Side view; b, obliqiieaspect of head; c, thoracic spiracle; d, e, pharyngeal hooks, lateral and dorsal aspect; /, dorsal aspect of caudal segment; ^, anal spiracle, a, Much enlarged; 6-(/, highly magnified. (Original.) Larva cream-white, mm. in length and mm. in diameter. Broadly blunt posteriorly, conically tapering to anterior end. Hook jaws black. At base of second thoracic segment a pair of fan-shaped thoracic spiracles which are pale yellow and ten-lobed. Anal spiracles on rather long papilli- forni tubercles; spiracular orifices of each spiracle three in number and arranged to form a letter T, the stem directed laterad and slightly ventrad. Four small tubercles below the spiracles are ar- ranged in a row across the end of the caudal segment, the outer pair the larger. In front and to the side of this row is a pair of larger tubercles and in front of this pair is a ring of twelve tubercles around the segment; the two dorso-lateral and the two ventro-lateral tubercles large and conspicuous, the others smaller. \'entral swell- ings on segments 3 to 9, inclusive, armed with many small spinous THE PUPARIUM. (Fig. 42.) Puparium ferruginous, dark brown at ends, finely wrinkled. Hook jaws of larva visible. Fig. 4 2. —The legume pod mag- got: Puparium. Much enlarged. ,, ,. , . „ , (Original.)
