Vegetable Wasps and Plant Worms.* 
The present work has for its object the bringing together of all 
known kinds of fungi that grow upon insects, and in this respect, 
so far as the English language is concerned, is unique. It is true 
that a “ Memoir ” bearing on the same subject was written thirty- 
five years ago by G. R. Gray, but, being privately printed, had a 
limited circulation. The present book will be of service and 
interest to three distinct classes — the non-scientific element, 
entomologists, and mycologists. To the first section, who do not 
wish for scientific technicalities, there is much to interest in fol- 
lowing the transition from early romance and imagination to the 
statement of modern facts, bearing on such subjects as “ Vegetable 
Wasps,” “ Beetle Hangers,” etc. 
The fungi that attack insects fall under three divisions — the 
Ascigerous, or Cordyceps group, the Laboulbeniaceae, and the 
Entomophthorese — the general features and characteristics of which 
are dealt with in the introductory portion of the book. 
Entomologists, whose main interest will be to ascertain the 
names and relationship of any fungus present on an insect, will 
find this a comparatively easy matter, as the hosts — insects — are 
arranged in systematic order, Hymenoptera, Coleoptera, etc., the 
name of the host being given in all cases where determinable. In ad- 
dition to this, woodcuts in the text and four plates facilitate matters. 
For the benefit of the mycologist, who would consider the 
entomological arrangement as artificial, there is a classified list of 
all fungi mentioned, arranged under their respective families. 
Finally, in the form of foot-notes, references to figures and descrip- 
tions, ancient and modern, are given for all the species. 
The book is well printed, and contains full indices to hosts and 
fungi. 
Trametes Trogii , Berk. — In a note in Journ. de Bot., Vol. v, p. 
356, M. P. Hariot states that, being desirous of ascertaining the 
relationship between Trametes Trogii , Berk., and Trametes hispida , 
Bagl., he wrote to Professor Mattirolo, of Turin, and to Dr. Ed. 
Fischer, of Berne, who sent him the types of these two fungi for 
examination. From a careful comparison of the specimens re- 
ceived, M. Hariot concludes that the two presumed species are 
identical in every respect, and must henceforth be known as 
Trametes Trogii , Berk., the oldest name. 
The conclusion arrived at by M. Hariot shows that he has, in 
fact, been comparing two specimens of Trametes hispida , Bagl., 
and has not seen Trametes Trogii , Berk., at all, but supposed he had, 
as one of the two specimens he received was sent as the type of that 
species.
