EIPHOSOMA. nov. gen. (Fig. 5.) 

 Head transverse, wider than the thorax ; face flat ; clypeus small, 

 slightly prominent, rounded in front; mandibles, moderate, broad; eyes 

 large, ovate, entire; ocelli placed in a triangle on the vertex; front ex- 

 cavated behind the antennae ; palpi long 

 \and slender. Antennae moderate, rather 

 slender, longer in the % ; basal joint short, 

 globose, obliquely truncate exteriorly, re- 

 ceiving the 2nd and 3rd joints, the 3rd 

 minute; 4th joint long, the 5th and 6th 

 subequal, each shorter than the 4th, re- 

 maining joints gradually shorter, the terminal joint as long as the two 

 preceding joints, acuminate at tip. Thorax gibbous, short and nar- 

 row; mesothorax with the middle lobe prominent; scutellum suborbic- 

 ular, more or less convex ; metathorax moderate, its face oblique, with 

 a deep longitudinal central groove. Wings moderate ; stigma slender ; 

 areolet minute, oblique, or wanting. Legs slender, the two anterior 

 pairs short; posterior pair very long, their femora slightly thickened, 

 with a short, stout, acute tooth beneath near the tip; all the coxte short 

 and robust, the trochanters elongate, the four anterior femora long, 

 slender and slightly recurved ; tibiae slender, gradually thickened to- 

 wards the tips, the spurs long, those at the tips of the four anterior 

 tibiae unequal, those <>u the posterior pair equal in length; tarsi slender, 

 the claws very small, apparently simple, pulvilli large. Abdomen very 

 long, slender, shaped somewhat like an inverted cimeter ; two basal seg- 

 ments long and linear, second rather the longest; remaining segments 

 broad and much compressed; apex obtuse in the % , truncate in the 9 , 

 the ovipositor sometimes short and sometimes moderately long, the 

 sheaths pubescent, thickened at tips, sometimes apparently proceeding 

 from the superior portion of the ventral valve, as represented in the 

 figure. 



This genus may be known by the long, slender, compressed abdomen, 

 shaped somewhat like an inverted cimeter, and the long posterior 

 legs, with their femora toothed beneath near the tips. It seeu>s to 

 be closely allied to Oremastus and also to Angitia Holmgren, but differs 

 from both genera principally by the toothed posterior femora. 



Eiphosoma atrovittata, n. sp. 



Yellow; posterior legs and abdomen dull honey-yellow; three lines on meso- 

 thorax, three on metathorax and an oblique one on pleura, black ; wings hya- 

 line, tips fuscous, areolet minute, oblique and petiolated. 



Female. — Head yellow, tips of mandibles and a spot on vertex cover-
