In the latest United States Dept. of Agriculture Bulletin on the 

 Periodical Cicada, Mr. Marlatt says that " an instance of a few weeks 

 acceleration under out door conditions is given by Mr. Schwarz. 

 Commenting on the slightly early emergence of individuals of Brood 

 XIV near Harper's Ferry, W. Va., in 1889, in a small clearing sur- 

 rounded by woods, Mr. Schwartz urges that a clearing made in the 

 midst of a dense forest forms a natural hot house, the soil securing 

 in such places much more warmth than in the shady woods. That the 

 cicadas should appear a little earlier in such situations is not remark- 

 able, and he suggests also that under favorable circumstances the 

 cicadas might develop on such cleared places one or more years in 

 advance of the normal time, and that these precursors, if numerous- 

 enough, would be able to form a new brood." 



In the Long Island locality they were certainly numerous enough 

 to lay a great many eggs, and may possibly establish a new brood. 

 Brood No. i (1910) is not recorded from the states of New Jersey 

 or New York, but occurs more to the south and southwest, whereas 

 Brood No. 2 (1911) is well known in New Jersey, Staten Island and 

 part of Long Island. 



It may be that the cicadas that appeared this year on a limited 

 area in the Half Way Hollow Hills, would not have come from the 

 ground until June, 191 1, if the timber had not been recently removed. 



ENTYLIA GERMAR AND ITS DIFFERENT FORMS, 



By Ignaz Matausch, 



ROSELLE, N. J. 



(With Plate VII.) 



Through the kindness of Prof. W. M. Wheeler I have come into 

 possession of a great number of specimens of Entylia sinuata — 705 

 altogether, including 119 nymphs and 12 nymphal exuviae — with the 

 data of capture. This material has enabled me to study the insect 

 in nearly all of its phases and color variations. 



The following are the data given me by Professor Wheeler : 

 " The Entylia sinuata, which I send you, were all taken September 3 

 to 6, 1910, at Colebrook, Litchfield County, Conn., on the lower sur-
