brancli, by the aid of a thread of silk, when inclined to wander. I have one 

 in a vial of sjjirit that was feeding, the only one I could procure, and four 

 others that had closed their sacks for the season," etc. " The drop-worm 

 pod, which I enclose, is empty. It is ofi' a maple, and larger than the one 

 last sent. My brother promises a box full from Maryland, where he resides. 

 He says they have been on his cedar trees in profusion this summer." 



Larva (in spirit), taken Sept. 20?, fusiform, broadest across the fifth ring, 

 as seen on the back, but seen laterally the third and fourth rings arc the 

 thickest. Length fifteen sixteenths of an inch. Body, except the head 

 and first thi-ee rings, livid, smooth, without hairs. Head moderate, hemi-

 ^» ' " * ^ form of an angle in front, and behind them on each side three 

 lineal' spots, Avitli others of an irregular shape near them. Five 

 eyelets in a circle, immediately behind each of the palpi. First 

 seo-mont corneous above, white, regularly ornamented with black spots, 

 second and third segments shorter and much wider. The second with a 

 transverse, corneous, white plate above, marked Avith four large, longitu- 

 dinal, black spots, and two black dots; third segment with transverse, oval, 

 corneous plates, particolored black and white. Legs very large, all directed 

 forwards and claw'-like, having the coxas of each pair very large, lamellate, 

 and coalescing by a suture. The third pair of legs the largest, the others 

 progressively smaller, all ending with a single stout claw. Coxa; parti-

 clappet perpendicular. The larvte are found in their cases with the head 

 towai'ds the top, the case having a cylindrical hole above as well as below, 

 but the upper one closes naturally by the weight of the case when hanging. 

 All the dead larvte were found head uppermost, and never towards the 

 lower orifice. 



Pupa of the male head downwards, and half exserted' when the insect is 

 ready to disclose the moth. 



Put a quantity of the pods on tjie arbor vita; in May. Found the larvas 

 and their pods, the latter three eighths of an inch long, on the arbor vita3 

 and adjacent apple trees, July 20, 1850. 



Limacodes seapha Ilarr. [PI. m, fig. 8.] 



In Sept. and Oct. 1827, I found on the apple tree some small larva;, sim- 

 ilar in form and color to the one figured, which came from the black walnut 

 tree. They were deep green above, the lateral angles and margins reddish; 

 pale green beneath; feet (if any) retractile. Cocoon dense, almost parch- 

 ment-like.
