the base of the fifth abdominal segment, the tips of the tarsi ending about on a com- 
mon level or those of the fore legs a trifle longer. 
Abdominal segments (fig. 11) subdivided into four annuli that bear transverse 
bands of microscopic sete; these bands increase in width from the basal to the apical. 
Spiracles on the pleural region of segments two to seven, lying opposite the third 
annulus and close to the ventral margin of the pleura. No spiracles are discernible 
on the dorsum of the eighth segment. Male cauda (fig. 11) with the ventral lobes 
very blunt, rounded; the dorsal lobes very small, terminating in a sharp spine that 
is directed dorsad and bears a weak seta near its base. Female cauda (fig. 12) with 
the ventral lobes a little longer than the dorsal lobes; the latter at the outer angle of 
the apex with a short stout spine that is directed dorsad as in the male.

The larva is very similar to that of D. winnemana as described above, but is 
slightly smaller. The spiracular disk (fig. 9) has the dark markings much more 
extensive. The mark of the lateral lobes is contiguous with the spiracles and is also 
closely approximated to the large triangular brown mark on the disk. There is a 
large transverse rectangular mark occupying the inner face of the dorsal lobe. The 
marking of the ventral lobe is about as in D. winnemana.
