the usual pair of bristles just behind them, while the two large, 

 pointed respiratory tubes protrude through the cocoon, as 

 though utilized by the pupa in making its way forth. Pupal 

 period, six days. 



On making its way from the cocoon to the surface of the 

 ground, the pupa travels by the aid of the spinulose ridges on 

 the back. One under observation, which had pupated in water 

 in a watch-glass, crawled to the rim and traveled three times 

 around the edge entirely on its back ; and another, which 

 emerged under a bell-glass, traveled for a distance of six inches, 

 also on its back, over the moistened inner surface of the glass. 



Rdult (PL III., g, h). — " Antennae in both sexes slightly 

 shorter than the head and thorax taken together, nine-jointed; 

 joint 1 obconical, 2 globular, wider than any of the others; 

 joints 3 to 8 only slightly longer than wide, subsessile, the 

 hairs very sparse, not arranged in whorls; joint 9 almost twice 

 as long as 8, slightly constricted near the middle. Wings hya- 

 line, bare except along the hind margin near the base and on 

 the veins, which are sparsely bristly, rather densely bristly 

 aloug the first half of the costa, interspersed with flattened 

 bristles; the first vein lies very close to the costa, which it joins 

 slightly before the middle of the wing; third vein evenly ar- 

 cuate, joining the costa far before the extreme apex of the 

 wing, this distance almost equaling one-half of the greatest 

 width of the wing, the extreme base of this vein, where it 

 joins the first vein, very indistinct; fifth vein indistinct toward 

 its apex, forked at its last fourth, the anterior fork reaching 

 the hind margin a short distance basally of the tip of the 

 third vein. First tarsal joint less than one-half as long as 

 the second, claws of tarsi simple. Color of alcoholic speci- 

 mens yellow, the head and thorax tinged with brown. Length, 

 1 to 1.25 mm." (Coquillett.*) 



NATIVITY OF THE INSECT. 



In the light of the foregoing it will be seen that our rose- 

 attacking insect is not a native species, else it would certainly
