This differs from the Cuban form (E. dina dina) in the 
complete absence of a black border on the hindwing, and in 
the greater extent of the apical black patch of the forewing. 
Our specimens agree very well with Butler’s description 
and figure. 
Eurema helios mayobanex subsp. nov. 
$ . Wings above uniform orange, with a fine black border 
on the hindwing and a conspicuous border on the forewing, 
about the same as in the Cuban dina. Under side immacu- 
late orange except for a minute double cell spot on the 
hindwing. 
9 . Deeper orange toward the edge of the wings ; no 
black margin to hindwing ; apical border of forewing brown 
rather than black. Under side with a reddish patch at apex 
of forewing, and another on the margin of hindwing be- 
tween veins Rs and M x ; some scattered purplish spots on 
disc of hindwing. Length of forewing, 20-22 mm. 
Type (^) and paratypes (2$ $ , 1$) from Haiti: 
Ennery (2500 ft., Aug., Bates). 
This form may be distinguished from dina (s. s.), 
parvumbra or memulus by the dark orange ground color of 
both sexes, and from helios by the comparatively broad 
apical border of the forewing. 
The “distal process” of the male genitalia of mayobanex 
(Klots, 1928 for terminology) is about twice as wide as in 
memulus , and the various lobes are much more strongly 
developed in the former species. The genitalia of two 
specimens of mayobanex and of one of memulus were 
examined. 
The four specimens of mayobanex and the Ennery speci- 
men of memulus were all caught on the same day, as were 
specimens of Eurema lisa and E. proterpia. 
Kricogonia castalia (Fabricius) 
In the M. C. Z. there are 21 $ $ , 7 $ $ from : Haiti : 
Cabaret (Aug.) ; Mont Rouis (Aug.) ; Mt. Bourette, La 
Selle Range (5000 ft., Sept.); Cap Haitien; Rep. Dom. : 
Bonao (Aug.) ; Saona Is. (Jan.). 
The pattern variation of this species seems to show no
