207. Camponotus {Mynnmnhlys) hurtoni, sp. nov. 

 Plate 6, fig. 45, 46. 



Worker maior. Length mm. 



Head, excluding mandibles, longer than broad, broadest at occiput; 

 posterior corners narrowly rounded, the border slightly convex; sides 

 in front of eyes straight. Head in profile two thirds as thick as long. 

 Clypeus a little broader than long; anterior border narrowly rounded 

 at middle; surface very convex, with a strong carina at middle. Fron- 

 tal carinae weak, extending to opposite the anterior border of eyes. 

 Eyes small, convex, situated on sides back of posterior third of head. 

 Antennae long and slender, scape extending half its length past the 

 occipital corners, funicular joints long, cylindrical. Mandibles short 

 and thick, the blade with four teeth. Pronotum twice as broad as 

 long, the surface rather flat, sides nearly straight; anterior angles 

 evenly rounded; sides and anterior border with a rounded margin. 

 No mesoepinotal suture; the mesoepinotum rounded above, then 

 declivous to base, in profile twice as high as thick. Node wedge- 

 shaped, twice as deep as thick, the anterior and posterior surfaces 

 feebly convex; narrowly rounded above. 



Sublucid, head, thorax, and abdomen very densely, transversely, 

 striolately punctate, with long silky pubescence, which is rather sparse 

 except on the front of head and the pronotum, and abundant, stiff, 

 erect pile, which is very long. Node without pubescence but bearing 

 several long hairs at the apex. Antennae pubescent, devoid of pile. 

 Femora and tibiae sparsely pilose. 



Color black; mandibles and scape rufous. Pile and pubescence 

 white. 



Described from three workers taken at Madeira-Mamore Camps 

 39 and 41. 



208. Camponotus {Myrmavihlys) novagrenadensis Mayr. 

 Two major workers were taken at Abuna. 



209. Camponotus {Myrmamblys) claviscapus Forel. 



Many major and minor workers of this species, from Natal and 

 Ceara-Mirim, agree closely with Forel's description of the types, which 

 were from Trinidad.
