illustrating- extremes in coloration. Mr. Grossbeck showed a 

 box of Geometrids and spoke of the great amount of varia- 

 tion many of the species displayed. Especially interesting 

 was a specimen of Thcrina fisccllaria, in which the two nor- 

 mally widely separated cross-lines anastomosed and parted at 

 the point of juncture, thus forming a quadrangle with the costa 

 and a triangle with the inner margin. A similar case was 

 that of Mcsolcnca gratnlata, where the basal and outer fields 

 joined centrally, having a small white costal and inner mar- 

 ginal spot to represent the usual broad median area. Mr. 

 Broadwell had a fine series of Tclca polyphcmus, showing the 

 gradual variation from pale yellow to dark reddish individ-

A meeting of the Newark Entomological Society was held 

 February 9, 1908, with eighteen members present and Mr. 

 Henry Dietz, of New York, a visitor. 



Mr. Brchme read a paper entitled "Notes on Some Saturn- 

 iid^e" in which he spoke of the large percentage of dead cat- 

 erpillars in the cocoons he had collected last fall. Sainia cc- 

 cropia fared worse than all other species in this respect, scarcely 

 A^/2 per cent, containing live pupre, and, of the dead ones only 

 i per cent, of those examined were infested with parasites. 

 Tclca pol\phcmus unlike 5\ cccropla died mostly in the larval 

 stage, and just before the season of pupation hundreds of lar- 

 vae could be seen hanging limp from the branches of their 

 food-plants. Of those that succeeded in forming cocoons 60 

 per cent, were invalid, and, as in the case of cccropla, died be- 

 fore pupating, though the inner as well as outer wall of the 

 cocoon was fully formed. Protnctlica, on the other hand, 

 seemed not to be affected by disease at all and even escaped 

 to a remarkable degree the usual infestation of parasites. 

 Cviifliia was not inclined more in one direction than in another 

 and the percentage of good cocoons remained at a par with 

 former years.
