Rao BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. 
the body, lying along the breast near the prosternal sutures, not well 
enough defined for description. Prothorax punctulate, finely and 
sparsely, the outline incomplete on one side but evidently the width 
is about one half greater than the median length, base and apex 
subequal, front angles obtuse, sides regularly rounding to the hind 
angles which are obscure and probably short. Scutellum oval. 
Elytra a little over three times the prothoracic length, apices con- 
jointly rounding, surface distinctly and rather deeply but finely and 
sparsely punctured without any definite strial arrangement. Under- 
side obscurely, finely punctate. Length, from front of head to elytral 
apex, 4.65 mm.; of elytron, 3.25 mm. 
Described from one specimen, with counterpart. 
Type— In the Museum of the University of Colorado. It was 
collected at Station 14, Florissant, Colo., by Dr. W. M. Wheeler, 
while a member of one of Professor Cockerell’s expeditions. 
Probably not a true Paranomus, but I can find no better place for 
it and the assemblage of visible characters points in that direction. 
The metacoxal plates are not suddenly dilated, the prosternal lobe 
is moderate, the sutures nearly straight, apparently slightly excavate 
anteriorly, the elytra not striate. The size is somewhat less than that 
of the recent P. estriatus, from Mt. Washington. 
LUDIOPHANES, gen. nov. 
Form of Ludius. Elytra confusedly punctate, not striate. Coxal 
plates gradually narrowed externally and not toothed over the inser- 
tion of the thighs. Scutellum ogival.

Plate 4, fig. 7-9. 
Form moderately elongate, tapering a little to both ends. Head 
short, closely, deeply, and coarsely punctured, except on the extreme 
frontal region where the sculpture is more shallow. Antennae very 
slightly longer than the prothoracic median line but not reaching the 
tips of the hind angles, eleven jointed, feebly serrate, first joint large, 
second shorter than the third, third and fourth subequal in length,
