angles of the pronotum, the more distinct Conozoa-Yike tegminal bars 

 and the color of the caudal femora. 



The great elevation of the prozonal section of the median carina of 

 the pronotum immediately separates it from most of the species. No 

 close relationship exists to Conozoa wallula or any of the recently 

 described species of that genus, the whole build being different from 

 that seen in most of the forms of that genus, although C. acuminata 

 approaches it very closely in this respect. 



Size small; form compressed, slender and elongate; surface finely 

 punctate. Head with the occiput considerably elevated, domed; 

 vertex but slightly lower than the summit of the eyes; fastigium 

 strongly declivent, rather broad in both sexes, greatest width very 

 slightly more than the length, lateral margins distinct and very dis- 

 tinctly converging cephalad, passing into the carinse of the frontal 

 costa without interruption, median carina of the fastigium precurrent, 

 less distinct than the lateral margins of the same; frontal costa rather 

 regularly but not strongly expanding ventrad, the margins sub- 

 parallel for a short distance around the median ocellus, median sections 

 distinct sulcate, less so dorsad, the marginal carinse reaching the 

 clypeal margin ; antennse slightly less 

 than twice the length of the head 

 and pronotum, slightly depressed; 

 eye subovoid, moderately promi- 

 nent particularly in the male, slightly 

 greater than (male) or equal to 

 (female) the length of the infra- 

 ocular sulcus. Pronotum rather 

 narrow; cephalic margin of the dor- 

 sum very obtuse-angulate, caudal 



margin very slightly obtuse-angulate; median carinae cristate on the 

 prozona and strongly divided into two lobes by the first sulcus, the 

 incision being V-shaped and quite broad in the male and very narrow 

 in the female, the cephalic lobe is subtrigonal in the male and lower 

 and more longitudinally rounded in the female, second lobe equal to 

 the first lobe in height and rounded dorsad in both sexes; carina of the 

 metazona subcristate in both sexes; prozona about two-thirds the 

 length of the metazona; lateral angles of the disk very distinct, and 

 slightly carinate on the cephalic section of the metazona; lateral lobes 

 slightly deeper than long, the ventro-caudal angle rounded w'lih. a very 

 slight indication of a ventral blunt protuberance.
