1945] Notes on Neotropical PlebejincE 27 
Suprazonal portion of sedeagus of the ceraunus type but con- 
siderably longer/ asparagus-like, of even breadth throughout 
after tapering at about one third from zone. Point of surculi in 
profile of the ceraunus type but still smaller (hardly 0.01). 
Ventral spinules very minute (less than 0.005). Sagum as in 
hanno. Falx of the hanno type but larger, heavier, with the 
shoulder still less pronounced. Valve of the hanno type, with 
deeply but rather roundly carved out lower margin and a some- 
what straighter, slightly thicker rostellum. 
Measurements: aedeagus 1.22-1.24, suprazonal portion 0.75, 
subzonal 0.47-0.49 with breadth 0.1-0.14; penis 1.05-1.1. 
Furca 0.23. Sagum lobe 0.21 with breadth 0.1. Vertical/Hori- 
zontal extension of uncus: forearm 0.25/0.055-0.29/0.06, 
humerulus 0.065/0.15-0.08/0.15, shoulder 0.1/0.07, lobe 
0.21/0.07-0.23/0.06. Valve 0.62-0.65 with breadth 0.34-0.35. 
Ediinargus n.g. 
(figs, iso, n.sp, pi. 5, 7; n.sp ., pi. 8) 
Type: Lyccena isola Reakirt 1866. 
Two species known, one unnamed: 
isola Reakirt ( Lyccena , 1866, Proc. Acad. Nat. Sci. Phila- 
delphia 1866:332, “Vera Cruz, Mexico”; Hemiargus 
isola , Bethune-Baker, 1916, Ent. News 27:450); 
and a new species, 1 2 from Trinidad, British W. Indies. 
Generic Description 
iEdeagus shorter and weaker than in Hemiargus , intermediate 
in shape between Hemiargus (hanno) and Cyclargus ; much 
plainer in structure, however, than in either, with very minute 
cornuti on the similarly shaped vesica. Suprazonal sheath 
shorter than the subzonal one, weakly notched ventrally, 
acuminate laterally, with high, rather distad facing vesical 
1 This is the longest aedeagus in Plebejince except Aricia isaurica Staudinger 
which is subequal, and Icaricia icarioides Boisduval which attains the enormous 
length of 1.75. Incidentally, in Chapman 1916, l.c., the former species (pi. 29, fig. 
2, aedeagus) is wrongly figured as Albulina pheretes auct. ( orbitulus Prunner) 
and vice versa (pi. 30, fig. 4, aedeagus) . 
2 Shortly after recognizing this as an undescribed species by studying the 
Thaxter pair (see below), I learnt from Mr. W. P. Comstock that he knew it 
already from specimens (one of which he gifted to this Museum) taken on the 
same island by Mr. E. I. Huntington, and was about to publish it. I refrain from 
using Comstock’s MS. name so as not to interfere with his priority in case my 
paper appears before his.
