different from those of other pulmonate molluscs occurring in the 

 neighbourhood, being spirally ribbed. 



Mr. A. Sidney Olliff exhibited (1) two species of a small fly 

 (Liplosis spp.,), recently bred at the Department of Agriculture by 

 Dr. Cobb and himself from larva? found feeding on rust (Piiccinia) on 

 peaches and sunfloAvers ; (2) a drawing of a larva of one of these flies, 

 illustrating the anatomy of the animal, and exhibiting the embryo and 

 larva of an internal parasite, apparently belonging to the Hymenoptera ; 

 and (3) specimens of a dipteron (Tachina spj, a parasite of the plague 

 locust, Pachytylus australis, Br., which is allied to the recently- 

 discovered Musicera pachytyli, Sk. 



Mr. Maiden exhibited ripe fruits of Monstera deliciosa grown at 

 North Sydney by Mr. J. Malbon Thompson, who believes that this is 

 the first time that these fruits have fully ripened in Sydney. They 

 were fifteen months in ripening after the fruit had set. 



Also, specimens of the " vegetable sponge," Lvffa aegyptiaca, 

 grown by Mr. James Hurst at Summer Hill ; and an abnormal 

 growth of maize cobs, from Batlnu-st. 



Mr. P. N. Trebeck showed some insects collected at^North Sydney. 



Mr. Henry Deane exhibited a fine specimen of Ophideres scdminia, 

 Cr., from Casino, a moth which enlarges, by means of its augerdike 

 proboscis, the holes made by fruit-flies, &c, in the rind of oranges and 

 bananas. 



Mr. Deane also stated that last month, while travelling by night 

 through the Big Scrub in the Richmond River District, his interest 

 was aroused by the remarkable effect produced by luminous insects 

 which abounded by the roadside. Specimens were secured and sent off 

 in the hope that they would arrive in time to be exhibited at last 

 month's meeting, but they came a day too late, and ir> the meanwhile 

 have died. From their general resemblance to the larva? of Ceroplatus 

 mastersi, Sk., which are also phosphorescent, Mr. Fletcher, who had 

 seen the specimens forwarded, was of the opinion that these were very 

 probably also dipterous larva?. 



Mr. David made some remarks on certain luminous organisms 

 which he had observed in old coal mine workings in Illawarra, the 

 identification of which it was hoped would not long be postponed.
