MANX: AXTS OF THE HHITISH SOLOMON ISLANDS. 375 



San Cristoval: Wai-ai (Type-locality). Santa Cruz: Graciosa 

 Bay. Santa Anna. Three Sisters: Malapaina. Ugi: Pawa. Mal- 

 aita: Auki. 



Described from numerous soldiers and workers taken from colonies 

 nesting in hollow vines at Wai-ai and from workers and soldiers found 

 running on leaves. There is considerable variation in the amount of 

 infuscation on the head and the Malapaina and Auki specimens are 

 pale in color, perhaps being varietally different, but more probably 

 not fully colored. 



Campoiwtus loa is near C. conithorax Emery, from the New Hebrides, 

 but differs in size, color, and in the more convex base of epinotum. 

 Camponotua conica ]\Iayr. from Tonga has the epinotum similarly 

 shaped in the worker but the petiolar node is armed with two spines. 

 Type.— M. C. Z. 9,185. 



107a. C.\iiP0N0Tus (CoLOBOPSis) LOA Mann, var. belli, var. nov. 



Several workers and soldiers found running about on the trunks of a recently 

 feUed tree agree in habits and sculpture with the type form, but in the soldier 

 the front of head, the cheeks, thorax, epinotum, and petiole, and the middle 

 and hind femora are dark brown, almost black. The anterior femora are 

 mostly black, but blotched with yellowish brown. The light-colored bands 

 on the othen\-ise black gaster are much narrower. The worker is black, 

 except on the extreme anterior border of clj-peus, the mandibles, antennae, 

 tibiae, and tarsi, which are pale brown.

 convex in profile, margined laterally; humeral spines broadened basaU}' -ndth 

 the inner corners angulate, apical three fourths slender, compressed and acute 

 at tips; extending fon\-ard and outward and bent downward. Mesonotmn
