anteriorly subtruucate, distinctly angularly notched a little before 

 eyes, thence obliquely directed to apex ; eyes oblique, interiorly 

 moderately emarginate, backwardly projecting over the lateral 

 margins of the pronotum ; antennae mutilated in typical specimen ; 

 rostrum short, robust, reaching or very sliglitly passing the anterior 

 coxEB ; pronotum a little longer than head, the anterior margin 

 truncate, the posterior margin distinctly convex, the lateral 

 margins broadly augulate near the humeral angles ; mesonotum 

 somewhat concavely depressed, longer than broad, widened towards 

 middle, thence obliquely narrowed towards abdomen, the lateral

margins slightly but distinctly reflexed, the posterior margin 

 centrally inwardly emarginate; abdomen composed of six segments, 

 a little broadened from the apex of third segment, the lateral 

 margins distinctly reflexed ; anterior femora moderately slender, 

 about as long as the tibia% intermediate and posterior femora 

 subequal in length, iutermediate tibise considerably longer than 

 posterior tibia?. 



This genus is founded on an apterous specimen ; it is allied to 

 Janias, from which it differs by the structure of the head and 

 thorax ; the absence of the antenna? is much to be regretted, but 

 the insertion of the species in this enumeration is imperative and 

 may promote the collection of other specimens.
