48 _ Observations on Cicindelide. [ZOE 
e 
From the above propositions, it is to be argued that /atisignata 
has been evolved from /enuicincta, the latter being naturally and 
logically the fundamental species, the former only so by the ar- 
bitrary laws governing the priority of nomenclature. 
Latisignata may be regarded as an incipient species in progress 
of divergence from a more normal type, and will in all probability 
in the course of time become isolated and perpetuated. 
At the present time the two forms are to be considered as ident- 
ical. 
Any collector of these insects cannot fail to note the following 
facts while in the field: 
1. That the two forms under consideration form the extremes of 
a series, in which the intermediate types of elytral variation are ex- 
ceedingly abundant and exhaustive. 
2. That the normal /enwicincta in numbers considerably exceed 
the broad-banded form, the latter being comparatively scarce. 
3. That all of these forms are intimately associated. 
4. That eight-tenths of the couples taken zz cotfu will represent 
a Sor 6 of one of the extremes, with the opposite sex an inter- 
mediate. 
From the above can be seen that they interbreed entensively, in- 
habit the same geographical region, and exist under the same en- 
vironment and climatic conditions. 
If any one of the forms inhabited a more or less distinct geo- 
graphical district, so that it would be possible to admit of different 
climatic influences and environment, without constant interbreeding, 
the idea of races could be sustained. 
Correctly and philosophically speaking, Cicindela tenutcincta is 
a fundamental species, with a strong tendency towards variation. 
Cicindela obliguata Kirby. Occurs upon the borders of the Big 
Laguna, in Temecula Valley. 
Cicindela vibex Horn. Ocean beach, near Oceanside. 
Cicindela guttifera Lec. According to Schaupp’s “‘ Synopsis of 
the Cicindelide,’’ this is the form that occurs throughout the 
county, about all the inland streams and ponds, as well as upon the 
ocean beach. In r2-gut/ata the elytral markings are broken into 
spots. Specimens of gw#fifera taken in Arizona are quite green. 
This color begins to be perceptible in the specimens collected in the 
central portion of the county, becoming deeper as we approach the 
desert region and Colorado valley.
