This classification is adapted from Ed¬ 
wards (1932), and differs from his in one 
minor modification. The writer believes 
that Edwards’ group Kerteszia should be 
elevated to a subgeneric rank, co-equal with 
subgenus Nyssorhynchus. Edwards, in a 
personal communication, has agreed with 
this contention. 
Most of these species are strictly neo¬ 
tropical, but a few species penetrate the 
area from the north and are found mostly 
at higher elevations on the Mexican 
plateau. These species are A. punctipen¬ 
nis, A. maculipennis, A. quadrimaculatus, 
A. crucians, and A. atropos. One neotropi¬ 
cal species, A. albimanus, penetrates to the 
northern limit of the area, being found in 
the lower Rio Grande valley. 
The characters of the male terminalia are 
the basis of classification of the Anophe- 
lines into genera and subgenera. It is 
possible to classify all the 27 species of the 
area under consideration into these cate¬ 
gories by noting the arrangement of the 
spines on the side-piece of the terminalia. 
The following table shows how this is done: 
Characters of Male Terminalia 
Of the genera and subgenera noted above, 
Chagasia, Stethomyia, Nyssorhynchus and 
Kerteszia are easily recognizable by the 
characters of the spines on the sidepieces 
of the male terminalia. But the subgenus 
Anopheles is divided into a number of 
groups and series, which are rather more 
difficult to separate on male terminalia 
characters. The group Anopheles contains 
two series, Anopheles and Cycloleppteron. 
In the series Anopheles, the leaflets of the 
mesosome may be variable in number of 
pairs, but all the leaflets are alike in form. 
In the series Cycloleppteron, a single pair
