[December 
is represented in anterior % of elytral length by a series 
of coarse, subconfluent punctures. Disc of elytra otherwise 
shining and impunctate, except that on the left elytron there 
are three and on the right two setigerous (the bristles can 
be detected in three of the five punctures, and are broken 
off in the other two) punctures in a position corresponding 
to the 4th interval in striate Maronetus. Subapital mar- 
ginal setigerus punctures of elytra nearly obliterated, only 
one or two very small ones being visible on each elytron. 
Epipleurse and under surface of body shining, impunc- 
tate except for the usual orderly series of setigerous punc- 
tures. 
Tarsi and palpi of $ unknown; those of $ normal for 
Maronetus.

Type: $ , Museum of Comparative Zoology, No. 16431, 
from Highlands, N. C., June, 1888. In the Frederick Blan- 
chard Collection, probably collected by Blanchard himself. 
Nomaretus unistriatus is unique in the great reduction 
of the elytral striation, and probably also in the reduction 
of the marginal setigerous punctures near the apex of the 
elytra. Blanchard’s specimen (my type) has been men- 
tioned by Leng (1916, p. 42) as probably representing an 
undescribed species, but Leng did not describe it, because 
he was unable to determine the amount of variation nor- 
mally occurring in species of Maronetus. Fortunately the 
series of over 50 specimens of M. schwarzi before me shows 
pretty conclusively that such variation is not extreme, so 
that I feel sure that unistriatus is a real species, not an 
individual variant of some striate form. In addition to 
the unique characters by which it may be recognized at a 
glance, unistriatus differs from schwarzi in having the dor- 
sal surface not microreticulate, and from imperfectus 
(probably its closest relative) in having setigerous punc- 
tures on the elytra in a position corresponding to the 4th 
interval in the striate species.
