 falcatae, acutissiniae, sub- 

 aequales, dente medio 

 valido, duplici, acumine,

First joint <^f antennae long, 

 slender and flat, iinier margin 

 with seven very distinct

 of equal length, each being about 

 three times short (^r than the first. 

 Second in the middle of its outer 

 margin with an elevation bearing 

 a sense-organ in the shape of 

 a chitinous ringlet witli hairs in 

 the centre. 



Antennae scapo longissimo, 

 serrato, masticatoriae. 



Mandibles shaped as a sharp, 

 bent, and strong sickle with 

 secondary teeth on its concave 

 surface, the first largest, lancet 

 like ; the middle tooth tetra- 

 gonal with a concave free surface 

 and sharp prominent edges ; 

 hind tooth in the shape of a small 

 tubercle at the base of the middle 

 tooth. 

 Stipite.s maxillares gracillimi, longis- 

 simi, palpos labiales excedentes. Palpi 

 maxillares graciles ; stipes gracihs, re- 

 curvus, articulo primo triplo longior. 

 Mentum (Text-lig. 4, m) Mentum (Text-fig. 3, m) bell-

 dine, angulis dentiformibus, teeth. Side margins smooth, 

 lateribus serrulatis. slightly S-shaped. Stipes com- 

 Stipes palporum labialium pared with the mentum much 

 elongato-quadratus, basin more developed than in the 



mature larva of H. cara- 

 bo ides, and in the form of an 

 elongate rectangle which in its 

 fore part is wider than behind. 

 The base of the ligula occupies 

 almost half of the width of the 

 anterior margin of the mentum 

 (in the mature larva of H. c a r a - 

 b o i d e s only one-fourth). Tip of 

 the ligula is somewhat bilobate (Ig) .
