a collection of Heliconine forms from French Guiana 415 



melanippe, the latter a rare form in which only the yellow 

 thelxiope group of spots remains on the fore-wing. It is 

 figured by Oberthiir (Etudes d'Ent., xxi, PL 5, fig. 58). 

 Of melpomenides (figured by Oberthiir, loc. cit., PL 4, fig. 46 

 and PL 5, fig. 50) there are eighteen specimens, and barely 

 half the number of true melpomene, viz. eight. Of primus 

 which we figure (PL CVII, fig. ] ) there are only two speci- 

 mens, with some seven intermediates graduating to typical 

 melpomene. Of lucinda there are also only two specimens 

 that are typical, but there are some eighteen intermediate 

 forms to lucia. Of collis which we figure (PL CVII, fig. 3) 

 there are but three typical forms with the intermediate 

 specimens to melanippe. The whole can be grasped better 

 in tabulated form.

Section B {hind-wing with red basal streak). — Of the 

 forms with a short red basal streak to the hind-wing there 

 are 420 specimens. These have the streak of variable 

 size, some showing a suffusion over the lower and outer 

 half with black scaling. But the hind-wing red markings 

 are discussed later. The 420 specimens in this section 

 divide up mainly into three principal groups— (1) The 

 diana, dianides group; (2) the deinia, faustina group; 

 (3) the cybele group. These contain the following numbers 

 of examples each— (1) 89, (2) 79, (3) 51. Both diana
