40h: 
Outline of female of Colemania sphenarioides, Bol. dissected to show the various external features. 
The elytron or wing- 
cover is removed and only the base of the hind leg is shown. 
as varying from seventeen 
to nineteen. 
The antenne are thick- 
est at about the third seg- 
ment and taper from here 
eradually to the end. In 
the female, segments 3-8 
have in section a triangular 
form which is particularly 
marked in segments 3-5. 
The more distal segments 
cradually change to a cy- 
lindrical shape. In the 
males, this triangular shape 
of the segments is usually 
not nearly so distinct, be- 
ing marked usually only on 
seements 3 and 4. Plate 
X, Figs. 1 and 2 show these 
differences in structure. 
The antenne of the female 
is marked on the lower 
angle with a narrow yellow 
band extending to the 8th 
segment. In the male this 
band is, at least usually, 
absent. Another feature 
which commonly varies 
shehtly from the descrip- 
tion given by Bolivar is the 
colour of the hind tibie. 
While some — specimens 
have the hind tibiz reddish 
throughout, in the majority 
of cases the basal half of 
the tibia is flavescent, only 
the apical half being red- 
dish.’ 
Bolivar’ places this form in his section Orthacres,
