Head generally rather short and somewhat semiglobular, flat or 

 excavated behind, as broad as or a little broader than the thorax, 

 and often broader than high. In front It is arched. and sonietimes 

 the face is somewhat prominent below the antennæ, or front and face 

 are produced to a longer or shorter snout. Yowls slightly or not 

 produced below the eyes. Antennæ placed near to each other, and 

 in or near the middle of the head, or sonietimes farther downwards 

 on the lower side; they are seven- to ten-jointed in all; the two 

 basal joints niay be of ditferent length, the following four to eight 

 form an annulated. more or less globular, compressed part, or a 

 more elongated fusiform part, the last or penultimate and last joints

 or hairy in the males and bare or nearly so in the females. Three 

 ocelli present. The oral cone varies from very short to rather long ; clypeus 

 is more or less linear, lying on the front side of the cone reaching 

 from the epistonia to the labruni; below, at Ihc end of the cone. it is 

 more or less connected with the chitinised pharynx. The proboscis is 

 of different length, the basal part of the labium is short, the labella 

 of different form, short and broad to rather long and narrow, often 

 forniing an angle with the basal part of the labium. Labrum generally 

 of the length of the basal part of labium, relatively broad, more or 

 less semitubular; hypopharynx shorter than the labrum, sometimes 

 rudimentary, generally pointed, triangular. Maxillæ wanting or present, 

 but often rudimentary. only consisting of a basal piece, rarely with a
