PLIOCERCUS ELAPOIDES DIASTEMUS (Bocourt) 



Pliocercus elapoides diastemas Smith, Proc. Biol. Soc. Washington, vol. 54, pp. 

 120-121, 1941. 



Seven specimens, from various localities near Escuintla, Chiapas, 

 were secured: Cerro Ovando, 6,500 feet (No. 110708) ; La Esperanza 

 (Nos. 110772-3, HMS No. 17148) ; Cruz de Piedra (Nos. 110770-1) ; 

 and Rancho Las Gradas (No. 110769). Those I observed in the field 

 were crawling about during the day. 



The Museum has two others, from Chicharras, Chiapas (Nos. 

 46437-8). 



PLIOCERCUS ELAPOIDES LATICOLLARIS Smith 



Pliocercus elapoides latioollaris Smith, Proc. Biol. Soc. Washington, vol. 54, 

 pp. 122-123, 1941 ; vol. 55, pp. 159-160, 162, 164, 1942. 



One specimen, the type (No. 110767), is from Tenosique, Tabasco. 

 The Museum has no other specimens. 



♦PSEUDOFICIMIA FRONTALIS (Cope) 



Three specimens are in the Museum, one from Guadalajara, 

 Jalisco (No. 24961), and two (cotypes) from "Colima" (Nos. 

 3 1424-5 ). 71 



♦PSEUDOLEPTODEIRA LATIFASCIATA (Giinther) 



A single specimen (No. 46550) is in the Museum, from Piaxtla, 

 Puebla. 



PSEUSTES POECILONOTUS ARGUS (Bocourt) 



Five specimens were collected, one (No. 110516) from near 

 Palenque, Chiapas, the others (Nos. 110517-20) from Piedras Negras, 

 Guatemala. 



Two of these are young, No. 110519 measuring 822 mm. in total 

 length (tail 224 mm.), the other dried and broken; both have the 

 pattern of lunulatus and in this feature do not resemble adult argus 

 in the least. This type of pattern, however, seems to be typical of 

 3 r oung poecilonotus, as it occurs in p. poecilonotus as well as in p. 

 argus, and is closely matched in the young of p. shropshirei. A sub- 

 adult of p. argus from Santo Domingo, Oaxaca (No. 46502) gives 

 evidence of the transition from the juvenile lunulatus type of pattern 

 to the adult argus pattern. 



The Museum has three other Mexican specimens, from Mirador, 

 Veracruz (No. 6373, locality open to question, as the catalog is blank; 

 this data given by a label in jar) ; mountains near Santo Domingo, 

 Oaxaca (No. 46502) ; "Tierra Caliente" (No. 7096) . The last specimen
