the recent M. aterrimus of the Pacific states. I am not sure of the 
antennal structure, but it looks as if the second and third joimts are 
very short and what can dimly be seen of the hind coxal plate on one 
side has the appearance of being broad internally and much narrowed 
to the outer edge. Of course the generic reference is subject to 
correction in the event of more material coming to hand. 
CRYPTAGRIOTES, gen. nov. 
Body form almost like that of Cryptohypnus. Coxal plates nearly 
linear, scarcely narrowed externally, obtusely lobed over the thighs. 
Prosternum short with a small, subtruncate lobe, sutures nearly 
straight, apparently excavate anteriorly. 
Type.— C. minusculus, sp. nov. 
CRYPTAGRIOTES MINUSCULUS, sp. nov. 
Plate 4, fig. 3. 
Form moderately stout. Head large. Antennae not well pre- 
served, slender, reaching beyond the prothoracic hind angles. Pro- 
thorax probably somewhat distorted, but, as preserved, wider in 
front of the middle where the width is a little greater than the length. 
Sides very gently arcuate, angles not well shown. Prosternal sutures 
nearly straight, lobe rather short, entire under surface of the prothorax 
finely punctulate and pubescent. Elytra two and one fourth times 
the prothoracic length, conjointly rounded apically, the sides some- 
what arcuate, sculpture not showing through. Abdomen very finely 
punctulate and pubescent. Length, from front of head to elytral 
apex, 4.00 mm.; of elytron, about 2.30 mm. 
Described from one specimen. 
Type.— No. 2,749 M. C. Z. Florissant, Colo. (No. 8,653 S. H. 
Seudder Coll.). 
Judging from the form of the coxal plates, this little beetle should 
go into the Corymbitini, possibly near Agriotes, but it does not agree 
with any genus known to me.
