 On the species of Canthon and Phanaeus of the United States, with notes 



on other genera, by Frederick Blanchard. Tr. Am. Ent. Soc. XII, pp. 163 — 172, 



May 1885. 



We are glad to see Mr. Blanchard in the ranks of our systematic 

 workers. He has been long and favorably known as a collector, and his 

 paper gives evidence that he is able to do good work in the systematic line. 

 The Periodical Cicada. An account of Cicada septendecim and its tiedecim race, 



with a chronology of all broods known, by Chas. V. Riley, Ph. D. Bulletin No. 8,

 stribution of the two broods due this year, and stating that notes of the 

 appearance, the numbers and distribution of the broods are desired. It 

 would be a desirable thing for all Entomologists to gather what infor- 

 mation they can in reference to these insects if they appear in their locali- 

 ties and send the same to Prof. Riley.

Horn, M. D. Tr. Am. Ent. Soc. XII, pp. 85—106. PI. I and II. (Feb. 1885.) 

 Dr. Horn here gives us an exceedingly interesting paper, illustrating 

 some remarkable peculiarities of structure. These were touched upon 

 in the March Meeting of the Brooklyn Entomological Society, and are 

 here elaborated. Of many species there are three forms of structure of 

 the 4th ventral segment of the $. One is called a perfect <$, another 

 an imperfect ^, the third an incomplete $. These are but descriptive 

 terms and are not applied to differences of function. It is however an 

 exceedingly interesting question whether these differences in structure
