Cordulegaster, formerly united, can no longer be included in 

 the same family. 



The immature states of Ascalaphus and Myrmeleon have 

 been described by the curator, and contain 37 species in 

 about 20 genera, two-thirds of them new to science. Mr. 

 Konopicky, from Vienna, attached as artist to the entomo- 

 logical department by order of Prof. L. Agassiz during his 

 absence from Cambridge, has figured the larvae, nymphse, 

 cocoons and eggs, so far present in the collection, with 

 superior finish, and the volume containing these drawings is 

 really a valuable addition to the illustrations in the Museum 

 library. It is intended shortly to publish the whole family 

 of the Hemerobina in the Illustrated Catalogues. For the 

 remarkable monographs of North American Lepidoptera by 

 Mr. W. H. Edwards, in Coalburgh, W. Va., Mr. Konopicky 

 has figured a number of eggs, caterpillars and chrysalids from 

 the living specimens, to be published in the forthcoming parts 

 of this work. Some scientific work was completed by the 

 curator either for the benefit of correspondents of the Museum 

 or in consequence of new publications. The Cordulinte of the 

 Museum were sent to Baron De Selys Longchamps in Liege, 

 Belgium, and are published in his synopsis, forming an addi- 

 tion of about one-third of the species. The Ascalaphina 

 were compared and studied after Mr. McLachlan's monograph, 

 the Ephemerina after Mr. Eaton's monograph, and both fam- 

 ilies arranged upon the basis of this new knowledge. A 

 monograph of the interesting genus Pteronarcys was given, 

 and a scientific review of the Pseudoneuroj)tera and Neurop- 

 tera of T. W. Harris's collection made ready for publication. 

 The Lepidoptera of Texas were sent to Prof. Zeller, in 

 Stettin for publication. The Noctuina, Geometrina, and a 

 part of the Micros are just published by him, and the Texan 

 Tineina by Prof. H. Frey, in Zurich. The Texan Hemip- 

 tera are in the hands of Mr. Ph. R. Uhler, in Baltimore, for 

 publication. The Hymenoptera from Texas are finished for 

 publication by Mr. E. T. Cresson, in Philadelphia, and re- 

 turned to the collection. The Coleoptera from Zanzibar are 

 published by Dr. Gerstaeker, in Berlin, and returned to the 

 Museum. 



Mr. Hubbard finished the scientific determination and
