iered with this beautiful butterfly, one space of about four and a half feet 

 in diameter being entirely hid by a gorgeous coloring of purple, black 

 and white, which shone beautifully in the bright sun. The first stroke of 

 the net disturbed them, but 47 specimens were taken as they hovered 

 about without moving from the spot, and over 100 were taken within a 

 space of 30 feet square. They seemed to be attracted by the brine or 

 water thrown from the pans after freshening bacon and salt pork at the 

 camp fires. Paddling down the creek we passed another congregation 

 of like proportions, but we had a forty-mile canoe voyage to complete by 

 ten o'clock that night in order to catch a steamer at Port Arthur, so they 

 were not disturbed. It is not often an entomologist stumbles upon a sight 

 so beautiful. FRANK S. DAGGETT, Duluth, Minn. 



Perophora mclshcimerii. This elegant case bearing larva was taken 

 at Sugar Grove, O., September 26th, feeding on oak. The single larva 

 examined differs from that described by Harris in the absence of the an- 

 tenna-like appendages at the side of the head; this is also characterized 

 by Packard in "Forest Insects." It is also slenderer than others de' 

 scribed, nor are the "spiracles so situated as to be visible from above,'- 

 except the last pair. The prothoracic segment is not dark like the head, 

 but concolorous with the whole anterior third, i.e., pale brown with diffuse 

 lateral stripes. The case, too, whilst of the same general type as that 

 figured by Harris, is a more finished piece of architecture. One side, the 

 floor, is elliptical and plane; the opposing piece, the roof, is also elliptical, 

 but both longer and wider and cut with the mid-vein in the longer diam- 

 eter, so that when the edges of the two are sewn together it arches up, 

 forming a roof; the mid-vein thus forms the ridge of the roof; this also 

 projects at the ends constituting the verandas over the round openings. 

 The dimensions are: length, 28 mm.; width, 8mm.; height, 6mm.; di- 

 ameter of openings, 4 mm. 



I have not seen the artificer at work. It would certainly be interesting 

 to observe how, with the simple tools at his disposal, so wonderful a house 

 is built. I imagine that the plan of procedure is about as follows: two 

 closely parallel leaves are selected; these are spun together along the 

 elliptical outline of the finished product, the plane one being first strength- 

 ened by a silken lining; then by cutting away the leaves about the outside 

 the case is set free. D. S. K.
