both in tlie interior valleys and ou the Pacific Coast, and for convenience 

 requires a separate name and mention.* 



15. — MECHANITIS LTCIDICE. 



Same size and shape as the typical form of Mech. Polymnia, of 

 which this is a local form or race. Its distinguishing characters are 

 three yellow belts (the first broken into two spots) which cross the 

 black apical half of the fore-wing. The basal part of the fore-wing is 

 orange tawny, and there is always a distinct and large orange tawny 

 spot near the hind angle. The black discal stripe of the hind-wing is 

 always distinct, the disk itself has a more or less distinct yellow streak. 

 The white marginal spots are always present on the undersurface of the 

 wings. 



This seems to be the prevailing form of Mechanitis in Guatemala ; 

 it also occurs in Nicaragua. 



16. — MECHANITIS DORTSSUS. 



Another local form of M. Polymnia. It differs from M. Lycidice in 

 wanting the inner yellow belt of the fore-wing, which is of the same 

 orange tawny colour as the basal part. The orange tawny portion 

 extends without break nearly to the hind angle, so that the basal two- 

 thirds of the fore-wing are of this hue, varied only by the usual costal 

 and posterior black stripes, and by the two black spots, one in the cell 

 and one between the first and the second median branches. Hind-wing 

 with the black discal stripe distinct ; disk itself not streaked with yellow. 



This form exists in company with M. Lycidice in Gruatemala. 

 Amongst the large number of examples brought home by Messrs. Salvin 

 and Godman, I have not found any connecting links between the two.f 



17.— ITHOMIA (cERATINIa) CLEIS. 



? . Same size, shape, and general coloiu' as Ith. Ninonia. Neura- 

 tion of hind-wing (?) nearly the same, the small recurrent nervule 

 being emitted rather nearer the middle of the middle discocellular than 



* * Danait Jamaicensis. i 9. Expans. 3." Much smaller than the average of D. Berenice ; spots 

 and markings the same both above and beneath ; the borders, however, are brown instead of black. 

 Ground colour pale pinkish fawny ; nervures of hind-wing bonlered with grey as in D. Strigosa. 



This is another local form ofZ>. Berenice. It was brought home in great numbers from Jamaica 

 by Messrs. Salvin and Godman; all the specimens agree in the colour and markings as here described. 



+ Mechanitis Cldinhorazona. A distinct local form of M. Polymnia. Smaller than the type or any 

 other of tlie numerous races of this species : (J . 2" 8'": 9 . 2" 10'". Its distinguishing features are (1) 

 the constant |)reseiice of a large broad yellow spot in the middle of the fore-wing, the spot possessing a 

 narrow lobe which extends between the second and third median branches towards the outer margin : 

 (2) a short yellow belt near the apex of the fore-wing; (8) the sexual diflerence in the black discal stripe 

 of the hind-wing, which in the male is always broad and distinct, and in the female invariably obsolete. 

 In other respects this form does not differ from M. Polymnia type. 



Western foot of Chimborazo, at an altitude of 3 — 4,000 feet. Sent home in great numbers by 

 Mr. Spruce, the distinguished Botanical Traveller. All the specimens agree in the distinguishing features 

 as here described, and no other form ot Mechanitii Polymnia accom|)anied them.
