Hab. Morty Island.

Worker. Length 2f lines. Black and subopake; thinly sprinkled 

 with short erect white setae ; the head, thorax, legs, and nodes of the 

 abdomen roughly sculptured, the face longitudinally so, the lateral 

 posterior angles of the head with deep coarse punctures or fossulets 

 which are more or less confluent ; the sculpture of the thorax above 

 and of the nodes of the abdomen is similar; the legs are coarsely 

 roughened; the abdomen is much more finely sculptured and is 

 somewhat longitudinally aciculate, the base is coarser than the disk. 

 The anterior tibiae and tarsi and the claw-joint of the intermediate 

 and posterior pair ferruginous. The head transverse and widest 

 behind, the sides being curved, the posterior angles acute. The 

 thorax narrowed behind, transverse in front, the sides curved, ter- 

 minating posteriorly in two short, broad, acute spines. Abdomen 

 ovate. (PI. IV. fig. 7, ^ .)

Gren. Cephaloxts, Smith. 



Head subtriangular in the $ , deeply emarginate behind ; eyes round, 

 concealed beneath the grooves at the sides of the head ; ocelli three, 

 placed in a triangle on the vertex ; the antennae clavate, received into 

 longitudinal grooves at the sides of the head above the eyes, the 

 flagellum five-jointed ; the mandibles subtriangular, multidentate. 

 Thorax oblong-ovate, rounded anteriorly, posteriorly emarginate and 

 bidentate ; legs moderately long and stout, the anterior tibiae armed 

 with a stout spine at their apex, the intermediate and posterior pair 

 unarmed. Abdomen ovate, the peduncle with two nodes. 



The unique specimen from which the above ebaracters are 

 drawn is a female ; unfortunately the wings are wanting. The 

 insect somewhat resembles the Ceratohasis singularis, which I 

 characterized in the first volume of the ' Journal of Entomology;' 

 but from that remarkable genus it is separated by its six-jointed 

 antennse, besides other characters ; it is one of the most re- 

 markable insects with which I am acquainted, and it is the only
