142 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



single outer line common to both wings, and a discal dot upon each wing. Wings and 

 body dark yellowish-brown; fore wings with two undulating blackish median bands, 

 the outer the broader and more distinct, both extending across the hind wings; a 

 round black discal dot. Expanse of wings, '4b to aO""™. 



195. Melsheimer's sack-bearer. 

 Perophora mehheimerii Harris. 



This rather singular insect ranges from Massachusetts to Missouri 

 and southward to Georgia, as I possess a colored drawing of it made 

 in that State by the elder Le Conte. I have observed it in Providence 

 early in October. It has been figured in its larval and adult state by 

 Harris, who has given an extended and interesting account of it. The 

 following additional notes are copied from Riley : 



August 28, a larva of this moth was found feeding on oak in Missouri ; others were 

 taken in southern Illinois. The larva is very active and savage when disturbed* 

 turning with great ease in its case and attacking the intruder. Moth from larva 

 received in fall of 1874 issued February 25, 1875, and laid eggs. The eggs are bright 

 yellow, quite large for the insect, and very slightly glued to the sides and cover 

 of the cage in which the moth was confined. At first the eggs are very soft, but 

 in a few days become very tough. They were unfertilized. (Riley's unpublished 

 notes.) 



Larva. — Head with long, slender clavate appendages, bulbous at the end; the 

 head is large, full, rounded, as wide as the prothoracic segment. Body thicker than 

 usual, somewhat sack-like, thickest a little behind the middle, and truncated at 

 the end ; the unusually large supra-anal plate is rounded and convex on the dorsal 

 surface. Spiracles so situated as to be visible from above, large and distinct; five 

 pairs of short, almost rudimentary, abdominal feet; much shorter than in Lacosoma. 

 Head dark brown, as is the prothoracic segment, the two hinder segments paler; a 

 diffuse lateral stripe along the thoracic segments ; rest of the body pale brown. 



Pupa. — Very stout and thick, of the usual shape, but with nocremaster, this being 

 represented by two short, flattened projections; across the abdominal segment a^ 

 double dorsal row of spines. Length, 21™™, 



Moth. — Rather large, in shape and size like the Chinese silk-worm ; male with 

 broadly feathered autennse; reddish-gray, finely sprinkled with black dots ; hinder 

 edge of hind wings and the under side of the fore wings tinged with tawny red. A 

 small black dot near the middle of the fore wings, and both the fore and hind wings 

 crossed by a narrow blackish band, beginning with an augle on the front edge of the 

 former and passing obliquely backward, ending a little beyond the middle of the 

 inner edge of the hind wings. It expands about 2 inches. 



196. The cylindrical baskkt worm. 

 Psyche confederata Grote and Robinson? 



The following notes on this insect have been given us by Professor 

 Riley. We append the original description of the moth. 



A rather curious bag worm, carrying its case almost perpendicular, was found on 

 the oak, June 14. Fastened to cover of breeding-case preparatory to transforming 

 June 24, and emerged as moth July 16. 



The case differs from that of Platoeceticus gloverii Pack, of Florida, in 

 being cylindrical, not oval. (See Glover's figures, in Packard's Guide
