short, distinct, longitudinal carina 
V above the antennae : the anterior ocellus situated in a rather deej) ])it, from which 
originates a strong impressed line, which extends down to the frontal carina: 
clypeus with a slight mesial tooth : space between the eyes at the vertex equal to 
the length of the first, seconil and third joints of the flatrellum united, beneath is 
equal to the length of the second and third joints of the antennae united ; an- 
tennae clavate, second joint of the flagellum more than half as long as the pre- 
ceding joint, the apical joint nearly as long as the two ]ireceding ones united : 
mandibles reddish ; verte.x finely i)unctured ; from the emargination of the eyes 
downwards, the cheeks, suture between collar and dorsuliim, sides of thorax and 
the metathorax, posteriorly, with bright silvery pubescence. Thorax finely 
punctured, the dorsulum shining, with a short, oblique, deep, impressed line on 
each side near the tegulfe ; scutellum not impressed medially, shining: meta- 
notum with a shield-shaped, somewhat elevated disc, which covers almost its 
entire surface, the disc finely and transversely striated, sulcate medially, the 
])osterior face of metathorax with a medial sulcns, which is much deeper at the 
base, subrugoso-striate : wings hyaline throughout, the stigma and nervures 
brownish, except at base, where, together with the tegulse, they are yellowish. 
Legs black, the tarsi fuscous, the tibial spurs slightly whitish. Abdomen smooth, 
the base of the second to fifth segment with sericeous pile: first and second 
segments of nearly equal length, the first tlie longest. Length .25 inch. 
Dift’ei's from the 9 tl'© antennje being very strongly thickened from 
the ninth joint, the apical one being acute at tip and as long as the four ])ieced-

with the tarsi slightly marked with whitish. Length .25 inch.

tennie: the anterior ocellus situated in a slight jut, the vertex excavated or de- 
pressed behind the ])osterior ocelli: clypeus rather broadly produced medially, 
the production somewhat incurved: antennae not clavate, tiie first joint of the 
flagellum about one-third longer than the second one: face, clypeus, cheeks, 
thorax on the sides and beneath, with silvery pubescence. Thorax very finely 
punctured: collar with a transverse sulcus : dorsulum without lateral impressed
