clypeus with 5 teeth as in var. quinquedentata. Otherwise like the 

 type of the species. 



In addition, the following features should he noted. The pronotum 

 is very little wider in front than behind, two and a half times wider 

 than long, with suhangular shoulders. The mesonotum is twice as 

 wide in front as hehind; all the thoracic sutures well defined. The 

 metanotum is three times wider than long, but it is also much 

 longer and clearly defined than in the other species of the sub-genus. 

 Scale barely truncate above, the dorsal edge only feebly convex in 

 the middle. The posterior metatarsi are furnished with two rows 

 of lanceolate or subspatulate hairs, as in C. belligerum mystaceus, etc. 



Q, 106 mm. Colour of the head like that of the 2|_, but paler 

 and of a more ochreous tint, the lobe of the clypeus ferruginous. 

 Thorax, petiole, coxae, femora and tibiae reddish ochreous; a brown, 

 longitudinal band on each side of the mesonotum, tarsi and antennae 

 ferruginous. Abdomen ochreous at the base and on the ventral sur- 

 face, piceous above, with a large, sharply defined and bright ochre- 

 ous spot on each side of the 2nd, 3rd and 4th segments. 



Head quadrate, and excluding the projecting lobe of the clypeus 

 as long as wide, parallel-sided, the posterior margin strongly convex, 

 the posterior angles acute and rectangular. Teeth on the lobe of 

 the clypeus less distinct than in the %. Mandibles with 5 teeth as 

 in the %. Mesonotum very shining in front, less so behind, sparsely 

 but clearly punctured at the sides. Epinotum closely and finely 

 reticulate and dull. Posterior metatarsi as in the %. Otherwise like 

 the %.

Race subnasutus n. r. 



9J_, ca. 11 mm. (The single specimen has had the abdomen 

 distended by the action of the fluid in which it was preserved, and 

 measures actually 12*5 mm.). Ochreous, the anterior angles of the 

 head brownish, the median area of the clypeus reddish ochreous and 

 brownish at the margins; mandibles bright castaneous red, the teeth 

 black abdomen brownish yellow. The lobe of the clypeus is shorter 

 than in var. pretiosa, its sides oblique ; the median area of the cly- 

 peus is also shorter and wider, or one-third wider than long, (in- 

 cluding the lobe), whereas in pretiosa it is as wide as long. The 

 mandibles are very smooth and shining, sparsely but coarsely punct- 

 ured, 5-dentate. The scale of the petiole is a little narrower above. 

 Otherwise like pretiosa, including the posterior metatarsi.
