and all genera of the tribes Artzocerini and Xenorchestini, pos 

 sess jumping power. The smaller species of Cceliodes can also 

 leap very well, and this power is possessed by other Coleopter 

 ous families, including some species of Olibrus, of the family 

 Phalacridse, of which the possession of this power is appar 

 ently not recorded. He said also that with many jumping 

 beetles the hind legs were not thickened. 



Mr. Howard said that the Chalcidids that jump best do not 

 have thickened femora, but possess large apical tibial spines 

 on their middle legs. Prof. Riley referred also to the jump 

 ing power of Psyllidae, which did not depend on incrassated 

 femora. 



Mr. Schwarz further exhibited a specimen of Hymenarcis 

 nervosa with abnormal antennae. The right antenna was nor 

 mal, while the left had but four instead of five joints, the sec 

 ond and third being much thicker and shorter than the corres 

 ponding joints in the right antenna, and the terminal joint 

 being very short and clavate. 



Mr. Schwarz also exhibited a branch of Carpinus ameri- 

 canus, one side of which was healthy and the other dead, and 

 thickly infested with a Curculionid, Acoptus suturalis. It was 

 supposed that the eggs were deposited in living wood by the 

 parent beetle, and that this species is therefore injurious. 



Mr. Schwarz called attention also to a paper by Dr. A. 

 Vceltzkow on the fauna of Vituland (Bast Coast of Africa), 

 published in Das Ausland, 1880, No. 28, pp. 441-445, in which 

 the statement is made that certain small Gryllotalpas captured 

 were always stylopized. Mr. Schwarz said that there was no 

 reason for doubting the correctness of this statement, which 

 added a new order of insects to those (Hymenoptera and 

 Homoptera) known to be infested by Stylopidse. 



Dr. Marx described having recently found a number of 

 specimens of Lathrodectus under a board devouring Carabids, 

 of which fragments garnished the web of the spiders. 



As possibly throwing light on the subject, Prof. Riley men 

 tioned having been greatly surprised this summer at the large 

 number of insects, Xylocopa, Bombus, Lachno sterna, Anthrax 

 and L,epidoptera, particularly Sphingids, that he had found
