Black, shining ; antennae nearly as long as the head and thorax, thin, 

 tapering very perceptibly towards the apex, the third and fourth joints 

 nearly equal ; on the under side they are testaceous. Head a little 

 narrower than the thorax, slightly pubescent, sutures distinct, antennal 

 fovese large and moderately deep ; clypeus incised at apex ; the 

 clypeus (except at base) and labrum, with palpi, pale white, except at 

 apices of the joints, which are fuscous ; mandibles dark brown. 

 Thorax and sides of the breast smooth, shining ; tegulse, and a line on 

 the pronotum, testaceous. Abdomen broad, a little flattish, expanded 

 at the sides, sharply rounded at apex ; cerci longish, testaceous ; saw 

 short, sheath hairy. Legs testaceous-yellow; coxae and trochanters 

 pale white ; the tibia3 pale. Wings hyaline, with a brownish tinge ; 

 nervures black ; costa and stigma sordid testaceous. The second 

 cubital cellule is more than double the length of the third, and has a 

 horny point at the anterior end ; third small, dilated at the apex ; the 

 second recurrent nervure is received a little in front of the third 

 cubital. 



The (J has the antennae brownish, with a black line above ; the pro- 

 notum is entirely black ; the back of the abdomen is black, except at 

 the apex, which is widely emarginated ; the posterior tarsi are fuscous. 



Length 2J 2f lines. 



Ab. a. Wings with one radial cellule. 



From D. stilata, the present species may be known 

 by having only a thin testaceous line on the pronotum, 

 the pleurae quite black, the abdomen shorter, wider, 

 and more rounded at the apex, and the legs paler and 

 marked with black at the base. The coloration of the
