 moderately deeply emarginate ; basal joint of labial palpi quite 

 cylindrical, longer than the second which is sub-quadrate, wider 

 than the first and truncate at tip, apical joint half the width of the 

 second, nearly as long, and set in the centre of the apex of 

 the former ; maxillae strong, deeply sinuate and emarginate inwardly, 

 apical lobe oblong, longer than broad, internal lobe nearly as long as 

 the whole inner part of the maxillae ; apical joint of the maxillary 

 palpi fusiform outwardly, acuminate at tip, very deeply grooved 

 inwardly for nearly all the length, and as long as the three basal 

 ones put together ; basal joint of antennae moderately slender^ 

 slightly increased at tip, second as broad as the apex of the pre-
