The Utility of this modification in a family in which the mouth- 
parts are otherwise quite constant is, for me, beyond explanation. 
The Eucnemida 3 seem to live their short lives by the ingestion of 
liquid food, the juices of decaying wood and similar matters, so that 
this modification may assist capillary action, although there does not 
seem any reason why Cladus should be so provided and the closely- 
allied Fornax not. 
PAL,.«OXEi\lJS u. g. 
This new generic name is suggested for a species described by me 
some years ago as Cryptosto^na Dohrnii. 
At that time I had seen no specimen of Cryptostoma, and the 
failure to record several important characters in the Bonvouloir de- 
scription caused me to refer my specimen to that genus. Through 
the kindness of Mr. Ed. Fleutiaux I have been enabled to study a 
specimen of C. spmicorne, and can now indicate the differences : 
Paheoxenns . — Antennfe simple in both sexes, the last two joints 
shorter, the terminal joint broader than long, squarely truncate, but 
chisel-shaped on its terminal edge. Mesosternum oblique, broadly 
grooved. Eyes longer in their vertical diameter and without dis- 
tinct supra-orbital ridge. 
Cryptostoma . — Antennse with a spiniform process from the base of 
third joint % , or with a spine on the posterior side near apex of 
first joint 9 , the terminal joint longer than the preceding and either 
slender % , or very acutely oval at tip 9 . Mesosternum prominent, 
the sides elevated, forming the usual receptacle for the tip of proster- 
num. Eyes oval, very little longer vertically and with distinct 
supra-orbital ridge. 
PHEXGODES Latr. 
I*. |»icicollis n. sp. — Head piceous black, deeply, arcuately impressed be- 
tween the eyes, and longitudinally toward the clypeus, in front of the transverse 
groove coarsely and closely punctate, behind it coarsely longitudinally strigose 
and punctate; antennie not half as long as the body, piceous-black. the branches 
fuscous, the basal joint yellow: eyes relatively small ; thorax about one-half 
wider than long, apex arcuate, sides arcuate near the front, then parallel to base, 
lateral explanate border moderate, disc moderately convex, a round fovea each 
side near the apex, a slight longitudinal impression at middle nearer the base, 
surface shining, rather finely not closely punctate, more distinctly near the sides, 
sparsely flavo-pubescent, color piceous, with the entire limb narrowly testaceous; 
scutellum piceous; elytra yellowish testaceous, gradually fuscous toward the 
apex ; abdomen yellowish testaceous, the segments piceous along their anterior 
b(!rder, beneath piceous, shining, the border and last segment pale; ineso-meta-
