of each of the abdominal segments. The hair tufts are about as 

 long a.s a single body segment, excepting on segments one and 

 two, where they are shorter or entirely wanting. The head is 

 brown, about 1.5 times as long as wide; antennae, labrum, and 

 epipharynx resembling those shown on pl.25, fig.3; the setae at 

 the apex of the labrum longer than shown here. Mandibles 

 (pl.24, fig.6) with a branched basal and two simple dorsal setae; 

 convex side wrinkled. Maxillae (fig.5) with short palpus, a few 

 papillae and a tuft of mesad projecting setae. The labiuui (fig.5) 

 somewhat triangular, having a toothed outline as shown in the 

 figure. Prothoracic feet with numerous curved yellowish brown 

 setae. Abdominal setae as described above. The anal prolegs 

 and appendages were destroyed in the few specimens which I 

 have. 



Pupa. Length 8 to 4 mm. with black and yellow markings of 

 the adult showing through the integument. Each prothoracic 

 respiratory organ is slender, nearly cylindrical, with smooth sur- 

 face and rounded ends, its length about 0.25 inni. (fig.8.). The 

 markings of the second, third and fourth abdominal segments as 

 shown in fig.7. The fifth, sixth and seventh are similarly though 

 much less plainly marked. The markings on each segment con- 

 sist of a large area of very minute caudad projecting setae with 

 a few scattered bare patches, a transverse band of stouter caudad 

 projecting setae near the posterior margin and a band of cephalad 

 projecting setae upon the margin. The latter band is particu- 

 larly conspicuous on the second segment. The caudal appendage 

 is quite small, and is provided with three pale setae on each 

 posterior angle (fig.10, which also shows the male genitalia of 

 the enclosed imago). 



Imago, male. Dorsum of the thorax yellow, with three wide 

 nearly confluent shining black stripes; a spot on each pleuron, 

 the scutellum, sternum and the metathorax also black. The 

 abdomen dull black, the first, fourth and seventh segment with 

 pale yellow cross bands ; besides this the posterior margins of the 

 other segments narrowly white; anal segment thicker than the 

 others ; forceps white. Head yellow ; the palpi black ; the antennae 

 brown, its hairs white at the tip. Legs black, the fore coxae, the 

 bases of all the femora, a broad band on each tibia whitish; the 

 fore tarsi black or brown, each middle tarsus with its two basal 

 joints, and each hind tarsus with three basal joints white. Meta- 

 tarsi of the fore legs of the male only one half as long as the 

 tibiae. Wings whitish. 



Female. Abdomen more yellowish ; one may say, abdomen yel- 

 low with three black fasciae, the two anterior ones each divided 

 by the light colored incisures; the legs also with more yellow.
