however relatively longer. Pseudostigmatic organs long, not davate 

 neither fusiform , with only three or four spines on their setiform 

 distal end. Lamellae running nearly parallel forward, somewhat 

 undulated. Two other chitinous bars stand between the lamellae, 

 running from the abdomen straight forward. These bear the inter- 

 lamellar hairs , which are turned backward. Two little lamellar 

 hairs; moreover some very low chitinous ridges mark the céphalo- 

 thorax. The abdomen is oval, bears in its foremost part three very 

 low chitinous ridges , running from its margin backward. Four 

 longitudinal rows of nearly inconspicuous fine hairs; four hairs on 

 hind-margin. The legs (I have not delineated the hairs on the 

 legs) remember those of Eremaeus longilaniellatus (Michael), 'peo- 

 Unatus (Michael), lanceolatus (Michael), etc., having pyriform 

 femora and tibiae, and nearly fusiform tarsi.

This species (Fig. 6) is closely allied to Eremaeus tngon us 

 (Michael) and Eremaeus suhtrlgonus Oudms. Like these two it has 

 a truncated rostrum with three points.
