FUSTIGERODES AURICULATUS, Wasm, 



Wien. Ent. Zeits., xvii., 1898, p. 98. 



This species is very closely allied to F. majusculiis, Per.; the 

 body is not so broad, and is more parallel, the colour is a little 

 lighter, the head and the prothorax are more elongate, and the 

 punctuation much less strong ; the last joint of the antennae is 

 longer, thinner, and a little curvate ; bvit the main difference is found 

 in the abdominal processes ; in F. majusculus these processes are 

 flattened on the upper part and strongly carinate in each side ; in 

 F. atiricidatus they are much more prominent, the upper part is 

 rounded, convex, punctate and piliferous without any trace of carinule; 

 the triangular tooth of the intermediate femora is a trifle smaller, and 

 the tubercle placed before the apex inside the tibiae of the same legs 

 is not so strong, the size is also a little smaller. Length 2-10 mm. 

 In his description the Rev. S. Wasmann gives 2-3 mm. as the size ; 

 very likely his typical specimen is a trifle larger than mine. 



It differs from F. capensis, P6r., by the more elongated body, the 

 colour much lighter, the head shorter and more parallel, the pro- 

 thorax more cordate and not so much rounded, the more slender 

 and much more regularly conical terminal joint of the antennae, the 

 more elongate elytra, and the form of the processes of the abdomen 

 which are similar in both F. majusculus and F. capcnsis ; the basal 

 depression of the abdomen is also much larger in F. auriculatus than 

 in F. capensis. 



This interesting species described {loc. cit.) by the Rev. S. 

 Wasmann has been discovered by Dr. Brauns in Port Elizabetli 

 amongst the ant Bhoplaomyrmex transversinodis, Mayr. in litt. I 

 have not seen type, but Dr. Brauns has kindly given me a male 

 specimen which I have no doubt belongs to the same species as the 

 one described by the Rev. S. Wasmann.
