ia. Head subtruncate at apex, transverse slit very broad, cutting a deep

 p. 162 (igog). 



Characters. — Male. — Plead transverae, closely and coarsely punctate, eyes many facetted. 

 Mandibles very short, pubescent: maxillae cylindrical two-jointed, the second longer. Antennae seven- 

 jointed, the prolongations of the last five joints flattened, foliaceous, of graduated length, the apical 

 being shortest. Pronotum obovate, disk-like, not connected externally with the presternum, projecting 

 about equally into emarginations of the head and mesonotum. Mesonotum very deeply emarginate for 

 reception of pronotum, but laterally reaching head; basal margin straight. Elytra rather short. Meta- 

 thorax with praescutum oblong, slightly widest at base, truncate at apex; scuti narrowly elongate, not 

 longer than prasscutum ; scutellum very short, base convex, apex truncate, sides concave; postlumbium 

 transverse, very short; postscutellum very long. Wings as in Neocholax, but lacking both cubitus and 

 third anal. Presternum a mere rounded, oblong disk; propleurae lacking. Anterior coxa? and trochanters 

 contiguous; middle coxae separated.

Characters. — Male. — Head short and transverse. Mandibles very short and stout, abruptly 

 acute at apex, not reaching each other; maxillae with first joint extremely slender and second more than 

 twice as long and largest beyond middle, apically acute. Antennae seven-jointed, the third to sixth joints 

 laterally produced, but the branches not compressed at base, seventh joint thin and lamellate. Prothorax 

 causing deep emargination of head, not visible at sides. Mesothorax transverse. Metathorax with 

 praescutum elongate, subtriangular, broadest in front, narrowly rounded behind; scuti oblique, narrowly 

 separated; scutellum transverse, with all sides sinuate; postlumbium transverse, subquadrate, shorter 

 than scutellum, not differently colored; postscutellum a little longer than all the preceding parts. Wings 

 with seven primary veins from base, radius meeting costal margin beyond middle, medius unbroken, an
