THE MYKIAPOHA in the Al'STnAMAN MUSEUM liRcU.EMANN. Ill 



Space between the eyes once and a lialf the diameter of an 

 eye; ocelli 50, in eight rows (9+9+8+7+6+5+4+2). 

 Antennffi rather long", reacliiny tlie postei'ior mai'gin of the fii'st 

 segment, slightly thickened distally ; the three proximal joints 

 naked, the following gi-adually more pilose. Last joint tipped 

 with four sensory cones remote from one another. Micrometrical 

 measurements of joints : 1st joint 0.946 m/m; 2nd, 1.849 m/m ; 

 3i-d, 1.376 m/m ; 4th, 1,333 m/m ; 5th, 1.247 m/m ; 6th, 

 1.075 m/m; 7th and 8th, 0.172 m/m ; total length 7.998 m/m. 

 Diameter of 2nd joint 0.860 m/m ; of 6th 0.989 m/m. 



Anterior part of prozonite with concentric sulci ; on the 

 posterior part, the oblique strife are very fine and their lower 

 margin is raised into a tiny ridge. The metazonites are said 

 to bear eight strong teeth, which is correct for the posterior 

 half of the body ; but, on the anterior half, the main ridges are 

 less regular and may number ten on the first segments, and, 

 further back, nine (in this case, the odd ridge stands on the 

 median dorsal line). Between the main ridges, minor irregular 

 ridges are to be seen, very conspicuous on segments two to 

 five and gradually decreasing backwards. Sutural sulcus 

 obsolete dorsally, distinct below the pores though not strongly 

 marked. The space immediately in front of the suture, in the 

 dorsal region, is coarsely punctured ; it is widely depressed so 

 as to give rise, on the prozonite, to an abrupt ridge ; this was 

 mistaken by Daday for the suture and led him to erroneously 

 state that the pores open in the metazonite. Pores beginning 

 on the sixth segment, standing high in the sides, very small, 

 pierced in the middle of a somewhat raised spot, in front of 

 the suture. 



The produced marginal angle of the last segment conceals 

 the upper angles of the valves, but does not exceed the level of 

 their outer margins ; it is somewhat compressed laterally, 

 slightly raised and separated from the rest of the segment by a 

 deep wrinkle. Anal sternite very wide and very short, with 

 almost straight posterior margin. 



On all legs, the coxfe are slightl}- produced and rounded, the 

 following two joints are compressed latei-ally and ridged below. 

 Tarsi padded. Joints, except the last, with but one distal 

 bristle below.
