setae on each side, and each scutellum with 10 short setae. Abdomi- 

 nal segments 7-10 similar in breadth; segments 9 and 10 each with 

 two transverse rows of closely placed setae, but dorsa not divided. 



Raster with teges of 36 hamate setae scattered irregularly on the 

 venter of 10th abdominal segment, three long and slender setae on 

 each side. Lower anal lobe divided into two adjacent sublobes.

Description based on the following material: 



Material examined: 30 third-stage larvae reared in soil from 

 type locality July 31 to Sept. 2, 1949, by O. L. Cartwright (USNM); 

 10 third-stage larvae reared in sand from type locaHty Nov. 18, 1952, 

 by O. L. Cartwright (USNM). 



Description: Maximum width of head capsule of third-stage 

 larva 1.02-1.09 mm. Cranium light yellow, surface smooth. Three 

 dorsoepicranial setae on each side. Frontal sutures distinct. Clypeus 

 not marked into preclypeus and postclypeus. 



Epipharynx with protophoba bistichous on left and monostichous 

 on right; protophoba with 17-19 microsensillae ; laeophoba poly- 

 stichous; dexiophoba and mesophoba monostichous. Crepide small 

 and subcircular; epitorma asymmetrical, bilobed apically and bent 

 towards laeophoba. 



Mandibles yellowish brown with scissorial and molar area reddish 

 brown. Each mandible dorsally with two setae, vcntrally with two 

 or three setae. Brustia well developed on left mandible but weak 

 and indistinct on right mandible. 



Maxillary stridulatory area with a row of 8-10 blunt teeth; small 

 toothlike markmgs behind the plectrum and on cardo. Galea ven- 

 trally with a long seta and a row of four of five short setae. Palpifer 

 distinct. 



Abdominal segments 1-6 each with three dorsal annulets; each 

 annulet with a transverse row of setae, except the last annulet of 

 segment 6. Dorsal annulets of segments 1-5 with setation as follows: 

 each prescutum with six short setae, each scutum with three short 

 setae and three long setae on each side, and each scutellum with 10 

 short setae. Segments 7 and 8 each with two dorsal annulets and 

 each annulet with a transverse row of setae. Segments 9 and 10 

 each with two closely placed transverse rows of setae, but dorsa not 

 divided. Each abdominal spiracle-bearing area with two setae 

 ventrally and one seta dorsally. 



Raster with teges of 28-35 hamate setae with curved tips, setae 

 scattered irregularly, five or six long setae on either side. Lower 

 anal lobe divided into two sublobes remote from each other.
