remaining plates are to appear. The author reproduces Sichehs 
instructions from the ^ Guide de FAmateur dTnsectes/ and 
gives a general outline of the economy of Anthophora and its 
parasites. He includes in his work Habropoda (Smith), Antho- 
phora, and Saropoda, and describes about 45 new species. 
Much of the practical part of this work is avowedly owdng to 
the late Dr. Sichel, with whose extremely synthetical views, 
however, the author does not appear, from his prefatial remarks, 
entirely to agree. From the copious records of varieties (*^ Tribes*^ 
of vars. being employed !) and of undefined conditions termed 
5w6varieties, it is not always easy (bearing in mind the reserve 
of opinion above mentioned) to be sure as to the true status 
of the insects described.

parasitic on Odynerus spinipes. Ent. Monthly Mag. vi.

This paper contains more than is implied in its title ; and the 
account of the habits of these insects is both minute and instruc- 
tive. The Chrysides in question diVQ neglect a (Shuck.), 
(Linn.), bidentata (Linn.), and ignita (LinUv). Of these, neglecta 
and bidentata are the habitual parasites of the Odynerus, the 
other two only occasionally.
