de V Antille St. Vincent. 399 
Genre CREMASTOGASTER, Lund. 
Observed at the southern end of the island; thickets 
along the seashore, or near it. In this region the 
ants were very numerous on the ground, tree-trunks, 
and foliage. The females, generally two to four or five 
together, and attended by many workers, were found in 
crevices under the outer bark of Manchioneal and Land- 
box trees; each little nest was two or three inches long, 
and perhaps an inch broad, but many were on the same 
tree, and perhaps formed part of the same great colony. 
The females are very sluggish, and when the nest is 
uncovered generally cling to the bark of the tree by their 
jaws; the workers are active and pugnacious. There 
were many larve in the nests, but I could find no males. 
Apparently the passages of the formicarium are short, 
and confined to the outer bark of the tree. 
1. Cremastogaster curvispinosa, Mayr. (No. 7b et 7c). 
3, var. antillana, n. var. 
Différe de la forme typique de l’Amérique dusud par l’échancrure 
méso-métathoracique moins profonde, surtout lorsqu’on la regarde 
de dessus. Cela provient de ce que le métanotum est moins élargi 
de cété. Les épines métanotales sont beaucoup plus courtes, et 
moins divergentes tout en ayant la méme conformation et le méme 
poil caractéristique vers la moitié de leur longueur. Les épines 
sont longues comme la moitié de l’intervalle de leurs bases-environ 
(presque comme l’intervalle entier chez la forme typique). 
(7b). Richmond Estate; open valley near sea-level ; 
in a rotten stump. Ants numerous, in a cavity about 
3 in. X $ X4, with larve, but I could find no female by 
careful search. Perhaps another species. 
(7c). Forest, Morne a Garou, 1500—2000 ft. Nov. 1st. 
Beaten from foliage. Apparently rare in the forest. 
2. Cremastogaster brevispinosa, Mayr, var. minutior, 
n,\var., (No: a, 7 d-eb. 199 bis). & et 2. 
8. L. 2,242, 6 mill. Epines plus courtes encore que chez le 
type, un peu courbées en avant. Stries du pronotum et de la face 
basale du métanotum assez peu apparentes et assez éparses; entre 
deux ces parties sont réticulées. Mésonotum assez rugueux-striolé,
