J. Tlip linrjic is scarcely as imicli raised above tiie |)lane ol" the c.las})er as 

 in gannascus ; the snbmesial ridge is especially low. The rod-like carina of the 

 l)enis-sheath is ajHcally ratlier prominent ; there is apparently no internal cariniforiu 

 thickening of the penis-sheath. The tenth sternite is shaped as in (/(/rina, the 

 tergite as slender as in palmeri.

6 ?. The cS is much more strongly marked than the ?, in which the undulated 

 and dental ed lines of the forewing are only vestigial or even absent. The most 

 distal Hue is proximally convex between the veins down to R', while from R' to 

 M- the internervular portions are proximally concave ; the same is the case in the 

 two preceding species, where the lines are, however, very faint as a rule. Individually 

 variable. 



c^. Sexual armature similar to tha,t oi gannascus ; penis-sheath simply truncate 

 at the end, not more strongly chitinised dorsally than laterally and ventrally, no 

 kind of dorsal process or carina. Tenth sternite broader basally thau in yannascus, 

 more evenly rounded apically, with just a trace of a mesial sinus, more extended 

 spiny than iu the other species of Amj>/i/j>ft'nts. 



?. Vaginal plate (PI. XV. f. lO) rather more strongly cliitiiiisod tlian in 

 yaiiiinsfus, distally rounded.

 Head small, frons vertical, a mesial crest, developing to a transverse crest between 

 antennae. Eyelashes present. Palpus small, truncate, second segment broadest 

 at end, anterior angle ])rojectiug forward (side-view), terminal surface at an obtui-c 

 angle with the frons. Antenna as long as (cJ), or shorter than (?), R^ of forewing ; 

 end-segment short, with a brush of long scales (nearly as in Amplyp(frus); segments 

 of ? with the basal ciliae very feebly prolonged. Abdomen without spinules on the 

 sternites, but the under scales of the tergites nearly all spiniform, no broad scales on
