witli the inner margin. The second or transverse posterior line is more 

 oblique, bending outward near the costa and with a more pronounced 

 sweep than the following. The third or subterminal is margined inward- 

 ly with a faintly darker shade of the ground-colour. The extreme outer 

 margin and fringes show a golden lustre. The reniform is indicated by 

 a straight mark of the same pale shade as the lines, and is at right angles 

 with, though not touching, the costa. At the outer margin, near, but not 

 on, veins three and four are two minute black dots. In a description of 

 this insect in Trans. Am. Ent. Soc, X., 247, no mention is made of these 

 dots and they may be perhaps a sexual characteristic. 



The secondaries are lighter, discoloured white, of the same lustrous 

 sheen, shading darker at the outer margin, but with fringes less golden 

 than primaries. Expanse, twenty-four millimeters. 



Other captures, referable generally to a more southern fauna, are 

 Polygrammate hebraicuiii, Hbn.; Laphygma frugiperda, S. & A.; Pro- 

 denia eudiopta, Gn.; Plusia basigera, Walk.; Schinia lynx, Gn.; S. 

 Thoreatii, G. & R. 



WINTER BREEDING OF DIABROTICA VITTATA IN 



FORCING HOUSES. 



In the "Journal of the New York Entomological Society" for June, 

 1896 (Vol. IV., No. 2, p. 68), the present writer recorded the occurrence, 

 on December 28, 1895, of adults, and larvae from one-half to two-thirds 

 grown, oi Diabj'otica vittata, in a greenhouse near Cincinnati, Ohio, that 

 was being used for growing cucumbers for winter market. The injuries 

 inflicted upon the young cucumber plants were very serious, and resulted 

 in a nearly total destruction of the plants. On March 25, 1899, serious 

 injuries were again reported by the proprietors of these same green- 

 houses, and the complaint was accompanied by specimens of what, to 

 all appearances, were the larvse of this same species. These larvae were 

 placed on the roots of a squash plant growing in the insectary, and 

 on the morning of April 24th the adults made their appearance, thus 

 showing that, under proper conditions, the species will continue to 

 reproduce the year round, whereas out of doors, and under normal con- 

 ditions, the insect hibernates in the adult stage. F. M. Webster.
