Nasutitermes sanchezi Holmgren. 



This is practically identical as regards adults with N. viorio; 

 and the soldiers are closely related. As a rule the adult is not as 

 black-winged; the ocelli are larger, slightly nearer to the eyes, but 

 there is variation in each form in this regard. 



Many specimens of this form have been examined as follows: — 

 Haiti: — (Uhler); Diquini, November; Petionville, November; 

 Port au Prince, December; Manneville, December, (Mann); Sanchez 

 River, 22-27 May (Amer. Mus.). San Domingo, (Busck). 

 Porto Rico :— (Moritz coll.); Rio Piedras (Barrett, U. S. N. M.). 

 Jamaica: — Dromilly (Hubbard coll.) queens taken from nests nos. 

 1 and 2, nests on ground; also Castleton, and Constant Springs, 

 both in early April (Hubbard coll.). The latter lots have adults, 

 typical A"^. sanchezi, but soldiers approach N. morio in having longer 

 nose and more narrow head than typical N. sanchezi. Port Antonio 

 (A. M. N. H.); Balaclava, 24 April, at night (A. E. Wight).
