as the succeeding segment, and is slightly concave in front of the 

 eyes. A small frontal median process separates the inner bases 

 of the first antennae ; it is bounded on each side by a deep sinus ; 

 the lateral frontal borders are evenly rounded. First segment of 

 the peraeon nearly as long as the two following ; second to sixth 

 gradually becoming shorter, seventh segment very short. Third, 

 fourth and fifth segments more or less separated from each other 

 throughout their breadth; first and second separated at the sides; 

 the sixth and seventh have their opposed borders of the terga in 

 contact throughout their breadth. Epimera widely separated 

 from each other, all more or less acute. The lines of union 

 between the terga and epimera are very ill-defined. 



The anterior portion of the pleon exhibits slight lateral traces 

 of three segments, the first having a large epimeral process with 

 a small denticle on the base of the anterior border.
