Doctor Hopkins spoke of the urgent need of more careful 

 observations on the effect of cUmate upon insects and plants. 

 He had been a close observer of certain insects and their host 

 plants for many years, but he considered this spring (1907) a 

 remarkable one. In the case of the locust borer {Cyllene 

 robinicc Forst.), a certain stage which is ordinarily reached at 

 the time of the opening of the buds was reached at least two 

 weeks before this time, or in other words the insect had reached 

 a later stage than usual before the opening of the buds. 



Professor Quaintance reported that the peach-borer (San- 

 ninoidea exitiosa Say) emerges four to six weeks later in the 

 South and in the North than in the latitude of Washington. 

 The time of emergence in Georgia and Western New York is 

 about the same, although the period of pupation is of about 

 the same duration in all latitudes. 



— Doctor Dyar, under a question of nomenclature, said that 

 of the three species of Tseniorhynchus, one old and two new, 

 Theobald had selected the third as the type because the species 

 titillans of Walker was the species wrongly determined as 

 tccniarhynchus. Dr. Dyar said that here the question of the 

 identification of the species had been raised. The species 

 t<emorhynchus should be considered the type by the rule of 

 tautonomy, but Theobald claimed that it was not the one really 

 before the author and regarded himself at liberty to cite any 

 species he chose. With this Doctor Dyar did not agree, but 

 held that the type must be regarded as tcsniorhynchus Wied., 

 and the genus would thus fall as a synonym of Aedes by Dyar 

 and Knab's classification.
