Cevceris ariadm sp. n. 



^ . Nigra; mandibulis bast, femoribus apice, tibiis tarsisque rufo-testaceo; 

 .clypeo linea transversa, margine anteriore oculorum anguste, tegulis 

 postscutello, segmentis dorsalibiis 1-4 fascia transversa apicali flavis ; alis 

 hyalinis, apice leviter infuscatis, venis fuscis ; clypeo lamina libera, por- 

 irecta, apice late emarginata, mesopleuris hand tuberculatis ; segmento 

 mediano area basali nitida ; segmento ventrali secundo area basali elevata 

 nulla. 



Long. 10 mm. 



5 . Clypevis with the lamina porrect from the base, broader than long, 

 widely and shallowly emarginate at the apex, the clypeus below the 

 lamina concave, shining and truncate at the apex. Antennte inserted low 

 down, close to the base of the clypeus ; second joint of the flagellum about 

 half as long again as the third. Eyes almost parallel ; posterior ocelli 

 sibout one-quarter further from the eyes than from each other. Pronotum 

 not depressed in the middle, mesopleursB not tuberculate. First abdominal 

 segment much broader than long ; second ventral segment without a 

 raised area at the base ; pygidial area nearly three times as long as the 

 greatest breadth, the sides nearly parallel from the base to beyond the 

 middle, then rather sharply narrowed and very narrowly rounded at the 

 ;apex. Shining, rather sparsely and not very deeply punctured ; the 

 .enclosed space at the base of the median segment smooth and shining,
