Corethrte valde affinis. Os longius. Os et rostrum conjunctim capite 

 longiora. Rostrum proboscide vix brevius. Palpi 4-articulati, pro- 

 boscide duplo longiores ; articulus primus brevis ; quartus tertio 

 paullo lougior. Antennae 16 -articulates ; articuli primus et se- 

 cundus breves, moniliformes ; tertius sequentibus longior et crassior ; 

 ultimus linearis. Ungues graciles, acuti, dente gracili acuto basali. 

 Rostrum almost as long as the proboscis. Mouth along with the 

 rostrum longer than the rest of the head. Palpi four-jointed, twice as 

 long as the proboscis ; first joint short ; fourth a little longer than the 

 third. Antenna? sixteen-jointed ; first and second joints short, monili- 

 form ; third longer and thicker than those which follow ; the single 

 joints incrassated at the base, verticillate ; they increase in length to 

 the last, which is linear. Wings distinctly but finely veined ; two fur- 

 cated veins, with their fork nearly equidistant from the base of the 

 wing, and therefore that of the anterior further from the margin, as 

 long as one-third of the wing ; the branches more than twice as long 

 as the petiole ; brachial areolets coterminous ; the pobrachial irregular 

 at the apex ; posterior vein (subanal) inflected at an angle a little before 

 the margin, and running along the margin towards the apex of tin: 

 wing ; this vein, as usual, doubled by a spurious one ; one longitudinal 

 vein behind it. Ungues slender, acute, one-third of the length of the 

 fifth tarsal joint ; a slender acute tooth at the base, half as long as the 

 ungues. The wings are nearly as in Corethra, only the transverse vein- 

 lets rather more distant from the margin. The figure, development of 

 the mesosternum, and antennae much alike ; the mouth longer and more 

 deflected.
