pubescence very fine, pruinose. Length, 1.9-2.0 mm. Plate 
VIl., Fig. 51 2. 
lead, eyes excluded, nearly quadrate or slightly wider 
behind, fovea isolated, large, variolate, frontal margin wavy, 
slightly concave. Antenne half as long as the entire body, 
first to eighth joints subequal, obconical, the first one-third as 
long as the frontal margin and half as wide as long. The 
eighth is nearly quadrate, ninth to eleventh gradually wider, 
ninth and tenth obconical, as long as the three preceding 
joints, eleventh ovoid-acute, as long as the eighth and ninth 
together. Pyrothorax as broad and as long as the head, 
including the eyes, widest at middle, not very convex, fovez 
large and in full view from above. /ytra not very convex, 
sutural length much less than the humeral width, shoulders 
high, prominent. Across the tip the width is one-fifth greater 
than the sutural length. Suboral lines deep, straight, discal 
lines fine, arcuate, deeper near the base. Abdomen rather 
long, sides parallel, basal dorsal segment three times as wide 
as long, the obsolete carine including a space equal to the 
length of the segment, without sculpture in the ¢. ¢ abdomen 
with three modified dorsal segments, the first much depressed 
at the lateral basal angles. Next to the margin on each side 
is a large ovoid tumor. This gives the tip the appearance of 
being bilobed, The second segment is depressed at the sides 
of the base and in the middle is a deep, circular, punctured 
fovea. The third is produced, emarginate laterally, bilobed 
in the middle at the base, transversely depressed; the fourth 
is of nearly the same form, the two middle lobes, however, 
being united into one. Legs and under surface without 
sexual peculiarities. Antenne of ¢ longer than in 9. There 
is some variation in the sculpture of the first dorsal segment. 
Habitat. Atlantic States.
