banks: antillean isoptera. 483 



2. Eyes smaller; seen from side plainly much more than diameter from vertex; 



smaller species creolina. 



Eyes larger; seen from side hardly diameter from the vertex 3 



3. Pronotum obliquely narrowed on sides; more than twice as broad in front 



as long; antennae pale yellowish ripperii and pilifrons. 



Pronotum rounded on sides, and not so much narrowed behind ; not twice 

 as broad in front as long; antennae more brownish lividus. 



The winged specimens of several species are extremely close, and 

 I shall not try to tabulate these; in the case of A'^. viorio and N. 

 sanchezi, it may be that they are all one species. 



Nasutitermes pilifrons Holmgren. 



The adult taken with the hairy, dark-headed nasuti of Jamaica 

 is practically identical with N. ripperti, and if the soldiers did not 

 differ in color I should consider them the same species. The eyes 

 are more circular, the ocelli usually more circular and a trifle smaller, 

 and the vertex is more apt to be shining, the wings are rather more 

 yellowish, and fewer long hairs on the head. The soldier described 

 by Holmgren is very close to A^. cuhanus, except in color. 



Jamaica: — Hubbard took queens with soldiers in nest 3 at Drom- 

 illy, in April. Also at Constant Springs, 5 April; Port Maria, April, 

 and Kingston (Maxon, U. S. N. M.) Port Antonio, and Hope Gardens, 

 22 February (Grossbeck, A. M. N. H.); Balaclava, 20 April, at night 

 (A. E. Wight). It makes nests in trees. 



Described from Curasao, West Indies, and also known from Pan- 

 ama; probably does not occur in the same islands as N. ripperti. 



Nasutitermes ripperti (Rambur). 



The pale area between median and cubital vein is distinct near 

 base, but beyond is faint or absent? The pronotum is pale yellow, 

 in strong contrast to the reddish brown head. The eyes are plainly 

 elliptic, longer in a diameter toward the upper part of face, the large 

 ocelli close to the eyes, slightly elongate, and about one and one half 

 to one and one third diameter from the front margin of head. The 

 head is clothed with fine, appressed, whitish hair, and a few scattered, 

 longer, erect hairs. 



The soldier is described by Holmgren as E. cuhanus and E. balm-
