Exhibitions, §-c. 



Mr. W. W. Saunders exhibited two larvae of Cicada? fiorn Mexico, each of which 

 had a Clavaria growing from between the eyes; the fungi were probably of the same 

 species, though dissimilar in their development. He remarked that these fungoid 

 excrescences were most frequently found on Lepidopterous larvae, and usually arose 

 from the joint immediately behind the head; in the present case, however, the 

 Clavaria? sprang from the front, giving to each larva the appearance of the conven- 

 tional unicorn. It was a question whether the growth of the fungus commenced 

 during the life of the insect; he was not aware of any observation which supported 

 that notion, and thought that the growth did not begin till after death. Acting upon 

 the suggestion of the President, Mr. Saunders promised to bring forward for dis- 

 cussion the subject of "Fungoid growths on Insects" at a future Meeting, of which 

 due notice should be given. 



Mr. Bates mentioned that some capital articles on insect-fungi by Mr. Cooke had 

 recently appeared in Hardwicke's ' Science Gossip.' 



Mr. W. W. Saunders exhibited two larva-cases sent from Brazil by Mr. Eeed, one 

 of which was zoned or ribbed in different directions so as to form quite a regular 

 sculpture on the outside; the two were somewhat similar, and probably belonged to two 

 species of the same group of Coleoptera. 



Mr. Janson exhibited various new or rare Coleoptera recently received by Mr. 

 Bakewell, from Dr. G. Hovvitt, of Melbourne, viz., Hemiphasis Bakewellii, White, 

 from Melbourne; Passalus teres, Perch., New South Wales; Lissotes obliterate, 

 Westw., Hobarton ; Lissotes cancroides, Fabr., Hobarton ; Lissotes subtuberculatus, 

 Weslw., Hobarton ; an apparently nondescript species of Lissotes from Victoria, to 

 which Dr. Howitt applied the trivial name " furcicornis"; anew species of Cera- 

 tognathus, from Hobarton, for which Dr. Howitt proposed the specific title 

 "setiger"; and Dorcadida bilocularis, While, from Hobarton. 



Mr. Staiuton exhibited the specimen of Stathmopoda ? Guerinii, which he had 

 received from M. Gueiin-Meneville in 1857, with the intimation that it was " eclose 

 d'une grande galle sur le pistacier," and which till last month had remained unique. 

 Towards the end of September Dr. Staudinger, who had gone on a collecting expedi- 

 tion to Celles-les-Bains (Department of Ardeche) sent over some Nepticulized leaves of 

 Pistacia terebinthus, and on the 28th of September Mr. Stainton wrote suggesting a 

 search for the gall-feeding Stathmopoda. On the 2nd October Dr. Staudinger wrote 

 in reply -. — " Many thanks for the notice respecting Stathmopoda ? Guerinii, of which 

 I herewith send you five larva?. I had long noticed the galls on the Pistacia (often 

 very large), and had opened some, but there were thousands of Aphides within and a 

 quantity of white dust, so that it seemed an unprofitable occupation. To-day, 

 however, I have renewed my search with fresh energy, though it is very dirty work, as 

 there is besides a resinous secretion. I found, however, two sorts of larva? in them, 

 generally living amongst hundreds of Aphides, on which they probably feed, since I 

 did not find the inner parts of the galls eaten ; the larger larva belongs to the 

 Phycidea?, and the smaller white larva is that of Stathmopoda? Guerinii; of this 

 latter I also found pupa?, and in one firmly closed gall a fresh specimen of the perfect 

 insect. There are three kinds of galls on the Pistacia ; the largest is at the ends of the
