brown. Immediately below the spiracles is a row of blue dots, margined with 

 black, one on each segment from sixth to twelfth inclusive. 



Under surface dull pale greenish or yellowish white, having a decided red- 

 dish tinge as it approaches towards the yellow stripe on sides. Feet and 

 prolegs partake of the general color. 



Papilio Turnus — Larvas found feeding on cherry, July 14th. Length 1| 

 inches. 



Head rather large, slightly bilobed, reddish brown sprinkled with very 

 short white hairs. 



Body above green, of a slightly darker shade on anterior segments, paler 

 on sides of body, on which there is a whitish bloom produced by minute 

 white dots with small short hairs of the same color issuing from them. An- 

 terior segments of body wrinkled. On the anterior edge of second segment 

 is a raised yellow fold, slightly overhanging the head, and on each side of 

 fourth segment is an eyelike spot nearly oval in shape, yellow enclosed by a 

 ring of black, centered with a small elongated blue dot, which is also set in 

 blaek and has above it on each side a black line, nearly crossing the yellow 

 spot. On posterior portion of fifth segment is a raised yellow fold, bordered 

 behind with rich velvety black, the latter visible only when the larva is in 

 motion ; on the terminal segment is a similar fold, flattened above, with a 

 slight protuberance on each side. On fifth segment in front of the yellow 

 fold, are two blue dots, one on each side the dorsal line ; there are also faint 

 traces on hinder segments of a continuation of these dots in longitudinal 

 rows. 



Under surface of a paler green than upper, with a whitish bloom, prolegs 

 of the same color, feet tipped with brown. 



As the larva approaches maturity and is about to change, the color of body 

 grows much darker, becoming dark reddish brown, the sides nearly black. 

 The minute whitish granulations and the blue dots become more distinctly 

 visible, giving the larva a very different appearance. 



Both Troilus and turnus winter in the chrysalis state. The first specimens 

 of Troilus appear with us about the middle of June, becoming more abundant 

 early in July. I think there is only one brood, but in this may be mistaken. 

 Turnus I have taken on the wing from the middle to the latter end of May, 

 but it becomes much more plentiful during July, and I incline to the opinion 

 that there are two broods during the season. 



Danais ArcJiippus. — Larva taken full grown, July 18th, feeding on differ- 

 ent species of Asclepias. 

 ' Length one inch and three quarters. 



Head yellow with a triangular black stripe in front and another of a 

 ■ similar shape above.
