This insect is apparently nearest E. walkeri (Kirby), the only 

 previously known Malayan member of the present genus. From 

 the unsatisfactory description of the unique female type of that 

 insect, the single male before us is separated by the immaculate 

 vertex and unarmed ventral femoral margins. Adequate diagnosis 

 of walkeri will probably reveal other distinctive features. 



Compared with the other species of Eumecopoda, the present 

 insect differs greatly in the very much shorter limbs and organs of 

 flight, the unarmed ventral femoral margins and caudal femora 

 which are as strongly carinate as in E. cyrtoscelis (Karsch), but 

 bear fewer and smaller tuberculations. From the males before us, 

 further difference is shown by the strong medio-dorsal projections 

 of the abdominal tergites and the much shorter cerci and subgenital 

 plate, the latter bearing at its apices minute but distinct styles. 47 



In general form the present insect shows closer resemblance to 

 species of the genus Characta, from which genus it may be instantly 

 separated by the broad, transversely carinate and undivided 

 vertex. 



Type: cf ; Butuan, Mindanao, Philippine Islands. (From C. F. 

 Baker.) [Hebard Collection, Type no. 853.] 



Size comparatively small, form very short for the genus. Vertex 

 truncate distad, nearly transverse, bluntly but decidedly trans- 

 .versely carinate, due to a weak concavity of the dorsal surface 

 toward this carina, which itself, unliked in the other species, pro- 

 jects slightly beyond the plane of the face. Face and genae mod- 

 erately, occiput and pronotum very thickly impresso-punctulate. 

 Pronotum shorter than in other species, with incisions of the 

 strongly carinate lateral margins, at transverse sulci, much smaller 



47 Smaller but otherwise as in Mecopoda elongata (Linnaeus).
