and finely punctate as in the worker; epinotum, petiole, and gaster 

 very finely punctate-shagreened and shining. 



Hairs pale, erect, very sparse on the head and thorax, more abundant 

 on the gaster; pubescence yellowish, on the gaster much as in the 

 worker, long and dense and nearly concealing the surface. 



Black; mandibles, funiculi, legs, petiole, and gaster reddish brown; 

 wings dull brownish hyaline, with brown veins and pterostigma. 



Described from numerous specimens taken by Mr. A. E. Wight at 

 Troy (type locality), Mandeville, and Balaclava. Those from Mande- 

 ville were attending merabracid nymphs. In my 1911 list of Jamaican 

 ants I referred this form to the typical capperi, but it undoubtedly 

 represents a distinct variety or, perhaps, even a subspecies. 



39. Camponotus (Myrmobrachys) capperi subsp. corticalis Forel. 



In this subspecies (Fig. 3 6), of which I have examined three cotypes 

 taken by Forel at Kingston, the thorax is like that of the var. formo- 

 sulus, except that the mesoepinotal suture is more deeply impressed. 

 The color is different, the head, thorax, and gaster being black, the 

 antennae, legs, and petiole red, the antennal scapes and tibiae have 

 numerous suberect hairs and the pubescence on the gaster is much 

 shorter and sparser so that the shining surface is clearly visible. 



40. Camponotus (Myrmobrachys) capperi subsp. subdepilis Wheeler. 

 ^. — Port Antonio, Troy, and Balaclava {A. E. Wight). 



This form (Fig. 3 e), described as a variety of corticalis, evidently 

 deserves to rank as a subspecies. The head of* the major worker is 

 longer, more elliptical and with more convex occiput; the epinotum 

 is shaped like that of the subsp. corticalis, but the mesoepinotal 

 suture is less impressed. The erect hairs on the body are much less 

 numerous and lacking on the scapes and tibiae. The color and sculp- 

 ture are similar, but the gaster is somewhat more shining and the 

 petiole is darker. 



*41. Camponotus {Myrmobrachys) capperi subsp. unctidus, subsp. nov. 



Worker. (Fig. 3 c). Length 4.5-6 mm. 



Head of the maxima much as in the typical capperi, subtrapezoidal, 

 with the sides and posterior margin feebly convex. Thorax differing 

 from that of all the preceding forms of capperi in being shorter, more 

 convex anteriorly, with the epinotum lower and much more com-
