New Mordellidae and Notes. 
By John B, Smith. 
Among the material recently sent me for determination in this 
group were several new species, and several varieties from localities from 
which they had not been previously recorded; proving thus that the 
species are very widely distributed. 
Mordellistena erratica sp. nov. . 
Posterior tibia with a single, very oblique ridge, first joint of 
posterior tarsi also with a single oblique ridge. Color entirely black: 
cuneate; anal style short and truncate. 2mm. Fla. 
A single specimen in my collection: this species is curious and 
interesting by the structure of the posterior tibiae and tarsi: the subapical 
ridge of the tibia is indistinct, and the other ridge very strongly marked 
is very like that on the posterior tibia of Glzpodes; the carina along the 
dorsal line is wanting however, and the palpi differ from that of the 
species of the latter genus, This species should head the list of those 
placed in this genus. ‘ 
Mordellistena tarsalis sp. nov. 
Posterior tibia with a single strongly marked oblique ridge en- 
tirely crossing the outer face, subapical strongly marked; first joint of 
posterior tarsi with /wo oblique ridges, Form stout, cuneate: black; 
mouth, margins of thorax and a broad vitta on elytra orange yellow: legs _. 
except posterior tibia pale. 1% mm. Texas. 
A single specimen in my collection. This species connects the 
preceeding with the others of this genus and it should follow immediately 
after it in the list. 
Mordellistena pratensis sp. nov. 
Posterior tibia and first and second joints of posterior tarsi each 
with two short oblique ridges: all distinctly marked. Body black, elytra — 
golden yellow with fine sericeus pubescence: suture and side margins nar- 
rowly fuscous: legs all pale. Length 12 mm, Fla. 
A single specimen in my collection differing from all others in 
its group by the color of elytra: it should follow in the list immediately 
after eleganitulus. 
Mordellistena fusco-atra Hel. 
Of this species I found a single specimen among my New Jersey 
collections: it is the first specimen of the species I have seen and agrees in 
all respects with Dr. Helmuth’s description.
