Distribution : Known only from three localities. Morelos: Huit- 
zilac (known as Tres Marias until 1930, according to J. Hendrichs, 
in litt.) ; Zempoala National Park (Bolivar, May, 1940, in coll. 
Bolivar, I.P.N., Mexico). Michoacan : “1.1 mi. S. Angahuan, corn- 
field, edge of lava flow, 7300'”, August 14, 1967 (Ball, Erwin, and 
Leech, in coll. G. Ball, University of Alberta, Edmonton, Alberta, 
Canada). At Zempoala, which is about 7 kilometers west from 
Huitzilac, the beetles occurred in a forest of Abies and Pinus at an 
elevation of 2800-3000 meters. The village of Huitzilac, located 
at kilometer 53 on the Mexico City-Cuernavaca highway, is near 
an old volcano (Tres Cumbres) with three peaks which overlooks 
the valley of Cuernavaca east of the village. The Wickham specimens 
in the Casey collection were probably collected around this mountain. 
Agonum (Platynella) jnontezumae (Bates), new combination 
Figures 1, 4A, 4B, 4C 
Anchomenus montezumae Bates, 1878, p. 593 ; type from vicinity of Mexico 
City, in British Museum (Natural History). 
Platynus montezumae: Bates, 1882, p. 92, pi. 4, fig. 24. 
Laemostenus ( s . str.) montezumae: Csiki, 1931, p. 812. 
Length of six specimens 9.3-13.6, mean 11.6 mm. Color and gen- 
eral form as in districtum but a little more slender, humeri more 
sloping away from the base. Eyes larger, their diameter equal to 
either length of scape or length of tempora behind. Pronotum similar 
but margins much less strongly reflexed. Elytral apices feebly pro- 
duced, rather blunt, not sharply angulate as in districtum. Aedeagus 
of a specimen from Esperanza (Puebla) 1.60 mm. long, a little 
smaller and less arcuate than in districtum , basal bulb not distinctly 
narrower than median lobe. 
Distribution: The three localities from which Bates (1882) 
reported this species are (1) “near the capital (Flohr)”; (2) 
“Cumbre del Pelado, San Antonio de Arriba (Salle)”, approximately 
kilometer 37 on the Mexico City-Cuernavaca highway ( J. Hendrichs, 
in litt.)', and (3) “Esperanza (Hoge)”, presumably in the state 
of Puebla. I have seen specimens from the last two localities. Pro- 
fessor Ball’s material (in coll. G. Ball, University of Alberta, Ed- 
monton, Alberta, Canada) includes three specimens from “Tlachi- 
chuca, Puebla, 8300'”, May 29, 1966 (Ball and Whitehead); and 
two specimens from the Cofre de Perote, “N. slope 10.0 mi. S. Las 
Vigas, 9600'”, August 24, 1967 (Ball, Erwin, and Leech). The 
Tlachichuca “specimens from the vicinity of Mt. Orizaba were col- 
lected in a cornfield” (G. E. Ball, in litt.).
