area; dorsal face slightly concave; inner face concave with three stout blunt teeth 

 on dorsal edge and one similar tooth on ventral edge, these teeth are all beyond 

 the outer third of the mandible; molar area (Fig. d, 1) strongly produced, obliquely 

 quadrate and concave, with outer ventral edge drawn out into a stout tooth, 

 concave surface transversely carinate. Gula (e, 11) trapeziform; submentum 

 (e, 3) broad, hexagonal; men turn (e, 2) trapeziform with narrower edge directed 

 posteriorly, as long as submentum but narrower and bearing a pair of bristles 

 at base; labium (e, 1) roughly pentagonal smaller than mentum; ligula pronounced 

 and armed with a pair of short spines; labial stipes (e, 10) moderately large; labial 

 palpi (e, 9) two jointed, joint one short and broader than long, joint two equal 

 in length to one but only as wide as long. Maxilla? large; articulating membrane 

 (e, 4) between submentum and cardo slightly chitiuized, quite large; cardo (e, 5), 

 large, triangular; maxillary stipes (e, 6) large; maxillary palpi (e, 8) three jointed; 

 lacinea (e, 7) broad and armed with two rows of broad short spines. Hypopharyn- 

 gial chitinization (Fig. b) tricuspid, with surface concave, highly chitinized. Anten- 

 nae (Fig. c) situated at base of mandibles, three jointed, basal membrane large 

 protuberant slightly chitinized, joint one nearly as broad as long slightly widened 

 distally, joint two clavate, twice as long as wide, surmounted with a cushion like 

 membranous cap on which is situated a small disc like antennal appendage and 

 the small third joint; third joint less than one-fifth length of second joint, cylin- 

 drical, one-third as wide as long, bears two small hairs; antennae slightly retractile. 

 First thoracic segment as long as broad, anterior margin finely striate; second 

 about one-half as long as first and third a little longer than second. Legs (Fig. i) 

 moderately long, coxa as long as femora and trochanter taken together, scoop 

 shaped with concave membranous surface to receive femora when in repose, edges 

 of this surface beset with hairs; trochanter large, triangular and serving as a support 

 for femora, over the inner two-thirds of which it is prolonged; femora stout and 

 short; tibia equal to femora in length but more slender; tarsus unguiform, in 

 length almost equal to tibia; femora and tibia with stout spines on inner edge. 

 Mesothoracic spiracle oval and twice as long as the abdominal spiracles. Ten 

 abdominal segments, one to eight .about equal in diameter and length, posterior 

 borders strongly deflexed but not striate, dorsal surface sparsely and finely punctate 

 and slightly transverse-rugose, rugosity becoming more pronounced and puncta- 

 tion more dense and coarse caudad; ninth abdominal segment (Fig. j) obliquely 

 truncate, truncate surface strongly concave with acute margins; tenth abdominal 

 segment (Fig. h) in small semi-cifcular orifice on basal quarter of venter of ninth 

 abdominal segment and bearing two mammiform papillae. Spiracular area of 

 segments one to eight (Fig. h) oblong, with small almost circular spiracles on 

 anterior dorsal margin. Length 27 mm. 



The nidus in which I found these larvse was composed of deep 

 leaf mould and decayed wood. They seemed very sensitive to 

 light and very rapidly burrowed away when unearthed. Several 

 were collected and placed in rearing cages. Three days later 

 (May 5) three of the larvae had pupated. The last larval exuvia 

 were preserved for future identification of this species of larva. •
