It may be of interest to note that this package of seed, con- 

 taining thousands of weevils, had a distinctly warm feeling, a 

 fact which has recently been brought to notice in regard to 

 weevil-infested peas and cultivated beans. 



The fourth species of weevil which came out of pods of 

 Cercidium Torreyanum was Bruchus Ulkei, a beetle quite as 

 large as B. amicus and densely covered with a whitish pubes- 

 cence, except the outer half of each wing-cover, which is black. 



extracted from the flowers, and it may be worth noting that 

 the pods sent to Dr. Hagen were represented as being exceed- 

 ingly rich in tannin. 



Species of weevils also infest the seed of Gleditschia, Ro- 

 binia, Cercis, Leucsena and other American leguminous trees ; 

 and the larva of a large Tineid moth has been found to live 

 in pods and seed of Leucaena and Cercidium from Texas.

Dr. H. A. Hagen, of the Museum of Comparative Zoology 

 at Cambridge, Massachusetts, has for many years had several 

 of the foregoing species of beetles and specimens of their 

 work in his biological collection. These were principally col- 

 lected by Dr. G. Engelmann, Dr. E. Palmer and Professor F. W. 

 Putnam in their various collecting and exploring expedi- 

 tions. 



In this biological collection there are pods of Acacia Famesi- 

 ana, which were received from Mexico and found to be much 

 infested by Bruchus protractus, a weevil resembling B. pro- 

 sopis, but rather more slender in shape and darker in color 

 and with heavier markings on the wing-covers. B. amicus 

 also came out of these pods. 



Acacia Farnesiana is now naturalized in nearly all the tropical 

 countries of the globe. It is well known that a perfume is

The Temple Show. 



THE fourth great plant exhibition held in the gardens of the 

 Inner Temple, by the Royal Horticultural Society, on 

 the twenty-eighth and twenty-ninth of May, eclipsed everything 

 of the kind seen here before. There may have been larger 

 exhibitions than this, and it is possible that some departments 

 of horticulture may have been better represented at the 

 famous shows held by this society thirty or more years ago 

 than they were yesterday, but, taken as a whole, the verdict of 

 all qualified judges is, that English horticulture had never 

 before achieved anything like this Temple show. The chief 

 attractions were supposed to be Orchids and Roses, and
