ILdictiis zonatulus, sp, n. 



Black, tlie tarsi testaceous ; the abdominal segments banded 

 at the ajjices with olive-testacoous ; wings cle-ir hyaline, the 

 stigma dark, the nervures pale testaceous; the area on 

 the median segment stoutly, irregularly, longitudinally 

 striated. ,^ .

In Bingham's arrangement (/. c. p. 421) this species woul I

Antenna3 stout, rather thickly covered with a short black 

 stiff pile; the scape with longish wiiite pubescence. Heal 

 closely and distinctly punctured; the clypeus smooth and 

 sparsely punctured above ; thickly covered with pale hair, 

 which is darker-coloured on the vertex than on the face or 

 clypeus ; the front has a narrow but distinct keel on tho 

 middle. Mandibles black, testaceous near the middle, the 

 apex piceous. Thorax thickly covered with pale fuscou-i 

 hair ; the mesonotum and scutellum closely minutely punc- 

 tured. The area on the median segment is large and is 

 distinctly bordered behind ; there is a distinct longitudinal 

 keel in the centre, some irregular ones on either side of it, and 

 three regular ones on tlie edges; the apical slope of the 

 segment is furrowed distinctly in the centre. Propleurai
