eacli other, 5 apical ami dimitliiite, sutural ceases just beyond 

 tlie niiiMle ami for two thirds of its l('ii;^th turns slightly 

 away from the suture ; the jjropygidium has scattered punc- 

 tures, with the surface between them microscopically strij^ous 

 and finely punctulate; the py<i;idium is very densely and simi- 

 larly sculptured, but except at the base it is free of the hiri^iir 

 })uncturi\s, the dense strij^osity gives an appearance of opai:ily ; 

 the prosternuu), the anterior lobe is strongly j)unctate, witli a 

 carinitorm lateral stria, and the apex is obtusely produced 

 like the mesosternum of a Cctonia (Hg. 3); the mesosterimm 

 is widely arched ajiteriorly, with a complete marginal stria; 

 the anterior tibiie are 5-de)itate, ajjical tooth bifid. 



Hister ferrcemotux. Lew. 



Ulster philippinensis^ Mars., superficially is very similar to 

 this species, but the sculpture of the pygidium and the 

 curious |)rolongation of the prosternal lobe will at once distin- 

 guish it. //. philippinensis usually has the fourth dorsal 

 stria complete, but ^larseul's original specimen had but three, 

 and the first abdominal segment has a bowed lateral stria; in 

 JL lerrcemotits it is oblique. Jt also resembles //. myrmidon, 

 Mars.
