67. Myrmelachista kraatzi Roger. 

 Berl. ent. zeitschr., 1863, 7, p. 163 S . 



Gundlach says that this species was taken near Cardenas. There 

 are no specimens in his collection and his note-book contains the 

 phrase: — "se perdio por la muerte de Roger." 



68. Myrmelachista rogeri Ern. Andre. 

 Rev. ent. 1887, 6, p. 288 S . 



This species, which has never been taken since it was described by 

 Andre, seems to be very similar to M. kraatzi, but differs in its darker 

 color and the shape of the petiole which, to judge from the descrip- 

 tions, is inclined forward and less compressed anteroposteriorly. 

 The locality given by Andre is simply " Cuba." 



69. Camponotus santosi Forel. 

 Verh. Zool. bot. gesellsch. Wien, 1908, 58, p. 408 8 . 



The type specimens of this species, which belongs to the maculatus 

 group, were received by Forel from Dr. Santos without precise lo- 

 cality. I have seen two colonies of this ant, one under a stone in a 

 cane-field at the ingenio "Armonia" near Bolondron, and another 

 nesting in a rotten stump in the Cienaga de Zapata about fifteen miles 

 from that town. I have also several workers taken by Prof. C. F.. 

 Baker at Cayamas and a few taken by Prof. C. H. Eigenmann in the 

 province of Havana. I find in my collection also some workers among 

 the material taken by myself several years ago at West Bay, in the 

 island of New Providence, Bahamas. All of these specimens agree 

 closely with cotypes received from Professor Forel. There is also a 

 major worker in the Gundlach collection without number or locality. 

 A deflated female taken from the colony at Bolondron measures 10 

 mm. and closely resembles the major worker. The head, however, 

 is proportionally narrower and with more nearly parallel sides; the 

 middle of the pronotum, the paraptera, wing-insertions, epinotal 

 declivity, and the petiole are yellow, the first gastric segment has a 

 yellow crescent on its anterior border and the second and third seg- 

 ments each have a large anterior yellow band, narrow in the middle 

 and much broader on the sides.
