head, rugose, anterior and posterior margins parallel, anterior margin straight 

 behind head, curving sharply forward behind the eyes; lateral margins explanate, 

 rounded, converging to head, minutely serrulate; posterior margin straight, 

 extremities curving slightly caudad. Mesothorax, slightly wider than prothorax 

 at median dorsal line, thence narrowing to lateral margins, widest at posterior 

 angles, central posterior margin broadly angled, projecting caudad. Melatlwrax 

 slightly narrower than mesothorax and one half as long, constricted in centre, 

 surface smooth. ^Ihdoiiicii, nearly round, dorsum strongly convex, venter slightly 

 convex. Antennae, pubescent; length, 2.4 mm.; 1st segment, .2 mm.; 2nd seg- 

 ment, .86 mm.; 3rd segment, .6 mm.; 4th segment. .6 mm. Legs, strong, tibiae 

 and tarsi slightly hairy, femora with a few sliort liairs. Length of hind tibia, 

 1.0v3 mm. Color, dorsal surface as before, ventral surface of thorax crimson, 

 pleurae dusky, eyes and antennae black. 



Fourth Instar. Shape similar to previous instar; length, 7.5 mm.; greatest 

 width, 4.43 mm. Head, sub-quadrate, flattened, eyes prominent, juga rounded 

 in front, longer than tylus, margins bordered by a small but distinct flange, 

 surface roughened. Prothorax, twice as wide as head, rugose, callosities apparent, 

 anterior and posterior margins. nearly parallel, anterior margin curving sharply 

 forward behind eyes, lateral margins explanate, minutely toothed, posterior 

 margin slightly procurved, posterior angles projecting slightly caudad. Meso- 

 thorax, wider than prothorax and slightly longer at median line, surface rugose, 

 posterior margin angled at centre, lateral lobes short, projecting caudad as far 

 as second abdominal segment. Mclathorax, three-fourths as wide as mesothorax, 

 very short at centre, from thence widening and recurving on each side of median 

 dorsal line. Abdomen, broad, rounded, dorsum convex, venter slightly convex. 

 Antennae, pubescent, distal segment slightly thicker than 3rd; length, 4,2 mm.; 

 1st segment, .43 mm.; 2nd segment, 1.56 mm.; 3rd segment, 1.1 mm.; 4th seg- 

 ment, 1.1 mm. Legs, tibiae and tarsi hairy, femora with a few short hairs; length 

 of hind tibia, 2.3 mm. Color, the same as before, some individuals showing 

 coppery metallic tints on dorsal surface of head and thorax. 



Fifth Instar. Body more ovate, abdomen less tumid, wing pads developed; 

 length, 10 to 12 mm.; width, 7 to 8 mm. Head, as in previous stages but juga 

 relatively longer, lateral margins curved. Prothorax, equal in length to head and 

 twice as wide; anterior margin curved, lateral margins converging anteriorly, 

 explanate and irregularly toothed, posterior margin slightly procurved, lateral 

 posterior angles acute, projecting caudad, surface rugose, callosities larg'e. 

 Mesothorax pne-third longer than prothorax, wing pads extending beyond second 

 al)dominal segment; central portion of posterior margin angled and extending 

 caudad beyond metathorax, surface minutely punctate. Metathorax, very short, 

 narrow, one half as wide as mesothorax, apparent only between the angles 

 formed by the wing pads. Abdomen oval, dorsal and ventral surfaces convex, 

 the larger spots on median dorsal line each with an elliptical rugose callus; inner 

 portion of spots on lateral margins bifurcate. Antennae, pubescent, terminal 

 segment scarcely thicker than the third; length, 5.53 mm.; 1st segment, .5 mm.; 

 2nd segment, 2.i mm.; 3rd segment, 1.43 mm.; 4th segment, 1.3 mm. Legs, 

 strong as in previous instar; hind tibia, 3.4 mm. Color, variable, dorsal surface 

 of head and thorax and spots on abdomen coppery metallic green with golden 

 sheen in some individuals, others with thora.x mottled with red; dorsal surface 

 of abdomen crimson, ventral surface pale red, pleurae dusky, legs and antennae 

 black with metallic green reflections. 



Adult. Uhler's original description (1) is as follows: 



"Podisus crocatus, New sp. — Broad, suboval, more robust than P. cynicus 

 Say., and with blunter and more callous humeral angles. Color dull orange,
