Prolegs, dark magenta, with light green claspers. The 11th segment is stouter and higher than all others. Each t}-pical segment bears tw^elve long black setae < six on each side I, arising from raised black tubercles. Head: amber, sparingly clothed with short black hairs. Ocelli and mouth parts black. Plate 42 shows the lar\-a in this instar. in its resting PLATE 42 Larra of Euthisaiiotia brevipennis, first instar, enlarged x approx. 12. Beproduced from painting ty Comm. Charles M. Dammers. In the second instar there is practically no variation from the color and pattern of the first, but in the third instar the Ian, a assumes the mature appearance. Mature lar\ a; length, extended, 29 mm. Cylindrical, shghtly tapering towards the head and thick- ening at the extremity' as far caudaUy as the 11th segment, thence acutely sloping to the suranal plate. Body surface smooth. The ground color is pearl-white. On each rvpical segment there are five transverse black bars. The space between the third and fourth bars is dark orange, except for the 2nd. 3rd and 12th segments where it is pale orange, and the first segment ^vhere the orange is entirely lacking. There is considerable variation in the extent and character of these bands, some examples showing orange spots without black borders, others with the black so largely increased as to leave only a few orange spots. 120.
