laterale de la tele.” In the original description of Ce- 
phalotes he writes “Premier article des antennes insere 
et loge, de chaque cote, dans nne rainnre laterale de la 
tete,” and in the original description of Cryptocerus — 
“Premier article des antennes s’inserant dans nne rain- 
ure 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. umbraculatus Fabricius, and Cyathocephalus, n. 
subgen., type Cryptocerus pallens King. 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, Par aery ptocerus 
will succeed it. The correct arrangement is as follows :
