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 

 Oastillejo. 



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. S])artiimi bushes were not v^eiy 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, Spartmm was common but the beetles 

 exceedingly scarce. A summary of this collection is given in 

 Table lY <», 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 fi-om 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 percent.) 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
