imagos of same species fnmi trees lliat had evidenlly been felled more 

 than one season. Acoptus stituralis may also be found in dead stumps. 

 In the following family Eupsalis mimcta breeds frequently in old stumps 

 and logs of maple, etc,, while in the Calaiidrido! I think there are un- 

 doubtedly lignivorous species. Cossonus plataha has been found by me 

 in large numbers under the the bark of a poplar which had been some 

 years dead and was partly decayed. The beetles had evidently emerged 

 from the wood, which was penetrated by numerous small holes. Rhyn- 

 coltis and Stenoscelis of this family also apparently breed in dead wood. 

 I have taken specimens of 6'. brevis both from old poplar and from 

 maple stumps.

Society News. 



Brooklyn Entomological Society, March 3d. Twenty-six members and 

 visitors present, the President Mr. Cramer in the chair. The reports of the oi3&- 

 cers for 1884 were read and approved. Mr. A. Salle of Paris, France; Baron C. 

 R. von Osten-Sacken, Heidelberg, Germany; and Dr. John G. Morris, Baltimore, 

 Md., were on metion of Mr. J. B. Smith elected honorary members of the 

 Society. Prof. C. V. Riley of Washington, D. C, was elected a life member. 

 Mr. A. E. Brunn was nominated for membership by Mr. E. Ii. Graef, and Mr. 

 W. H. Danby of Brooklyn, and Mr. Eugene M. Aaron of Philadelphia were no- 

 minated for membership by Mr. John B. Smith. 



On motion, the Secretary was instri;cted to offer to the Agassiz Association 

 the aid of the Society in the way of determinations and in such other ways as 

 might best further the ends of both Societies. 



Mr. Smith introduced Dr. Horn o"f Philadelphia, honorary member of the 

 Societj', and Dr. S. W. Williston of New Haven, who had come on to attend the 

 meeting of the Society. Dr. Williston was invited to sit as a corresponding 

 member of the Society. 



Mr. Smith described a monstrosity of a (^ Lucanv.s cervus, the left mandible 

 of which was modified into an imperfect $ head. 



Dr. Horn gave a short account of several monstrosities known to him, and 

 stated that the LamelUcornia were especially rich in monstrosities. The antenna? 

 were very often the subject of abnormal variations. Frequently there would be 

 an unequal number of joints in siJecimens of the same species, or even in the 

 same specimen. The Carabklaj stood next in the order of frequency. This led 

 him to speak of variations of color and sculpture, and their value in systematic 

 work. The sexual organs of the ^f are among the most absolutely invariable 

 structures, and are the most reliable in the separation of species among the Sta- 

 phUinkke. Mr. Smith gave it as the result of his studies in the Xodnkkv that the 

 genitalia of the (j' afforded the be.st possible sj^ecific characters, in the species 

 of Mamesira esijecially, every species nearly has a very distinct and peculiar 

 structure. Identity of type always indicates close relationship, while identity of 

 form in his experience, proves specific identity, no matter how much maculation
