As seen from above the head is l>ut slightly narrowed behind the eyes, rather 
distinctly truncate caudad, the occiput margined; from in front the eyes appear 
very prominent and bead-like, reaching the base of the mandibles, and con- 
verging below; from a lateral view the cephalic surface of the head is nearly 
plane, the temples about as wide as the posterior ocellus; the eyes appear 
black polished, the facets not \isible under a low power; the vertex, occiput, 
temples, and gular regions are black, moderately coarsely but sparsely punc- 
tate, the punctures bearing both erect, white and short, sparse, decumbent 
hairs; the ocelli are large and prominent, the posterior pair slightly larger than 
the anterior one, placed slightly nearer to the compound eyes than to each 
other, the vertex between the three forming a raised triangular area; there is 
a groove extending from the anterior ocellus to between the antennae, which 
are approximate, almost attingent, their bases sheathed each by a scale-like 
projection of the frons; elevation of the latter higher than that of the face; 
clypeus and face not separated, together convex, coarsely jiunctured, the apex 
rather deeply emarginate, beneath which the labrum is apparent, fringed with 
long white hairs; face, including the projections of the frons at the base of the 
antennae, the labrum, and the bases of the mandibles, testaceous; a portion 
of the face laterad of the convex central part is plane smooth and impunctate; 
just below the antennae it is noticeably depressed; mandibles rather long, 
slender, evenly curved, with a single blunt tooth within, dark toward their 
apices; mouthparts testaceous, the second segment of the apparently four- 
segmented labial palpi wide and flattened. Antenna filiform, yellow, the 
scape paler than the rest, bearing white hairs, the flagellum naked except for 
a very fine, close and short puberulence; scape and pedicel together a little 
shorter than the following segment, the pedicel on its outer (longest) side about 
one-third the length of the following segment, much less within; no distinct 
area differentiated from the rest at the base of the first flagellar segment, such 
as is noticeable in some species. 
Pronotum dorsally and laterally coarsely but not closely punctured, with 
erect and a small quantity of inconspicuous decumbent pubescence; propleura 
mostly smooth, with only a few scattered hairs, except for a consi)icuous l)rush 
of straight, closely set, white hairs in front of each coxa; mesonotum andscu- 
tellum sculptured very much like the head and pronotum, the lateral lines 
almost obliterated; scutellum with its white hairs longer than on the meso- 
notum, moderately trimcate, its sides weakly margined anteriorly; post- 
scutellum convex and prominent; pleura more closely and roughly punctured 
than the dorsum, the vestiture similar; mesosternum produced on each side 
in front of the middle coxae into a sharj) tooth jjointing caudo-ventrad, the 
two connected by a weak ridge, from which a weak median carina projects 
caudad on the metaventer, on the latter, in front of each j)Osterior coxa, a 
long flattened mammiliform process, projecting due ventrad; iiropodeum 
strongly and coarsely reticulate, the reticulations smaller on the sides. 
\\'ings milky, with a fuscous sj)ot along the costal margin beyoml the vena- 
tion; the veins and stigma weak and flavous; C ami Sc + R -|- M each with 
a double row of stout, rather long hairs, tlie two rows more or less merged on C
