 Grabham and Mr. Cockerell. It has not yet been determined whether It

 mentions particnlarly a Lepidopterons enemy of Ceroplastes which Mr. 

 Cockerell thinks may be a species of Thalpochares, a Chrysopa, and a 

 Chalcidid parasite of a Lecaninm on Terminalia. 



EECEXT E>'TOMOLOGICAL PrBLICATIOXS BY THE V. S. NATIONAL 



3irSEUM. 



Since we last mentioned the publications of an entomological nature 

 emanating from the 17. S. National Museum, there have appeared in 

 addition (1) Directions for Collecting and Preserving Insects by C. Y. 

 Eiley [Part F, Bulletin 39] ; (2) Eevision of the Geuus Cucullia ; Ee- 

 vision of the Dicoj)inie; Eevision of Xylomiges and Morrisonia, by 

 John B. Smith (Xos. 890-892). and (3) Insects of the subfamily En- 

 cyrtinie with Branched Anteumie, by L. O. Howard [Xo. 905]. 



GALLS IX GER3IANY. 



Dr. D. H. E. von Schlechtendal's important contribution to science 

 entitled "Die GaUbildungen (Zoocecidien) des deutschen Gefasspflan- 

 zen" has reached us under separate cover, extracted fi^om the Jahres- 

 bericht des Yereins fdr Xatm^kunde zu Zwickau, 1891. The plan of 

 this work comprises an arrangement of all the galls jDroduced by ani- 

 mals known in Germany, according to the botanical classification of the 

 plants which bear them. Under each plant species is given a synopti- 

 cal table of its galls, running to the name of the gall insect, wherever 

 this is known. The work is of the greatest value to students of insects, 

 but it is surprising to notice how large is the number of cases in which 

 the creature producing the gall has not been reared, or at least not spe- 

 cifically determined. When this is the case with a country like Ger- 

 many, the fauna of which is so well knowu, American students need not 

 feel ashamed of the condition of our knowledge in this direction. The 

 number of the distinct galls runs up to 1.322. The work covers 114 

 pages and is well indexed, l)oth zoologically and botanically, according* 

 to the families and genera in botany and genera and species in zoology. 

 Mr. Ashmead's synopsis of the Cynipid Galls is the only approach to a 

 work of this character which we have in this country.
