Nasutitermes sanchezi Holmgren. 



This is practically identical as regards adults with A'^, morio; 

 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 N. sanchezi, but soldiers approach N. morio in having longer 

 nose and more narrow head than typical A^. smichczi. Port Antonio 

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