genus, raised it to Emphor. This bee, it was stated, confines itself 

 alnaost exclusively to Hibiscus, chiefly H. lasipcarpus. The appearance 

 and habits of the bee were described. It was stated that in collecting 

 these bees it is important to catch those flying around the plant without 

 alighting, as these were generally the males^ whilst those visiting the 

 flowers for honey and pollen were the females. On August 5th, when 

 walking along a dam with water on one side, he had noticed a female 

 standing upon the water ; she then flew to a bank, and he observed that 

 she was carrying water to facilitate the excavation of hard ground, into 

 which she was burrowing to build her nest. Sometimes one pellet of 

 earth would be taken out after such an application of water, but at others 

 three or even four. An interesting discussion followed which was parti- 

 cipated in by Messrs. Osborn, Cook, Weed, Fletcher and others. 



Prof. Osborn read the following note " On a Peculiar Form of Coleop- 

 terous larva " : — Eleven years ago, while a student in college, I found a 

 peculiar form of larva boring in the twigs of ash trees, and it was de- 

 scribed at the time in the students' journal at the college (The Aurora, 

 May, 1879, page 5,) under the caption " A Grub With Legs on its Back." 

 The description is as follows : " The specimen was found boring in the 

 pith of a small twig on an ash tree near the road west of the college, ap- 

 parently beginning at or near the tip of the twig and working downward. 

 Numerous twigs were found that had been inhabited in this way, but only 

 one specimen of the borer was found — this about a quarter of an inch 

 long, quite slim, and nearly white. Its great peculiarity consists in the 

 disposition of its locomotive apparatus. The first three segments follow- 

 ing the head are provided with the usual pair of legs, each in the normal 

 position — that is, on the ventral surface. The following six segments are 

 provided each with a pair of pro-legs, similar to those found on many 

 caterpillars, but, strange to say, these are arranged upon the dorsal 

 surface, exactly the opposite of the usual arrangement, while the number 

 six is different from either the caterpillars, where there are four or five, or 

 the saw-fly iarvce, which have eight. The remaining three segments have 

 no propellers whatever. The beauty of this arrangement, for the con- 

 ditions of the borer, can at once be seen, for it has as much foot-hold above 

 as below. Placed upon a flat surface it could make no advancement, but 

 wriggled awkwardly about, evidently seeking its double foot-hold. Placed 

 between two thin plates of glass, it moved rapidly, using all its legs, and
