INSECTS INJURING OAK-LEAVES. 187 



Larva. — Its length is If inches. Ground color whitish. Head white, marked with 

 large, round spots, similar to those of Aletia, and numerous minute spots and faintly 

 brown mottlings. Cervical plate white with four small black spots along the anterior 

 margin and two behind them. Median line slightly reddish, bordered by a fine 

 black zigzag line. Abdomen with three pale brown, somewhat interrupted, rather 

 broad dorsal stripes, each of which is also bordered with a very tine black zigzag 

 line. There is also a subdorsal row of narrow, elongated, orange spots, one to each 

 segment. Suprastigmatal band broad and purplish, divided along its whole length 

 by an interrupted white line. Substigmatal baud orange, bordered below by a 

 broader, pale purplish stripe. Venter whitish or yellowish, divided longitudinally 

 by four very narrow black lines. Stigmata black. Thoracic legs white, their claws 

 blackish. (Riley's unpublished notes.) 



Papa. — Body moderately stout, whitish, very pale, spotted distinctly with black: 

 about sixteen black dots on the prothoracic segment. A curved black line on each 

 side of the head. Cremaster flattened, conical, ending in two long, twin, decurved 

 bristles, the outer bri.'»tles either minute or wanting. Length 15'"™. 



Moth. — Male and female. Head and thorax, including the antennae and legs, pale 

 ocherous, extending to the costae of the fore wings, especially the under side. Wings 

 pale whitish, with a slight ocherous tint, with indistinct cinereous speckles, espe- 

 cially marked toward the outer edge ; two parallel lines, the inner a perfectly straight, 

 pale-brown hair-line, situated just before the forking of the median vein, and the 

 outer narrow, cinereous, slightly oblique, but not curved; on the bind wings, which 

 are concolorous with the fore wings, is a single line, very slightly curved in the mid- 

 dle; no discal dot on either wing; outer edge distinctly bent; the tail on the hind 

 wings well developed, but a little less so than in £./a^ifiana, and the wings are broader 

 and shorter, while the anterior pair are not produced so much at the apex. Beneath, 

 the costal edge is ocherous, but the rest of the wing is whitishocherous. The wings 

 are very transparent, so that the lines distinctly appear through. The ocherous head 

 and thorax, including the antennte, in distinction from the pale transparent wings, 

 the pale brown, parallel lines, the inner perfectly straight and the outer one slightly 

 curved, will separate this species from its allies. Expanse of wings, 1.50 inches. 



262. The large scalloped-winged geometer moth. 



Stenotrachelys approximaria Gueuee. 



In the Southern States feeding on the oak a large geometer whose body is ash gray, 

 washed with brown, with a dorsal series of white lozenges, lined with black and trav- 

 ersed in their middle by a twin, interrupted black vascular line. Found in March 

 and April, the moth remaining in the chrysalis. 



This caterpillar, according to Abbot (iu Guenee), lives in Georgia on 

 Smilax rotundifolia and laurifoUa, and, according to Abbot (MS.), on 

 Qiiercus. This species is known to inhabit North Carolina as well as 

 Georgia. In April I found the larvfe on the live oak at Crescent City, 

 Fla., leaving it at the office of the U. S. Entomologist to be reared. The 

 larvae then in confinement entered the ground to pupate, and of two 

 bred moths one emerged November 2 and the other November 11. One 

 proved to be a fine male, the first one I have met with, the female alone 

 having been described in my monograph of this family. It has plumose 

 antennfB and is smaller than the female, but has the same shape of 

 the wings and similar markings. 



Lari'a.— April 22, 1886.— Three larvae of this species were brought to-day by Dr. A. 

 S. Packard, from Florida ; found feeding on above oak. The smallest one of the 

 three is about 1 inch in length, uniformly dark purplish-brown, with the exception
