XYLOPIIAGIDAil. 
Jaennicke (Berl. ent. Zeits. 1866, pp. 233-236) discusses the characters, 
habits, and distribution of the species of this family found in the neighbour- 
hood of Frankfort and in the Engadine. lie considers Bet'is clavipes (Linn.) 
to be a var. $ B.vallata (Eorst.); B. chalybeata (Edrst.) = /wsctjues (Meig.), 
The species of Suhula and Xylopliagus are reared abundantly from rotten 
wood; Ccenotnyia fcrruginea (Scop.) inhabits elevated localities, which renders 
the supposed habitat of its larva (rotten poplars) somewhat doubtful (p. 236). 
Tabanid^. 
Jaennicke has published notes on the European species 
of Tabanidce, but also including notices of several species 
from Southern Europe, and one from Algeria, in Von Heydeii^s 
collection (Berl. ent. Zeits. 1866, pp. 65-91). The total number 
of species referred to in this paper is 44, namely, of Hcematopota 
2, Hexatoma 1, Tabanus 32, Chrysops 7, and Pangonia 2. Eleven 
new species of Tabanus and 1 of Chrysops are described. 
Jaennicke states in opposition to Loew that the eyes of the 
naked-eyed Tabani present no traces of hairs, and adds that 
the colour of the axillary tubercles varies in the same spe- 
cies, and is probably dependent on age. The information 
given refers chiefly to the local distribution of the species ; but 
there are also remarks on their characters, and in some instances 
on synonymy. Thus, according to the author, T. luridus (Fall.) 
and T. solstitialis (Meig.) are varieties of T, trojncus (Linn.) ; and 
T. spodoptcrus (Meig.) is a variety of T. bovinus (Linn.). See 
also supplementary notes, /. c. p. 237.
