The finding in the spring of 191 5 of a male P. vernata in cop. 

 with a female A. pometaria proved puzzling at the time, sug- 

 gesting the possibility of a third species. Eggs deposited about a 

 week later were of the flower-pot shape typical of A. pometaria 

 and experiments were not carried further. 



While the paucity of the males of A. pometaria remains to be 

 accounted for, the apparent scarcity of females of P. vernata 

 can be explained by their habit of remaining at the base of trees, 

 concealed by grass or fallen leaves until heavy rains or (as 

 happened April 9, 1916) a heavy snowfall forces them to climb to 

 greater heights. On that day 2 female vernata and 3 pometaria 

 were collected in a short time. 



That the Fall canker worm still appears in destructive numbers 

 on Long Island, though at a considerable distance from the city, 

 has been reported, especially as defoliating deciduous trees at 

 Wading River. (Cf. Bulletin papers by W. T. Davis, Vol. IX, 

 p. 23, and Vol. X, p. 82.) Evidently our native insectivorous 

 birds cannot be relied upon to check the insect pest. Therefore, 

 let us give the devil (English sparrow) his due. 



A NEW GENUS AND SPECIES OF NORTH AMERICAN 

 CHLOROPID^ (DIPTERA). 



By J. R. Malloch, Urbana, 111. 



I obtained the species described herewith while collecting ma- 

 terial for a paper on the immature stages of Diptera, now nearly 

 ready for the press, and because it has no direct bearing upon 

 that study, and in order to keep my other paper within reasonable 

 compass, I have decided to publish the present description. While 

 the manuscript containing this description was still awaiting dis- 

 posal, Professor J. M. Aldrich brought to me for examination an 

 example of the species, which has been recorded by me as a para- 

 type in this paper. The type specimen is in the collection of the 

 Illinois State Laboratory of Natural History.
