58 INSECUTOR INSCITI^ MENSTRUUS 



The larva has the head broad ; antennae with notch and tuft 

 at the outer third, pale, narrowly blackish at base and on the 

 inner part of the segment beyond the notch. Head-hairs both 

 single, the upper short, the lower long. Air-tube very long and 

 slender, flared a little at the base and expanded at apex, the 

 pecten of long spines reaching nearly one-third the length of 

 the tube. Hair-tufts lost, but six insertions are visible, indi- 

 cating three pairs, all beyond the middle and approximating 

 the ventral line and dislocated, so as to appear as six tufts in 

 profile. Lateral comb of the eighth segment a patch of rather 

 large sharp spines.

Clasp-filament thick, the tip obtuse, scarcely snout-like, more 

 as in Mochlostyrax, the spine appendiculate. Outer division of 

 the lobe of the side-piece slender, columnar, a long filament 

 arising about the middle on the inner side ; a large expanded 

 leaf on the tip on the inner side, close to three blade-shaped 

 filaments, which arise a little on the outer aspect of the lobe. 

 Inner division of lobe of side-piece rather long, one filament 

 arising at apex and the inner one close to base without separate 

 pedicel. Second plate of unci furcate, deeply emarginate, one 

 limb horn-like, the other with traces of denticulations ; a 

 rounded lappet at the base of the fork, but no third spine.
