occupying from a fourth to a third of the length of the same, and 
also marked with slenderer, and sometimes not so deeply colored 
mediodorsal and lateral longitudinal stripes, which, especially the 
lateral, are apt to expand as they approach the transverse bands ; 
there are signs on some specimens (which may be due to the nature 
of the surface of the stone) of a coarse and sparse punctuation on 
the upper surface. 
Length of wings, 9.5-11 mm.; of legs in a specimen whose 
wing measures 10.5 mm. in length, as follows: femora, 8 mm. ; 
tibiz, 9 mm. ; fore tarsi, 14 mm. ; hind tarsi, 15 mm. 
Florissant, Colorado. Eight specimens, 6 4), 2 9 (the great pro- 
portion of males is exceptional among Tipulinz) ; Nos. 2117 and 
7010, 11668, 11686, 13054 and 13720, 14144, 16402, 16403, 
16405. 
Tipulidea bilineata. 
Pl. 9, fig. 8. 
Wings a little less than four times as long as broad, uncolored 
except for the stigma. Inner marginal cell not regularly fusiform, 
tapering much more rapidly proximally than distally, not more 
than three times as long as broad. Discal cell scarcely smaller 
than the inner marginal cell, also about three times as long as 
broad. Petiole of the second posterior cell fully half as long 
as the discal cell, the second posterior cell itself slightly less than 
half as long as the whole intersected apical area of the wing, which 
is rather longer than the breadth of the wing; fifth posterior cell 
considerably wider at base than just before the margin. ‘The sixth 
longitudinal vein moderately distant from the fifth. Legs very 
slender, the femora increasing slightly in length from the front pair 
backward, the middle pair about half as long again as the wings, 
the tibiz slightly shorter than the femora, excepting in the fore 
legs where the reverse is the case, the tarsi excessively long, nearly 
double the length of the tibia. Abdomen with the hinder edges 
of the segments narrowly edged with fuscous and with distant, sub- 
dorsal, slender, fuscous, longitudinal lines, between which the 
basal segment is wholly fuscous. 
Length of wings, 11-11.5 mm. ; of legs in the larger specimen: 
fore femora, 7.25 mm.; tibiz, 7.6 mm.; mid femora, 7.6 mm. ; 
tibie, 7.25 mm.; tarsi, 14 mm. ; hind femora, 8 mm.; tibiz, 
7.6 mm. 
Florissant, Colorado. Two 9 specimens, Nos. 7998, 11333.
