FIGURE 111. Hybrid #72 (dorsal, ventral). Colombia: Valle, Cali, 1973. Leg. L. Denhez? Mast de Maeght coll. (RBINS—James Mast de Maeght donated his large butterfly collection to the Royal Belgian Institute of Natural Sciences in 2015). Interpreted by Mallet et al. (2007) as a H. cydno zelinde (Fig. 105) x H. melpomene vulcanus (Fig. 102) F1, based on the larger red forewing band and partial suppression of the brown forceps on the HWV. León Denhez (and his son Leoncito?) were commercial collectors based in Cali, whose atypical Heliconius material appears not only in Mast de Maeght's collection, but also in the Holzinger and Neukirchen collections. It is likely that the locality data on the label are the source of the material from the dealer, rather than the place where the specimen was collected. This is supported by the high degree of similarity between this specimen and Hybrid #71, leading to Mallet et al.'s interpretation that the two represent crosses of the same races—the endemic race of H. cydno in the vicinity of Cali is H. cydno cydnides (Fig. 112), and there is no sympatric race of H. melpomene that occurs there. Once again, in light of the commercial origin of the specimen and the abundance of "hybrids" from this source in the collections of European amateurs, the provenance of the specimen is dubious.
