new Species of Pedaria. 
The head is evenly and rather strongly punctured, with 
much less distinct punctuation on the clypeus ; the clypeus 
has the angles of the emargination distinctly but slightly 
dentiform ; halfway between this angle and the posterior 
angle there is a very slight sinuosity. The thorax is evenly 
convex, without any swelling in front, a little constricted at 
the base, arcuately narrowed at the anterior angles, evenly 
and strongly punctured ; at halfway towards the side about 
seventeen punctures may be counted in a line from the front 
to the posterior margin ; the punctures are deep, separated 
from each other by about one half the diameter of a puncture. 
The elytra have the striae rather fine, with the punctures in 
them not very close together ; the first interstice is rather 
closely punctured, the second is irregularly punctured for the 
basal half and then (like the other interstices) has two lines ; 
these punctures are rather small, and leave a rather wide 
smooth space in the middle of the interstice ; below the 
shoulder there is a line of about five small shining tubercles, 
and on the ninth interstice a longer line of more distant 
tubercles ; these tubercles are visible when viewing the insect 
from above, 
Aphengium. 
I have just had an opportunity of examining the type of 
Aphengium seminudum , Bates (Biol. Centr.-Amer., Coleopt. 
ii. 2, p. 42), and it appears to have been placed in this genus 
by an oversight. In characterizing the genus Harold says, 
u Tarsorum posticorum articulus primus sequenti longitudine 
multo longior ; pygidium rectum. Segmenta abdominalia 
connexa” (Col. Hefte, iii. p. 54). A . seminudum has the 
abdominal segments free ; the pygidium is completely turned 
under, so that its apex is directed forwards, and Mr. Bates 
observes, u The short and broad, compressed and subtrian- 
gular tarsal joints are a remarkable distinguishing feature. 
The anterior cavity of the prosternum is exceedingly deep.” 
These characters appear to me to conform more with Bdelyrus, 
Harold (Col. Hefte, v. p. 97), of which Harold says : 66 Clypeo 
antice angustato et breviter bidentato. Prosternum antice 
profundissime foveolatum. Segmenta abdominalia suturis 
distinctis. Pygidium contractum et abdomini appositum. 
Tarsi postici dilatati, compressi, articulis latitudine sensim 
decrescentibus.” The clypeus has a projection in the 
middle, and in fresh specimens this is slightly bidentate ; 
this seems to agree with Harold’s character.
