[sic] data from month to month and year to year with relation to the 

 several' factors that influence insect abundance. The results to be 

 obtained from this undertaking over a series of years are manifold; we 

 should be able to throw light on the reasons for the cyclic appearance of 

 certain insect pests, the gradual shift of regions of destructive abund- 

 ance, the limiting barriers to normal dispersal, the directive influences 

 that determine the paths of insect diffusion, and the relation of climatol- 

 ogy, geography, topography and geology, as well as biological complexes, 

 to insect distribution and abundance. This is the necessary foundation 

 for the next advance step in economic entomology, entomological fore- 

 casting. 



The degree to which this Bulletin realizes these high hopes 

 must be decided by those who read it. The object is one well 

 worthy of the support of both pure and applied entomologists, 

 since it lies within the fields of both classes of students. It 

 appeals to those without as well as within the Bureau as, for 

 example, to Mr. John J. Davis, who has argued for An Indiana 

 Insect Survc\ in the Proceedings of the Indiana Academy of 

 Science. Mr. Davis would 



explore, exploit, record, map, collect and study the insect fauna of 

 Indiana, determine the occurrence and range of all insects of the state 

 and study their relation to plants, animals, human welfare, etc. Such 

 a survey would include a study of the relations of insects to changing 

 conditions, that is, swamp areas being reclaimed by drainage, peat bogs, 

 sand areas and the like, being put under cultivation for the first time, 

 etc. It would also include studies of the small lake areas, caves and 

 similar places. 



May all these surveys be carried out in detail !

ENTOMOLOGICAL GLEANINGS FROM ALL QUARTERS OF 



THE GLOBE 



Protoparce rustica in Florida (Lep.: Sphingidae) and Mr. T. L. Mead 



Mr. Theodore L. Mead has sent us a moth, Protoparce rustica. He 

 says the caterpillar feeds on Callicarpa amcricana, down at his home, 

 Oviedo, Florida. The larva of this species appears to have a variety of 

 food plants. The life history is well illustrated in ENTOMOLOGICAL NEWS, 

 1900, xi, 485. Mr. Mead has not been collecting insects for forty years 

 but still takes an interest in them and gets specimens for friends in this 

 country and Europe. He was a famous collector and writer in the past 

 and his work is known to most Lepidopterists. H. SKINNER.
