1918] Leaf Eating Crane- Fly 85 



Pupa (Fig. 14). — Length from head to tip of abdomen, d^, 11.7 mm.; 

 9 , 13.3 mm. Length from head to tip of tarsi, cf , 5.9 mm. ; 9,6 mm. 

 Dextro-sinistral width at the wing-pad, (f, 2.2 mm.; 9, 2.8 mm. 

 Dorso-ventral depth at the wing-pad, d^ , 1.4-1.6 mm.; 9, 2 mm. 

 Color leaf -green, thoracic spiracles grayish- white, margins of abdominal 

 segments sub-translucent, eyes black in mature individuals. 



Bases of antennae arising between the cephalad half of the com- 

 pound eyes, slightly divergent on either side of the mid- ventral line, 

 more so in the male than in the female. In the male, the antenna rather 

 enlarged, bending round and closely appHed to the anterior margin of 

 the compound eye as far as the point where the palpi, reflexed antero- 

 laterally, terminate; then directed postero-medially in the line between 

 the fore femora and tibiae, the extremity about on a level with the lobes 

 of the labium. In the female, the antennal sheaths less stout, continuing 

 around the anterior margin of the eye latero-posteriorly, abruptly bend- 

 ing posteriorly a short distance from their tips to terminate above and 

 just beyond the proximal extremity of the second tibias; in mature 

 specimens, the irregular, nodose segments of the adult antenna apparent 

 through the transparent sheath. Eyes large. Labium elongate, tri- 

 angular. Head flat and broad dorsally, sloping back to the thorax, 

 devoid of tubercles. 



Pronotal breathing horns prominent, somewhat enlarged distally, 

 directed antero-laterally with a distinct, ventral inclination. Meso- 

 notumfaintly wrinkled, pronouncedly arched, with two tubercles one on 

 each side of the dorso-median line at the apex of the arch, directed 

 cephalad and laterally; slightly anterior and external to these, a smaller 

 tubercle at the base of wing-sheath. Metanotum devoid of tubercles, 

 slightly wrinl<:led. The fore femur long, terminating on a level with the 

 middle region of the eye, fore tarsi longest, hind tarsi shortest with a 

 corresponding relationship in the comparative length of the seginents of 

 each tarsus. In the female, the tip of the hind legs just anterior to the 

 caudal margin of the third abdominal segment, extending slightly beyond 

 those of the first and second pair which are on a level; in the male, the 

 tips of all three pairs of legs in alignment just anterior to the caudal 

 margin of the second abdominal segment, the wing-cases completely 

 overlapping the tibia and first tarsal segment of the hind legs. 



Abdomen of eight segments, dorsally with the first segment half as 

 long as the second; segments II-VII subequal in length, devoid of 

 tubercles except in so far as small indistinct lateral protrusions may be 

 so considered; segments with transverse wrinkles subparallel or curved, 

 isolated or converging and confluent; lateral margins somewhat 

 appressed. In the male, the eighth or terminal segment contains the 

 genitalia of the adult; the ninth tergite a small, well-defined plate with 

 posterior margin slightly concave, lying superior to but only partially 

 covering the valve of the ninth pleurite with its recurved appendages 

 which extend beyond, both laterally and posteriorly; the pleural 

 appendages distinctly evident, recurving dorsally on each side of 

 median line of the valve and terminating at the ninth tergite. From 

 beneath, valve of hypopygium divided by a small, median notch into
