Didictyum n. gen. (8fe, double, SIXTUOV, net) : Head transverse; three ocelli, 

 approximate and triangularly arranged ; labial palpi 3-jointed ; antennae inserted 

 in front and close together ; in the Q hardly reaching to the abdomen, 13 jointed, 

 the two basal joints stout ; joints 3. 7. suddenly narrowed and together not much 

 longer than 1. and 2.; 3. being twice as long as the others; 8. 13. twice as stout, 

 peduncled , subequal in length, very slightly narrowing toward tip ; in the QJ* as 

 long as body, 15-jointed, joint 3. twice as long as any of the others, 4. 15. sub- 

 equal in length. - Thorax as long as abdomen, slightly wider in the middle 

 than the head , scutellurn prominently raised , subovate and marginally ridged ; 

 legs with the tarsi uniformly 5-jointed ; front wings without stigma but with the 

 veins forming with the costa two closed cells ; hind wings with a stout costal vein, 

 reaching and broadening to basal third of wing where it is suddenly bent upward. 

 Abdomen narrower than thorax, with a short peduncle. The genus is 

 readily distinguished by the character of the venation and the structure of the 

 antennae, from Basalys Westw., with which it has some affinity .
