an acute angle. Palpi black or dusky, the two terminal joints sometimes whitish. 

 Femora black, their extreme tip, the tibiae and tarsi yellow, the terminal joints of the 

 tarsi and claws are more or less distinctly brown or dusky. In some females the 

 yellow portions of the legs and tarsi are almost white. Tegulse yellowish; cenchri 

 whitish. Wings violaceous hyaline, sometimes yellowish or pale brownish. Stigma 

 and veins black. Costa pale. The antennre of the female are simple, quite stout; 

 closely covered with short hairs, those of the two basal joints being somewhat longer 

 and coarser. The lower edge of the third joint is slightly excised, whilst the fourth 

 is slightly stoutish at the apex. On the upper side of the third and fifth there is a 

 quite distinct, short, tootli-like projection. 



Described from 17 males and 20 females. 



Egg. — Length, 0.8 mm. ; color, white. Somewhat flattened, rounded, and stoutest 

 at the anterior end; more pointed at the opposite end. 



Larva. — Length of full-grown larva, 16 mm. ; diameter, 2.4 mm. Color somewhat 

 variable, ranging from a dirty yellowish-green to a glaucous green ; the medio-dorsal 

 line slightly brownish in the paler and slightly darker green in the darker specimens. 

 There may often be noticed a narrow, faintly whitish stigmatal line, and occasionally 

 a rather broad, pale dusky, slightly oblique, subdorsal stripe on pro- and meso-thorax. 

 Head, hairy, greenish-yellow, closely covered with minute, faintly elevated, more or 

 less circular, flat, orange sculpturing, which gives to the head an orange appearance. 

 Clypeus orange, its anterior third greenish, with a small blackish spot at each an- 

 terior angle; eyes black; mandibles black or brown at apex. The whole larva is 

 quite bristly, especially at the sides. Each segment is divided by three transverse 

 rows of transversely elongated, polished warts, each giving rise to a number of 

 rather stiff, pale, glistening hairs, legs pale greenish-yellow; claws brownish at tip. 



Pit^ja.— Color, grayish green ; the thorax and end of body slightly yellowish ; head, 

 whitish-green; ocelli brown; eyes, black. Antennae, wing-sheaths, and legs white 

 with a slight green tinge. 



Cocoon. — Length, 8-9 mm.; color, pale brown. Delicate, semitransparent, spun 

 tightly to the lower surface of the leaves or other obj ects. It is generally surrounded 

 by an irregular, ragged fringe, indicating a tendency to an additional external cocoon. 



THE BANDED EMPHYTUS OR CURLED ROSE WORM. 



(Emphytus cinctiis L.) 



In addition to the common Kose Slug {Monostegia rosce Harris), and 

 the species just described, there is a third saw-fly which breeds on the 

 leaves of the Eose in i^arts of this country. I refer to the imported Eose 

 Saw-fly {Umphytus cinctus L.), which was found by Mr. John G. Jack 

 on the Eose at the Arnold Arboretum and in other botanic gardens in 

 Boston and Cambridge. During the years 1887, 1888, and 1889, this 

 insect was reported as being fully as injurious as the common Eose 

 Slug. (See Garden and Forest, vol. iii, p. 151, March 26, 1890.) Mr. 

 Jack determined this as a European species which he thought to have 

 been recently imported and probably in the stems of rose plants, in 

 which the larva sometimes burrows to undergo its transformations or 

 for winter hibernation, which habit also has led some European obser- 

 vers to consider this insect as a rose stem-borer rather than an external 

 feeder. In the case of this insect again an American species has been 

 chara^ctevized {Emphytus cinctipes l^ort.) which cannot be distinguished, 

 from the description, from the European species and which will un-
