Prof. Riley mentioned other examples of very minute insects 

 possessing a very pungent odor, instancing Corimel&na and 

 Anthocoris on raspberries and blackberries, the odor of which 

 may be detected long before the insect is seen, and this is 

 frequently from very young and consequently very minute 

 specimens. 



Mr. Ashmead remarked that the odor on raspberries was also 

 frequently caused by Triphleps insidiosus as well as by Corime- 

 l&na. The young of the former insect is much smaller than 

 even Corimelcena and is not much more than half the size of 

 the insect exhibited by Mr. Howard. 



Mr. Howard said that Mr. Smith was a very careful observer, 

 and that his statement as to the peculiarity could be implicitly 

 relied upon. 



Dr. Fox showed a specimen of an undescribed species of 

 Phrurolithus, in which the palpi were intermediate between the 

 normal male and female, the tarsal joint being without pro 

 cesses, as in the female, while the tibial process was distinctly 

 present, but much smaller than in the male. He considered 

 the malformation to be due to a lack of development. 



Dr. Marx observed that this monstrosity resulted from an 

 injury to the specimen, which had caused a retardation of the 

 development of the palpi. 



Prof. Riley asked whether such an injury would result in a 

 change of the sexual characters, to which Dr. Marx replied 

 that the palpi, which in the young are very simple and alike 

 in both sexes, take on the characteristic enlargements and mod 

 ifications peculiar to the male sex on the maturing of the insect. 



Mr. Fernow made some additions to his previous communi 

 cation on Psilura monacha. He stated that the government of 

 Germany has recently appropriated $350,000 to fight this moth, 

 most of which will be spent on the lime treatment. He also 

 called attention to a monograph on the May beetles of Europe 

 (Melolontha spp.), which he said contained a great many facts on 

 the habits and means of treatment of these pests. He mentioned 

 a fact given in this publication, viz., the migration of the 

 larvae, which he believed to be a new observation. The only 

 method of treating these insects of any value is the collection 

 of the full-grown larvae, pupae and adults. He also mentioned
