the body, lying along the breast near the prosternal sutures, not well 

 enough defined for description. Prothorax punetulate, 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 elvtra 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 gradualh' 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,
