lime, and also various machines used to apply the lime to trees. Discussed 

 by Prof. Riley and others. 



Prof. Riley presented a paper entitled "A New Herbarium Pest," in 

 which he described the transformations and habits of a small Geometrid 

 moth (Carphonera pelearia nov. gen. etsp.) which, during the last two 

 years, has seriously infested and damaged the herbarium specimens in the 

 Botanical Division of the Agricultural Department. These larvae were 

 first noted on plants from the southwest United States, and have confined 

 their work in the main to plants from that section, but are also spreading 

 to eastern plants. A list of the particularly infested plants furnished by 

 Mr. Dewey, of the Botanical Division, was given. A description of the 

 insect, which is a new species and will require a new genus for its recep- 

 tion, was given, and figures of all stages were exhibited. Various means 

 lor the control of this pest were given (see " Insect Life," iv, Nos. 3 and 4). 



Prof. Riley gave some additional notes on Panchlora viridis, in which 

 he referred to the receipt of two additional specimens, one from Gustave 

 Gutenberg, of Pittsburg, and the other from Carl Gissler, of Brooklyn. 

 The first of these, shortly after capture, gave birth to a number of living 

 young and afterwards extruded an imperfect egg-cluster including a num- 

 ber of unhatched eggs; and the other, on dissection, was found to contain 

 a perfect egg-cluster with the young nearly mature and ready to emerge. 

 This egg-cluster, which differs widely from that of the other roaches, was 

 described and a figure of it exhibited. 



Prof. Riley described the modifications of the abdomen in Panchlora 

 which afforded the space necessary for the escape and pre-natal develop- 

 ment of the young within the abdomen. 



The enveloping egg-sac of other roaches was in this species reduced to 

 a scarcely discernible pellicle, which did not cover the eggs entire, but 

 was limited to the inner or concave half of the egg-mass (see "Insect 

 Life," iv, Nos. 3 and 4).
