above and beneath, and is about twice longer than the breadth of 

 the head. Prothorax short, with a middle keel, angular and much 

 advanced in front, and equally excavated on the hind border. 

 Wings vitreous; veins green. Fore wings covered with minute 

 tubercles ; apical third part with very numerous and mostly irre- 

 gular veinlets. Hind wings with very few veinlets. Length of the 

 body 3^ lines ; of the wings 7 lines. 



This species, as regards the veins of the fore wings, differs 

 much from most of the other species of Dictyophora^ and approaches 

 the genus Plegmatoptera.

DiCTYOPHORA MELANOGONA. 



Mas. Testacea, viridi varia ; vertex carinatus, nigro marginatus ; 

 comu lineare, nigro lineatum, apice subdilatatum, capitis 

 latitudine non duplo tongius ; frons bicarinata, rufo lineata ; 

 fades lanceolafa, unicarinata ; prothorax brevissimus, sub- 

 carinatus, margine postico lineisque (juatuor lateralibus nigris ; 

 mesothorax triearinatus ; alee vitrea, venis nigris hasi testa- 

 ceis ; anticce apice stigmateque venulas quinque includente 

 lurido-fuscis. 



Male. Testaceous, mostly green beneath and partly so above. 

 Vertex much longer than broad, with one keel ; borders black and 

 elevated. Protuberance of the head quadrilateral, rather shorter 

 than twice the breadth of the head, linear, very slightly dilated at 

 the tip ; angles black. Front long, widening towards the face, with 

 two red keels and with red borders. Face lanceolate, with one keel. 

 Prothorax above curved, very short, with a slight keel, black along 

 the hind border, and with two black lines along each side. Meso-

 the base. Fore wings lurid-brown at the tips ; stigma of the same 

 hue, containing five veinlets. Length of the body 5^ lines ; of the

 tuberance of the head is shorter, the prothorax is less arched, and 

 the legs are stouter.
