1905. ] IN THE BEETLE GONIOCTENA VARIABILIS. ddl 
at Ronda over 12 per cent. of the males, and one female out 
of 26, were classed as such. The females also differed greatly 
from the Granada population: out of 26 only 10 were green 
striped with light undersides, one was red, spotted and striped 
and intermediate, and 15 were spotted and dark below. Even 
this small collection indicates that the proportion in which the 
different forms occur varies widely according to locality, as was 
suggested by Bateson’s collections in two areas very near together 
at Granada, and the entirely different type which he found at 
Castillejo. 
The only other collections which I was able to make came from 
localities in the neighbourhood of Malaga, and these differ very 
greatly not only from those of Granada and Ronda, but from 
one another. In the first few days of April I collected on the 
hills round Hl Palo, a village on the coast some three miles east 
of Malaga. Spartiwm bushes were not very abundant and the 
collection is not large. All the beetles were obtained in an area 
not more than two miles in length, extending from near the 
sea to less than a mile inland, and nearly all were found at 
heights from 20 to perhaps 200 feet above the sea. In some 
places higher up the hills, Spartiwm was common but the beetles 
exceedingly scarce. A summary of this collection is given in 
Table IV a, and it is seen that out of 173 males 141 (81°5 per 
cent.) were of the green striped form with light undersides, the 
remainder: being mostly red, spotted with no stripes, and dark 
below. Of 204 females 187 (91:6 per cent.) were green, striped 
and light underneath, so that the percentage of this form does 
not differ greatly from that found among the males. It is im- 
portant to notice that two of the males and one female included 
in this class were pure green with no spots or stripes. It is also 
noticeable that in this locality the females were more numerous 
than males. 
During the same days I made collections in two localities to 
the north of Malaga. One of these was at a place some three 
miles up the main road, perhaps 500 feet above the sea. Here 
I obtained 322 males and 197 females (Table Va). Of the males 
with light undersides, 98 were green striped (9 of them having 
also spots), 3 red striped, 18 red spotted and striped, and one pure 
green, giving 120 or about 37 per cent. of light undersides. 
There were 16 with intermediate undersides, and the remainder 
were red spotted and dark underneath, mostly without stripes. 
Among 197 females, 52 (about 26 per cent.) were light underneath, 
all being green, and there were only two with intermediate under- 
sides. At this place, therefore, the proportions of the different 
colours were entirely different from those of Palo, although the 
two places are not more than 5 miles apart; and the percentage 
of light undersides was actually lower in the females than in 
the males. 
I also made a very small collection on some bushes growing in
