which are not in view from above. A/lytra convex, impunc- 
tate, the basal fovea of the sutural line smaller than the 
rather large fovea of the discal impression. Abdomen not 
carinate at the base. 
Habitat. Gulf States. Not known to us. 
T. PUNCTICOLLE, Lec. Red-brown, convex. 
flead with the occiput not impressed in the middle, the 
fovee small, connected with the middle of the frontal margin 
by nearly straight grooves. Prothorax convex, longer than 
wide, widest near and before the middle line, the lateral fovez 
large, connecting sulcus deep, scarcely angulate in the middle; 
the disk finely and distinctly punctulate. A/ytra wider be- 
hind, with two large basal foveze, sutural line deep, discal line 
very short. Length 0.9 mm. 
Habitat. Arizona. Not known to us. 
T. THoRACICcUM, Lrend. Saturated yellow; form slender; 
pubescence very fine, abundant. Length, 0.9-0.95 mm. 
Plate XI., Fig. 95. 
flead narrower than the prothorax, one-fifth wider than 
long, tempora convergent, eyes not prominent, base impressed 
in the middle, frontal margin straight, a little more than half 
as wide as the width across the eyes; the fovez are in a line 
with the middle of the eye, mutually less than twice as distant 
as either from the eye, circumambient sulcus distinct, shallow, 
antennal tubercles small. Antenne one-half longer than the 
head, the two basal joints not as strong as in 7. parvulum; 
eighth to tenth equal in length, each twice as wide as the 
preceding one, the last one-fourth longer than its width and 
twice as wide as the tenth, ovate. The last palpal joint in 
outline securiform, but not compressed. Prothorax as long 
as wide, seemingly longer, equal to one and one-half times 
the length of the head, widest before the middle, sides evenly 
arcuate, not perceptibly sinuate near the rather small lateral 
foveee which are connected with the small medial basal fovea 
by a straight sulcus one-fourth the length of the prothorax 
from the base; disk evenly convex, finely and densely punc-
