322 INSECTA^ HYMENOPTERA. 
describes and figures a species parasitic on Aranea inquilina, Clk., and dis- 
cusses its economy, 
Myzine. Instances of sexes being generically separated are recapitulated : 
M. cylindrical Pz., and Tvphia glahrata, F., are added as being sexes of the 
same species j the characters of the genus are discussed, and it is suggested 
that Myzine should be dropped and IHesiaj Jur., adopted ; Gerstiicker, S. E. Z.

Gerstacker, S, E. Z. xxxiii. pp. 254-269, discusses at great length the affi- 
nities of J)orylus and J)ichthadia, chiefly from the analogy afforded by the 
real or supposed relations of the former with Typhlopone and Anomma. His 
observations are of considerable physiological interest, but incapable of satis- 
factory abstraction.

Gustav Mayh, SB. Ak. Wien, Ixi. (1870) pp. 370-417, pi., under the 
title “ Formicidce Novogranadenses,*’ describes 101 species from New Granada 
(including 43 new, and 2 new genera), which he considers to be probably 
one half of the number existing in that district. Of those already known, 
some have been recorded from Mexico, the Antilles, Panama, Brazil, tho 
Argentine Republic, and elsewhere in South America; others occur from 
Mexico to Brazil ; and Prexxolepis longicornisj Odontomachus hcematodes, Tetra- 
morium guineense, and Sulenopsis geminata are considered to be cosmopolitan. 
In addition to portions of various new species, the author figures parts of 
Camponotus pellituSy Mayr, small worker, fig. 1, and HypocUnea abrnpta, 
Smith, fig. 9. The following observations occur: — Camponotus atricepSy Sm., 
and C. esuriensy Sm. (vidpinuSy Mayr), are corroborated as one species, of 
which fidvaceusy Norton, ex typ., is a colour variety, and tceniatuSy Rog., is 
the 5 ; C. JiexuSy Mayr, = cmss^^s, small worker; Formica abruptUy Sm., is a 
Jlypoclineay but erroneously referred by Roger to II. bidens, L . ; Prenolepis
