and labial palp contains one large sensillum and one to three smaller 

 sensilla; the labral sclerite is absent; the mandibles are relatively small 

 and consist of a large base and a small slender blade; this blade may 

 be toothless or may have small blunt teeth on its dorsal and ventral 

 surfaces; in some genera a lightly sclerotized band is present connect- 

 ing the posterior pleurostomal processes across the dorsal surface of 

 the food meatus; the antenna is disc-shaped; the closing apparatus 

 of the spiracle adjoins the atrium except in Glypta; the skin has small 

 setae and small conical projections but no spines.

Glypta sp. was examined. 



With its rounded labial sclerite which is incomplete ventrally and 

 its lightly sclerotized prelabial sclerite, Glypta resembles the Lis- 

 sonotini. The long hypostoma resembles that of the Banchini. As in 

 some Banchini and some Lissonotini a sclerotized bar connecting the 

 posterior pleurostomal processes is present. The mandibles are 

 distinctive with their slender toothless blades and, unlike other 

 Lissonotinae, the closing apparatus of the spiracle does not adjoin 

 the atrium. 



Glypta jumiferanae (Viereck) is figured by Brown (1947), G. 

 haesitator Gravenhorst by Cameron (1938), and G. parvicaudata 

 Bridgman by Beu-ne (1941).

Members of this tribe are parasites of caterpillars in burrows and 

 leaf rolls.
