laterale de la tete.” In the original description of Ce- 
phalotes he writes “Premier article des antennes insere 
et loge, de chaque cote, dans une rainure laterale de la 
tete,” and in the original description of Cryptocerus — 
“Premier article des antennes s’inserant dans une rain- 
nre de la tete.” It seems obvious that Latreille con- 
sidered Cryptocerus (hidden or concealed horn [an- 
tenna]) much more descriptive of the genus Cephalotes 
(having a head) and decided to use it instead. 
Since the facts in this case are as just stated, the tribe 
receives the new name, Cephalotini , based on the type 
genus Cephalotes, which must be used for Cryptocerus of 
authors. The genera and subgenera involved, with syn- 
onymy and types, are as follows : 
Genus Cephalotes Latreille 
Cephalotes Latreille, 1802, Hist. Nat. Crust, and Ins. 
3 : 357. 
Type: Formica atrata Linnaeus. Monobasic. 
Syn. : Cryptocerus Latreille, 1803, Hist. Nat. Crust, and 
Ins. 5 : 311. 
Type Formica atrata Linnaeus. Designated by 
Latreille, 1810. 
Syn. : Cryptocerus Fabricius, 1804, Systema Piezatorum, 
p. 418 (in part). 
Emery, 1915, Bui. Soc. Ent. de France, p. 192 divided 
Cryptocerus into three subgenera: Par aery ptocerus, n. 
subgen., type Cryptocerus spinosus Mayr; Cryptocerus, 
type C. umhraculatus Fabricius, and Cyathocephalus, n. 
subgen., type Cryptocerus pallens Klug. Except for 
Cryptocerus he listed additional species in each sub- 
genus. In 1922, in Wytsman’s Genera Insectorum, fas- 
cicule 174c, pp. 306, 308, he gave a detailed description of 
each of the above subgenera, cited the same types and 
listed all the known species. 
Since Cryptocerus is not available, P ar aery ptocerus 
will succeed it. The correct arrangement is as follows:
