ment; pygidium glossy on apical half. Legs normal, hind tarsal groove 
long.

Type locality, Urbana, Ill., Sept. 6, 1891 (C. A. Hart). Six speci- 
mens. 
TIPHIA ARIDA, sp. n. 
Female—tThis species closely resembles punctata, but differs in 
having the tegulae with an incised line on a large part of outer margin, 
the basal dorsal abdominal segment with a rather shallow, broad post- 
marginal depression in which there are 2 rows of punctures centrally, 
and a large median patch of small punctures on the declivitous anterior 
half of segment, which extends caudad almost to the post-marginal de- 
pression. The incised line on posterior margin of abdominal segments 
is present only on lateral portions of segments 2 and 3 but complete on 
4 and 5. The pygidium is irregularly wrinkled and indistinctly sha- 
greened on basal portion of apical half. The hind tarsal groove is long 
and deep. Radius leaves stigma at apex of lower side, the apex of stigma 
oblique. Otherwise as punctata. 
Length, 11.5 mm. 
Type locality, Havana, Ill., Aug. 13, 1903 (C. A. Hart). Taken at 
a place called Devil’s Hole. 
TIPHIA TEXENSIS, Sp. n. 
Female Agrees in most respects with punctata, but is larger, gen- 
erally exceeding 15 mm. in length. The metathoracic enclosure is 
somewhat lyre-shaped, the lateral ridges being bent inward at middle, 
cephalad of which they are curved outward and then, just at anterior 
margin, they curve inward again. The lower part of sides of meta- 
thorax have 2-3 large punctures close to lower margin, but are otherwise 
as in punctata. The basal dorsal abdominal segment is similar to that 
of punctata, but the second is more regularly covered with larger punc- 
tures. The shagreening on pygidium is very minute and becomes obsolete 
before reaching apex. 
Type locality, Dallas, Texas. Four females. (Coll. N. Banks.) 
TIPHIA PUNCTATA Robertson 
I have examined the type specimen of this species. In my material 
here I have a very large number of males and a smaller, though still 
large, number of, females which I consider belong to the species. There 
are some slight differences between the male examples from the various 
localities but, while I think that there are several species in the lot, I do 
not consider it advisable to attempt to differentiate them with the speci- 
mens I have as criteria. So closely related are the forms that it is not 
impossible that what I regard as probably distinct species are merely 
local variants of one and the same species. For the present, then, I leave
