branches as well as areas between the veins marked by papilla- 
like projections; base of anterior wing twice the width of base 
of posterior wing; forewing with radius sector and median sep- 
arate at base; radius sector sends five distinct branches, and 
one or more small branches to the costa; median joins radius 
sector beyond middle of wing usually near to origin of third 
branch of radius sector ; cubitus with eleven to thirteen 
branches; hind wing with six or seven branches uniting radius 
sector and costa, inner three large; median and radius sector 
usually united for a short distance at their bases; median joins 
radius sector distally between points of origin of second and 
third branches of latter (in one specimen median runs to end of 
wing!) ; cubitus with about eleven branches which tend to be 
more subdivided than those of forewing; cubitus of both wings 
bends slightly toward radius sector near level of junction of 
median and radius sector; a few indefinite cross veins unite 
cubitus and radius sector beyond junction of latter with median.

Soldier . — Mandibles and anterior region of the head black 
shading into a dull purplish on posterior portion of the head 
and lateral cervical sclerites; antennae, palpi, and distal por- 
tions of the legs light yellow, body segments and proximal 
portions of legs pale purplish brown. Head directed ventrally 
and nearly at right angles to body, short, thick and high, 
broadest anteriorly, suggesting the head of a bulldog (hence the 
specific name) ; anterior surface deeply excavated and extensively 
roughened and sculptured; lateral and dorsal margins of this 
frontal area produced to form a very marked, outwardly and 
forwardly directed flange, deeply notched in the midline, giv- 
ing the head the bilobed appearance characteristic of the 
genus; below, this flange runs laterally on either side to form 
the anteriorly extended posterodorsal margin of the antennal 
foveola, being separated by a groove from the anterodorsal and 
anterior margins of the foveola which form an anteriorly pro- 
jecting, laterally flattened, scalelike spine, whose upper portion
