Phora pusilla. Perris (/. c. p. 354, pi. 5. figs. 1G2-170) redescribes tliis 
species in all its stages, figuring the larva and pupa, with details. The former 
appears to live on the “ frasa ” of Tomicus lands. In some general observations 
on the larva3 &c. of Phora (wherein he supplements Dufour’s record of 
the cornuted stigmata of the pupa), the author asserts their carnivorous pro- 
pensities. 
Phora dimidiata, Meig., is a colour-var. of thoradca, Meig. ; jiexuosa^

Peiiris (/. c. pp. 330-336), recapitulating the numerous accounts of the 
varied economy of the larvae of certain species of this family, remarks that he 
has observed a larva, having great affinity to that of Merodoiiy living in stems 
of Cirsium palustre. lie makes some interesting observations upon the earlier 
stages of Xylota and other genera, and details the act of the cornuted 
stigmata of the ‘ pupa of X. pigra being protruded through disks of the 
puparium.

Corbin (Ent. v. p. 400) records an instance of Eristalis tenax living for 
certainly 40 hours with no abdomen. 
Xylota pigra. Perris {1. c. pp. 326-330, pi. 4. figs. 112-124) redescribes this 
species in all its stages, figuring the larva and pupa with details. The larva 
lives with that of Mycetobia pallipesy under felled pine -bark, in galleries of 
Tomicus stenographus and Astynomus cedilis. The author contemplated de-
