ZOOLOGICAL LlTEllATURE. 
of tliis family, in which he recognizes 3 genera, including 10 
known species. He remarks on its near relationship to the 
TermitidcB and also to the PsocidcB, the latter manifested espe- 
cially by Embidopsocus, ‘‘ a true Psocus with the facies of an 
Embia and the wings of a Termite.^^ Olyniha staphilinoides 
(Walk.) is the larva of a Forficula, 
Hagen (Stett. ent. Zeit. 1806, p. 283) mentions that he has the larva of an 
Emhia from Spain. It appears to belong to B. solieri (Ramb,). 
PsOClDiE. 
Hagen (Stett. ent. Zeit. 1866, pp. 188-196 and 233-244) has 
subjected the synonymy of the described species of this family to 
a careful revision, in which he takes up the works of different au- 
thors in chronological order. His results may be stated as fol- 
lows : — 
Linn4 describes 8 species of Psocidce under the following names : — ■ 
Hemerobius sexpimctatus, Jiavicans^ hipunctatus, pediculariuSy cniciatus, Phry- 
ganea saltatrix (uncertain, but probably nearly allied to P. hifasciatusy 
Steph. = ^-mamlatus, Lat.), Termes pidsatorhmi (probably = Clothilla stu- 
diosa, Westw.) and fatidicum {■=.Atropos ptdsatoria, auct.). Linne’s Cynips 
fagi (S. N. i. 919) is also said to be a Psocus. Schrank’s Hemerobius 
aphidioidcs=i Psocus immunis (Steph.). Fabricius describes some Linnean 
species, and also the following as" new: — Hemerobius striatidus {—Psocus 
stigmaticusy Latr.), ahdominalisy Syst. Ent. (probably = jlamcanSy Linn.) ; 
abdominalisy Ent. Syst. (=pedictdarius, Linn.) ; longicornis (=lineatuSyljsdr.), 
fasciatus, Arpunctatus {—cruciatuSy Linn.), variegatuSy picicortiis. 0. 
F. Muller describes 6 new species, of which Hemei'obius nemoralis is unhnown 
to the author, II. unipunctatus = aphidioides (^chx.)ytrifasciatus=i 
fasciatus (Fab.), pw6’^7/^<s is probably a species of CexciliuSy longicornis— longi- 
cornis (Fab.), gihbus probably= bymnctakis (Linn.), and Termes divinatorium 
^Atropos pulsatoria (auct.) (Linn.). Latreille, who established 
the genus Psocus, and afterwards formed a distinct family for these insects, 
described several new species, namely Psocus ciliatusy morio, A-maculatuSy 
fuscopterus (probably Balm.), bifasciatus (not determined), lineatus 
longicornis y Fab.), and pilicornis (probably Fab. c5'). Stephens 
(Illust. Brit. Ent.), following Leach in dividing the Psocidce into the 2 
genera Psocus and AtropoSy describes 42 species of the former genus, which 
Hagen regards as reducible to about 20, and 2 species of Atropos — A. pulsa- 
torius {=divinatornimy Mull.) and A. fatidicus (not determined). The syno- 
nymy of the species of Psocus described by Stephens is considered by Hagen 
to be as follows : — P. pilicornisy atomariuSy picicornis, fascicdus, and variegatus 
— variegatus (Fab.) and perhaps partly fasciatus (Fab.) ; P. maculatus and 
subfasciatus^sexjnmctatus (Linn.) (5* P.lineatus=longicoi'nis (Fah.)-, P.ne- 
bulosus and similis= cf and $ of one species ; P. bifasciatus y contaminatuSy and 
megasligmus— d-macidatus (Lat.) ; P. subnebulosusy not determined ; P. im- 
munis and lo7igicornis= (S and $ of one species (Jd(imb.)= obliter'ata

P. ochroptef'us, Jiavidus, Jiavicans, and obsoletus = borecllus (Zett.) = flavidus
