which might entitle this form to a generic rank; for the 

 present, however, it may be considered as being but a 

 subgenus of Pheidole. 



39. Pheidole (Ceratopheidole) granulata n. sp. 



Soldier? Length, 5.6 mm. Head nearly twice as long 

 as broad and somewhat broadest in front, the sides gen- 

 tly arcuate, posterior angles rounded, the occiput deeply 

 and somewhat angularly emarginate; a deep median fur- 

 row extending to the frontal carinse. Frontal carinae 

 about one-third the length of the head, converging poste- 

 riorly. Frontal area distinct, elongate triangular. Cly- 

 peus transverse, extending posteriorly between the base 

 of the antennae, the posterior margin arcuate, posterior 

 margin of the lateral pieces deeply sinuate, the anterior 

 margin arcuate and angularly emarginate at the middle. 

 Eyes in front of the middle. Mandibles very robust and 

 provided with two stout teeth at the apex. Antennae 

 twelve-jointed, slender, the scape reaching to the occiput; 

 the seven basal joints of the flagellum subequal in length, 

 each about four times as long as thick, joints eight to ten 

 also subequal in length, each of them about one -third 

 longer than any of the preceding joints, the last joint 

 slightly the longest. Prothorax not quite one -half as 

 broad as the head, broadest posteriorly, prolonged into a 

 neck anteriorly, convex above and at the sides; mesono- 

 tum slightly elevated anteriorly and with a rather broad 

 and shallow, transverse, median depression; meso-meta- 

 notal constriction deep and rather broad; metanotum flat- 

 tened above, somewhat concave between the spines, the 

 basal section about twice the length of the declivity; 

 spines stout, directed back- and upward and about one- 

 fourth the length of the basal section of the segment. 

 Nodes as in Pheidole, the second node broader than long 

 and obtusely angulated.
