118 TWENTY-SIXTH REPORT ON THE STATE MUSEUM. 



margin by two transversely elongated black spots resting on the 

 black line margining it, and laterally by two geminate similar ones, 

 of which the upper is the larger and the lower embraces the stigma ; 

 behind the lower margin of the stigmatic spot, centrally on the band 

 is a small rounded black tubercle bearing a short hair ; on the poste- 

 rior margin of the band, resting on the bordering black line, are two 

 subdorsal semi-elliptical black spots, forming with the two anterior 

 spots a " trapezoid " ; between these subdorsal spots are two or four 

 black points, of which the two interior sometimes assume the form of 

 a " dove-tail " medial process of the black band ; the orange band 

 extends downward to the black bases of the prolegs, midway between 

 which and the stigmata, on or in range with the third black band, is 

 an elongated hair-bearing black spot, and posteriorly another similar 

 one, lower and running into the black bordering the prolegs. The 

 white band preceding the orange is interrupted or greatly contracted 

 on the medial line by an enlargement of the black band anterior to 

 it, and is marked with a small piliferous black dot in front of the 

 stigma. On the second and third segments the orange band is 

 marked with a row of eight spots, of which the six superior are 

 located in the middle of the band, and the two inferior coalesce with 

 the black band margining it behind. On the eleventh segment the 

 trapezoidal fuscous spots are of a well-defined oval form ; above the 

 stigma is another similar spot. On the twelfth segment the corres- 

 ponding spots are round, and the trapezoid has its broadest side in 

 front. The anal shield bears two spots centrally and five marginal 

 ones, of which the medial one is elongated. On the sides of the 

 larva a yellowish shade rests on the incisures. Yentrally, white and 

 black interrupted bandings are observable on the abdominal segments 

 when extended ; the thoracic region is almost- wholly white ; on seg- 

 ments four and five the orange band is continued beneath, inclosing 

 on the former four and on the latter six rounded black spots. The 

 legs are dull yellow, tipped or edged on the two joints with black, 

 and dotted with black interiorly. The prolegs are dull yellow, with 

 a velvety black base, and with two lateral lines and three black spots 

 (one small) ; the terminal pair have a black line outwardly and a 

 cluster of black spots behind, which, as well as all of the black spots 

 noticed in the above description, are piliferous, having the hair 

 somewhat longer and stouter than in grata. 



Length of the mature larva one inch and one-eighth ; diameter 

 three-sixteenths of an inch.
