THE PsELAPHIDZ OF NORTH AMERICA. 247 
T. minor, Lec. Black, polished, convex, coarsely pubes- 
cent; antenne, palpi, frontal tubercles, legs, and fourth and 
fifth abdominal segments reddish brown. Length, 1.4 mm. 
Plate VII., Fig. 27. 
ffead polished, as long as broad, tempora as long as the 
eyes, frontal tubercles transverse, incision conspicuous. Nearer 
to the frontal tubercles than to the eyes on each side is an 
acute tubercle pointing outward, behind which is a punctiform 
impression. Occiput higher than in 7. /ongipalpus, longitu- 
dinally plane, transversely convex. Pa/fz with the third joint 
triangular, the sides enclosing the free and tufted angle equal, 
shorter than the third, which is more than half the length of 
the last joint. This joint is securiform, shortly pedunculate, 
more than half as long as the head, broadest in the middle. 
Antenne slightly longer than the head and prothorax, the two 
basal joints more robust; the first obconical, flattened above, 
the second smaller. Joints three to seven are only about half 
as wide as the preceding, cylindrical, very little longer than 
wide, eighth globular, ninth and tenth subglobular, slightly 
transverse, eleventh twice as thick as the ninth, rounded ovate, 
and as long as the two preceding. Prothorax polished, wider 
than long, and as long as the head, widest slightly before the 
middle, where it is strongly arcuate; anteriorly and poster- 
iorly it is nearly straight, slightly sinuate, disk very convex, 
the base twice as wide as the neck. Lateral fovee rather 
large, basal foveee five in number, placed in a transverse row 
very near the base, the middle one larger, along the sides 
anterior to the lateral foveze almost imperceptibly impressed, 
the impression visible only in a certain light. Adlytra faintly 
reticulate, as wide across the shoulders as the prothorax, and, 
near the tip, two-thirds wider. Shoulders elevated, not prom- 
inent laterally, disk convex both ways, sutural lines fine, not 
deeply impressed except near the base; interval flat. The 
basal and discal lines each originate in a fovea, the latter 
deep, reaching beyond the middle. The declivous lateral 
portion of the elytra is very broad, polished, impunctate.
