LAKVA OF PSEIDOTIIYATIRA CYMATOPHOROIDE.S (JKOTE. 

 (I'l. XIX, li;.'. ."), ")«, 56.) 



This beaiitil'iil and interesting' larva was detecteJ on tlu' yellow l)ireli at Hruuswick, Me., 

 Anjinst It. It was dark liorn-biown, tlie tail upturned, and the body wiu'u disturlx'd twisted into 

 a partial spiral. The next day it molted. 1 had supposed it might be a Ncttodoutian, but Dr. Dyar 

 on reading my description thinks it is almost surely a Noctuid, and that it has been described by 

 II. Thaxter. The following deserii)tion was made two days after it had molted and before the liody 

 had tilled out, as it tapered sliglitly to tlie end: 



Sta(/e III'. — Length, 8-9 mm. The head is large and broad, somewhat rouiuled, but seen 

 from in front somewhat scjuare, being about as broad as long; it is much wider than the body, the 

 latter not yet being hlled out; it is ])ale, raw sienna brown, with dense reddish brown spots 

 arranged in two broad diffuse median and two broad dill'uso longitudiual bands; it is slightly 

 bilobed and nuich rounded on the vertex, not angular, and with no tubercles. The segments of 

 the body are transversely wrinkled. The body above is of a peculiar dark sea-green hue, and 

 below this runs into a dark umber bi'own. The first thoracic segment has no tubercles or marks, 

 but is dark brown on the sides and on tlie back, with irregular scattered pale spots. On the 

 second thoracic segment is a prominent transverse ridge, with a small tubercle at each end; it is 

 dark on the anterior slojie, but on the summit and on the iiosterior slope whitish ash. This jiale 

 area extends back to the fust abdominal segment, but does not include it, though it passes down 

 to the side of that segment and extends backward, forming a lateral diffuse, rather irregular 

 si)iracular baiul, from which a pair of oblicpie pale stripes extend upward upon the back, not (juite 

 reaching the line nu^dian blackisli line; posteriorly it forms tlu; ])ale edge of the suranal plate. 

 A decided dorsal hump on the eighth abdominal segment, which is dark velvety umber-brown 

 with the hinder edge below whitish. The end of the body is decidedly elevated, and the dark 

 anal legs are as large as the middh; set of abdominal legs, which are tiesli colored. The thoracic 

 legs are dark green, concolorous with the thoracic segment.

Moth, — Head much as in Notodonta; the front shaggy, moderately wide; the hairs abundant; 

 eyes naked. The nuile antenuic broadly pectinated; "female autenua- more shortly and finely 

 bipectinate" (Grote). The palpi much as in Notodonta, being short and broad, the third joint 

 short and conical, but distinct, and reaching slightly beyond the front. The thorax is smooth, 

 not tufted. 



Fore wings not broad, the costa regularly convex ; the apex not produced and rounded as in 

 Notodonta, but uu)derately acute; (mter edge short; inner edge simple, not tufteil. Venation 

 much as in L. haxitrieiis, there being no subcostal cell. Tlie costal region is rather wide; 

 six subcostal branches, the second very short; tlie sixth arises nearer the discal vein than in 

 L. hasitricihs. The arrangement of the discal veins is much as in />. Iiasifricns, their course being 

 nearly straight. Ilind wings somewhat pointed toward the apex. Tlie subcostal does not fork so 

 far out near the outer edgt' of the wing as in Notodouta, while the two discal veins taken together 

 make a regular curved line. 



The abdomen is smooth, not tufted at the end, l)ut conical. Legs moderately stout, pilose; 

 a pair of discal si)urs on the hind tibia- not i>roJecting far beyond tlie hairs. 



Coloration somewhat as in ^Schiziira hptinoiilcs, reminding one at first of that species; fore 

 wings ash-gray, with transverse lines, but the venules only slightly marked with dark spots and 

 streaks. A di.stinct cni'vilinear discal sjjot and Just within it three short parallel distinct brown 

 lines, which are most distinct in the median space. Ilind wings ash-brown. Collar dark.
