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 El Palo, a village on the coast some three miles east of Malaga. Spartivm 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, Spartium was common but the beetles exceedingly scarce. A summary of this collection is given in Table IY «, 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 important 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 V a). 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 undersides. 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 |
