elsewhere described j P. 4,-maculatus is represented by specimens of phceo- 
pterus and Jlaviceps ; P. striatulus and Jlaviceps form one species ; P. immacu- 
latMS, rtifescensy and Jlavescens constitute one s^QCiQS—suhfumipennis (Zett.) 
—stri(josus (Brauer); P. 4,-punctatus, costalis, and svhocellatus — cruciatus 
(Linn.); P. subpunctatus probably (Steph.) ; P. viaculijyennis, 
not identified ; P. nigricornis and phcRopterus form one species ; P. nigri- 
cans and ahdominalis and probably duhius=pedicularius (Linn.). Of the 
species referred to by Curtis several are identical with Stephens’s : his 
P. pilicornis=fasciatus (Fab.) ; P. variegatus — nehulosus (Steph.) ; Ccscilius 
fenestratus — vittatus =fuscopterus (Lat.) ; C. strigosus —Jlavidus 
(Steph.); C. irroratus= Jlaviceps (Steph.); C. vitripennis=iimmunis 
as also probably C, longicornis\ C. morio probably=monb (Lat.). Curtis’s 
collection contains a Psocus vittatus— immaculatus (Steph.), P. striatus=P. 
phceopterus (Steph.) and P. ochropterus, a species allied to ^-niaculatus. 
Westwood’s ClothUla studiosa=i T. pulsatorium (Linn.); he also established the 
genus Lachesilla. Burmeister recognizes only 3 genera of Psocidce, — Troctes 
■=Atropos and Lachesilla ^ Psocus^ Psocus and Ccecilius, and Thyrsopliorus 
(g. n.). Burmeister’s 2 species of Troctes probably belong to the common 
Atroiws. Of the species of Psocus cited by him, P. st7'igosns— immaculatus 
(Steph.), pedicularius is new, domcsticus— pedicular ius (Linn.), lasioptcrus is 
probably new, longicornis—inimunis (Steph.), fencsU'atus— vittatus (Balm.), 
pilicoriiis — variegatus (Fab.) cf , 4t-macidatus=4c-maculatus (Westw.), nei'vosus 
probably=yhsc*«^ws (Fab.). Thyrsopliorus includes T. speciosus and penni- 
coi'tiis, from Brazil. Hagen remarks that Burmeister’s first division of the 
genus Psocus is not equivalent to Ccecilius (Curt.). Bambur describes a 
Thyrsopliorus sjunolce^speciosus (Burm.), Psocus affinis and infuscatus—nehu- 
losus (Steph.), P, naso = imnmnis (Steph.), P. microphthalnius = venosus 
(Burm.), P. subfasciatus and P. obscurus probably new, P. conspu7xatus=^4^- 
maculatus (Westw.), P. binotatus—27edicula7diis{Jjmi\.)) P. licdicularius 
lucifugus are not determined by Hagen. Walker recognizes the genera 
Thyrsophorus, Psocus, Atropos, ClothUla, and Lepinotus. Of Thyrsophoi'us he 
describes 6 species, reducible to 3, his T. anticus alone being distinct from 
Burmeister’s species. In the genus Psocus 61 species are cited ; the syno- 
nymy of many of these coincides with that given for the Stephensian species, 
but his P.piilicornis— vittatus (Balm.), 7nagnus— venosus (Burm.), venosus — ini- 
maculatus (Steph.), pupillatus—alboguttatus (Balm.). Of Zotterstedt’s spe- 
cies, P. subfasciatus = bifasciatus (Latr.), obliteratus = aphidioides (Schr.) = 
naso (Ramb.) = ^w^m^^M^5 (Steph.), sub fumipe^inis— immaculatus (Steph.), as 
also probably boreellus — jlavidus (Steph.), and striatus probably 
—borellus. Hagen also indicates the recent memoirs in which new spe- 
cies have been described, and states that the number in his collection is 
about 116. 
Hagen has also published (Verb. zool. -hot. Gesellsch. in Wien, 
xvi. pp. 201-220) an alphabetic synonymic synopsis of the ge- 
nera and species of this family, on the same plan as the synopsis 
of PhryganidcE published by him in 1864 (see ^ Record,'’ 1864, 
pp. 562, 563) . He admits 136 species as belonging to the group, 
referred to 21 genera, which he tabulates as follows (/. c. 
p. 203)
