374 PROCEEDINGS OP THE NATIONAL MUSEUM. vol.51. 



hairs on caudal margin the inner pair long, the second pair short, 

 and the third pair long. The 24 other setae are shorter than the 

 long caudal setae; they are situated at equal distances apart on the 

 lateral margins, Vasiform orifice as in the pupa case, but the oper- 

 culum is larger proportionately, and the lateral margins of the orifice 

 are somewhat incurved posteriorly beyond the operculum. Eyes 

 maroon. Abdominal segments distinct. Antennae and legs present. 

 The artist has drawn the vasiform orifice as seen by liim through the 

 transparent body. 



Larva second stage. — Size, 0.45 mm. by 0.32 mm. 



Shape, eUiptical; color, yellow. Two yellow pigment patches in 

 center of abdominal region. Two curved hairs caudad on margin. 

 Vasiform orifice as in the pupa case, but the orifice is situated quite 

 close to the margin. Abdominal segments distinct. Eyes maroon. 

 A marginal fringe of stout, oyhndrical, waxy filaments which are 

 placed quite close together. 



Larva third stage. — Size, 0.7 mm. by 0.5 mm. 



Shape elliptical; margin at thorax angled shghtly outwards. 

 Dorsum almost flat. Color yellow. Two setae caudad, and two 

 setae placed caudolaterally on margm. A marginal fringe of stout, 

 cylindrical wax filaments. Eyes maroon. Abdominal segments dis- 

 tinct. Dorsum granular near margin. Margin broad, faintly de- 

 marcated mesad, and deeply striated radially. There is a distinct 

 yellow band extending from the posterior extremity of the vasiform 

 orifice caudad to margin. There are faint indications of the two 

 radial thoracic bands so conspicuous in the pupa. They end, as also 

 does the band extending caudad to margin, in five separate brown 

 horizontal pores which secrete a small quantity of brown wax. 

 Dorsum covered with a large number of extremely minute circular 

 pores. 



Larva fourth stage. — Size, 1.25 mm. by 1 mm. 



Similar to pupa case except in size; it is also flatter. 



Puparium. — Size, 1.86 mm. by 1.52 mm. 



Shape oval; anteriorly the thoracic margins angled outwards, 

 giving the anterior end a somewhat square appearance. Color bright 

 yellow. Dorsum at first somewhat flat, later turning fairly convex. 

 Three ridges on dorsum, two radiating from thorax to cephalo- 

 thoracic margins, and one from the posterior end of the vasiform 

 orifice caudad to margin. These ridges are dark yellow, blotched 

 with gray. They end marginally in five stout, distinct, brown pores, 

 which produce a small quantity of brown fluffy wax. Margin broad, 

 demarcated mesad by a fairly broad distinct white band, the inner 

 edge of which is dark brown. Margin with strongly marked radial 

 striations, the dorsum also marked around the central area, but the 

 markings are more granular than striated. A small quantity of
