Entom., Sept. 1878, v. 10, p. 176) says this species is doiible-brooiled ia the Southern 

 United States. Packard (Bull. 7, U. S. Eutoni. Coram., 1881, p. 113) figures the larva. 

 Neumoegeu (Papilio, Jan. 1882, v. 2, p. 18) states that this species usually emerges 

 from the pupal state at about 5 p. m. ; Brodie (op. cit., May 1882, v. 2, p. 83), on the 

 contrary, states that the emergence normally takes jjlace about 10 a.m. Riley and 

 others state that the larva has five stages, butWailly (Bull. Soc. Acclim. Fralice, May 

 1882, 8. 3, V. 9, p. 266-267) writes that it has six stages. Brodie (Papilio, Feb. 1882, 

 V. 2, p. 32-33) gives a list of 49 species of plants belonging to 20 genera on which the 

 larva will feed: The genera are Tilia, Acer, Negundo, Primus, Spiraea, Cratcegus, Py- 

 rits, Amelanchier, Ribes, Sambiicus, Ulmus, Qnercus, Fagus, Corylus, Carpinus, Betula, 

 Alnns, Salix, and Populus. From other authors the following genera are compiled : 

 Berberis, Uriodendron, Syringa, Carya, GleditscMa, Bubus, Ceanothus, Ampelopsis, Ceph- 

 alanthus, Fraxinus, Vaccinum, and Bosa. 



Larva. — Body very thick, cylindrical, enlarged at the two last thoracic aud first 

 abdominal segments, the segulents moderately and evenly convex, not angular, 

 sutures distinct. The head is almost wholly retractile within the prothoracic ring, 

 the latter also partially retractile in the succeeding ring. 



Head of moderate size in proportion to the body, rouuded, not so wide as the pro- 

 thoracic segment; green with no markings. It js smaller and less rounded above 

 than in T. polyphemus. Head and body green, the color of the upper side of the 

 plum, birch, or oak leaf. Prothoracic segment with a slight transverse ridge in 

 front, on which are four dorsal small light-blue warts and one larger tubercle on the 

 side, in front of and a little lower than the prothoracic spiracle. On each of the 

 three following segments is a pair of short, club-shaped reddish tubercles with black 

 spines; these are succeeded along the abdomen by two rows of six subdorsal, much 

 slenderer but fully as long, bright yellow tubercles, which have two or three black 

 spines on the end. These two rows are terminated by a single bright yellow tubercle 

 on the last spiracle-bearing segment (eighth abdominal), which is nearly twice as 

 thick as the others. Two lateral widely-separated rows of slender, bright-blue, 

 elongated tubercles, ending in two to four black spinules ; these are slenderer than 

 the dorsal yellow tubercles, and the two rows are far apart, the row of spiracles 

 being between them ; the spiracles are pale glaucous green, surrounded by a very nar- 

 row black rim. On the ninth segment is a transverse row of six pale bright cerulean 

 blue tubercles. Thoracic and abdominal feet a little paler green than the body. 

 Supra-anal plate triangular, large, but obtuse at the end. Length, 70™">; thickness, 

 14""". Providence, October 2. Described from a specimen found feeding on the 

 cherry. 



32. Edema albifrons (Abbot and Smith). 



This eommoa oak caterpillar has been found by Mr. Reed to fre- 

 quently occur on the maple. (Can. Ent., xv, p. 204.) 



33. Forest tent caterpillar. 



CUsiocampa sylvatica Harris. 



A colony of the worms not fully fed were found June 6, collected in 



a mass near the ground on the trunk of the maple at Brunswick, Me. ; 



at this time they were molting for the last time. (See Oak insects, p. 



117.) 



34. Romoptera lunata Drnry. 



Order Lepidoptera ; family NoCTAiDiE. 



In the Canadian Entomologist (xiv, p. 130), Prof. G. H. French de- 

 scribes the seven stages in the life of the caterpillar of this fine large 

 moth, which feeds, he states, on the maple aud willow. The duration
