front part of the thorax being prominently produced over the neck, and 

 in the posterior cross vein at the base of the discal cell and the 6th vein 

 lying very close to the 5th for about one-third of its length. The radical 

 difference is the presence of the submarginal cell ; the 2nd vein is short, 

 turning into the costa at an angle of 45° just beyond tip of 1st vein : 

 3rd vein bisinuate, more or less parallel with upper branch of 4th 

 vein. AuxiHary vein very close to 1st, ending in costa opposite origin 

 of praefurca ; subcostal cross vein present, a little before tip of auxi- 

 liary vein. The eyes are distinctly or very widely separated on the 

 Irons, contiguous or distinctly separated below. 



Type species : C. latifrons, sp. nov. 



This genus is practically a Limnohiorhynchus with the submarginal 

 cell present, or in other words it possesses the typical venation of the sub- 

 family with the peculiar characteristics of Limnohiorhynchus, that is, 

 the enormously prolonged rostrum about as long as the whole body, 

 the conically produced thorax over the neck and the long verticils on 

 the last two antennal joints only. 



There are two species, distinguished by a great difference in the width 

 of the frons, though they are obviously congeneric. 



Eyes separated above by a very broad frons, about one- 

 third the width of the head, with parallel sides ; 

 contiguous on under side of head 



Eyes separated above by a comparatively narrow frons, 

 about one-eighth the width of the head with very 

 convex sides ; on under side separated by one-fifth 

 the width of the head .....
