814 Prof. Westwood on the supposed abnormal 



4to, 1844, p. 171) has given a revision of the genus 

 Eiirijtoma, in which the divisions and subgenera proposed 

 by Walker and Forster are rejected, and objecting to the 

 supposed phytophagous character of some of the species, 

 as proposed by Nees v. Esenbeck; all the species 

 observed by him being asserted to be parasites, some 

 of them being even supposed to be parasites on the 

 parasites {Schmarotzer — Schmarotzer) of the gall-fly or 

 other insects from which they have been observed to 

 have originated. Moreover, he gives instances of the 

 polyphagism and even pantophagism of some of the 

 species, several of which are parasites on wood-boring 

 Coleoptera of the genera Hijlesinns and Eccoptogaster, as 

 well as upon Nemati, Sapenhe, and Magdalis. 

 The species described by Dr. Eatzeburg are : — 



1. E. signata ' Wahrscheinlich der Haupt-Eichen- 

 Gallenschmarotzer unter den Eurytomen.' 



2. E. Jiavovaria,n. &. Fourteen male specimens reared 

 from Hylesinus fraxini from Upper Silesia. 



3. E. Jiavo-scapularis, n. s. Also parasitic on Hyle- 

 sinus fraxini. 



4. E. Ahrotani. 



5. E. verticillata, Nees. 



6. E. eccoptogastri, n. s. From a " kranken apfel- 

 zweigen " in which Eccoptogaster rugtdosus, Saperda 

 2)r(ei(sta, and a Magdalis were found. 



7. E. ahieticola, n. 8. From " Fichtenkniippeln " in- 

 habited by Magdalis violacea. 



8. E. ischioxanthus. Obtained with E . Jiavovaria horn. 

 Hylesinus fraxini. 



In the second volume of the same work, 1848 (p. 177), 

 Dr. Eatzeburg has added the descriptions of three 

 additional species of Eurytoma : — 



9. E. aciculata. Obtained both males and females 

 from " Weidengallen " and from Salix viniinalis, pro- 

 bably being parasitic on Nematus angustus. 



10. E. striolata. From Eccoptogaster intricatus. 



11. E. costata. Males obtained from cocoons of the 

 Microgaster of Pontia cratcegi. 



And in the third volume of the same work, 1852, 

 p. 220, four more species of Eurytoma are described : — 



12. E. extincta. Parasitic on Nematus angustus. 

 "Von Hrn. Brischke aus dem Stiele der Weidenrosen
