and MijrmoMa (Smitli). The latter is referred by Smitli to the 
Mutillidae ; but Mayr thinks it belongs to the present family. 
The author recognizes 5 subfamilies of Formicidse_, which he 
names Formicidoi, OdontomachidcBj Poneridae, Borylidm, and 
Myrmicid(By the Attida and Cryptocerida of Smith being com- 
bined with Myrmicidse. The synopsis of the genera occupies 
pp. 6-26 of the work. The following is an analysis of it : — 
I. Articulations of mandibles distant ; peduncle Subfamilies. 
uniarticulate ; abdomen not constricted between 
segments 1 and 2 ; no sting 1. Formicidje. 
II. Articulations of mandibles contiguous in ^ and 
peduncle uniarticulate 2. Odontomachidje. 
III. Articulations of mandibles distant; peduncle 
uniarticulate ; abdomen generally constricted 
between segments 1 and 2, aculeate 3. Poneridje. 
IV. ^ blind ; mandibles long, with subparallel 
margins; peduncle uniarticulate ; last segment 
of abdomen bidentate; cf mandibles edentate; 
clypeus indistinct ; peduncle uniarticulate ; ab- 
domen long, cylindrical, with equal segments. 4. Dorylid^. 
V. Peduncle biarticulate ; abdomen aculeate 6. Myrmicidje. 
The Formictdcd include 24 genera, 10 of which have been proposed by the 
author. Thej^ are as follows : — 
Camponotus (Mayr), Pohjid^nchis (Shuck.), Hemioptica (Rog.), EcJmiopla 
(Smith), Colohopsis (Mayr), (Ecopliylla (Smith), Leptomyrmex (Mayr), 
Prenolepis (Mayr), Plagiolepis (Moyr), Acanthomyop^ (Mayr), Lasius (Fab.), 
Formica (Lin.), Cataglyphis (Fdrst.), Polyergm (Lat.), Gigantiops (Rog.), 
Acantholepis (Mayr), DoUchoderus (Lund), llypoclima (Mayr), Liometo- 
pum (Mayr), Iridomyrmex (Mayr), Topinoma (Fbrst,), Myrmeladmta (Rog.), 
Decamera (Rog.), and Mesoxena (Smith). 
To his subfamily Odontomachidm Mayr refers the three genera Odonto- 
machus (Lat.) and Stenomyrmex and Anochetus (Mayr), the latter separated 
upon very slight characters. 
The Poneridee include 28 genera ; and of these 9 are of the author’s pro- 
posing — namely, Trapeziopelta, Stnblognathiis, Odontoponexa, Bothroponeroy 
Diacamma, Lohopelta, 3£egaponera, Paltothyreus, and Typhlomyrmex. The 
genera of other authors referred to this group are : — Plectroctena, Pachycon- 
dyla, DrepanognatliuSy Paraponeray and Ectatomma (Smith) ; MyopiaSy Sy~ 
sphinefa, Proceratium, Discothyreay Dinoponeray Leptogorys, Platythyreay 
Gnamtogcny!^y Sysciay 3fydriumy MyopoponCy and Stigmatomma (Roger) ; 
Ponera (Lat.) ; and Amhlyopmie (Erichs.). 
The genera admitted among the Dorylidm \ — Lahidus (Jur.) and Ty- 
phlopone (Westw.), probably S and ^ of same form, as is also the case with 
Dorylus (Fab.) and Anomma (Shuck.) ; Rhogmm (Shuck.), ALnictua 
(Shuck.), and Dkhthadia (Gerst.). 
Of the 42 genera of M^jrmtctdcB, II bear the author’s, name,
