allies to the gardener and fruit-grower from their aphidephagous propensities. 

 The northern lady-bird was known to Fitch, Walsh and other of our older ento- 

 mologists as being in its larval stages at least an enemy to plants of the cucurbita- 

 ceous family, feeding upon squashes and allied plants, often causing considerable 

 loss in the product. 



The species concerning which he now spoke is quite evidently an Epilachna. 

 Its leaf- eating habits and its appearance point unmistakably to its close relation- 

 ship to our northern lady-bird. From this it differs, however, in being more 

 woolly, darker bronzed yellow and in having smaller black spots. Less obvious 

 differences exist, but these will not here be particularized. 



He gathered from the descriptions of the northern lady-bird, current in ento- 

 mological literature, that our species resembles this also closely in its larval and 

 pupal forms, it being a prickly, yellowish, humpbacked larva, rather sluggish in 

 movements, like other lady-bird larvae, and unlike most of them, living upon the 

 tender parenchymatous portion of the leaves of plants. Our Colorado larva 

 feeds upon the bush bean. The specimens were gathered in a garden where 

 they were feeding on beans in great numbers. The larvae w.ere found principally 

 on the under side of the leaves, and devouring the green portions, they left the 

 woody net-work nearly clean. The pupa is attached to the leaf by the caudal 

 portion with the larval skin in a roll about the tip of the abdomen. The perfect 

 insects were gathered from the leaves where the larvae were found feeding, and 

 the only stage in which the beetle was found abundantly was the egg stage. 



"Ancient Stone Remains on Summit of Rocky Mountains," a paper by J. 

 R. Mead, of Wichita, was read next. It was as follows: 



During the past summer I had occasion to travel over and along the conti- 

 nental divide, which separates the waters of the two oceans, as well as the coun- 

 ties of Gunnison and Chaffee, Colorado, and at a point about four miles west 

 from the town of Monarch, near the head of the South Arkansas, I noticed the de- 

 bris of very ancient works of stone which, considering their location, were very 

 curious and interesting. They comprised a series of low stone walls, and ex- 

 tending along the smooth summit or backbone of the mountain and connecting 

 two elevated rocky points, about a quarter of a mile apart. On the top of these 

 points were circular enclosures of stone, ten or fifteen feet in diameter, and two 

 feet in height ; the walls were made by placing upon edge and leaning together 

 slabs of granite rock, and were originally about two feet or more high and are so 

 ancient that in many places the granite rock of which they were composed had 

 disintegrated, and crumbled into sand. The course of these walls was generally 

 north and south with frequent dips, spurs and angles, side walls and pens, form- 

 ing an intricate system. The design of it was difficult to comprehend. These 

 marks extended across a convenient top in the mountains, at an altitude of about 

 ii,ooo feet, and above timber line. They could hardly have been intended for 

 defence, as the mountain range could be crossed as easily for several miles south 

 as at this point, and I could not see that they would be of advantage in the cap- 

 ture of game. I have heard of such walls on the summit of the mountains further
